Cubieboard2 Power Usage

Cubieboard power usage with SATA

I have installed lubuntu to my Cubieboard2 and I have also connected a 2.5” SATA HDD. I wanted to know if my power supply is providing enough power so I tried to measure current output from 5V power supply.

I used cheap small USB power meter (find also some on eBay for less then 5€).

My results varies according to HDD usage:
