Sony USB Travel Charger and Battery Kit

The Sony ACCTRDCX is a battery and charger kit. Sony describes it as can be charged from PC, in-car, or via AC adaptor. It is a first-party Sony part, so it fits and behaves the way the camera expects rather than the way a third-party copy approximates.

It measures 1-13/32 x 2-3/4 x 1/2"' (36 x 70 x 13.5 mm), and weighs 0.56 oz (16g). Sony sells it as a matched accessory for the bodies and lenses named above; check that list against your own camera before ordering, because Sony changes mounts and shoe types between generations.
