I've been using these batteries for a few months now, and I'm very happy with their performance. Often when inexpensive batteries, self-discharge is an issue, when leaving them unused over time, but these really hold their power well. I left one sitting for over a month, and it was still showing a full charge when I needed it in a pinch.As far as battery life goes, one of these will power my camera and audio recorder fully for over 5 hours easily, and still have some charge left in them. I've never run them past that, but it seems like they could probably go quite a bit longer.Finally, the build quality is excellent. I dropped one of these 2 stories over a balcony. I thought for sure it was going to be dead, but I picked it up, checked it, and it's been working fine for months since that incident. Now, I can't even tell which battery I dropped, because absolutely nothing broke off the battery. I still wouldn't recommend doing this intentionally, but I'm happy that it weathered the storm without any damage whatsoever.It would be nice if a newer version of this maybe had a PD port instead of a USB-A port, but I'm not going to count that against this battery. It has a USB-C port for charging, and there are adapters so that you can use USB-A to charge just about anything. Overall, I am very happy with these batteries, and I would definitely recommend them.

I’ve purchased quite a few NP-F style batteries on Amazon before and unfortunately many of them seem to stop functioning after a few months. These however are still functioning 6 months after purchasing. These also are great because I use the battery plate on the back of a light or monitor to power the light/monitor, but also the USB-A output at the same time to power a wireless HDMI transmitter. Being able to use two separate outs from this one battery makes it much more usable and valuable than a standard NP-F battery because I’d need to get a separate battery plate with multiple outputs to achieve the same functionality if not for this batterie’s USB-A output. I do have to sometimes plug in the USB-A first then mount the battery onto the light for it to send power to both outputs, but that’s not a problem. Also the USB-C charging input is extremely convenient. Just pop it on a usb-c charger and away we go. No need to worry if I forgot my NP-F battery charger when I’m out and about and run low. I say, the more input and output options the better for flexibility. :)

Using these on a Wireless HDMI transmitter and receiver pair. They last a very long time. I really appreciate the ability to run extra small usb devices from these batteries while they are powering the main devices.That is the only device I have that requires these kind of batteries. But after discovering how versatile they are, I've begun looking for other devices that may share these batts.

Love them

UPDATE: After trying both built-in charging ports over a couple of days, I finally tried an external charger and that worked! I am disappointed that both of the built-in charging ports didn't work for one of my batteries, but with this work-around (the external charger) the battery is back and working well.Also, the seller reached out to me to try and resolve the issue but I found this solution, so I did not take advantage of their customer service offer.ORIGINAL REVIEW:The features and built-in recharge ports, as well as the LCD and capacity all seemed great for the price. Unfortunately, one of the two batteries fully died and won't recharge after 10 uses in less than 1 year.

I just got a set of these for a shoot I have coming up. Not wanting to get stuck with bad batteries, I took one of the batteries right out of the box and put it on a 7" LED light panel. I didn't pre charge the battery, and knowing that batteries self discharge after a few days, I had moderated my expectations. The first battery powered the LED panel at 100% brightness for just a little over four continuous hours. This is pretty impressive and assures me that I dont have a lemon. My plan is to test the second battery in the same way. I will come back and update this if the second battery underperforms the first. Only time will tell if these are high quality batteries and hold up to field use, but so far, I'm quite impressed.

So i bought this battery for hopes of being able to power my light for a longer period of time....the first set that I bought worked fine for a few days untill one of the batteries just stopped charging or holding a charge but i was withing the return policy. So i returned them and got some new ones which worked fine untill now 4 months later.... and now one of the batteries did the same thing. it doesnt hold a charge nor will it charge at all. this is disappointing and now im past the return policy. Not sure if they have a warrenty but ill update with more details of this experience later.

These are very good high quality batteries. I did not test them live as they were ordered in error, but when I need to replace my current set, this will certainly be the set that I go with. I used 1 of the batteries this Sunday.. this is for our Floor Camera and it powers the Transmitter to feed to the live mix. The First Battery performed great this week with more than enough power to get the Job done!
