Ultimaxx Mavic Air Accessories, 4 in 1 Rapid Battery Smart Charger Doc Multi Battery Intelligent Charging Hub with Charge Indicator LCD Display

Well put together and provides a battery readout LCD which provides valuable information while charging. Cost is very reasonable and easy to use. Less than half cost of other brands, but function is exactly the same. Now I can charge all 3 of my Mavic Air batteries at the same time, instead of one at a time. Highly recommend.

Maybe I just got a dud, but I have tried multiple times to get it to charge my 3 batteries and it will charge the first up to about 55% and then quits. It never tries charging the others unless I remove the partially charged battery and then it only charges the next one up to 55% and quits again.

Just arrived and is simple to set-up and use. One thing I did not notice when I ordered is that this version, unlike the DJI one, does not fold up to a smaller size. At first I was disappointed, but now I wonder if that means it will be more durable without having moving parts pulling at wires. Like the DJI version this one charges the fullest battery first, and then goes to the next fullest on down the line. It does not charge all four batteries at the same time.reading the directions that come with the unit is challenging because of typos and translation issues, but the unit is pretty simple to figure out.

Minor complaint: it's difficult to get the batteries properly aligned with the charging base.Major complaint: two of my batteries (one older and one brand new) will not fully charge on this charging station. If I plug each battery directly into the charging cable they will charge fully but on this charging station they will only charge 75%, even when left overnight.

Works Great. Arrived very fast.

I got this in hopes that it would charge multiple batteries at once, but really it just charges your batteries one at a time so you don’t have to take your batteries in and off the charger to swap them out. It uses the power supply and charger that comes with the drone itself, so you’re basically using the power it takes to charge one battery to charge up to four.The most irritating thing about this accessory is that it takes longer to charge one battery on this than on the normal charger. It’ll sit there and “check” a battery for a good 10 minutes and then decide “oh, I should probably charge this.” If you have all 4 batteries on here, they won’t all be charged for probably 6 hours.Overall, it does as it’s advertised but what it really does is just save the hassle of having to get up and take the charged battery off and the next dead one on to the charger. If you timed it right, it would be faster to charge it that way than with this thing.

It's awesome for the price quick charge

Got a defective product. Never worked. Don't buy.
