Guide of Buying exmight Power Banks

Let’s be honest, we all love our phones and tablets. One day, perhaps, we may leave home without our wallets but we most certainly won’t leave without our phones/laptops/tablets on us.

And this ‘love for gadgets’ comes with only one major fear…that of running out of battery! Oh my God!! Haven’t we all been there before…the 5% remaining red line that drives us into a tizzy!

Power Bank

But, by the grace of technology, we have at our disposal the Power Bank. A power bank is basically a secondary battery, on-the-go, something you can plug your device into & charge ASAP.

Here are 5 tips that we hope come in handy, while choosing a power bank.

Power Bank Output Current

Output

Most power banks use a 5V or 1A (ampere) current to charge your devices. While this works well for cellphones, the rule doesn’t necessarily apply to all gadgets. Some android tablets need a 2A current for a complete charge, while others like the iPad require 2.5A. For instance, if you try charging an iPad with a power bank, which gives a current output of 1A, either your iPad won’t charge at all, or it would take forever to charge.

Hence, you need to first decide on why you are buying a power bank. If it’s only to charge your phone, a 1A/5V current should be fine, but if you generally need to charge other devices on-the-go as well, then your decision must vary accordingly.

Also to clarify here, it isn’t necessary that a battery that lasts longer will charge faster. Charging is influenced by the capacity of the power bank. A higher mAh will charge your phone faster, and conserve the power bank charge as well.

Ports

The latest power banks come aided with a USB cable, which completely eliminates the task of having to carry around extra cords or searching for a charging point.power bank factory

Also, the number of ports in a bank, is another important feature to consider when choosing a power bank. There are power banks with one/two or even three ports, so it really boils down to how many devices you carry on-the-go which will need charging. To make it relatively easy for you to choose the number of ports required, here’s the math behind it.

Let’s assume your bank has 2 ports. Provided your power bank has an output current of 3A, only 1 device will get completely charged whereas the other device so connected will receive an output current of only 2A. This means, that the current being received by each device will be an average 2.5A implying that neither device will get fully charged.

Portability

When it comes to portability, capacity and portability of a power bank, are like two sides of the same coin. One with low capacity will be smaller and give you increased portability. For instance, a 2000-3000 mAh will fit in your palm whereas a 15000 mAh will be large enough to not fit in your palm or pocket! And of course, vice versa.

Price

Neither is every low-priced power bank bad, nor is every expensive one worth the money. Check for the above features before you go ahead and buy the right one. Some, inspite of a good output current maybe cheap, while others may lack good output current but still be costly, only because they’re a ‘brand’. Therefore, in order to not get fleeced, have your purpose of buying the power bank very clear in your mind.

Over – Charging

A note of caution – never charge your devices with a power bank, and charge the power bank at the same time. Although this might charge all your devices quickly, it wouldn’t be a safe option as the current over-load may cause your wires to burn and also lead to short-circuits sometimes.

Besides all these features, some power banks also come in an array of vivid colours, LED indicators and an inbuilt torch.  Lastly, remember, Shop Smart, Live Smart.
