Features to Consider Before Buying

We did some research and provided you with a list of some basic features you should keep in mind before picking your next power bank. While we consider those to be the most important, some of you may find out that you need to pay attention to different ones – and that’s fine as well, because ultimately, you’ll be the one using the device!


The capacity is the main specification you need to pay attention to. The battery capacity is measured in milliamp hours (mAh) both on your power bank and on your device.

Another important thing to look out for is the capacity on your device – so if a power bank has the same capacity as your smart device’s battery, it means you could use it for one full charge. When you look at power banks, it’d be good if you can get one that will allow you to get at least one and a half charges of your device.

The best way to calculate how many times you’d be able to charge your device is by dividing the capacity of the battery with the capacity of your device. If you own a smartphone with a battery of 1,400 mAh, you can charge it approximately twice with a power bank of 3,000 mAh.


Most of the time, larger devices require more energy – pick power banks with larger capacities if you’d like to charge tablets or laptops!


The input is the second thing you may want to pay attention to as it’s directly related to the charging time. If you’ve had a power bank before, you’ve probably noticed how your phone charges much slower when plugged into it – and that’s exactly because of the input!

A phone may support a higher input current but your power bank may not have the exact same output capacity for it. Try getting a power bank that allows you to charge your device at more or less the same time you’d normally would.


A power bank should be portable – you will carry it around quite often, won’t you? However, sometimes portability comes with a price to pay, as thinner and lighter power banks usually have less capacity in them.

A power bank that’s both light and with a larger capacity may be a bit pricier. But if having more space in your backpack means more to you, then by all means go and do the investment. If you’re looking for a regular power bank, then it’d be ideal to compromise a bit on the portability in favor of capacity.

Safety Technology

Many buyers will find the safety features of the power bank important. Modern power banks should have at least some sort of a safety technology implemented in that should prevent your device getting damaged during charging time. These include but are not limited to overheating resistance, overcharging prevention and so on.

Apart from that, check to see whether the power bank you’ve chosen features an integrated circuit or not. The integrated circuit allows your battery pack to automatically detect the sort of the device you’re plugging in and then charges it at a maximum capacity.

After Sales Service

Most power banks come with warranties but don’t forget to check whether yours has one or not. On top of that, most sellers offer after sales support and assistance as well.

Best Products on Today’s Market

After reviewing the features to pay attention to before making a purchase, let’s see some of the top products we found and their most important specifications.

Jackery Mini Premium 3350 mAh Portable Charger Jackery Mini Premium 3350 mAh Portable Charger 

Price: Approx. $17

Weight: 2.8 oz.

Dimensions: 7 x 0.9 x 0.8 in

Specific features: Portable, LED indicator, comes in a variety of colors, extended warranty included

Best use: Everyday use, short day trips

Description: The best feature of the Jackery Mini Premium 3350mAh Portable Charger is that it’s so small, it can be even carried in your pocket! In regard to its capacity, the power bank comes with 3,350 mAh and can be used to fully charge your mobile phone once.

This model should be compatible with most of the brands that are in use nowadays. However, some users may not be able to use the charging cable that is included, so you’d have to use the one that came with your phone.

Another thing you should note is that the charger features a rather unusual on/off button that needs to be switched on every time you want to plug in your device. The device won’t start charging your phone till you turn it on using the power button. However, the on/off button is helpful because if you don’t plug any device after you turn it on, it’ll automatically shut off, thus saving you valuable energy.

The product comes in a variety of different colors and has a warranty included with it. This power bank is a good pick if you’re looking for something cheap and easy to carry along.


  • Light and easy to carry around
  • On/Off button for extra safety
  • Warranty included


  • You’ll probably be able to get only one charge out of it
  • Some users may prefer something with higher charging speed

Best use: Traveling, camping

Description: The EasyAcc 10,000mAh Power Bank is said to be compatible with almost every brand on the market out there. The main advantage is that it can be used to charge more than one device at a time. You could either charge two phones or one tablet at a time and you’re likely to be able to charge your device 2 to 3 times before the charger runs out of power.

It is also said to charge devices quite fast except for when it’s plugged into a power source for recharge, so that is something to note.

Among the cons, it’s said that this product maybe a bit heavier than other portable chargers but it’s not intended to be a mini charger. It has a higher capacity and the weight could probably be justified by that.

A few customers who have purchased the product have mentioned that the product stops holding a charge after a while and that it doesn’t work so well after the warranty has expired. You may want to contact the manufacturer and get more info about its warranty and the terms and conditions related to it before making the buy.


  • You can charge two devices at once
  • Pretty decent capacity
  • Great value for your money


  • Product may be bigger than what you’d want out of a power bank

Specific features: Lightweight, allows high-speed charging, comes in a variety of different colors, warranty included

Description: The major advantage of Anker PowerCore+ mini 3,350mAh Portable Charger is that it’s very small and can even fit into your pocket. It can charge your mobile up to 100% once with a little power left after that. You also need to turn the power on for the device to start charging your mobile so that’s something you need to remember.

Another good feature is that it is compatible with all kinds of apple and android smartphones that we use today. The power bank also comes with a micro USB cable and a travel pouch.

A few buyers have stated that the device stops working after a while and that the quality may be poor since you are able to get it at a low price. Other customers, however, have suggested you contact the customer support if you face any issues and that the company will offer you a replacement product if you are under warranty.

In short, this could be a good pick if you are looking for something lightweight and just want to quickly charge your device once a day.

Though the product comes with a USB cable, most buyers have recommended you use your device’s original cable as the one that’s provided may not be compatible. The LED lights blink when the device is charging and when the lights stay lit, it means the battery is full.

Even though the product is said to have a long life, some buyers have mentioned that the device stopped working after 6 months of use. It’s also said to be a little bulky as you would understand from its weight.

This product could be useful if you are someone who carries more than one smart device and needs to charge them often. If you just want to charge your mobile phone during the day, you could probably look for a something smaller because this might be too much.

It is also said to be very convenient because it charges your devices to a considerable amount even with the very little power to spare. The indicators also quite accurately display the power that is left in the charger.

Some may find the device to be quite heavy and large, which makes it a bit difficult to carry. However, considering its capacity, it may as well be worth it.

Even though it features two USB ports, you could start experiencing troubles with the ports after a while – if that happens, just the seller’s customer support and request for a replacement, as that may be a manufacturing defect.

To sum it all up, this is a decent purchase for owners of multiple devices that need to be charged often. Optionally, you could also take it with you on longer trips or while camping.


  • Larger capacity that allows multiple charges
  • 2 USB ports for simultaneous charging

This power bank is again convenient for longer trips, as it may be a bit too bulky for everyday use.

Considering its capacity, you shouldn’t be disappointed if you’re looking for a power bank that allows you to get multiple charges.

Considering its price and capacity, it’s a pretty decent buy. If you are looking for something that can hold a good amount of power, charges more than one device at a time and does the job quickly, this could be a good choice.

As far as the capacity is concerned, it should take approximately two and a half hours to charge your device from 0% to 100%, which can be seen as considerably fast. The LED lights display the amount of power that is left in the device. However, the capacity is not its biggest perk, as it allows for one – or a maximum one and a half – charging cycles.

Also, if you are looking for something that has a very long life, then this may not be a good pick as experience has shown that durability is not this product’s biggest perk. But on the other hand, you get some warranty as well, meaning that you should be covered even if the device malfunctions.

The device is ideal for someone who doesn’t use up a lot of battery life but still needs a power boost in the middle of the day – it’ll keep you going until you get back home. Considering its price, it can be seen as a product with a decent quality.


  • Lightweight and small
  • Fast charging speed
  • Includes a limited warranty


  • Allows for only one charge
  • May not be the most durable product out there
