Best Portable Charger Buying Guide

When investing in a good quality power bank, it is vital to keep the following considerations in mind:

Power and Capacity

External battery packs not only come in various sizes and shapes but are also equipped with different capabilities. You can find a charger with 2,000 mAh and as well as one with more than 2,000 mAh. Before choosing the best portable charger, it is essential to keep in mind the devices you plan to charge with this device.

Are you going to charge different devices simultaneously? How long will you be away from your wall charger? Answers to these essential questions will help you decide what should be the energy capacity of your portable charger. For example, an iPhone X is powered by a 2,716 mAh, while a battery with 3,000 mAh is needed to power a Samsung Galaxy S8.

Once you know the capacity of your device, you can choose a charger accordingly. A small charger with 3,000 mAh will be enough for charging most smartphones. However, you will need a charger with a capacity of more than 10,000 if you want to charge a tablet or a laptop.

Also, if you are going to charge multiple devices simultaneously, you will need a charger that supports two USB ports. Similarly, if you are away from your regular charger for longer periods or will need to recharge your devices more than once, you will need a charger with high capacity.

Charging Time

Charging your device with a portable charger and charging your battery pack are two different things. You can leave your battery pack plugged in all night to charge. However, it is better to choose a device that takes little time to charge your phone.


If you are going to charge multiple devices, your charger should have extra ports. Some chargers come with additional features like LED indicators and flashlights that come in quite handy. Such models are more helpful if you travel a lot.

Size and Weight

Another important consideration when buying a portable charger is its physical size and weight. If you are carrying this unit around the whole day, you will want a lightweight model. Typically, chargers with a small battery and one or two output ports are significantly smaller in size.

portable chargers

On the other hand, chargers with large batteries are very hard to carry in your bag or pocket. In conclusion, if you commute a lot on foot, then a smaller charger would be a better option.


It is important to invest in a portable charger made with high quality materials. Aluminum chargers not only look and feel good; they are more durable. Even if you accidentally drop it, it remains safe. On the other hand, plastic chargers are lighter and cheaper.


After reviewing the above products, we find the HyperGear Dual Input Portable Charger to be the best product available.

With 26800mAh, this is a beast of a charger that provides multiple charges to your devices for days with just a single charge. Moreover, its digital LED display clearly shows the amount of battery left in the charger.

Battery life is a consistent issue with smartphones. And it can be quiet annoying to be tethered to a wall at all times. Therefore, having the best portable phone charger is vital to keep your smartphone up and running without facing any difficulty.

Reading online reviews and learning from user experiences is a great way to ensure that you will choose a reliable and durable product. Make sure you read the above reviews before choosing the best portable charger that suits your requirements.
