Smatree Battery Charger Compatible for DJI Phantom 4/4 Pro/4 Adv (Charge 3 Batteries One by One, Convert Phantom 4 Battery into Power Bank, 15.2V Output)

I have two batteries for my DJI Phantom 4 charging them was hard work. I usually put them in storage mode, so when I want to fly my drone it means the night before I have to charge the batteries. I usually don’t get back from work till late so I set one battery away charging, then set an alarm to wake up an hour or two later to switch them over and charge the second battery. I was put off the official DJI one as it is considerably more costly and charges the batteries in sequence instead of all together.With this Smatree charger I can put both batteries in and not worry about them, they charge to 100% every time and it charges the batteries all together (unlike the official DJI one).The batteries fit perfectly into the docks, no wobbling or loose connections. It uses the original charging lead that comes with the drone so no need for extra cables, also when on a smooth surface there is a rubber lip on the bottom so it doesn’t slide around if you knock it. It works when hooked up to my car charger too, so between driving to locations I don’t have to stop the car to change the battery over once one is fully charged, just leave them to it and concentrate on the driving.The discharge function I’ll be honest I don’t and probably won’t use (as I have it set for 3 days discharge through the DJI app and have external batteries for phone/iPad etc). However it is handy to know its capable of this should I forget to bring an external battery, and its 5V/2A so it will provide a quick charge too. I do use this USB port to charge my iPad while the batteries charge in slots 1 and 2.My only frustration with it was that its slightly too long to fit in the DJI styrofoam case (the width and height are perfect), so to fix this I cut two nubs off the inside of the slot in the case, now it fits no problem and I take it with me as part of my daily kit! (see pictures).Highly recommended to any P4 or P4 Pro owner, cuts all the hassle out of charging!

I’m happy with the multi charging system

Only arrived today, but happily charging my 2x5870mah P4P batteries (in sequence). A nice white gloss surface which matches my Phantom and accessories. Contrary to other reviews here, it charges high-performance batteries, and they fit perfectly.As this uses the original DJI charger, there is no way it could be faster than the charge time for two batteries, and may indeed be slightly slower, but this is made up for by the fact that I no longer have to wait to swap over the batteries when one has completed charging. Also, as has been pointed out in comments, this is NOT a *discharger* (the batteries do that for themselves), but you can use the battery/batteries in the hub to power a USB socket for phones etc.All I wanted, and expected it to be. And massively cheaper than the DJI equivalent. Good job, Smatree.

Charges the P4P batteries quickly and in sequence (not at the same time). Can also use batteries to P4 batteries to charge devices in an emergency. Lost one star as could be quicker... tested and it takes longer than charging 2 batteries individually. However, it’s more convenient and the price is excellent.

I have a PfCO from the CAA so I need my kit to work properly. This a must for anyone who has more than one battery. Of course I can't condone leaving LiPo batteries charging on their own without supervision, but this unit is a great little cost effective piece of kit!Love it! Does what it says on the tin!!

Ideal, perfect to use a genuine "plug and play" item. I keep it in the boot of my car with 2 batteries always charged and ready to go!

Doesn’t work. Had three batteries plugged in first thing in morning, came home after work to find that nothing had been even remotely charged yet lights on batteries were still flashing away as if charging.It was either faulty or takes a week to charge the batteries, either way it is as useless as a chocolate teapot.

Does the job and does it well. Charges beautifully.The USB addition is a great idea and allows for your screen (or any other device) to be charged at the same time. It looks good and fits in with the white of the DJI Phantom 4 Pro.
