360 X4 Battery for insta360 x4, 2-Pack 2500mAh and 3-Channel Type-C Fast Charger Case Compatible with Insta360 X4 Action Camera Batteries and Charger with Misro SD Card Slots

This thing is great. It's functional and small and worth the value. It charges fast and the storage space for micro SD cards is actually helpful (especially when recording at 8k). Thing of note is that it's not a power bank. It's simply a charging port and case for charging multiple batteries at once.

This product worked well. It provided a location to not only store batteries, it kept the batteries charged as well, with an indicator light. This made it easy to determine which batteries were ready to use at a glance.

I’ve been using these batteries and charger a few times and so far they’ve had good performance. Nice to be able to put in all the batteries and charge without having to change them out. They seem to be charging simultaneously. Batteries will drain a bit while in storage and this might be a safety feature as it was this way for my drone batteries. Batteries fit like originals in camera and seem to have similar longevity to original batteries though I have not done specific tests to figure that out. The case feels fairly solid and will see how it lasts with use.

The batteries seem to work just fine. I have not used extensively but did use on my most recent trip and they worked well. I like that this case works properly with USB C. I had another case that had a USB C power connector but only worked with a USB A power adaptor. The only disadvantage is the size as it can charge 3 batteries at a time. If you have a need to charge three batteries at once, that is not an issue. I was trying to cut down on the weight and size of my luggage and would have liked to save that little extra space. Not a big deal but I would have rather had it be a bit smaller and only charge two batteries. Really like the charging case and the batteries.

The stock batteries that come with the X4 is a 2290mAh battery. These batteries are advertised at 2500mAh so theoretically they should last longer. I haven't tested them compared to new stock batteries since I've had my cameras for several months now. I think everyone knows that as batteries take on more and more charge cycles, they tend to degrade, especially these small device batteries. I will say that I don't notice any significant difference between these batteries and the stock ones. The both charge up reasonably fast and hold their charge for about 1.5 hours of recording at 4K 60fps. Having an external battery charger is nice and this one allows for a 3rd battery to be charged. The charger is only led light though (red or green), with no digital info on percentage charged. That's fine for standard charging but it does help to have more info on the status of your batteries on the charger. The other funny think I noticed about this charger is that the batteries don't seem to seat into the charger very far. They almost sit on top of the charging pins instead of seating into the charger. I wouldn't move the charger once charging has started, in case the battery moves off of the pins. I haven't had this happen yet but it would be nice if you could feel the batteries get seated.Otherwise a decent charger with 2 batteries.

Great deal!

2 extra batteries for the Insta 360 X4, charging case and power via USB C. Fits snug. No maths involved to charge and the portable nature of the charging case makes sense.

As far as battery life goes, these are shown to be larger than the OEM battery for the X4, but they last about 10% less. On top of that, every time you use the battery, it shows a message saying that it could cause damage to the device.I'm assuming it's just because its a 3rd party battery, but it's still not an amazing thing to see everytime you use your $500 camera and it would be nice if that was noted in the description for the product.
