grg Posted August 13, 2017 Share Posted August 13, 2017 I'm powering a few Orange Pi Zeros, so I don't have any choice but to use USB for power (well, more or less). So, I spent some time searching for the right power adapter. It has to be at least 2A and only have one plug (to keep people from plugging in their phones). I thought I found the right product and purchased 20 of them. I was having issues with not booting from the microSD card and was really lost as to why this problem kept popping up. Anyway, I thought to double check the power. I wasn't getting more than 700mA -- sometimes much less. And so, I decided to look deeper... 3 Link to comment Share on other sites More sharing options...
chwe Posted August 13, 2017 Share Posted August 13, 2017 Looks quite similare to the 'noname from aliexpress' used in my powering through micro USB thread. I get 1amp out of it but voltage drops to around 4.1V. Unfortunately, I never posted a picture of it. Edit: Opened it for you to compare... Not exactely the same...

grg Posted August 13, 2017 Author Share Posted August 13, 2017 Looks pretty similar. Perhaps it's just an updated version. Link to comment Share on other sites More sharing options...
