The 10 Best Power Banks 2018 Reviewed

If you’re living in 2018, you’re probably living the smart life. You probably spend a lot of time on your smartphone, your laptop, or any other mobile device. And if so, you probably understand the importance and the need for a power bank. It becomes essential to have backup because if your device runs out of juice, you’re stranded. But, given so many choices, it might be overwhelming. There are so many competing brands and products, but how do you know which one is worth your money? We are here to help.

Before buying a power bank, there are a few things that you should consider. We did the legwork in this article for you, but you should be aware of what things to look for before you hand out your money. Firstly, you should check for the mAh capacity of your phone (or any other device you intend to use the power bank with), and purchase only those power banks with mAh capacities higher than that. If your phone has a battery capacity of 2000 mAh, and you purchase a power bank of capacity 6000 mAh, you will be able to charge your phone thrice. Also, look at the type of cells in the power bank. There are two types – Lithium-ion and Lithium-polymer. The former is cheaper but the latter hold more charge.

Things to consider before making a purchase

As is the case with any other product, there are a few things that one should consider before making the purchase, depending on their specific needs and expectations.

  1. What is the optimal capacity for your needs?

    This one depends on a few things – the number of devices you intend to charge with the power bank and their battery capacities. For example if you carry a tablet with a 5000 mAh battery and a smartphone with a 2500 mAh battery, then the power bank you purchase should be at least 8000 mAh so that you can charge both these devices at least once.

  2. Do any of your devices support Qualcomm Quick Charge?

    You can look up your devices’ manuals for this, and if they do indeed support Qualcomm Quick Charge, you should invest a little more money and buy a power bank with support for that so that you can charge that device faster.

  3. How do you intend to carry it?

    If you intend to carry the power bank in a backpack, weight should not be an issue for you and you can go ahead and get the heaviest one. But if you wish to carry it in your pocket or handbag, then you should look for the lighter ones.

  4. Does the power bank come with cables?

    You must check if the power bank comes with cables because if it does not, you must make sure you have the cable, or purchase the required one separately.

Conclusion

There is a plethora of choices out there and depending on your needs, you must buy the one that makes the most sense for you, following the things to consider given above. We did the legwork for you and made a comprehensive list of the products you can look at. All in all, you should get a power bank which has sufficient capacity while not sacrificing portability (if that is important to you) and which allows you to charge your devices fast and safely.
