    would be better to use a forward biased silicon diode (voltage drop =~.7 volts) leaving 5,3 volts nominally in the usb specs for any battery of a higher voltage i.e. nine volt a regulator is needed
    careful some regulators drop excess voltage as heat wasting valuable watts

    NO, not only in America both companies are American therefore would not break copyright laws, the energizer bunny is a trademark, the problem lies with lowlife foreign companies who steal american intellectual properties. counterfeit batteries are a well known problem in lesser countries.
