TELESIN Osmo Action 5 Pro 3 4 Battery Charger for DJI Action 5 Pro 3 4 Triple Slot PD3.0 Fast Charging Case with Type-C Cord Batteries Case Fully Compatible with DJI Osmo Action 3 4 Batteries

Works excellent! I have no clue why people claim it won't close with batteries in. It closes perfect!

This has been working well. It charges the battery with the highest charge first, then the second highest charge, then the lowest charge.It's fairly compact and ready to take along.My unit has 1 LED status bulb that never worked, but the device has been working well otherwise and it's so much cheaper than the official DJI device!

I went with the base kit for my DJI Action 4 cameras, but was surprised how much DJI was charging for the official batter case. I took a chance on an after market product, and was not disappointed. The TELESIN battery charger simultaneously charges 3 batteries, and is very durable. The case bounced around in my backpack for several days of adventuring, and held up great.

Very easy to throw in the bag with the rarest of your gear

Works well, just thought it charged batteries while on the go. Looking forward to an updated version. Overall good product

I am changing over from GoPro to DJI and picked up an Osmo Action 4. So I ordered this item after purchasing two more DJI batteries for a total of three. The DJI battery case/charger is absurdly priced so my hopes were high for this product. Glad to say that it works as advertised, mostly...Charging: I am not so sure this is a fast charging product. I used a 52 watt PD 3.0 charger and the three batteries were about half full. It still took about 60 mins to charge them. 95 mins for all three if they were completely dead seems iffy. The description indicates that it charges the batteries simultaneously. I am not sure about that as when three batteries needing charging are inserted only one of the battery's LEDs blink, indicating charging. In the case where you need a battery ASAP, it seems it would be faster to charge one at time vs all three more slowly, so this seems a possible benefit to me.Size: I prefer the rectangle design of this product vs the cube design I had for my GoPro battery case. While this one is longer, it is also thinner. I feel it would be a better design for slipping into a pocket or bag.Ease of Use: It works as designed, for the most part. In the description it says "The red light means charging, and the green light means the battery is fully charged or in idle mode". There are no colored lights on my product. Each battery has four small LED circle lights. When it is plugged into a charger the LEDs indicate the state of the battery (charging or not) and the level of charge. They are off when not connected to a charger and opening the lid does turn on the lights and they indicate level of charge. The lid itself does appear to have a magnet and closes securely, however, the lid does not have any latch. The battery case can work as a charging device as well. I plugged it into my phone using the provided USB-C cord and it started to charge my phone, though itt does not fast charge my phone (Samsung S23+).Quality: The fit and finish are appropriate for the price. There lid has a single hinge point in the middle and appears sturdy enough with normal use.Overall, I am very happy with the product and can recommend it to you.

Holds microSD cards well, holds batteries well, charges batteries fine. The lid will not close with batteries in the case… dumb design.

A 3 battery charger seems kind of odd at first, but actually makes perfect sense. It's pretty common to find batteries that come in a 2 pack with their own charger. But most of the chargers are pretty lame, lights to let you know the batteries are charging/charged, but not the level of charge. And most of the lids snap shut and are difficult to open, especially with wet hands (it IS an action camera).Enter the Telesin charger. Really thoughtful design: ribbing on the body of the case so you can grip it even with wet hands; magnetic lid that easily opens and all but closes itself; 4 led lights for each battery to let you know the charge level of each battery; slots to store 2 micro SD cards; USB-C connection (because everything is USB-C now); nice rounded corners so it doesn't get caught up on things in your camera bag, and fast charging. It takes about 1 hr 15min to charge 3 batteries with any charger 12v 2A or more (which you can use because of the protection circuitry).So what's so great about having 3 slots? With the 2 slot chargers, if I've drained my main battery and 2 back-up batteries, then I have to use 2 USB cables and chargers/USB ports to charge the 3 batteries - 2 inside the charger, 1 in the camera itself. This Telesin charger solves that problem and charges all 3 at once while the camera takes a break and cools off.As far as others mentioning that the lid won't close? I think that they are either a) using the wrong battery (unlikely), or b) got a bum unit that they need to return, or c)expecting the lid to "snap" shut like the cheapo chargers, which it won't do because it's magnetic.All in all a simple but brilliant piece of kit that anyone with on Osmo Action camera should own. Keeps your mind off battery issues and lets you focus on using the camera
