Hopefully someone may be able to provide some much needed knowledge on this.
I noticed when plugging in another device to the spare USB port that the PI immediately rebooted. Presumably the device requested a charge which overloaded the power supply, with only 5V available this now seems fairly obvious.
Ideally I wanted to be able to occasionally charge a small tablet from the HestiaPI without having to run from an additional outlet. It wouldn’t even need to draw much power logically, but unfortunately I can’t really control that. Presumably I would need to replace the power supply with something more capable, but would that be likely to solve the problem and would other precautions need to be made in regulating the power?
