Testing of the usb charger circuit was conducted using a small solar panel and a car battery. The results are as follows.
For small solar panel, the phone charges normally without any problem.
When connected to car battery, phone keeps on changing from charging to discharging mode very often and does not charge at all.
What could cause such problem when connected to car battery? Can it be the current? What can i do to fix the problem?
Please help !
Thanks
