2 Pack 1800mAh Rechargeable Battery & USB Fast Battery Charger for Insta 360 X3 Battery 360 ONE x3 Camera

The charger works well, and clearly shows the charging status with a bright red light which turns green when fully charged. Each slot charges separately, so you can charge one battery at a time in any of the three slots, or up to three batteries at once. The charger accepts USB-C or micro USB which provides helpful flexibility.The batteries fit well and have excellent battery life. I did not try them underwater, as they do not advertise being waterproof.

Was hesitant, since the product didn’t have any review. However due to time constraints I had to order one from Amazon. Batteries and multi charger worked great with my new X3. Didn’t get a chance to measure performance. What matters is I can charge my 2 OEM batteries at the same time. Now as a plus, I have 2 extra batteries as back up!Just came back from vacation and everything (charger and batteries)worked great for me without any issue. Great value.Take note, as mentioned on description, not waterproof.

Both batteries lasted about as long as the OEM battery in my Insta 360. Unlike most sellers of what looks like the same product, these guys claimed their batteries as NOT waterproof. That said, the silicone seal appeared to be of quality and actually fit a little tighter than OEM. So I would be confident of at least some water resistance.

Bought these as a cheap backup to the $32 a piece Insta360 X3 batteries. They fit fine and work as intended. I wouldn't per se go so far as to say they have the same capacity, but while I mostly ride around town, they are perfectly fine for my use case

My X3 runs 5F to 10F degrees cooler with these batteries than with my original X3 battery. On a sunny day with the temperature in the upper 70s, my X3 overheated with the OEM battery but kept running with these. That was the plus. The minus is that on a cold day, about 40F, these batteries lasted about 5 minutes less than the OEM battery.The 3 dock charger worked fine for these batteries and my original Insta360 battery. After charging in the 3 dock charger, I put both types of batteries in an X3 fast charger and its LED showed the batteries as already charged.I tried 2 other sets of generic batteries for the X3. All three sets came packaged alike, with only the stickers on the box to show the difference. One of the three sets had additional printing on the batteries. All 3 sets behaved the same.

The batteries seem to be slightly distorted and require a lot more effort to install them and get them to lock into place. Once installed, they seem to be fine but just require extra effort initially.

So far so good with these. Battery life so far is on par with OEM. Batteries clearly state they aren't the waterproof kind, which are fine for my use. I'm good with the 1 waterproof OEM battery aside from these. Batteries fit snugly in the charger and don't fall out while driving with the charger sitting in the front seat or dash area.

I use a number of Dongni power options and it is a brand that I do trust which made it an easy choice for additional batteries for my Insta360 X3 camera.Charging is simple and fairly quick and the run time although not as long as Insta360 OEM, is more than enough for a full day of shooting and not worrying at all about the batteries going flat and missing that one last-minute golden hour shot.I've had zero issues and really do not expect any given the other Dongni options that I use daily.Now for the warning. These batteries are not rated as being waterproof which I will take as don't use these in your X3 if you are submerging the camera. This is more of a common sense warning, I have never submerged any camera with anything other than the OEM battery and I highly suggest that you do not either. Swapping the battery is quick so why take the risk?Bottom line, great value from a company I have trusted with so many of my power options.
