Hitting 1% battery level on your device is panic-inducing. It’s worse away from a power outlet.

Be it hiking or a camping trip, the last thing you want is to have no means of communicating with loved ones. But, with a backup charger, you don’t have to worry about your smart device being left with an empty battery.

More and more brands continue to enter the power bank market. But, what each brand brings to the table is what makes it different. Some are fast chargers while others can hold more juice than others.

After scanning through the most influential power bank brands, we came up with this list of best-rated portable chargers.

In Short

We’ve picked the ZMI USB PD Power bank as the best choice. It is a high-capacity charger that can juice your MacBook, iPhones, and Androids multiple times.

If ZMI is not compact enough for you, Xiaomi has an exciting model that is perhaps the thinnest at only 14.1mm. It can easily fit in most suit trouser pockets without creating an unsightly bulge.

1. ZMI USB PD - High-Capacity Power Bank: Editor’s Choice

https://solidguides.com/wp-content/uploads/2019/01/ZMI-USB-PD-High-Capacity-Power-Bank.jpg
  • It supports all fast charging protocols
  • It can be recharged in 4 hours
  • Offers fast 2.4Amp charging in older iOS and Android devices
  • Can charge laptops and tablets for up to three times
  • Ideal to bring in carry-on luggage during air travel
  • Comes in premium packaging to protect it from dust and scratches
  • It has a high asking price
  • It is not supplied with the lightning and USB-C adapter
check price

It is slim, sleek, and stylish — three words that we rarely see used in power banks. But, the attractive exterior is nowhere near its main attraction. The ZMI USB PD portable charger offers 20,000mAh capacity and broad compatibility with smart devices.

Functional Features

ZMI delivers 40W Power Delivery power speed. It will recharge any USB-C type device. From laptops to tablets, it is an excellent pick for a MacBook Pro, Asus Chromebook Flip, Dell XPS 13 and most 13-inch laptops. We like that this model can recharge phones for up to five times, and charge notebooks and tablets two to three times.

You can use a USB-C to USB-C charging cable for all USB-C compatible devices. This way, you will notice fast charging, but only with devices that support Power Delivery. This power bank also cuts the time it needs to recharge as it can use Power Delivery charging on its USB-C port.

You also get two USB-A ports that together deliver 18W of charging speed. The USB-A ports are ideal for Androids as they support Quick Charge 3.0, which can charge devices in as little as 20 minutes to get to 50% from 1%.

Design Features

ZMI USB PD portable charger is designed for the laptop bag or backpack rather than in your pocket. It is bulky and more cumbersome than most backup batteries weighing in at 14.2 ounces.

You will notice three charging ports on one side of the charger. The other side holds four white LEDs, a power button, and a blue LED. The blue LED shows you when the power bank is in use as a USB hub.

Snags

Unfortunately, this power bank is heavy. It may cause finger cramps if you hold it for extended periods. You will need to set it down every time you need to recharge devices.

Summary

ZMI USB PD portable charger is a distinct model. It defines its place in the industry by supporting all types of fast charging technologies. It also offers broad compatibility with a large number of devices.

2. Aibocn - 10,000 mAh Power with Flashlight: Best Cheap

https://solidguides.com/wp-content/uploads/2019/01/aibocn.jpg
  • Offers simultaneous charging of two devices on two USB ports
  • Intelligent safety protection against power surges and overcharging
  • It has a backup flashlight
  • It does not attract fingerprints
  • Excellent customer service
  • Fast charging on one of the ports
  • Offers up to three times charging of popular smartphones
  • You have to press a button for it to start charging
  • It is quite large for the capacity
check price

You not only get to top up your phone, but Aibocn Baymin charger can give you up to three full phone charges. You can take off the grid trips for a couple of days and still have your phone ready to snap a grizzly bear in the woods.

Design Features

Aibocn is a dual USB charger, which means that you can charge up to two devices at a time. Being a two-port charger, it explores quick charging and advanced technology to protect your devices. Beyond the simultaneous charging of devices, the 10,000mAh power capacity is impressive for smartphones.

It is a nice pick for iPhones, and Samsung Galaxy and other Android phones, but not so much for tablets. This is because a tablet will drain the power much faster unless you have the iPad mini 2.

The 2.1Amp port is a fast-charging port and is a nice touch for your tablet. Its other port has a 1Amp output. It has the average speed that we see on standard phone chargers that charge phones in about 2.5 hours.

With its unique Intelligent Safety Protection, you can rest assured that your devices won’t be overcharged. Not to mention that it protects itself from surges that can damage the power bank when it is charging.

Aibocn Baymin will take up to 4-5 hours to recharge. It is quite average, but that is to be expected at Baymin’s price range.

Portability and Unique Features

Aibocn Baymin looks much like iPhone 6 in terms of length but is 0.78 inches thick. It will go in a parka, jeans, or backpack pocket. Unfortunately, you can’t charge your phone when this power bank is in your pocket since it is thicker than most backup chargers at the same capacity.

Nevertheless, you get an LED flashlight that can light up dark spaces like the inside of a camping tent. Not that you can use it to find a trail in the woods, but it can serve as a backup when you need to read your map.

Snags

Aibocn has complaints about overheating. It is an uncomfortable feeling, especially if you take it out with yourself during a hot summer day.

You will notice that Aibocn has cut corners when it comes to capacity. It will lose up to 3000mAh when it is charging, which leaves you with 7000mAh to juice your devices.

Summary

Coming from a brand we respect regarding their customer service, the Aibocn has left us impressed with what it can do at its current price. It balances out the features such that you will get more out of it, including the backup flashlight. We recommend it for smartphones, but not so much for tablets.

3. POWERADD 2nd Gen Pilot 2GS - Power Bank with High Speed Charging

https://solidguides.com/wp-content/uploads/2019/01/poweradd.jpg
  • Offers automatic device detection for fast charging
  • 3-4 times of full smartphone charges and 1.5 times for tablets
  • Simultaneous charging on dual USB ports
  • Aluminum body is built to last
  • It has a 2-year warranty
  • It has multiple protection for the device and your gadgets
  • It comes only with a micro cable
  • It is bulky when carrying in a pocket or a purse
check price

You can’t beat the functionality offered by the POWERADD 2nd Gen Pilot 2GS Power Bank. Designed to provide fast-speed charging for iPhones and Samsung phones, it delivers convenience when you need it most.

Functional Features

Enjoy upgraded charging with a power bank that detects your device and delivers the fastest charging possible. With dual USB outputs, it offers 2.4Amp and 3.4Amp, which is faster compared to other high-capacity chargers.

With phones like the iPhone 8, which has 1821mAh of battery capacity, you can expect full charging up to four times. It is also a perfect match for your Samsung Galaxy S8, as well as HTC Desire 12 and many other phones.

When it comes to tablets, this POWERADD charger delivers results like the Aibocn – one full charge. Poweradd can provide 1.5 charges to the iPad mini.

Looking at its power protection system, it uses Grade A+ Li-Polymer cell premium microchips with Multi-Protect system to safeguard from overcharging and power surges. Not to mention that it is protected from over-discharging, over-current, and over-voltage.

Design Features

Poweradd has an aviation aluminum body. We expect it to last for a long time without the slightest hint of age since is scratch, dust, and impact-resistant. It recharges in 6 hours, which is longer than other power banks. Guess that’s the compromise you have to make in this price range.

As for the size, it is only 0.5 inches thick, indicating it is a tad slimmer than most portable chargers.

With Poweradd, you will get one USB cable for Android devices so you will have to bring your iPhone cable.

Snags

Poweradd is still a bit bulky. Coupled with its more than six hours of recharging, it can be frustrating if you forget to plug it in overnight and are short on time in the morning.

Summary

POWERADD 2nd Gen Pilot 2GS Power Bank is large and serves its primary purpose just right. If you don’t mind the weight and size, you are guaranteed fast charging while your devices stay protected from overcharging. We only wish you didn’t have to wait 6 hours to recharge it when it is completely drained.

4. RAVPower - 6700mAh Portable Charger: Best Mini Power Bank

https://solidguides.com/wp-content/uploads/2019/01/RAVPower-.jpg
  • 2.4Amp output for fast charging
  • iSmart technology delivers efficient charging according to the device
  • Ultra-small; it can be stored in purses and pockets
  • Allows charging of the device when it’s in use
  • It has numerous protective features for it and charging devices
  • LED indicators tell the battery level
  • Comes with only one micro USB cable
  • It gets hot when it is charging
check price

RAVPower can literally fit in the palm of your hand. It is, perhaps, the most discrete portable charger. You can take it anywhere with yourself without worrying that it will turn some heads.

Functional Features

Such a small device raises eyebrows regarding capacity. But we are glad RAVPower is keen to give you usable 5000mAh power that can deliver up to 2.5 times full charges on the average smartphone. However, it is not an ideal pick for tablets, as it cannot provide a full charge.

RAVPower has only one 2.4Amp port. It delivers fast charging, which means you can have your phone juiced in half the time it takes on other chargers. What’s more, it uses iSmart technology to identify the charging device and deliver the ideal amount of current. As such, it delivers the most efficient charge in the shortest time possible.

Four LEDs inform you of the status of this charger while it’s A+ Lithium-Ion battery is protected from over-current and short-circuiting. With its Intelligent MCU Control, it automatically stops output current when it charges.

Design Features

RAVPower is a highly portable power bank. It is palm-sized and weighs only 7.1 ounces. You can use it anywhere, but not away from civilization.

Seeing that it is only 1.6inches wide and 3.5 inches long, it stores easily in a purse and it can charge your smartphone while it’s in use. Notice that it is quite thick at 1-inch so it will not feel comfortable in your pocket even if it fits.

This is an everyday charger thanks to its extremely durable design. The metallic shell is stylish and holds strong for a decent time. No wonder it is a nice pick alongside your iPhone X, 8, 8 Plus, and every other sleek phone that needs matching up with an equally beautiful charger.

Snags

This power bank is not reliable for tablets. You will have to go with a much more capable charger like the Jackery Supercharge with a 26,800mAh capacity. RAVPower, although palm-sized, is hard to use it when holding onto a tablet because of its thickness.

Summary

We can go on and on about RAVPower, but it is because it is impressive. It is compact and stylish, and it delivers ample power for smartphones. And best of all, it does not need digging deep into your pockets to own it.

https://solidguides.com/wp-content/uploads/2019/01/xiamomi-mi-power.jpg
  • Durable metallic housing
  • Nine layers of circuit chip protection
  • 93% conversion rate
  • Can charge a wide array of devices
  • Resets back with a simple touch of a button
  • Offers two-way fast charging
  • It does not have a USB-C output
  • It does not switch from wall to battery power fast enough
check price

Xiaomi Mi Power is by far the most attractive power bank on our list. It is the size of a business card and 14mm thick. It is a charger that stays flat in your pocket.

Functional Features

Xiaomi uses LG’s and Panasonic’s 735Wh/L Polymer Cell Technology to design a small but power-dense charger. It offers 10,000mAh of power such that you can count on it to charge smartphones, digital cameras, gaming devices, and tablets.

It charges high-capacity phones like the Mi Note 2.5 times, and it charges the iPhone 8 3.5 times. Xiaomi Mi Power provides one full charge for tablets. It is like most 10,000mAh power banks.

Xiaomi boasts world-class chips that top the game when it comes to charging and discharging efficiency. It has an improved charging conversion rate that ensures it only loses 1000mAh while charging. It leaves you with 9000mAh of usable charge.

Xiaomi Mi Power has incredible nine layers of top-of-the-line chip protection. It has good temperature resistance, as well as input/output overvoltage protection. It offers short circuit protection, overcurrent protection, and more.

Design Features

Xiaomi Mi Power boasts a minimal design. It is 5.1 inches long and 0.5 inches thick. It is the size of most smartphones, so it will not feel bulky in your hand or pocket. It has a high-quality aluminum build between the top and the bottom, which have construction from equally durable plastic.

You get two-way charging with its dual outputs. One is a fast charging 2.4Amp USB-A port, and the other is a 1Amp port. There’s also a power button and four LED lights that show the power level of the charger.

Snags

Xiaomi Mi Power may need charging overnight when it is critically low on power. Even if it is indicated to require 4 hours to a full charge, it applies when the power bank is not totally drained.

Summary

You can’t go wrong with the Xiaomi Mi Power if you are looking to charge different devices at your convenience. Whether at the office or out on a road trip, it will come in handy when you need it most. You will appreciate its slim design, conversion rate, and charging efficiency no matter the USB device you have.

6. AUKEY - Power Delivery Power Bank with Quick Charge: Easiest to Hold and Use

https://solidguides.com/wp-content/uploads/2019/01/aukey.jpg
  • Allows simultaneous input and output charging
  • Quick Charge works on the latest Qualcomm-compatible smartphones
  • It has four ports for multiple device charging
  • Small and lightweight for maximum portability
  • Protected from overheating and overcharging
  • It is not ideal for tablets
  • Its fast charging supports only compatible phones
check price

If you’re looking for the most comfortable power bank, AUKEY has got you covered. It is a backup charger that you can easily hold in your hand and use your phone at the same time. This attribute is all thanks to the flat and slim design.

Functional Features

AUKEY is aimed at smartphones mostly because of the Quick Charge 3.0 feature. If your phone supports Qualcomm’s fast charging technology, you can take advantage of it using this charger. Due to quick charging, the conversion rate of AUKEY is a bit worse as it can go from the typical 7000mAh to 6000mAh.

You may never get a full recharge of your tablet using this power bank. It also supports Power Delivery smartphones like iPhone XS and Google Pixel.

This power bank offers three ways to recharge, which include a lightning input port, a USB-C port, and a Micro-USB port. With the USB-C port, you will be able to use a PD or Quick Wall charger to recharge it in a faster time than with other wall chargers.

Design Features

AUKEY is plain for the most part except for the four LED indicator lights. On one side, you have all the charging ports while the other has the input port and the power button. We like that it does not overheat when it is charging and that it also protects devices from overcharging.

The size of this power bank is desirable for everyday use. It is 4.2 inches long and 0.9 inches thick. You can tell from its 2.7-inch width that you can hold your phone on it while it is recharging.

Snags

AUKEY comes in a plastic housing that scratches easily. We would have loved to see a durable case to protect it since it is mostly used on the go. Also, it requires nine hours to recharge, which is quite long.

Summary

AUKEY manages to stay relevant in the crowded power bank market owing to its support for Power Delivery and Quick Charge. It offers fast charging for most modern devices, so you don’t have to wait all morning to use your phone. Despite being a bit more expensive than its competitors, it is well worth the price.

7. RAVPower USB-C - Portable Charger: Best USB-C Power Bank

https://solidguides.com/wp-content/uploads/2019/01/RAVPower-usbc.jpg
  • It takes only 4 hours to recharge
  • Can charge smartphones up to four times
  • Supports simultaneous charging on both ports
  • Comes with a micro USB cable
  • It has a 16mm body that can fit in pockets
  • Solid build
  • It does not come with lightning or Type-C cable
  • Does not offer Quick Charge and Power Delivery technology
check price

RAVPower Portable Charger is a useful model to own. As much as it has a midrange power capacity, it allows simultaneous charging on its type C and micro USB ports. This way, the power bank can charge devices fast and save you time in the process.

Functional Features

With 10,000mAh power, RAVPower will recharge your iPhone X up to 2.2 times, iPhone 8 3.3 times, Samsung S8 two times, and iPad Air 0.7 times. It is a credible companion for outdoor ventures as it gets you using your devices for longer without a power outlet close by.

RAVPower has the USB-C port with 3.0Amp charging speed and a USB-A with a 2.4Amp fast charging speed. It does not support Quick Charge, but it allows charging of devices in half the time it would take on their chargers. What’s more, it allows simultaneous charging, which allows 3.1A max charging speed.

You have two ways of recharging this power bank. The USB-C port can charge it, but it also has the micro USB input with a 3.0A charging speed.

Design Features

RAVPower has an ergonomic design that allows using the power bank and your phone at the same time. The 16mm body is ultra-thin such that you can store it in your pocket, bag, or purse. It also has a high-quality build that is protected from short circuit, overcharging and over-discharging.

Its most attractive feature is that you can bring it in your carry-on luggage to a plane. If you are taking on an international business trip, no need to worry about power outlet compatibility as it is universally accepted.

Snags

Fast charging is not supported in iPhone 8, 8 Plus, and X. With a maximum output of 15W, it is limited to normal speed charging for these phones. And, if your smartphone is not USB-C compatible, it cannot take advantage of the fast charging.

Summary

For a mid-capacity power bank, RAVPower has more to offer than other portable chargers in its class. Android phones stand to benefit the most, while iPhones and tablets can also recharge on this device if you don’t mind being a little patient. From its conversion rate to the ergonomic build, there’s real value in RAVPower.

8. Jackery Mini - 6000mAh Power Bank with Built-In Lightning Cable

https://solidguides.com/wp-content/uploads/2019/01/Jackery-Mini-.jpg
  • Built-in lightning and USB cables
  • Built-in battery is UL certified
  • Supports pass-through charging
  • Sturdy construction improves durability
  • Offers fast charging for both iPhones and Android phones
  • Speeds slow when device nears a full charge
  • Their customer service is painfully slow
check price

Travel with the convenience of a fast charger for your iPhone with the Jackery Mini 6000mAh Power Bank. Its built-in lightning cable and a micro USB cable are the most intuitive features. You only need to pack the power bank without worrying about the cable.

Functional Features

Jackery Mini 6000mAh is a fast charger. It takes only 1.5 hours to recharge iPhone 6 Plus, 7 Plus, and 8 Plus. And, if you own an iPhone X or Xs, it is going to take only 2.5 hours instead of the usual 3.5 hours that it takes. Its charging time gives you a pretty good idea of how long it’s going to take to recharge Android phones.

For example, Samsung S8 will fully recharge in 1.8 hours. We noticed that it takes longer to reach 100% with this charger since it can bolt from 1% to 70% in about 30 minutes. Unfortunately, the remaining 30% charge slowly.

Jackery uses power dense Panasonic cells to deliver up to 6000mAh of power. It will recharge most smartphones up to two times or more. If you don’t fancy the two built-in charging cables, you can also use the provided micro USB to charge from a wall plug.

Luckily, it is possible to use the three charging methods simultaneously. It comes in handy when you have an Android and iPhone that you want to juice up at the same time over pass-through charging.

Design Features

We like that Jackery Mini can easily fit in your pocket. It is 5.51 inches in length and 1.18 inches thick. You can expect a bulge when wearing tight jeans since it is thick. You will also not be able to charge your device when Jackery is in the pocket.

The two built-in cables stow away fast and easy after charging. However, you have to contend with the fact that they are short and you cannot charge an iPhone in its case. But, we do like that the cables are flexible such that it is possible to stack the power bank at the back of your phone.

Snags

Most people who have received a malfunctioning power bank have had problems reaching Jackery. There are complaints of poor customer service that we would like to see addressed considering the price of the charger.

Summary

Jackery Mini 6000mAh is quick to give you a highly-functional power bank. It favors iPhone users over Android since the lightning cable is Apple MFI certified. Except for the cables being short, being able to charge devices in half the time is one of the main reasons to get the Jackery 6000mAh backup charger.

9. Anker PowerCore II - Ultra Slim Power Bank

https://solidguides.com/wp-content/uploads/2019/01/Anker-PowerCore-II-.jpg
  • Offers full-speed charging for Androids and iPhones using Power IQ 2.0 technology
  • It delivers over 3.5 times of charging for most phones
  • Seamlessly slim to fit in tight pockets
  • Receives multi-protect safety system
  • Soft silicon surface protects phones
  • It can recharge in four hours with a quick charger
  • It is not compatible with all USB-rechargeable devices
  • It requires using an original Apple cable for efficient charging of iPhones
check price

Anker PowerCore II represents what a power bank should be all about. From the slim, ergonomic design, to its high-capacity and compatibility, it gives you value for every dollar.

Functional Features

It is nice to see a power bank that steps out of the comfort zone with its Power IQ technology. It is lighter and smaller because it uses one circuit instead of multiple chips to support broad charging. What you get is a portable charger that can recharge devices faster as it recognizes your device for efficient charging.

Anker PowerCore II can charge popular smartphones like the iPhone 8 up to three times on a single charge. The charger can recharge your devices universally at the fastest speed that a particular phone supports.

We like that this power bank can be recharged in four hours with a Quick Charger. But, if you don’t have a quick charger, you will have to wait 10 hours with a 5V 1A charger and 5 hours 40 minutes with a 5V 2A charger.

Anker’s MultiProtect Safety System protects this power bank from power surges. It also keeps your devices safe from overcharging.

Design Features

Although it is slim, Anker PowerCore II is still chunky. It has a soft silicone back that helps to cushion your phone. Also, you will notice it is grippy and that it resists fingerprints. Apart from the superior exterior, you also get to enjoy a durable product that is dust and impact protected.

Anker PowerCore II offers one USB-A output and one micro USB input port. It allows you to charge one device at a time.

Snags

The lifespan of Anker PowerCore II has come under fire after by unsatisfied customers. Their complaints mentioned the device failing to charge after only a couple of months. It seems that there is a bad batch on the market. But, Anker has fantastic customer service that is quick to replace a faulty power bank within the warranty.

Summary

Anker PowerCore II is at the center of style and innovation in the power bank world. Its PowerIQ 2.0 technology, alongside its high capacity, propels it to the top of the competition as it is highly reliable. If you are looking for convenience, look no further than the Anker PowerCore II.

Functional Features

Jackery Supercharge offers 45W fast charging speeds and can be recharged at the same rate. The charger has one USB-A port. It is limited to charging only one device at a time. Fortunately, it can charge devices faster, so you won’t wait for hours to get your phone up and going.

This power bank can charge most 12-inch and 13-inch USB-C laptops for 1.5 times owing to its high capacity. It has a massive 26,800mAh capacity. You can count on the power bank to recharge your devices a couple of times while you’re away from civilization.

This charger meets TSA standards for being taken on airplanes. You have peace of mind knowing you don’t have to worry about your laptop’s power level when writing a report in flight. Not to mention that this power bank can also charge the Nintendo Switch while it’s being played.

Design Features

It is clear that this is a heavy device at 15.8 ounces. You will want to store it in a laptop bag or your hiking bag as it will not fit in most jeans pockets. We like the streamlined appearance that gives it a subtle look. It won’t stand out while you are completing an article at the coffee shop.

Jackery Supercharge includes a screen that tells you the charge left in numerical terms. It is a unique aspect since we are used to LEDs that can be a bit vague when representing the correct power percentage.

Snags

This charger is not compatible will all laptops including the Dell Inspiron 7000, Samsung Notebook 9, Thinkpad Yoga X1, Samsung Notebook Pro 13.3-Inch, and Thinkpad Yoga 910. You will want to check compatibility with your laptop before deciding whether it is ideal for your needs.

Summary

Jackery Supercharge allows you to hit the road without a single worry about a dead battery for all your USB-C devices. Its power capacity, combined with a 45W wall charger, allows you to enjoy your devices without the charging-related stress.

Most of the portable chargers come with the information related to its power. The information comes in the form of a number that tells you the number of mAh (milliamp-hours) of the portable charger.

The number directly relates to the power of the charger – bigger number means more power. Plenty of portable chargers are capable of 2000mAh, but you should go for more. Good portable chargers offer over 10,000mAh, while the best ones offer 20,000mAh and then some.

Basically, 10,000mAh should be enough to charge an iPhone up to 3 times. Always go for a higher number, and try to avoid cheap power banks with only 2000mAh.

Power Output

You will be using the USB port to charge your smartphone or a tablet. But, the amount of power that a USB port can provide varies.

The power output is shown in amps. Basically, if you see a power bank that offers 1 amp of power, then you can assume that the charging is slow.

On the other hand, 2.4 amps are enough to charge a smartphone quickly. Some of the portable chargers are capable of charging two devices at the same time. Those portable chargers have a power output of 3.4 amps and more.

To put it short, look for a portable charger that offers at least 2.4 amps of power output.

USB Ports

More powerful portable chargers offer you to charge more than one device at the same time. They manage to do it by giving you two, or more, USB ports.

So, if you want to charge your GoPro and your tablet at the same time, look for a power bank that comes with more than one USB port. Bear in mind the importance of power output. Don’t buy a portable charger that offers only one amp of power with two USB ports.

Cables

It doesn’t matter if your portable charger is powerful if the cables are low-quality. High-quality cables allow you to power your devices quickly, and protect from power surges and overheating.

Your power bank needs to be charged as well. So, make sure that the cable for charging your power bank is of high quality.

When it comes to the cable that connects to the device you want to charge, the same rule applies. The problem is that some power banks come with a hard-wired cable. Since the cable can’t be removed, the portable charger is less versatile.

The best power banks allow you to switch cables, so look for a model that lets you use different cables. That way you can easily switch a faulty cable with a new, high-quality one.

Size

Since power banks are portable devices, the size plays an important role in choosing a high-quality product.

You will be carrying your power bank with you, so make sure that you have the means to carry it with you. Smaller ones can fit into your pocket, but the larger ones are way too big to carry around in a pocket. There are some “mini” versions of power banks that are a great fit for small pockets. Unfortunately, most of the power banks that can charge two devices require to be carried in a backpack or a purse.

Warranty

The best power banks come with a warranty that not only covers the power bank but connected equipment as well.

You will notice that most of the warranties are limited, which means that they cover the portable charger only for a limited period of time. Some companies give you a limited lifetime warranty, which may vary from one company to the others.

If you can, always look for a power bank with a connected equipment warranty. That way, you can have your connected devices repaired if they get damaged during the charging. Bear in mind that connected equipment warranties come with clauses that you should check out carefully.

Quality Assurance is Important

Never purchase a portable charger that doesn’t come with quality assurance. You don’t want to compromise your safety for a lower price. Make sure that your new power bank is safe by checking out whether certain tests have been performed on it.

  • Overcurrent protection: Overcurrent protection devices protect against overload current and short-circuit current. Always make sure that your new portable charger comes with overcurrent protection. Overcurrent protection protects the circuitry of both the charger and your device.
  • Efficiency: Go for a power bank that is proven to waste less energy. You should also make sure that it doesn’t have a high operating temperature. Both of the efficiency factors give the power bank a longer life expectancy.
  • Overvoltage protection: This feature shuts down the power supply if the voltage exceeds a preset level. In layman’s terms, overvoltage protection prevents damage to the electronic components.
  • Overcharge/overdischarge protection: Good portable chargers monitor charge states to prevent overcharge and/or overdischarge. This is a great feature since it prolongs the life expectancy of your devices.
  • Heat: High-quality power banks manage to pass rigorous temperature tests. They can perform well in hot, as well as cold conditions. So, before you commit to a purchase, make sure that you are buying a device that has passed extreme temperature tests.
  • Certifications: Make sure that your new power bank complies to certain laws, policies, standards, and specifications. Simply look for logos that show you that the device complies with legal standards of safety. Most of the time you will see an FCC (Federal Communications Commission) logo, or an ETL (Electrical Testing Labs) logo, which shows that the device is safe to use.
