This AC Power Supply with?Canon LP-E6?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. The power cable runs 8 ft long so you’ll have enough length to move around. 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. Made in the USA.
