Bought these to use with my Z6III.Used on a wedding day last week and they performed great. It was a long ceremony, about a good hour (church wedding) and they lasted without any problems in 4k 24p and with zero over heating warnings.I did test them previously and got 1hour and 12 minutes at 4k 60p until the battery ran out, Around 25 minutes less than the original battery.I also used a white 2600mAh Viltrox battery on the same wedding day and found these were only slightly behind in terms of power in real world use. That Viltrox battery was £40 for 1, these are £26 for 2. So great value for money.Regular usage will tell me how well they hold up over this wedding season, will come back and change the rating as appropriate if they give me problems.So farGreat value,Charge quick enough,Worth the money,I bought 8 of them.

Bought as spares for camera - arrived promptly and charged OK - noted some buyers had problems but not me, charged well - unknown how long they will hold their charge but so far so good - great for the price 👍

Always anxious about these small usb chargers but this is a very good one. Easy to understand display of battery level and charging.Batteries included are very good and a single battery generally lasts al day in my camera.

Quite quick charge, great to get 2 batteries charged at same time for a long day shooting or in very cold conditions.

Managed to record 4k 60fps video with fully charged battery for 59 minutes. Approximately 1 hour. This is behind original Nikon battery. But you get 2 batteries for £25 which is bargain.Only time will tell how it hold it up.

Seems like a well-made product - only time will tell

Arrived on time, well packed & does what if says
