HobbyKing LIPO to USB Charging Adapter and Cell Checker

The HobbyKing LIPO to USB Charging Adapter and Cell Checker is a two-in-one device for anyone running Li-Po battery packs in their blasters. Plug in a Li-Po pack and it reads out the individual cell voltages so you can check the pack's health and balance before a game — catching a weak or sagging cell before it becomes a problem in the field.

Flip to its other function and the same unit becomes a USB charging adapter, letting you draw power from your Li-Po pack to top up a phone or other portable USB device. It's small and pocketable, so it's an easy addition to a battery bag alongside your chargers and spare packs, and it's currently part of our Weekly Deals.
