Andoer USB LP-E6 Dummy Battery for Canon EOS 5D Mark II III IV 6D Mark II 7D Mark II 5DS R 60D 60DA 7D 80D

Used on Canon 5D MK2, Ordered the "Upgraded" one instead. Fingers crossed

Tried on 5D Mk IV. Tried with a 4.8v batter pack and a 5V wall plug. Not strong enough. The camera did turn on but wasn't powerful enough to take a photo or video
