How to choose a power bank?

While you can always plug your phone to a wall socket and charge it, it becomes quite cumbersome when you need to move around a lot. This is why you should invest in a good power bank charger that can help you easily keep your battery full at all times.

A power bank is essentially a portable charger that you can carry with you anywhere you go and plug into your phone or tablet to charge, whether you are at home, in the car or out travelling. There are many options available in the market, but before you pick one consider a few points first.

1. Capacity

The main feature most important to charging will be the capacity of the power bank. This is calculated in mAH or milli Ampere Hour. You can’t accurately gauge how many times a certain power bank will charge your phone, but generally more the mAH means more the capacity. So for instance, if your phone has a 1500 mAH battery, a power bank with the same mAH should completely charge it once.

2. USB port

You need to make sure that the power bank is compatible with your phone’s charging port. As many different models are available, you may be able to find a certain power bank designed specially for your phone or tablet model. Incase this is not an option, you can also get a cable that will easily attach the two.

3. Price

There will be many price ranges for you to choose from but don’t be fooled by low price products as they may be harmful for the phone. Such low price power banks may contain low quality or refurbished batteries and can short circuit and damage your phone.

4. Portability

The whole point of using a power bank is due to the fact hat you can charge your phone on the go. So, make sure you pick a power bank that will be easy for you to carry around with you and is not too intrusive and cumbersome.  

Here are some good options for you to choose from:
