Review on 🔌 CYNOVA Two-Way Charging Hub for DJI Mavic Mini & Mini 2/SE - Battery Charger and Drone Accessory (Note: Compatible with Mavic Mini & Mini 2/SE) by Tay Fair

This charger works as expected. Contrary to other comments, however, this device charges two batteries at the same time. I've been using my USB-C PD charger for just over 3 hours, the two batteries are charging and blue almost at the same time. Tried several times, 3.5 hours is enough for two batteries, with my USB-C PD 20W charger. Based on the Revain product video, the charger comes with a USB cable. But not in my case. Just the block, I must have a USC-C cable for this charger. Documentation is minimal. For example, I didn't find any mention of the power button on this device. The LED is not very informative: it does not blink, red means charging or low voltage; Blue means full. However, if the charger is not connected to a power source, the blue LED will remain lit when the battery is low. A little confusing. Conclusion: It works and the charging process runs simultaneously for both batteries. For the price it's a good buy.
