Sorry to bump an old thread, but I have had great success with the PWR+ brand 3.5 Amp power supply. This supply was made for those netbooks that used micro-USB for power so it's exceptionally high-powered with lower resistance. I use it for PINE A64 and Orange Pi/Raspberry Pi with fans and all kinds of bus-powered peripherals and never experience undervoltage warnings or SDCard corruption.
