I May 2019 I tried one of these (Uooc? Reytric?) V-mount batteries - 16 months later it's still going strong, but it's a big 190wh brick; I wanted to test some other sizes. This 95wh seemed like a good value, as it includes a D-tap charger. I also like the 4-bar remaining power display on these.My uses for v-mounts are LED lighting for video and stills; for my big key panels I use the large 190 bricks. I've wanted some smaller batteries, and I tested this on a Came Boltzen 60 watt Fresnel. My testing is as follows: I attach the battery and run it down to one bar (it showed 4 bars - fully charged - when it arrived). Then I give the battery a full charge, attach it to the light and time how long it takes to run down to one bar. (I don't run the batteries til they die completely, since my understanding is it's not good for li-ion batteries).This 95wh battery took about 70 minutes to reach one bar, which is great performance. I decided to take a chance and see if it could reach 90 minutes - and it did, the 60-watt LED still blazing away when I shut it down. I consider that to be excellent performance, and it's rare for me to run longer than 90 minutes for corporate interviews, making this an excellent addition to my lighting kit. I've looked at shoot-out reviews of the top-line battery manufacturers, and 90 mins. from an 80-90wh battery is top of the line performance - and those tests were with a 48w draw. 90 minutes pulling 60 watts is truly excellent performance. The battery remained at room temp the entire test, and doesn't get hot when charging, a sign of solid engineering. Out of curiosity, I attached this to my big Lightstorm LS-1S panel - it powered the Lightstorm at 100%, reaching 1 bar after about 28 minutes. Again, that's impressive - most batteries under 150wh can't even reach 100% power on the Lightstorm.I can't stress this enough though - if you're looking to power a camera and monitor, you should expect long working times from this battery - 60 watts is a really significant draw, and even a fully rigged out, Hollywood-level cinema camera isn't likely to pull that hard.Another issue with some of these new manufacturers is wonky v-mount locks; read Amazon reviews and you'll find mounts that are too loose, too tight, wobbly, or take some pounding to attach. This battery attaches and unlocks as smoothly as any big-name battery, physically it's a solid-feeling professional product.My 195wh batteries from this manufacturer are going strong after 16 months (often working outdoors in 100+° weather) so I expect this to be a great overall value. In addition to the D-tap charger this battery ships with, the construction seems solid (you also get a USB port, making these priceless when the power goes out). V-mount prices have dropped in the last year, and this battery isn't the lowest-price out there, but is a good deal when you consider the included charger. Power and reliability make it an excellent all-around deal.

This battery has been an absolute workhorse for me. I can power my monitor and external sound recorder for several hours with no problems. And as you can see from the price, it's a fantastic value.However, it lacks some of the additional power ports that are popular these days (it only has one D-Tap output and one USB-A port) so you're almost obligated to use this with something like SmallRig's battery adapter plate, which gives the battery several additional options for sending power.If you need modern tech, I'd look into SmallRig's battery offerings, but if you don't need all the bells and whistles, this battery is very solid, and will definitely be a backup battery for me moving forward.

I recently purchased and it has exceeded all of my expectations! As a filmmaker, having reliable power on set is crucial, and this battery delivers. It holds a charge exceptionally well, powering my DSLR rig and other equipment for extended shoots without any hiccups. The 95Wh capacity is perfect for long sessions, and I don’t have to constantly swap out batteries.The V-mount design is solid, locking securely into place, so I never have to worry about it slipping off during filming. It’s also lightweight and compact enough that it doesn’t add too much bulk to my setup. The build quality feels premium, and I appreciate that it has both D-Tap and USB output options, making it versatile for powering additional devices like monitors or lights.Overall, I’m highly impressed with the performance and reliability of this battery. It’s an excellent investment for anyone looking for a dependable power source on professional shoots. Highly recommended!

So far so good on this battery. I didn't expect a charger to be included, which was a nice surprise. I ran this for about an hour the other night at 50% capacity and it still had all the bars. Not entirely sure how accurate those are in terms of dropping rapidly past a certain point. But it held up well, so it feels like a great value. I may update this in 6 months. It will get heavy use during the summer months.

Bought one to try out, I'm very picky with my gear where I mostly work with Arri and Red cameras, and use Anton/Bauer and Core SWX/switronix batteries. Decided to try one of these and I really loved it. I own four now for my Red. A very good cheap battery, but the best is they charge very quick and each comes with their own individual charger, where the high end chargers can be pretty expensive for a 4 bank. Definitely recommend.

This battery has been running my Sony A7s iii and ninja v for much longer periods of time than I expected. I’ve rolled continuously for 1 hour and 15 minutes and the battery meter still read 100%. I bought two of these batteries and have not needed the second battery yet. Of course my shooting pace probably differs from yours so I can’t say you’ll have the same experience. Suffice to say these batteries will extend shooting time way beyond camera battery shooting times. Especially with the ninja v which is a real hog.A camera rig audio note: Also tried tapping the usb socket on this battery for a tascam field recorder which is frequently part of my rig. Though the power supply worked great, this configuration caused a problem with audio in the camera body (you may have read about this issue in camera forums) that would make audio syncing in post difficult. If there’s a way to fix this issue I haven’t found it yet. So I find it necessary to run separate power for audio.Bottom line, great battery.

Sometimes shoot days are long and internal batteries are alot to carry around and fumble with. This V-mount battery is a life saver for that! it works. Its simple easy to use and works.

Over fourty charges so far without any problems. I power a Pocket4K, an external 7 inch screen and occasional LED light. Four hours every day shoots with lots of power left over at the end of each day. The included charger surprisingly works fast and reliable too.
