The Power2000 AC-LPE8 AC Adapter and DC Coupler Kit is a replacement for the Canon DR-E8 DC coupler and includes an AC adapter to enable continuous, direct power from an AC power source. This allows use of a camera for extended periods of time without draining the camera's battery. This AC adapter and DC coupler kit is compatible with the Canon EOS Rebel T2i, T3i and T4i DSLRs.
