Hi - I have a Paidashu 27000mah power bank which was damaged by a faulty usb cable. When I search for a new pcb I only find 18650 charging boards. Are these still compatible, even if the wrong size? I can't find an exact match for mine anywhere. Thanks in advance.

 

I think you are going to have problems matching the spec if you really believe that small power bank contains a 27 Ampere-Hour Li-Ion cell ! It's much more likely to be 2,700mAH.

 

Hi

It does appear to be 27000, I attach a photo with the batteries which are huge and on my other identical one charges several phones completely, by far and away the biggest capacity of any power bank I have.

 

If it really was 27,000mAH capacity, it would recharge about nine cellphones from one charge. Comparing the size of the two cells to the USB connectors, I would guess that the real maximum total capacity is around 8,000mAH.

 

Thanks, I'm not here to dispute I just would like to know if I can find the correct pcb please. TIA.

To do that you would need to know the real capacity of your power bank.

 

Hi, I have attached further photos, I have 2 batteries and a Google search suggests each is 10000mah. Does this seem realistic? Thanks

 

Can anyone advise or is this the wrong forum? Thanks

 

My advice would be to replace the power bank. These cells aren't very forgiving if you get things wrong.
