Q:Will your company falsely advertised capacity ?

A: The answer is no. We only provide the true capacity, even though it looks like that our products are more expensive than the other suppliers. You are more than welcome to visit us and we will show you the test machine we have been using to strictly test the true capacity for each products. You could also test on your own.

Q:Are capacity factor and efficiency the same? 

A: No. Efficiency is a measure of how much the power bank is converted to electrical energy. It is unavoidable that some energy is lost in the conversion process. Even when the power bank is generating power at its maximum capacity, it is around 85%, which is usually reached before generating at full capacity. Capacity factor is a measure of actual output of a Power bank, which varies with the electronic devices you are using, it could ranges from 65% to 85%.

Also the unit does not come with its own wall adapter. You can either charge it with the USB port on a computer or use the USB wall adapter that came with your other devices.

Q:How can I tell when the Power Bank is fully charged?

A: Let it charge till the light stays solid and stop blinking. However, because of the minor electric current, the last LED indicator can not stop blinking even though it was fully charged. Please refer to our charging time, if the first 2 or 3 indicator stayed solid and the charging time’s up, we could tell that it was fully charged.

Q:Are your power bank able to charge two USB devices simultaneously?

A:Well, it depends. When comes to dual connector Universal Power bank, there is no problem to charge two smart phones. It is possible for the Power Bank to charge one mobile phone and one tablets if the combined rated power current could meet both the mobile phone and one tablets. For example, if the combined rated power current for the power bank is 1A + 2.1A = 3.1A, and the rated power of mobile phone plus the tablet is under 3.1A, it is compatible for both of them. If not, then it would not work.
