 Q1:What are your power bank pcb assembly quality standard?

 A1:We manufacture power bank to meet IPC-A-610 Class 2 specification as the     .......
......default,supported by inspection and test .criteria established by IPC.

 Q2:Do you test the power bank before dispatch?

 A2:Yes,Every power bank pcb assembly should be tested before leaving the factory.

 Q3:How long is the guarantee period?

 A3:One year warranty, offer after-sales service!

 Q4:Are there any matters needing attention to use?

 A4:

 tDo not attempt to dismantle the power bank unit

 tDo not dispose of the power bank unit in fire

 tDo not store the product in places of high temperature

 tTurn off the power when not in use to avoid continuous power depletion.

 tKeep out of the reach of children.

 Q5:Are there power bank have any guarantees?

 A5:  

 tShort-circuit protection

 tOver-current protection

 tOver-charging protection

 tOver-discharge protection

 tOver-load protection

 Q6:Any matters needing attention for the installation?

 A6:The power bank pcb is connected to the battery negative B-, B + is the positive, do not connecting reversed, connecting            reversed will burn the board, the battery is connected in parallel welding, assembling battery. Note that the insulation                between the battery and the pcb board, battery lead not to touch the circuit board, so as not to cause a short circuit.
