Lanparte LP-E6 Camera Power Coupler DC Dummy Battery Pack for 5D3 5D2 7D 60D

Works amazing. I use it in my Canon 70d and Canon 5d mark ii. I connect this to the external usb battery and can shoot for hours. A cheaper alternative to buying expensive Canon batteries. I saved hundreds of dollars using this.Pros1. Long lasting if you plan on shooting for long period of time2. Value for your dollarCons1. Might get to bulky if your external battery is big2. Might be inconvenient for some people to be carrying a external battery around and shooting

Lanparte dummy batteries always do what they are supposed to. i this for my black magic video assist 4k moniter. works just fine.

When I took this out of the box to test, it worked fine. I went to use it in the field yesterday on a long time lapse sequence, and it didn't work. I tried different cables, different batteries, and nothing. I wouldn't recommend this.

Works just fine as it should. I'm glad the camera battery spot has a fitting for these kind of things

Have used this about a dozen times with a 5Dmk2 and 5Dmk3 and it works great

Very useful
