My Cubieboard2 and Cubietruck have been online for almost as long
as I've been doing sunxi work, which is a bit more than 2 years IIRC.
I've switched power supplies in between though. The PSU that came with
the Cubieboard2 is probably a better one, as it outputs right around 5V.
Others I've had either only give 4.8 ~ 4.9V, or way higher than 5V. This
causes problems with SATA on the Cubies. The step-up converter on the
Cubietruck doesn't like higher voltages, giving off weird noises.
The PSU I currently use is the Anker 60W 10-port USB charger:

Last time I checked the output is around 5.1V but it works well for all
my boards.
