Anbee3-Ports Intelligent Battery Charger for DJI Air 3S Drone, Portable Quick Charging Hub with Storage and Discharging Mode Compatible with DJI Air 3/3S RC Quadcopter

The item arrived, the quality is good

Charge up to 3 batteries for your Air 3 drone. Charges as expected, small footprint. One of the stickers came off the bottom of the charger, but that doesn't have an impact on functionality. Comes with 2 white usb charge cables and instructions.

When I got my DJI Air 3 I chose the Fly More package, which came with the DJI Charging Hub. But I got this charging hub for its ability to charge the batteries up to just a storage level, which is key to getting your lipo batteries lasting as long as possible.While it's true that DJI smart batteries will self-discharge to a storage level if they are not used for a period of time, it takes time for this feature to kick in and the actual discharge is fairly slow so the battery doesn't heat up too much. And this feature WILL extend the life of the battery, it's a good solution to the problem of battery life.But it's not the best solution, which is to charge batteries only to storage level if you aren't planning to use them right away.This has been difficult with DJI batteries in the past as you'd have to find a charging lead that would allow the battery to connect to a regular lipo charger. Then you could use the storage feature of the regular lipo charger to get the battery to a storage charge.This charging hub helps simplify that process somewhat. When you are done flying you can simply charge the batteries on the hub using the storage mode and you're done. And if you didn't use all the batteries, you can use the charging hub as a power bank to bring the battery level down, and then use the storage feature.The hub itself is well made and there were no problems attaching the batteries or activating the different modes (full charge, storage charge & power bank). The batteries are charged in sequence from highest level to lowest level and there is a charging light next to each battery showing its charging state (red for charging, green for done). How fast it charges will depend on how much power you feed it, so a 100w charger is ideal for it.
