I have a power-hungry pi device, and while most of the time it is okay, a surge in usage may result in insufficient power to the device causing it to reboot.
I have a RavPower USB power supply that I use in the car, which boasts 40W total output between two ports. My question is - and I know questions have been asked similar to this before, but I wasn't able to find the answers I needed - is can I use some sort of 'merge' cable (opposite of a Y-cable), to essentially merge the power from these two ports?
I would need to make sure it is wired in such a way that it provides 40W @ 5V, and not 40W at 10V of course, which either scenario would be possible depending on how it is wired (series/parallel). Would this be a viable option for supplying continuous power to my pi assuming that the voltage stays at 5VDC?
I have a few buck inverters lying around that I could adjust to deliver 5V/5A - but they do not have the comfort of circuitry to regulate voltage variance. I am not sure WHAT the variance would be, but I was unwilling to test it.
What are my options here?
