Phones have evolved at a rapid pace over the last decade, they became a lot faster, more capable, got greater storage capacity and a lot more features.

You may think that this is the fine example of the Moor’s law in practice, yet if you look at the battery performance – it could not be further away from the truth.

1. Best Small Power Bank – Jackery Mini

Jackery Mini which is also known as Jackery Force65 is the smallest power bank we have on the list, in fact, Jackery claims it to be the smallest power bank in the world.

Jackery has managed to build quite a reputable name in the space of a portable and solar power.

The company founded in Silicon Valley uses quality parts from world-class manufacturers such as Panasonic, Samsung, Texas Instruments and many others.

The Jackery Force 65 is the best small size battery pack on the market. There are no other power banks of that size with LED charge indicators.

The power bank’s case is made of anodized aluminum giving it a premium look and a solid feel. It features the scratch resistant coating which should prolong the battery pack’s visual appeal. We also found the rounded cube shape to be more practical compared to the cylindrical shape, commonly seen in other portable mini chargers as it prevents the battery pack from rolling.

Jackery Mini is an ultra-compact power bank which is only slightly bigger than a lipstick. Armed with a 3350 mAh lithium polymer battery – it packs a charge capable of completely recharging most mobile phones. There are no fancy features offered by this battery pack as it is as basic as it gets. It has one USB port with a permanent charge current of 1A, which is understandable given its size. At the same time, finding the LED charge indicator on a battery pack of such a small size is uncommon, yet very handy.

We did, however, find a number of reported cases of battery overheating or having an inconsistent charge speed. It does not appear however in the recent customer experiences, as we believe the Jackery have now resolved the issue.

Bottom Line
Jackery Mini is not your everyday generic power bank for any type of use. It is a great companion for emergency top-ups and occasional use as it stores a reasonable amount of power and takes close to no room to carry. There are many alternatives available on the market, yet the Jackery Mini in our view is qutie comfortably the best small power bank 2019 has to offer.

2. Best Power Bank For iPhone – Anker PowerCore Slim 5000

PowerCore Slim 5000 has been designed with the focus on ergonomics and portability. It does not store insane amounts of power, yet it does provide a quick and comfortable way to charge your phone on the go.

It has won a prestigeous Red Dot Design Award as it has been recognized for its incredible ease-of-use and ergonomic qualities.

The battery packs 5000mAh of power in a sturdy and slim body. The power bank can be recharged with a 2A charge using your iPad or other 2A USB adapters. Alternatively, you can opt for Anker USB Wall Charger.

Anker PowerCore Slim is the best best power bank for iPhone, especially if you like to carry it in your jeans pocket

PowerCore Slim 5000 has only one USB port with 2A output and an integrated PowerIQ technology which ensures the quickest charge possible.

Depending on the mobile phone you will find the battery pack capable of fully charging your mobile phone between one and two times. The battery pack incorporates safety switches that protect the connected devices from surges, which is now a standard across all Anker power banks.

The body cover is made of a high-quality rubber which prevents the phone from slipping off and has a nice and comfortable feel to it. Although PowerCore Slim 5000 has an ergonomic design in general, we found that it works better with iPhones as the battery pack is the same size as iPhone 6 and 7. Although it works slightly less seamlessly with other phones, we still believe that it is the best power bank for smartphone charging in general. Wearing tighter jeans or having a thicker phone will definitely impact your pocket carrying experience, so you may want to keep that in mind

The other handy tip would be to have a short USB cable handy, this way the connection between your phone and the power bank is tight and comfortable with no cords hanging off.

Bottom Line
Overall, PowerCore Slim 5000 is one of the best pocket power companions you can buy in 2019. Moreover, if you are an Apple user, this is perhaps the best power bank for iPhone you will ever find. So if you like carrying the charger in your jeans whilst your phone is being charged – the PowerCore Slim 5000 will get the job done for you quite comfortably.

3. Best Portable Power Bank – Jackery Bolt 6000

Jackery Bolt 6000 has a  great build quality and is made of brushed aluminum with plastic sides. Not only it makes the power bank look great, but it also makes it more durable.

With 6000mAh battery capacity and reasonably compact size, Bolt 6000 features an amazingly practical balance between power, portability, and convenience.

The power bank uses A-grade quality Panasonic lithium polymer cells, which have enough capacity to charge most of the mobile phones twice and up to three-quarters of an iPad battery.

Jackery Bolt 6000 is the top battery pack if you need both lightning and micro USB connections in a single unit.

The unique feature that makes the Bolt 6000 stand out are the integrated charging cables. You get the MFI-certified lightning cable on one side and micro USB cable on the other, which works for both iPhones and Android devices. It also comes with a standard USB port, in case you need to use your own cable. That comes to three ports in total, which is great as most of the competition has one or two ports in that size.

Jackery Bolt 6000 supplies up to 2.4 amps of power, which is shared between the ports. This means that charging one device will be quicker than charging two or three devices at the same time.

The battery pack takes around four hours to charge on a 2A charge, which is very reasonable. It also supports pass-through charging, so whilst you charge your power bank, it can charge up to 3 devices at the same time!

In terms of additional features, it is worth mentioning that the power bank comes with four LED lights integrated into the body providing a surprisingly bright light. This is not a vital feature, yet a handy one as you never know when you’re going to need it.

Bottom Line
Jackery Bolt 6000 is a hugely practical, portable and stylish portable battery charger that hosts features usually found in bigger and more expensive power banks. If you have various devices to charge and prefer not to carry the cables around –  Jackery Bolt will be your very handy companion.

4. Best Power Bank for Travel – Belkin Mixit

Like most Belkin devices, Mixit carries good design lines and a solid build quality.

The power bank comes at a small premium (like most Belkin products) but in our opinion, it is a premium well worth paying.

The casing has an aluminum finish which makes the power bank look high end and durable.

Belkin Mixit has two USB output ports, one producing 1 A of power and the other offering 2.4 A which can almost be considered as a fast charge feature.

There are four green LED lights positioned next to the USB ports indicating the remaining battery capacity. We found it helpful to plan the charging cycles a little bit better.

Belkin Mixit is the best battery charger you can get for a general use. It is sturdy, stylish and has amazing capacity.

The battery pack hosts enough power to charge your mobile phone from two to three times.

Like most Belkin products, Mixit comes with Belkin Connected Equipment Warranty as an additional reassurance for concerned customers. This is a nice bonus that basically protects your connected devices from any potential damage caused by the power bank.

Bottom Line
Belkin Mixit does a great job at charging your mobile phone and other portable devices. It is a general purpose power bank with no premium features, but with a premium feel and build quality. Lightweight design and good capacity make it one of the best power banks for travel and commute.

5. Best Rugged Power Bank – Zendure A2

Zendure A2 has undergone a number of upgrades and the latest generation comes with 6700mAh capacity which is more capable and affordable than ever.

The original focus on strength and toughness has not changed as the battery pack is made from a crushproof PC/ABS composite material. In fact, it is not only tough but also stylish, which quite often are two mutually exclusive attributes.

There is only one port on the power bank, but a capable one. It is rated at 2.1A which is equivalent to quick charging without the actual support of Qualcomm’s Quick Charge feature.

Zendure A2 is on the best portable power banks around. It is also the toughest power bank on the market, by a mile.

The manufacturer claims that the power bank has 80% efficiency rate which is in line with the numbers observed throughout our testing. This gives you 5360 mAh of pure usable power. Zendure A2 can be charged in under four hours, which is a pretty good result compared to the competition. Moreover, the smart technology integrated into the unit retains 95% of the charge for up to 6 months.

Bottom Line
Zendure A2 has found a sweet spot and made a power bank which is durable, efficient, stylish and reasonably affordable. If you are after something tough that also looks good – you can’t go wrong with Zendure A2, it is the best rugged power bank you can get in this size.

6. Best Power Bank for Camping – Goal Zero Venture 30

Goal Zero Venture 30 has been designed with outdoor use in mind. It has an ultra-rugged case, multifunction torch (light and stroboscope) and a vivid color frame.

The power bank features two 2.4A USB outputs cleverly integrated into the body that support simultaneous charging. The smart charge feature determines the quickest way to charge your battery with up to 4.8 amps being available at your disposal. It is great to see both ports supporting a higher charge rate, which is uncommon amongst the competition.

There are 2 buttons on the battery pack to check the charge level and turn on the flashlight.

Goal Zero Venture 30 is probably the best rugged battery pack you can find on the market. It is tough, packs a lot of power and has an LED flashlight.

Although the Venture 30 is advertised as waterproof, it is only partially correct. It is IPX6 certified, which means that it can handle high-pressure jets from all angles, but it has not been designed for submersion.

The battery pack can be fully charged in four hours using the USB or around ten hours (under the direct sunlight) using the Goal Zero’s solar panel (sold separately).

Bottom Line
Goal Zero Venture 30 is not the cheapest option out there, but if you need something solid for the outdoor use, it is worth paying the premium. The case is remarkably strong and water resistant which ensures that you have the power on hands even in the most demanding conditions. Coupled with a solar recharging kit, the Venture 30 is one of the best power banks for camping, hiking and outdoor use in general.

7. Best Value Power Bank – Aukey PB-N50

Aukey PB-N50 is a convenient power bank with a simplistic design, slim body and the scratch resistant coating.

Despite a reasonably compact size, the battery pack is capable of storing an impressive 10000mAh of power.

You can fully recharge PB-N50 in around 4 hours which is very reasonable compared to the competition.

There are four minimalist white battery level lights which look subtle and sleek but are practical at the same time.

Aukey PB-N50 is one of the top battery packs of 2018 as far as value is concerned. We found it to be the perfect balance between portability, practicality and power.

The power bank features two charging USB ports that allow simultaneous charging. Ports provide 1A and 2A of permanent power respectively which does not change based on the number of the connected devices.

To protect the connected devices, Aukey PB-N50 comes with built-in safeguards against excessive current, overcharging, and overheating.

Bottom Line
Aukey PB-N50 battery pack is a very solid performer. It is simple, strong, compact and packs way more value than its price tag suggests. It is perfect for day to day use and easily fits in your back pocket. If you are looking for an affordable 1000 mAh portable power bank in 2019 – this is among the best examples available.

8. Best Budget Power Bank – Anker PowerCore 10000

Anker is a reputable brand in battery packs which is known for its simplicity and reliability and Anker PowerCore Speed 10000 is not an exception.

Although the power bank hosts 10000 mAhs it is remarkably compact and lightweight.

The power bank comes with Voltage Boost, Quick Charge 3.0 and PowerIQ technologies that allow for a quick and reliable charge which is uncommon in the budget power bank range.

Anker PowerCore 10000 is one of the best USB battery packs you can find on the market if you need something for a general use. It is highly reliable, lightweight and slim.

We are a little disappointed by not having the pass-through support and only one charging port, yet the benefits far outweigh the drawbacks in our opinion.

There are not many battery packs that can compete with the value proposition of Anker PowerCore Speed 10000, yet Aukey PB-N50 (reviewed above) is one of them. We slightly prefer the latter, simply due to having an additional USB port and a pocket-friendly design, but you can’t go wrong with any one of them.

Bottom Line
Anker PowerCore Speed 10000 battery pack is a very strong general purpose power bank. It features a strong plastic body which packs more power than we had expected. Its asking price puts it among the best budget power banks on the market. If you need an affordable, reasonably compact yet capable 1000mAh power bank – Anker PowerCore Speed 10000 is one of the best value power banks around.

9. Best USB-C Power Bank – Mophie Powerstation Plus

Mophie Powerstation Plus is a sleek design external battery specially designed for on the go charging.

It features a slim profile, built in hideaway cable and packs enough punch to charge most of the portable devices you might carry around.

It has a visually appealing design that follows iPhone lines. The body features aluminum outer edges and rugged body.

The battery pack hosts 6000 mAh of electric power and features two USB-C and USB-A ports that allow simultaneous charging. 

Samsung Fast Charge Battery Pack is one of the best portable phone charger of 2018. It is designed specifically for a mobile phone and can charge it in no time.

Both ports support fast charge with USB-C delivering up to 18W and USB-A up to 15W of power. Compared to the most typical USB wall charger that has 5W, Mophie Powerstation Plus can charge your portable device up to three times quicker.

In addition to supporting a pass through charge from the wall socket, the power bank has a smart priority charging built-in. It ensures that the connected devices get charged first and only then the power bank itself. 

Bottom Line
Mophie Powerstation Plus is a sleek and stylish battery pack with integrated cable. It was specifically designed for mobile phone charging using USB-A and USB-C connections. With built in Fast Charge the power bank can recharge the supporting devices three times faster than the standard wall charger. If you are looking for the best portable power bank for your Android smart phone, it does not get any better.

10. Best Slim Power Bank – Xiaomi Mi Power Bank Pro

If you are on a lookout for an affordable battery pack with 10000mAh capacity, Xiaomi Mi Power Bank Pro is worth your consideration.

The design features a high-quality aluminum body with quality white plastic on both ends. It has a sleek, stylish and modern look that gives the battery pack a premium feel.

With the weight of only seven ounces and a slim, and ergonomic profile the battery pack can easily fit in your pocket.

If you need a massive power packed in a slim body then Mophie Powerstation 8X is the top choice. It can easily slide into your backpack and provide an extraordinary capacity.

Xiaomi Mi Power Bank Pro offers an impressive 10,000 mAh of capacity with 91% or battery efficiency.

There are two ports with micro-USB and USB-C connections that can be used for parallel charging. With QuickCharge 2.0 and 3.0 support, the battery pack can intelligently send up to 18W of power to speed up the charging process. For example, charging iPhone 8 only takes around two hours.

There is also a handy power button that brings up four white LED lights to indicate the remaining charge capacity.

In the box, you will find a USB-A to micro-USB cable and a micro-USB to USB-C adapter which is attached to the cable. Being able to change between the connectors easily is a great feature, and since the cords are connected, they won’t be misplaced easily.

Despite being a budget battery pack, Xiaomi Mi Power Bank Pro supports pass-through charging. This means that the power bank can continue charging connected devices while being charged from the wall socket itself — quite a handy feature, especially when traveling.

Bottom Line
Xiaomi 10000mAh Mi Power Bank Pro is one of the most affordable battery packs on the market but it doesn’t skimp on quality or features. With a slim profile, sleek design, QuickCharge support and solid charging performance, it would be hard to find a better value power bank for your phone or tablet back up.

11. Best Power Bank for Multiple Devices – RAVPower 16750mAh

We have seen many quality power banks made by RAVPower and RAVPower 16750Mah has to be one of the most impressive ones.

It has highly efficient LG/Panasonic lithium-ion cells, great build quality and a sleek design.

Yes, some may find it a little bit bulky and heavy, yet in my opinion, it packs more than meets the eye and is well worth the top spot in its category.

The two USB ports can provide the maximum output of up to 4.5A individually or around 3.0A when being charged simultaneously.

RAVPower 16750mAh is a top high capacity battery pack for your demanding needs, It is mighty, looks good and has a great build quality.
RAVPower 16750Mah has a built-in iSmart technology, which automatically determines the charge rate most applicable to your device to optimize the charging process and extend your battery’s life. It also comes with a light, in case you need a hand getting it connected to a device in the dark. The only letdown we found is the excessively long charge time. Our test showed that anywhere between 7 and 9 hours are required to fully recharge the battery pack.
Bottom Line
With so many great features, RAVPower 16750Mah is worth the attention of any power demanding user. The battery pack looks, feels and performs outstandingly. Multiple device parallel charging and built-in iSmart technology make it one of the best power banks for larger devices or multi-device use.

12. Best Power Bank for Laptop – DBPower Q100

DBPower Q100 is by far the largest portable energy storage in our review.

Due to its size and weight, the power bank is not for general use as it is both too heavy and bulky to carry on a daily basis.

Yet, if the battery capacity is what you need – you will be hard-pressed to find a better and more capable companion.

The power bank has been designed to cater for a very wide range of devices, starting from the wireless headsets to mobile phones and laptops.

This is a perfect battery storage for someone who has limited access to power and needs the maximum capacity to get his multiple gadgets going.

DBPower Q100 is the best high capacity power bank in our review. It is the ultimate power bank if you need to store the maximum amount of charge!

DBPower Q100 has two USB ports that are able to charge two smartphones at 5V/2.2A. On top of that, it comes with an AC port, so that you can use your wall charger to charge your device. The power bank as massive capacity, sufficient to charge your big size portable devices such as laptops or ultrabooks.

Bottom Line
If you are looking for the Juggernaut of power banks that performs well – you have just found one! The DBPower Q100 can charge multiple small to large size portable devices at the same time. Its generous capacity makes it the best power bank for laptop and ultrabook use.

How do we test Portable Battery Packs?

To have a good idea whether the power bank delivers on its promise or not, you either need to go through some rigorous use or have the sophisticated equipment to help you out, or even better – both! We’ve learned not to trust manufacturer’s claims as quite often they are far from reality. Below are a couple of important points for you to keep in mind when choosing a power bank:

  • Keep in mind the Quick Charge 2.0 or 3.0 compatibility with your phone. Paying for a power bank that supports Quick Charge 3.0 whereas your phone supports only Quick Charge 2.0 could be a waste of money.
  • Do not trust the ‘charges the battery x times’ type of claims. There are many factors that determine the number of times you will be able to charge your phone with a power bank, including your phone’s battery condition.
  • Check the power bank’s input voltage and current throughput. The lower the number is, the longer it will take to complete the charge. Values of 5V/1A (which corresponds to standard USB rates) or below would result in slow charging.
  • An ability to charge the power bank whilst it is charging the other device(s) is termed as a pass-through charging. It may not sound important in the first place, yet in practice, it is more than handy.

The main five aspects we consider when reviewing power banks are:

  1. Capacity to Size ratio
  2. Battery life
  3. Features
  4. Ports and connections
  5. Value

We will help you to make your selection process easier and faster, but essentially you need to decide on a set of features that matter to you the most to get the perfect fit. Below we have the top power banks of 2019 in various sizes, capacities and features.

Frequently Asked Questions

What capacity power bank do I need?
It depends on the devices you are planning to charge. The easiest way to work it out is:
  1. Find the mAh rating for the device you are planning to charge (e.g. 2000 mAh)
  2. Add 20% that will be lost in the process of charging (e.g. 2000 + 20% = 2400 mAh)
  3. You will get the power bank’s capacity required to fully recharge the battery of your device once
How long does it take to charge a power bank?
This directly depends on two factors – power bank’s capacity (mAh) and the electric current produced by the charger (amp). The higher the capacity, the longer it will take to charge. The bigger the power of the electric current is, the less time it takes to recharge the battery.
How else do people refer to a power bank?
It can be referred to as a power bank, battery pack, portable charger, power cell and even a fuel cell.
What type of cells are used in power banks?
Generally speaking, it is either lithium-Polymer (Li-Po) or Lithium-Ion (Li-Ion).
  • Li-Ion batteries are cheaper to make and have their efficiency decrease with age.
  • Li-Po batteries are more expensive to produce and last longer.
How does fast charging work?
Fast Charging is a technical process that may be hard to explain without using technical terms and sounding a little geeky. The key to the concept is the charge controller that oversees the charging process. In general, higher voltage and electric current charge batteries faster, but not all batteries can handle the intensity and fluctuations. The charge controllers job is to make the charging process safe by protecting the battery against current spikes. Here is a brief video explaining the battery fast charting process in slightly more details:
How much of the actual capacity do power banks retain?
If you maintain the power bank well, you can expect from 80% to 90% of the nominal mAh efficiency to be retained.
