1. Jackery Mini – Best Mini Power Bank

The Jackery Mini is the smallest power bank we have on the list, in fact, Jackery claims it to be the smallest power bank in the world.

The Jackery have managed to build quite a reputable name in the space of a portable power.

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

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.

The 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
In summary - the 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 portable charger 2018 has to offer in the smallest possible size.

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

The 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.

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

The battery packs 5000mAh which can be replenished with a 2A charge using either your iPad or Anker’s USB chargers twice as fast. 

Anker PowerCore Slim is the best best power bank for iPhone, especially if you like to carry it in your jeans pocket
The 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 to have enough capacity to completely charge your mobile phone from 1 to 2 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 the 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, the PowerCore Slim 5000 is one of the best pocket power companions available in 2018. 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. Jackery Bolt 6000 – Best Portable Power Bank

The 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, the 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.

The 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
The  Jackery Bolt 6000 is a hugely practical, portable and stylish device that carries 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. Belkin Mixit – Best General Purpose Battery Pack

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

The unit comes at a premium (like all Belkin products) but it is a premium well worth it.

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

The 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.

The four green LED lights positioned next to the USB ports are designed to indicate 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 power bank charge is sufficient to charge your mobile phone from two to three times.

The power bank 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.

5. Zendure A2 – Most Durable Battery Pack

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

6. Goal Zero Venture 30 – Best For Outdoor Use

The 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.  The power bank 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
The 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. Highly recommended for campers and hikers!

7. Aukey PB-N50 – Best Value Power Bank

The PB-N50 is a very practical power bank with the simplistic design, slim body and the scratch resistant coating.

There are two charging USB ports that allow simultaneous charging but provide different amperage. The first port has a permanent 1A, whereas the second has 2A, also permanent.

The power bank has 10000mAh capacity which is remarkable for its size and weight.

The total recharge time of PB-N50 is around 4 hours and we found it to be very reasonable compared to the competition, especially having a 1000mAh capacity.

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.
Bottom Line
The PB-N50 battry pack is a very solid performer. It is simple, strong, compact and packs way more value than its price tag. It is perfect for day to day use and easily fits in your back pocket. If you are looking for an affordable 1000mAh portable power bank in 2018 - this is the best example available.

8. Anker PowerCore 10000 – Best Budget Power Bank

Anker is a reputable brand in battery packs which is known for its simplicity and reliability.

The Anker PowerCore Speed 10000 is not an exception as it packs a simple yet a very capable package.

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.

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.

Bottom Line
The PB-N50 battery pack is a very solid performer. It is simple, strong, compact and packs way more value than its price tag. It is perfect for day to day use and easily fits in your back pocket. If you are looking for an affordable 1000mAh portable power bank in 2018 - this is amongst the best power banks that manage to combine simplicity, practicality and sheer value so well.

9. Samsung Fast Charge Battery Pack – Best For Smartphones

The Fast Charge Battery Pack from Samsung is a portable and very capable lithium-ion power bank for your mobile phone.

It contains 10200 mAh of fast charging capacity at your disposal.

The mobile devices that support Qualcomm Quick Charge 2.0 will enjoy a 50% battery charge in under 30 minutes, which is lightning fast.

The power bank has two charging ports, one USB Type-C connection and one micro USB. 

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.
The 10,200mAh Fast Charge Battery Pack is a simple and stylish solution that works. The phone owners that have the support for Qualcomm Quick Charge 2.0 will probably appreciate this battery pack the most.
Bottom Line
One of the best powerbanks for smartphone use. If your mobile phone supports the Qualcomm QuickCharge feature - this power bank is a must.

10. Powerstation 8X – Best Slim Power Bank

The Powerstation 8X is the top of the line power bank that packs an incredible amount of power into one of the thinnest battery packs we have ever seen.

The build quality is amazing as the battery pack is made mostly of high-grade anodized aluminum.

The design makes it lightweight and you can easily slide it into your pocket or one of your bag compartments.

Apart from the looks and capacity, the Powerstation 8X is also a solid performer. The power bank is able to supply a quick charge at 15W (with compatible devices) and the Charge Vault technology allows the battery to hold a full charge for up to 500 cycles.

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.
The Powerstation 8X is quite innovative as it comes with a mobile app to monitor and manage the battery life of your power bank as well as your devices. It allows you to create notifications to help you manage your charge cycles effortlessly.

In our review, the Powerstation 8X came out quite comparable in terms of capacity and features with RAVPower 16750Mah. The biggest difference between the two is the shape of the power bank and the premium price tag the Powerstation 8X comes with.

Bottom Line
The Powerstation 8X is not cheap compared to the competition, yet you get a premium feel and slim design which could be well worth the extra money for some of us. Mophie products are featured in Apple's retail and online stores which is a great sign of trust.

11. RAVPower 16750mAh – Best For Charging Multiple Devices

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

It has highly efficient LG/Panasonic lithium-ion cells, great build quality and 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 a maximum output 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.
The device has a built-in iSmart technology, which automatically determines the charge rate most applicable to your device. 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 great. The best power bank in its size.

12. DBPower Q100 – Highest Capacity Power Bank

The 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!
The DBPower Q100 has two USB ports that are able to charge two smartphones at 5V/2.2A. On top of that, the power bank comes with an AC port, so that you can use your wall charger to charge your device. Although the DBPower Q100 has massive capacity, it is not the most efficient battery pack if you consider the performance to size ratio.
Bottom Line
If you are looking for the Juggernaut of power banks that performs well - you have just found one!

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 best power banks 2018 has to offer in various sizes, capacities and features.

 We thought that you may also be interested in the below buyer’s guides:

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 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.
