Conserve the battery power of your Panasonic LUMIX GH3, GH4, or GH5 Mirrorless MFT Digital Camera with the AC-BLF19E AC Adapter and DC Coupler Kit from Power2000. It replaces Panasonic's DMW-AC8 Adapter and DMW-DCC12 Coupler as an alternative to the camera's DMW-BLF19 battery pack, providing long-term, continuous power from a wall outlet. This capability is useful when shooting in the studio for hours at a clip, since you won't have to worry about your battery running out of juice. As the AC adapter runs on 100-240 VAC power, you can use it all over the world.
