quality product very well made, works perfect on nikon z50ii good battery life and fast charge

Great extra batteries with charging port. Using for several months and still going strong. Great value.

So far so good with these. Seem to last as long as the original Sony battery. Have updated my A7III to the latest firmware v4.0 (11/03/2021) and have no error messages about the battery. Like all batteries it's best to charge them to 80% if you want them to last a lot longer. A nice touch is that the charger has a USB-C port on it as well as the micro usb.They don't hold the charge as well as the original Sony battery. I estimate that I'm getting around 70%. Overall for the price I'm happy. Get them and keep them in your kit.

I use the batteries for more than a year now. They are but shorter on life than the originals but still great value for the price and does the job well.

Excellent and reliable batteries. The charger is also very useful and has Micro USB and USB C inputs. Unfortunately Sony has released new firmware (2.01 on the A7IV and A7R5) that detects 3rd party batteries such as these and displays an error. They still work as before but you do not get a percentage charge display after the error message. I suppose the camera and battery manufacturers like to play "cat and mouse" with each other..!

Good value working alternative to Nikons EN-EL25A Z50II battery

They hold a charge and work just as well as the much more expensive Sony batteries. They look and feel quality and the charger works great. Very happy with the product.

I have no idea what on Earth Sony was thinking about selling their latest camera models with no charger, instead relying on in-camera charging (with that price tag as well!), so this pack stands in as both a charging unit plus two spare batteries.Thankfully it’s well manufactured, the base holding batteries snugly should it take a knock, with near equal battery performance to the official Sony battery. I’ve run no tests to authenticate the claim, but I’m frequently mixing between official and third party and not noticing the difference.A drawback would be that when charging two batteries simultaneously one battery will draw more power over the other, so you will want to keep this in mind when cycling between charged and drained and not pulling out an incompletely charged cell.So far I’ve not had any issues with them. If you’re like me, grab this for the dock with the advantage of two decent batteries - it’s the same price as first party and you get twice as much. Just make sure you’ve a few first party batteries to fall back on for guaranteed reliability.
