ISDT MA331 Air 3/3S Charging Hub,200W 3 Channel Smart Battery Charger for DJI Air 3/3S Series,RC Charger with APP Connection/LCD Display and Discharge Function Not Include Battery

This 3 way charging hub works great with my air 3 batteries, the charger has a colored LCD display screen that shows a handful of info, like charging percentage, charge mode ect, the hub also has a fast charge feature that actually charges the battery pretty fast, the charger can also be set to only charge the batteries or discharge the batteries to 50% to help maintain the battery life when the batteries are not being used, another cool feature is that the charger also has an app that can be used to set the charging modes ect, I also like that you can plug two charging cables into the charger to give it more charging power, it also has a type C output port so you can charge the control as well, all in all I am super with the performance of this charging hub, good value for the price in my opinion.

Will not charge the Air3S batteries. I put a Air3 battery and 2 3S batteries in the charger. It charged the 3 battery just fine. but not the 3S batteries. Saw that it MAY be possible to update the firmware but that's not easy to find on their site. It should have come with that update and not caused the user to have to go to the trouble...not worth it. Returned to Amazon.

Great charger i would give it a 5 star review but the app to put on your phone wont download to my phone its like on a timer & it wont download fast enough to install on my phone other users report the same problem but other than that its 1 of the best chargers i believe

The ISDT MA331 Air 3/3S Charging Hub is a game-changer for drone enthusiasts. Its 200W power output and three-channel design ensure multiple batteries are charged quickly and efficiently, keeping your drone ready for action. The integration with an app for monitoring and customization adds convenience, while the LCD display provides clear, real-time charging data. The discharge function is particularly handy for long-term battery care, preventing overcharging or underuse from degrading performance. However, the charging hub’s compact design means cables can feel a bit crowded when all ports are in use. Additionally, while the app is intuitive, first-time users may need a moment to explore its features fully. Despite these minor flaws, this charger is a must-have for anyone looking to maximize their DJI Air 3/3S experience, blending performance, convenience, and smart functionality seamlessly.

I purchased this item in May of 2024, worked fine until recently when it stopped working. Have contacted seller for replacement or refund, but have got nowhere.

If you take a lot of video, you are probably constantly starved for batteries. This charger works impressively fast at charging, and unlike some, actually does charge all three batteries at once, instead of one at a time. This will take some time to figure out if you haven't used something like this before, it's more complicated than a simple charger. But with all the feedback and the Polying app, you can really finetune how this works. As long as you have several batteries to work with, the chances of you running out of power while using this is very low. It's a neatly made device that works great while providing you clear data. In a pinch, you can also use this to charge other devices, it charged my phone without issue.

I’ve been thoroughly impressed with the Air 3/3S Charging Hub. The 200W power capacity and 3-channel smart charging design are a game-changer for efficiency. It seamlessly charges multiple batteries simultaneously without compromising speed or safety. The build quality feels robust, and the user-friendly interface makes it incredibly easy to operate. The smart charging feature that balances the power distribution is a standout – it ensures optimal performance and battery health. This charger has significantly reduced my downtime during projects, making it an invaluable tool in my gear collection. Highly recommend it to anyone looking for a reliable and high-performance charging solution!

This is a 1 star charger as it arrives. If you insert a battery, the battery level and voltage show up correctly, but the battery will not charge. This MA331 charger is sold as an identical model by other brands with a slight change in the name. Reviews from other product pages mentioned that the firmware on the charger needed to be upgraded in order to be used with the newer air 3s batteries. For the ISDT model, you need to download the Polying app. However, when I tried to add the charger to the app, it wouldn't show up. I tried this for 5 minutes. Funny enough, another brand's app did see the charger right away. Right as I was about to give up the Polying app finally showed the charger in the available devices page. I was prompted to upgrade the firmware. After upgrading the firmware the charger behaves as you would expect. It is slightly thicker than the stock charging hub however it still fits in the fly more soft bag. I really like the LCD display which shows real time stats for each of the batteries. You can insert up to 2x 100 watt USB C chargers to charge all of the batteries at once. If you insert 2x 65 watt chargers, you can charge two batteries at once. Even without a charger attached, you can equalize the state of charge across all batteries or move consolidate power from the lowest batteries to the highest. The Polying app is also pretty useful. You can change the behavior from charging the batteries fully to 100% and instead tell it to charge to 99% or 95% fast charge. The last few percentage points take the longest, so if you're optimizing on speed and rate of charge, charging all the batteries to 95% is a great feature.
