The Stub Plug Adapter from STUB PLUG replaces the AC power cord on select chargers for camera battery packs. One end features the 2-prong IEC-60320-C7 connector that plugs into the charger itself, while the other end features the standard 2-prong NEMA 1-15P North American plug that goes into the power outlet. It requires no cord and has an extremely small form factor, with a length only a tiny bit greater than that of an ordinary 2-prong wall plug. This makes for easy storage and eliminates cable clutter completely. The adapter's right-angled shape allows the charger to lay flat against the wall while charging the battery. Depending on the design and shape of your charger, the Stub Plug can also be reversed for even neater storage in your bag.
