Raspberry Pi 3 Power Supply Issues.

[LarsH.]

i tested already 5 . I have now one with 2.8 amp an its working good. The current problem is that i want to run the pi with my battery (https://www.adafruit.com/products/328) and my power boost (https://www.adafruit.com/products/2465) but it seems like i dont get enough amp with that power boost

What is trying to draw so much power? It sounds like you have something plugged in that is eating up the current. You will either have to find the device that is wasting all that power or get a different power source that is capable of discharging at a higher rate to power it sufficiently. From what I've read of people's pi3 builds they seem to have overheating issues so that's something else to be careful of. Usb power doctor devices seem to be quite useful for checking current draw, maybe something worth getting in this instance.

I have nothing connected only, the battery and the PowerBoost 1000, but the pi dont boot, i found a charger with 2.8 amp thath work perfectly with out the rainbow box, the problem at the moment is the portable powering.

I finally get it to boot the PI ONLY with the battery, its seams like the pi don't need 5V (https://www.adafruit.com/products/328) to run, i connected the battery directly to the pi and it booted perfectly with only 3,7 V and 2,5 amp . now i need a solution to load the battery, but i am so happy hath its possible, i thought i wont boot anyway .
