Output Charging:
Surprisingly there are two charging ports on this 4,000mAh power bank, or should we say, a 3,000mAh power bank that’s actually how much you’ll be using.
One of the charging ports has a charging speed of 5V/1.0A and the other charging ports have a charging speed of 5V/2.0A.
It’s best to use the 2 Amp charging port at all times and to use the 1 Amp charging ports only when you’re charging two devices at once. With that said, it’s very important to remember that charging 2 devices at once will split up the power capacity, and so if you’re charging two smartphones at once, both of them will mostly only charge about halfway through.
Input Charging:
The Kans power bank has a recharge speed of 5V/1.0A using a Micro-USB. As long as you’re using a 1 Amp wall charger or higher to recharge the power bank, it’ll be fully recharged within 3-4 hours.

Reliability
We think the Kans power bank is going to be most helpful for those that are always on-the-go and only expect one full charge from this power bank. This is because that’s the reliability that this power bank can offer with its power capacity and size.
This power bank is not going to charge a smartphone multiple times, or at least not most smartphones, and charging two devices at once just seems unnecessary.
