You could either try to carry the ondio closer to your body so it does
not get that cold, or try to feed it some current via the usb-plug.
IIRC, the device cannot be charged from usb, but usb-file-access can
be done without batteries because the device takes power from usb.
I think others have done such hacks on the JBRv2: Get a spare
UsbMiniB-Plug (or rip one off from a spare cable), find out the two
extreme ends pins and feed it some 4-5 volts.
