Tired of buying batteries?
I'm all for anything that I don't have to buy batteries for every year.
non-standard phone connection
Nice package for the price except ... the phone charging connection. The world standard supply-side connection for phone charging cables is the USB Type A. Charging cables that connect to this interface abound. (That the phones themselves have yet to standardize is a separate problem). I want a charging device capable of connecting to whatever phone I bring to the party. That means USB Type A.
