Especially since this thing looks so big. I have three chargers and they take up half the space, weight 1/4 as much, and cost the same thing.I followed that thread. A says this, B says that and C says something else.
I'm going to play it safe and use the DJI power supply for the DJI batteries. Seems to me the most prudent thing to do, on many levels.
If this is the unit he will use, and the Amp rate looks good at 30, where are you going to get all the connector ends to plug into the batteries?
I notice a company selling a 4 battery charger, but can't seem to find the amp specs. Might be good, but if it's cheaply made?
