Hello all,
I was trying to power my RPi Zero from a LiPo battery using this module (http://www.ebay.com/itm/5x-5V-Step-Up-M ... 2278069095 and I have a problem. After I plug it in, the Pi starts booting, but after few seconds it shuts down. Can anyone please help me solve this problem? Thanks :!:

Let the battery fully charge maybe? Double check your soldering too. Any pictures?

The battery is charged to 3.8 V, so that shouldn't be a problem. Output is 5.1 V, which is also fine. I don't think there could be problem with connection between the battery and the module, because charging workes fine. The module is connected to the RPi via a USB cable. Couldn't there possibly be a problem, that the module can't outpout enough current to run the RPi?

i wouldnt just take the output rating as theyve stated....

theres a high change its not putting out anything near 1A

go for this one

it works perfectly with the pi zero (no head scratching)

Thank you.
Only problem is that this module is quite big, so I'm not sure if it's the best for my mintyPi project.

it can be done with your phone

Pretty cool app. Too bad it doesn't exist for iOS 😔

The module can provide only about 500 mA, so probably not enough. It seems like I will have to buy this one. Thank you for your help.

if your using it in the mintpi, then its best to use what wermy has recommended... he spent alot of time testing what options were best...

OK. And could the RPi work if I power it directly from the LiPo?
