What kind of warranty comes with this refurbished piece?
Hi there. We state our warranties at the bottom of the features. This has a 90-day warranty with ION.
What kind of power rating do the USB Ports have? Are they at least capable of 350mA? I am trying to avoid an extra wallwart power adapter if possible (for a Raspberry Pi Zero with a HiFiBerry board for an internet radio in my garage).
From the features tab on the main product page;
