[7.6 x 7 x 1.45"] Allows me to hook up to an external battery so I can capture the upcoming solar eclipse from beginning to end. Great product, wish I had it sooner.

[0.54 lb] I've just purchased a second Case Relay system as it is so good. I highly recommend this system as a rock solid way of powerering cameras for endless hours. I've recorded non stop 4K 100Mbps on my GH5 for over 10 hours and including in over 30 degrees C heat, and this system works perfectly. I've done this dozens of times and it always works. The camera sometimes shows full battery and sometimes shows 2 of 3 bars but never below that. I've used several power banks and two different phone chargers to power it, and hot swapping worked perfectly. Only one small cheap power bank refused to power it, but I wasn't surprised or disappointed. In between shoots I will sometimes power up the camera for a few minutes without providing a power source, and the internal battery in the Case Relay copes with the load and it doesn't lead to any bad consequences during the next day of shooting. If you do time lapse or long videos or just don't want the hassle of switching out batteries, I highly recommend this amazing gadget!

[Lithium] Bought it and tested it over a week, works well. Overall good purchase.

[0.54 lb] 07/30/2020 - 1 month of ownership - heavy use for timelapse. Never gets hot, provides continuous power, and doesn’t add to the bulk of my gear bag. This power solution is lightweight and trustworthy. The price point will be determined by years of use, and I plan to update my review to reflect this products durability. Here’s a tip...

Use a quality external battery source. I use Goal Zero. Cheap “power banks” you buy from a grocery store may not provide enough continuous power. I know this from experience and it goofed up a 6 hour TL.

[8 VDC, 2 A] I bought this to use for powering long duration time lapses in remote locations. I have several external batteries that have USB outputs that will power the Case for overnight or longer duration time lapses.
