TAPP Lite draws 8mA (.008A) which isn't much so unless your bike sits for a long time, it won't drain the battery.
TAPP 2.1A with its MOSFET switcher draws a whopping 35mA and will kick the snot out of all but the biggest touring bike batteries in a few days. We recommend connecting the TAPP 2.1A family of USB power ports to a switched circuit like an accessory or taillight circuit. We provide one of those triple-trick PosiTaps to make the connection very easy.
Hope this helps.
Sure does, thanks!
Great product, I own 4 of them, but I had 2 dead batteries and had to ask...
Will re-wire them to switched hot wires, much grass!
