This battery has worked wonders for me and a great value for the money. While it works perfectly for my purposes, the battery drains a little faster than I expected but I'm not sure if my expectations are aligned with reality or not. But either way, it lasts a LONG time which makes how quickly it charges an even bigger plus. If I had a need to, I would buy another in a heartbeat.

So convenient!!! I use this for multiple parts of my studio set-up when needed. It takes a little time to charge up to 100% but it holds that battery life a long time! It's heavy, so if you're using it for a part of the camera, I suggest an attachment piece for it. Love this battery, though. Worth it if you're considering it.

SmallRig has nailed it with these batteries. Hoping the cells last for a long time.

If you’re looking to add extra weight and stability to your video rig, this V Mount Battery is a solid choice. I originally used this for my A7 III, using a cable from the battery’s USB A port, into the camera’s USB C port.Once I upgraded my A7 III to an A7S III, I quickly learned that the USB A port’s power was insufficient. Switching to the USB C port was all I needed to do. Now this battery has no issues powering the A7S III while shooting for hours.

Great battery in a small package. It powers a camera but half the time the family 'borrows' it to charge all their devices

If you're on the fence, just buy it. I was hesitant to move over to a V-Mount system for the longest time. But man, these things changed my relationship to professional shoots. Over quick charge USB-C, it charges up increibly fast. On big shoot days, I can bring one of these guys fully charged, and never have to worry about battery life. The screen on the back helps a ton, especially when charging or trying to gauge how much battery life you have left. The build quality is sturdy and the look itself is sleek and unassuming. Super easy to use with a TON of ports for powering multiple devices at once. At full price, I still think these are absolutely worth it. But they're also on sale very often. Highly recommend

Don't let the capacity of this fool you. It's a monster. I have so many cheap battery packs that are "10,000 MaH" yet are usually near dead after charging a phone. I used this with an arm mount to attach and charge my gimbal when it gets low so I don't have to stop using it, and I haven't charged either in about a month. (aside from charging the gimbal with this) when I take about 50% battery from the gimbal throughout a full day of use about 4-5x a week.

This battery is a powerhouse! Compact design with plenty of mounting options. It keeps my camera, monitor, and other accessories running smoothly for hours. The digital readout is a nice touch, very convenient to monitor battery levels.
