Should power bank be charged full night for the first time?

Mostly, when we buy a phone, we would unconsciously ask that how long to charge the phone for the first time?

Likewise, when buy a power bank, we would ask ourselves the same question.

So, how long to charge power bank for the first time?

Same as the phone’s battery, the battery of power bank needs to be charged a bit longer before the first time using. 

Taking Heloideo’s power banks for example, they are all made of Li-Ion battery. Nothing complicated, when charging the power bank, we could refer to the built-in LED indicators.

Or Heloideo Dual USB Ports 11000mAh Power Bank, it has 4 LED indicators, thus each one is for 25% power on average. Is that full of charge when all 4 indicators are on?

When contacting with Heloideo power bank product managers and engineers, it’s not that kind of situation.

Actually, when 4 indicators are on, there’s only 95% power. Why?

—— First and foremost, that’s because different battery cells have different capacities, even in the same power bank, which is from the point of product design. And it aims to fully take advantage of the battery, which, maybe, will remind you when starting the car, you should preheat it.

—— Then, to some extent, it’s for better charging experience. As larger capacity battery for longer charging time, thus the former indicator will take more time to light up; the latter one or the last one will cost less time. So you will find the power bank seems to be charged up faster and faster.

Theoretically, most power banks will take 5% longer time for recharging up for the first time. But that actually does not matter. Free charging. Easy charging.
Surely, here is another factor, that is, the input. Normally, most power banks are allocated with one input in 1 amp. But if for 20000mAh power bank, it’s different. It will has two inputs and both of them are for 2 amps, enhancing the recharging speed up to 50%. (Monster 20,000mAh Power Bank Giveaway)

All in all, that’s case by case. Whatever charging problems you’v met, comment below, and we offer your solutions.
