This Bescor DRE6K AC Power Supply with a Dummy Battery lets you conveniently power most cameras that use Canon LP-E6 batteries directly from a wall outlet, allowing for continuous power at an event or in the studio.
On one end this handy power supply features an LP-E6-type dummy battery, and the other end has a standard US power plug. At the same time it supports worldwide 100-240V power input (using optional plug adapters). Some cameras may not be compatible because the battery doors may not support proper dummy battery use.
Canon EOS 5D Mark II, 7D, 60D, 80D & R DSLRs
