This dummy battery allows you to operate your canon DSLR by plugging it into the wall. It's great if you are shooting video with your DSLR or if you do a ton of product shots and don't want to worry about changing batteries all the time.
This is not a canon brand dummy battery, but it worked fine with my old 5DSR. It does NOT work on newer mirrorless cameras.
Asking $15 or I will throw it in for free if you buy one of the lenses I have for sale in my other listings.
As with my other listings, I only accept cash in person.
