USB Cable (5v to 12v)

This adapter lets you power your Bear Sentry from a USB port (by stepping up the 5V supply of a device, like a power bank, to 12V). Add a DC extension cable and you could power the fence from inside your tent where battery capacity may be less affected by cold weather. USB A to DC 5.5mm x 2.1 barrel plug, 27g / .06lb
