Review on Enhance Camera Power: CCYC DR-E8 DC Coupler for LP-E8 Battery Replacement, USB DC Converter Cable – Perfect for ACK-E8 AC Power Adapter, LPE8 Dummy Battery – Compatible with Canon EOS Rebel T2i, T3i, T4i, T5i, 600D, 700D, and More! by Loren Schmidt

Original I wanted to use this battery replacement for slow motion, but I also use it to extend live streams. Even with extra batteries, it still wasn't enough for a stream that regularly lasts more than an hour. At the moment this is the best solution. It's well built, fits the Canon T3i perfectly, and the USB port makes it easy and versatile in most situations. You can connect it directly to the computer and then to the camera and it will turn on, you can connect a USB power adapter or just plug it into the wall with a USB power converter. I am satisfied with the longevity of the power used. This is for interval photos. When it came to live streaming, everything worked without any problems. I've included a short video so you can see exactly how to connect it to your camera. Also included are photos of what it looks like out of the box. I hope this is helpful to you, if you have any questions I'm happy to help.
