Hello everybody,
For a project I need to build a custom 5000mAh power bank with 2 USB (1A) ports and a microusb, 4 leds to indicate the battery level. I will need to make a small batch of these (100-200 units), hopefully without wasting too much money on it.
I have these options:
- buying a batch of powerbanks, taking them apart, and putting the pcb+battery in my custom casing.
(which I want to avoid)
- buying the pcb that already has 2 usb ports, 1 charging port, and 4 leds, and the battery separately and putting them together in my custom case
(sounds good)
- creating a new pcb for it
(which I want to avoid)
- any other ideas are welcome
I'd like to keep the cost under 10$ for the circuit board and battery if possible (if impossible, as close to that as possible).
I saw some power bank pcb/ic boards online for 1$, but all from unreliable sources, do you have any idea where I can buy quality circuits of this kind? maybe without the usb ports soldered on so I can place them in my case where I want them to be and just solder a small cable from the usb ports to the board?
Same thing goes for the battery, do you have any good sources of batteries?
Thanks a lot!
