The K&F Concept Insta 360 X4 Camera Battery Bundle with Charger is a MUST HAVE for those looking for some affordable battery replacements for their Insta360 X4. At the cost of less than one OEM Insta360 battery, you are provided with not one, but TWO higher capacity batteries along with a nice compact charger and USB-A to USB-C cable for charging. Build quality is nice and seemingly more rugged and a bit improved over the originals, with metal battery release prongs instead of the plastic ones that the original OEM batteries are made with. The rubberized water-tight seal is evident on both replacement batteries and they both fit nice and snug in the battery compartment of the X4. Capacity shows 2350mAh for the K&F batteries vs the 2290mAh on the originals. Basically 60mAh higher, although not sure how much longer it will power the camera vs the original. When snapped into the camera, the batteries both came showing that they were pre-charged at the factory, with just over 60% power remaining. Will have to see whether the battery capacity continues to retain nominal charge once I have more extensive use with these batteries. In the meantime, having the charger available to keep spare batteries charged is great instead of having to charge the batteries in the camera; allowing for extended use of the camera when needed. Surprisingly, the weight of the K&F batteries were seemingly a touch lighter than the OEM battery so I’ll have to keep an eye on whether the battery capacity is truly as stated. For now, I’m happy with the bundle as it allows me to go on trips without having to worry about running out of battery power at inopportune times. Again, for the cost of less than one OEM battery, you get two spare batteries AND a charger so this is a no brainer. Two thumbs way up for the K&F Concept battery bundle. Definitely a good purchase for your X4 camera!

These batteries work great! They fit perfectly in my cameras and have a long lifespan with each use. The charger is excellent—I can keep my batteries cycled and never run out of power.
As for water resistance, I haven’t tested that, as I always keep my camera in a case when near water. Most importantly, the batteries work without any warnings. I’ve gone through several batteries that all had warnings, but not these!

Two for the price of one compared to other batteries? You can’t lose. These are a winner!

The batteries are perfect for additional recording time and usage time!

These K&F Concept batteries for my Insta360 X4 are exactly as described. They work perfectly, and I love having the extra batteries on hand so I don't have to worry about running out of power during a shoot.

The included dual charger is convenient for charging both batteries at the same time. It seems to charge them quickly, and the LED indicators let you know when they're fully charged.

The price for this two-pack of batteries and charger is excellent. It's much more affordable than buying the official Insta360 batteries, and I haven't noticed any difference in performance.

Pros:

Batteries work just like the original
Dual charger is convenient and efficient
Excellent value for the price
Extends recording time
Cons:

None so far!
If you're looking for spare batteries for your Insta360 X4, I highly recommend this set from K&F Concept. You can't beat the price or the convenience.

EXACTLY AS DESCRIBED. Fast shipping and they work great. All fit and connect to make the additional battery time needed for our trips. Several day trips of skiing in northern California.

This winter we will be shooting a series of International Snow Ski Trips. First is a week in Utah at Park City and Canyons and Deer Valley. Plus a planned trip to Whistler and Blackcomb in western Canada.

And the Big Bucket list trip of 2 weeks in the Alps with 3 days at Les 3 Valleys in France, 2 days at Zermatt, 2 days at Andermatt and Gemstock, 1 day at Livingno and wrapping it all up with 5 days at Dolomiti Super-Ski in the Italian Dolomites.

I am taking my 25 and 20 year old Grandson's and two friends on the trip of a lifetime. Needed these additional batteries to capture the history for our Blog and Website.

I was hoping that these batteries and the charger would be as listed and they truly are. The packaging was great and everything charged as expected.

These provided the running time as shown and charged as specified. Having the dual charger is a great addition.
VERY HAPPY WITH THIS ITEM.

K&F Concept is rapidly becoming my go-to for many of my needs in the photographic world from filters to now batteries! I have been more actively using my Insta360x4 and having these additional batteries has been great!

The batteries fit snugly in their charger which comes with its own cord (all standard fittings). After a charge-up (there are indicator lights on the charger base) I installed one into my camera and was off! No error messages or compatibility issues were observed.

The batteries are every bit as powerful as the OEM so no degradation of power/life and the unit didn't heat up more or less than usual.

I do wish these had come with some sort of case for the batteries but that's a small little nag on my part - not worth removing a Star (IMO).

Thank you, K&F Concept for another great product!

Having tested the K&F Concept Insta 360 X4 Battery and Charger, I can confidently say this dual-pack is an essential upgrade for anyone serious about capturing immersive content. With a generous capacity of 2350mAh, these batteries provide impressive longevity, easily lasting through extended shooting sessions. The dual LED fast charger is a game-changer, allowing you to recharge both batteries simultaneously, which is perfect for those on-the-go shoots. The compact design also makes it easy to slip into a camera bag without adding bulk.

While the performance of these batteries is commendable, there is a minor drawback: the initial charging time can be a bit longer than expected for a fast charger, especially if both batteries are drained. However, this is a small trade-off for the reliability and extended run time they offer. Overall, the K&F Concept Insta 360 X4 Battery and Charger set is an excellent investment, ensuring you never miss a moment while filming.

Nice convenient charger and batteries. It's really easy to power the charger and I was able to charge using a battery bank with USB C. The batteries themselves worked great and as expected.

These batteries have been a lifesaver (oops, I mean, really helpful!) for my action camera. I used to constantly worry about running out of power mid-adventure, but with two batteries and the dual charger, I can keep filming without interruption. They charge quickly and seem to last just as long as the original. Now I can focus on capturing the action, not conserving battery life.

Great to have an additional set of batteries in the backpack for my Insta. I've done some testing with these batteries and they seem to last about the same amount of time as the OEM one does. The charger is good, charges the batteries at a good rate. I like that it has both USBC and micro usb input which gives you options when you're out and about with limited cables.
