How to Choose a Power Bank?
When faced with so many brilliant options, deciding what power bank to buy can be quite an ordeal. However, the power bank market has a lot to offer if you know what you’re looking at and what you’re looking for.
Here’s what you must consider to make an informed choice and purchase only the best power banks for your mobile devices.
Not even the best power banks are 100% efficient. The standard power efficiency for battery banks is about 60%-70%. However, some do deliver up to 90% of the battery juice. Look or test for the power efficiency before making the purchase.
It’s better to invest in the more advanced powerbanks that support Quick Charge3.0 and USB-C standards if your smartphones too are acquainted with aforementioned tech.
Power IQ or other similar technologies ensure safety as well as fast charging simultaneously.
Auto-on and auto-off is another extremely valuable feature of power banks.
Pass-through charging is a sought after feature in power banks, which usually works by prioritizing the connected device and directing only the spare power to the battery bank.
Design of the Unit
Design and a sturdy, compact build is a major player when purchasing a power bank. Always opt for the smallest unit at the same capacity.
There are power banks that come with water proof, shock-resistant, and matte finish outer casings. These are more durable and heavy-duty options than others in the market.
Typically, nearly all power banks come with 4 LED battery status indicators. However, if you wish to get the exact readout of the remaining battery, pick one with a built-in LCD screen.
LED torch/flashlight is increasingly being added to power banks. It can come in handy in certain situations, such as camping.
Input and Output Power Rating
The input rating on the power bank determines how fast it charges therefore you’d want one with the higher Amps.
If a power bank has multiple outputs then the maximum total output determines how fast and efficiently each USB port delivers.
We all want to extend our smartphones’ battery life to the maximum possible and power banks are as close as it gets to this rather unreal aspiration. Before heading out shopping for power banks, ask yourself what do you need most of all the features mentioned above and make the choice accordingly.
