ACK-E15 AC Power Adapter Supply Kit for Canon EOS Rebel SL1 / 100D DSLR Cameras

I was at first disappointed because the power adapter introduced a buzz into the sound of videos shot with this device connected. However, I discovered after some experimentation that the cable for my external microphone was too long to use with this adapter. It had worked fine under battery power, but combined with the ac connection there was a problem. When I switched from a 10 foot cable to a four foot cable the noise disappeared. It is great to be able to film long sessions with ac power as the battery invariably died when it was most inconvenient to stop and switch batteries.

Works perfectly in my Canon Rebel SL1 to avoid using a battery. I've been using it for a full month, including overnight time lapse, with no issues. I'm not sure if something that does exactly what it says it will should be 4 or 5 stars and I don't know if there might be an issue in the future but I'm giving it 5.

I've only had this a few days, and nothing bad has happened. That's about all you need to know, right?So far, the camera stays powered up, with it's usual timeout for inactivity. My only gripe is that the battery indicator shows half power. I have yet to see if that has any negative implications.I'll update if anything changes.UPDATE (11/2/18): I've been running the camera 2-4 hours at a time, 4 days a week, and no issues.

Saving me a bundle on batteries. Works as advertised. After an hour or so the camera does start to heat up but it hasn't been an issue so far.

I bought this last year to use it with my camera as a Webcam since I have been teaching from home. The camera would run 4-6 hours with no problems.It worked without issues until last week when it just stopped working. There was no warning that something went wrong. It was working one day and the next it wasn't. The light on the converter box is off. I'm buying another one because I need it. I think it did what it needed to do and the price was fair (I think it was around 15 dollars at the time). I hope the new one doesn't crap out as well.

I used this for client events, so I know preciesly how long it lasted. It worked for six and a half hours, and then started causing power failures. It is not usable.

Works fine and total length of line is a little over six feet

I use this to record at events using my Canon Rebel t3i - works great. Cord isn't that long so I use an extension cord with my tripod set-up.
