Very impressed with this replacement battery. It lasts longer in my Nikon Z7 than the Nikon one, and has direct USB charging. I used this as a primary and the Nikon one as a backup, and I will get another one soon. Great value for money.

Equivalent fit to the Canon original, at a much better price. Charge performance seems good, but haven't run a direct comparison. USB charging alternative is a bonus

Got this as a back up to the Panasonic battery that came with the camera. It actually seems to last longer than the Panasonic original. Its also very convenient that you can charge it with the USB cable and don't need a special charger. Great when you are traveling.Would certainly recommend.

Works fine with my Z8. Lasts for 6-8 hours a day. Have used it for a week now.1. Value for money: 3-4 stars. Depends if you can buy it with an offer (4 star for offer and 3 if you pay full amount). Bought this one for £34. The other spare battery I bought was from small rig and cost me £30.75 (under offer).2. Durability: No comments....will update in 6 months.3. Battery back up: Haven't compared with the OEM or the Small Rig....but almost the same as the small rig.

I'm not a professional photographer but a keen amateur so my expectations and demands are lower. I have three of these for use in my Sony A7 and the only 'problem' is the camera splashes up that the battery isnt Sony and do you want to continue. So that's more of a Sony protectionist policy and nothing to do with Neewer.I've not tried to count the number of picture / charge cycle because I'm not often taking 100's of photos in succession. On one occasion I took fast burst photos of a bride and groom opening a bottle of fizz - the groom struggled so there were well over 150 photos. The battery was un-phased by the power demand and I got the photo I was after.I really appreciate the USB charging and the price point. I have 3 of these beauties plus the original Sony. These three are the ones I use.

Very pleased with this battery in my Sony A5100 camera. Removes the need to carry around a micro-usb lead (no-one uses them any more) as battery is easily charged with usb-c outside the camera.Upon plugging in to charge there is a little red LED, and when battery full this turns green. Convenient. Time will tell whether the battery life holds up, as so many third party batteries seem to die quite quickly, but so far works well. Will probably be buying another.

I love the fact I charge these on the go with the direct USB-C but apart from that, they're not up to OEM standard.I have the Fuji NP-W235 version and whilst it works in the camera fine it doesn't last as long as a proper Fuji battery.Also, they don't hold charge well when stored - when fully charge up, leave them for a few while and they slowly discharge. I know this happens with all batteries but it's very noticeable with these.I have to check they're still fully charged before I take them out which is a pain because you just want to grab and go not spend an hour recharging spare batteries.

Arrived quickly and it works fine on my camera.
