Using Lipo Charger to directly power android tablet
My android tablet suddenly died on me and refuses to power up. Unable to charge the battery as well.
Am thinking of removing the battery from the tablet and then hooking up a lipo charger to the black and red wires on the circuit board. Hopefully this can power it on directly without the battery.
This is a simple and inexpensive lipo charger I'm looking at:
Few concerns that I have:
- Can the lipo charger be used as a direct power supply? I know voltage-wise, it's safe (3.7V). But I'm not sure if circuitry-wise, a charger works the same way as a power supply
- Is 500mA current output from the charger enough to power on the tablet? If not, what is the recommended current output?
- How do I know if the tablet has any logic to detect the presence of a battery? From what I see on the circuit board, there are only 2 black+red connectors (no data connector or anything)
Es esta una buena pregunta?
