Just some general comment, Can you add some more properties here to
know voltage and current?
Also, can you add other properties present in charging status register
like POWER_FAIL, VOLTAGE_OR,
CURRENT_OR etc.

Don't know weather it is feasible to add or not and Also, let me know,
if it is already been covered in
some part of the code.

Thanks
