Hi - a question about the electronics, do you have 1 series of 4 parallel cells, with 3.7V nominal voltage?


Something is not good with the design. I have printed out, and found that the case isnot taking into account the little black thing wired with coil, so it can not close it. And the coer is wrong too, because the screen is on the lower part. And the On/OFF button is hidden too...so it needs some fixing.
I was using this:

Thank for the message.
I think your model of power bank is a little bit different by mine.
I fix it.

Thank You :-)

You are right. If you just compare the two picture, mine has under the scree all electronics. SOrry!
