Insta360 One X3 Battery Kit - 2*X3Batteriey with X3 Charger, 1800mAh-Compatible with Insta360 X3 Action Camera- Replacement Battery. (Insta360 X3 Accessories, Insta360 X3 Battery Charger Hub)

This Pocket size charger and spare carry case with batteries work great. Although the batteries are different they supply power well. Not sure of how waterproof they are, so I use original battery for underwater shots. I use the charger case as a pocket carry case which is extremely convenient. It was a great choice at a reasonable price.

Used in the pool and my camera turned off in a minute. It's not sealing good enough.

The charger works quickly and the batteries seem good.I think they may last slightly less time than the oem but are close enough for the price. I am glad to have this product but I would not recommend using them underwater with your insta360 x2 as they are made differently than the original.

I'm leaving my initial review below. I spoke with the company about my problems and they provided a replacement. The replacements had all of the pros of the original but haven't stopped working on me! They were also very prompt in both responses and the replacement. Can't ask for better service.Initial review: This worked great for two weeks. Then it kept stopping after a moment repeatedly with both batteries. The only reason it's getting two stars is because the case does charge the original battery. That's much better than charging it in the device.

The batteries are very strong, the charges last forever, and get charged very fast. Very good

I really like the case, feels a lot safer charging the batteries.
