EN-DM-I227A Drone Battery Charger for DJI Inspire 1, Inspire 2, Matrice 200, Matrice 600 Battery TB47 TB48 TB50, Intelligent Fast Multi Battery Charging Hub Station (Charge 3 Batteries & 2 USB Ports)

Though not advertised to do so, the top USB port SUPPORTS FAST CHARGING as needed by DJI's Smart Controller! This is the only multi-charger for the Mavic 2 that I am aware of, that supports USB fast charging. I'm not sure why (at the time of this writing) this listing, the owners manual, and the manufacturer's website all say "USB: 5v, 2A x2", but that is not correct. Maybe the design was recently updated? I've tested both USB ports on my unit (which I ordered late November 2019) using a MakerHawk USB3.0 Tester/Power Meter (while charging the DJI Smart Controller, as well as while charging a Samsung QC-compliant Galaxy S7 cellphone) and can confirm that the top USB port supports 5v, 9v, and 12v charging voltages - the USB test meter reports "QC2.0" when charging these. Furthermore, the voltages and currents measured are nearly identical to those when DJI's fast charger (which is included with the Smart Controller) is used - about 12.2V @ 1.93A. Bottom line - I feel completely confident in charging my smart controller using the top USB port of the M221A - what a pleasant surprise! As far as the bottom USB port goes, it's your basic 5V, 2A port as advertised.Flight battery charge ports:I am happy with these as well. Though the reported voltage (on the built-in Volt/Amp meter) on my unit is slightly below the DJI battery rating of 17.6V, I prefer this slightly lower voltage of around 17.5, as it puts less stress on the batteries without significantly affecting flight time. Also I should note that Port 3 shows a slightly different voltage from 1 and 2 on the meter, but I think this is an artifact of the possibility that this port is used to power the digital volt/amp meter and this throws the reading off a bit. The voltages measured at the three concentric connectors on my unit were nearly identical - I made a test fixture and moved the same battery to each port one at a time to verify this during the constant-voltage portion of the charge. The ports are completely independent, and were found to be equally adjusted (within 25mV), though the built-in volt meter suggested otherwise. For me, the indicated charge CURRENT tells the most about the remaining charge time when using this charger - you can see the initial constant current around 4A, then as the battery reaches its target voltage, the current will taper off over time to something close to zero indicated, shortly before charging completes.Somebody mentioned in another review that the battery connectors don't have a good feel or don't hold onto the battery very well. This may have been updated as well since that review. Mine look nearly identical to DJI's connectors AND THEY HOLD ON BETTER. In my opinion the DJI factory battery charger's connector is actually quite loose on the battery and feels much less secure than the Mavic Pro Platinum ones did. M211A's connectors feel just fine - similar to the fit and retention of the factory Mavic Pro Platinum, which I previously owned. To avoid confusion here: The M221A is for the Mavic 2 (Pro or Zoom) not the older Mavic Pro - I'm just making comparisons here.I also like that the flight battery charge cables are REMOVABLE from the charger. This allows the charger to fit into a travel case without binding or damage to those wires (see pic).Charge time:In my testing, a Mavic 2 battery that is discharged to 22% (you get the low battery warning at 25% and it takes 3% more to get on the ground) takes just under an hour to fully charge. Charging one, two, or all three batteries plus USB has no effect on the charge rate.Noise level:The fan on my M221A is impressively QUIET - no complaints!Summary:If you own a Mavic 2 with Smart Controller as I do, then I highly recommend this charger. It is equally suited to the standard controller as well of course. I have now modified my hard case to carry the M221A only - no factory chargers travel with me.

I bought this unit as a replacement charger for my DJI Phantom 4 Pro. It's such a great product, I don't know what I did without it before. First and foremost, it charges 3 of my phantom 4 batteries all the same time! 3 at the same time! My work requires me to fly my Phantom 4 for a extended period of time and therefore, I have several spare batteries. The ability to charge 3 at the same time, saved me money and precious charging time. One of the charging cable also let's me charge my remote control along with the batteries. So, I am really charging 4 things at the same time. I have used this product several times now. It is working great, the LED screen provides me the charging voltage and amperage of each charging port and the 2 additional USB Ports come in really handy as well. I can use them to charge my phone and tablets. For the price this product is a must have for all Phantom 4 pilots.After more than a year, the products are still running well. I think the quality of this drone charger is very good.

I keep my P4 up in the air as much as possible - sometimes 15+ flights a day. With six total batteries and this charger I never have to worry about having a charged battery. Batteries stay cool during charge and it's nice to see the amp draw on each channel instead of relying on which light is flashing on the battery.Seems well built and the cables are replaceable if you damage one. The box gets warm when charging three batteries simultaneously, but the internal fan is quiet and keeps up well on the heat dissipation. It runs with no issues on a 400W inverter.If you're cycling lots of batteries this is a must-have item, at a great price too.

I Bought this thinking it would be nice to have a simultaneous charger, 2 of the ports for the Inspire 1 chargers didn't work right off the bat. I would plug them in and it gave me 1 or 2 blinks of the battery lights, then go straight to the last light and rapid blink. it would never charge, hot or cold, didn't matter. One of the Cables just didn't work in general. Well just took it out and noticed that after charging all the batteries on the 1 that worked my batteries went from 20ish minutes of flight time to 9-12min of flight time. I have been trying to find a way to get in touch with them because it ruined 5 batteries. I don't know why this happened, or how to get in touch with this company!

I train public safety agencies how to fly drones. I needed a rapid charger so we could keep the Mavic 2 Enterprise in the air all day. The first time I tried to charge battery packs with this charger the batteries just flashed and wouldn't charge. I assumed something was wrong with the charger. I was about to return it and then I noticed what appeared to be a clear insulation on the plugs for the battery charging cables. It looked like clear tape. It was difficult to see and I almost missed it. I cleaned off the plugs with a razor knife and the problem was solved. I put this charger into service today as I trained 5 drone pilots. It performed flawlessly all day, charging packs in half the time of the stock charger. It easily charged 3 packs at a time. I do recommend the charger, just be aware of this minor detail.

Finally a charger worthy for dji mavic air, has a LED display that controls both amperage and voltage immmediato, a fan that serves to cool the case robustly and elegantly in aluminum and fast in charge, has simultaneously loaded three mavic air batteries and the radio control in just 62 minutesUnique and only I had to buy it in the US because in Italy they do not sell it but there are chargers that do not have the same power very low and do not charge the batteries at the same time .... buy it without thinking of a great charger with low price and extreme quality.Excellent purchase

Este producto se supone carga 3 baterías del Drone simultáneamente, dejo de cargar una por principio al poco tiempo de uso pero con un poco más de tiempo descubrí que termino dañando las baterías todas se inflaron y no se lo atribuía yo a este equipo pero recién quise cargar 3 baterías (ya unas nuevas no las mismas) y dejo de funcionar otro de los puertos de carga y se calentó muchísimo como nunca el cargador por lo que pienso que fue lo que provocó el fallo en las primeras 3 baterías del Drone que usé con el y no son nada baratas esas baterías inteligentes, mejor usen el cargador original.

Me soluciono el problema de mi cargador de bateria es un producto muy bueno y entregado en tiempo y forma le doy un 10

Seams to work well, the fan is little noisy & I would like a on off switch but works well

Excelente producto. Cumple perfectamente. 100% recomendado.

Chargers quick good quality productItem came fairly fast to my house durable well-built quality
