Every new year mobile phones are taking birth with a high pace. It’s a result of the innovations in the field of technology. But, then the only thing we lack in is in the improvement of its battery life. The battery life does not seem to get better. To keep your smartphones/tabs/or USB devices stay alive all day long, you need a power bank. They’re available in all shapes, weights, and capacities. The five essential points are as follows:
Some power banks are small and light in weight to easily slip into our pockets. Some of them just slung in a bag. Consider their weight and try to avoid large designs only if you’re going to carry it every day.
Always be aware that a power bank will never deliver it’s full rated capacity to your device. The energy is lost due to the generation of heat and voltage conversions. Some of them are expected to achieve only about 70% of efficiency. In such cases, a conventional 10,000 mAh power bank will deliver only 7000 mAh of power whereas the best one may offer about 90% efficiency. So it’s important to check your gadgets’ battery specification to estimate how many times you can get your device charged fully.
3. Charging and Recharging:
When it comes to recharging the PB, the higher the input rating, more quickly it gets loaded. For instance, a 1Amp input will give an output of 5W (5V for USB), and a 2Amp input will provide an output of 10W.
Not all brands but a few of them provide you with a USB charger in the box. If you don’t get one, you can use the USB that you got with your phone/tab. Note that, a PB device with a 2A (10W) input will not recharge its battery faster than the one with a 1A (5W) information when used with an underspecified USB charger and vice-versa.
4. Additional features:
The best power banks support auto-on and -off mode functionality whereas some support only auto-on mode.
A power button on their casing is typically used to light up the LED flashlight (if the power bank has one) and a separate series of LED light that indicates how much capacity is remaining. Go for the one with LCD that tells you exact remaining capacity, so that you never get caught short anytime, anywhere.
When it comes to price, it is not at all a barrier because the best power banks with useful features are surely going to be costly when compared to a regular power bank. It solely depends upon the devices that you’re going to charge through your ability bank and buy a perfect one suitable for it.
