A:Answer Yes
1) I bought four of the wireless (battery version). So far satisfied with performance (some glitchy stuff, but seems to be settling out) -- but mostly because I intended to connect them to the AC power to keep the batteries charged, relying on the batteries if should the AC go off. To do that, I called your help desk and asked, what is the specs for the barrel connector socket on the back (needed to select an AC to 5V DC wall adapter with the appropriate barrel connector). First they asserted it was impossible (recommended the wired one), then after I pointed out the solar panel has to plug in somewhere, they denied knowing anything about the specifications for the socket on the back. Totally oblivious and unhelpful
2) I got out my calipers and measured and confirmed the barrel connector socket on the back is 3.5 mm x 1.35 mm -- so I bought AC to 5V USB wall adapters and USB to barrel connector (3.5 mm x 1.35mm) cables on amazon and they're doing a fine job keeping the batteries charged up.
