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. For one reason or another, the reality is that the battery storage development pace is not keeping up with other technologies. This is where a good power bank will help you bridge this gap, but which one is the best power bank 2018 has to offer?

We have to admit, that the amount of power banks available on the market today is simply astonishing. Making sense of all the options available is overwhelming, to say the least. There are literally hundreds of brands selling power banks, but which ones are actually worth your money? Let’s look into this a bit closer as we have done the legwork for you. We have shortlisted the 10 best power banks 2018 has to offer.

How do we test?

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 the 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 with different features.

1. Jackery Mini

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 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.

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. One of the best power banks 2018 has to offer in a small and portable segment.

2. Anker PowerCore Slim 5000

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. 

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. 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.

Overall, the PowerCore Slim 5000 is one of the best pocket power companions available in 2018. If you are someone who likes carrying the charger in your jeans whilst your phone is being charged – PowerCore Slim 5000 will get the job done for you.

3. Jackery Bolt 6000

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 and portability.

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.

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.

Overal, 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

Like most Belkin devices, the Mixit carries good design lines and solid build quality. The unit comes at a little 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 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.

Overall, the Mixit does the job well. It is a general purpose power bank with no premium features, but with a premium feel and build quality.

5. Zendure A2

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.

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.

Overal, in our opinion, 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

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.

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).

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 hickers!

Would like to see better performance when charging from the solar panel (e.g. Nomad 7)

7. Aukey PB-N50

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.

Overal, the PB-N50 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 a 1000mAh portable power bank 2018 has on offer – this is the best example available.

8. Anker PowerCore SPEED 10000

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. 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.

The Anker PowerCore 10000 is not a sophisticated power bank, but it does the job well. In fact, it is amongst the best sellers on Amazon with thousands of happy customers. We are convinced that given its price – you’d be hard-pressed to find a better alternative for the money. In fact, the only other viable alternative is Aukey PB-N50 (reviewed above) which we prefer slightly more due to having an additional USB port and a pocket-friendly design. Probably one of the best power bank 2018 has to offer in terms of simplicity, practicality and sheer value.

9. Samsung Fast Charge Battery Pack

The 10,200mAh 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 lightening fast.

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

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.

10. Mophie Powerstation 8X

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 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.

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.

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 from Apple.

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

11. RAVPower 16750mAh

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. 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.

With so many great features, RAVPower 16750Mah is worth the attention of any power demanding user. 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.

12. DBPower Q100

The DBPower Q100 is by far the largest portable energy storage we have reviewed. Due to its size and weight, the power bank is not for the general purpose, yet will be a very capable companion for some of us.

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 gadgets going.

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. Nevertheless, if you are looking for the Juggernaut of power banks – you have just found one!
