K&F Concept Osmo 360 Osmo Action 5 Pro/4/3 Battery Charger, 3-Pack 2100mAh Action 5 Pro Batteries & 3-Slot Fast Charger Compatible with DJI OSMO 360, DJI OSMO Action 5 Pro, Osmo Action 4, Osmo Action 3

The best buy if you have a 3,4,5 action the batteries are the same for all models and they work perfectly like the original.

I bought this for my trip with friends and was able to shoot more than 6 hours nonstop in 4K.

I validate this purchase but especially the brand that is the best in terms of equipment for DJI 3,4,5

Perfect! It works really well.

I have owned and reviewed several K&F Concept camera accessories, and have always been impressed with the quality in terms of design and manufacturing, especially when you consider how reasonably priced their items are. This 3 pack Osmo Action camera batteries and a charger is no exception.As usual, the items come in a K&F branded box. Inside is the charger, the 3 batteries and the USB-C charging lead. Note, you will need a power supply. I used a multi-USB Fast Charger that I had purchased separately. The batteries did arrive drained, so I did need to charge them before use. Charging times are not especially fast, nor are they slow. Around 4 hours for all of them to be charged. I suspect it would be quicker if I were charging one at a time. My only minor criticism is that I wish there were a better indicator other than red or green. At least an amber, or better still, a percentage meter. However, considering the price, this is a minor quibble. With regards to use with my Osmo Action 5 Pro, the batteries worked really well. I have used two of the 3 so far. I was just shy of the advertised 120 minutes of recording time. I achieved 110 minutes the first time, and 118 on the second time. But those times are similar to the times I get with the original Osmo battery. I had no issues with the batteries feeling hot whilst they charged (they barely got warm, let alone hot), and having had other batteries from K&F, I trust them to be safe. All in all, they are hard to fault, and therefore worthy of the full 5 stars.

Pretty good charger pack and with the batteries makes it ideal when you need it out and about

useful but batteries die quickly , but that my be the nature of such a compact , watertight product with a camera & 2 bright on screen displays

This K& F Concept Osmo Action 5 Pro 3 pack Battery and usb-c Charger is a good value solution to extend the life of the action camera. The charger works on mains and high-powered power banks charging the batteries in a few hours.When you put a battery into the charger an LED goes red to show its charging. It goes green after some time. You would think at that point its charged; except I have taken original and one of these K&F batteries off when the green led was on; that my action pro 5 shows as around 60% (The original was 58 % and the K&F 63%.)Putting them back on charge they were charged up to 100% an hour later.The K&F battery life is comparable to the original I was able to an average record time at 4k120FPS close to 45 minutes with the batteries before they ran out. With the charge time and 4 batteries you can with suitable charging record almost constantly always having a charged battery.

All good

They work well, it's practical, and it's worth it to increase the battery life of your camera.

Impeccable, I only bought it because of the loader. Batteries work just like the originals

Perfect. So far it's going very well.
