Yes it works I just purchased one myself from amazon and it works. I also ordered a power extra charger. Well I ordered 2 buy mistake. This works well also it charges faster than the car charger.

Thanks, I just ordered one. The price is unbelievable...

For those of us in the US, it looks like similar items are starting to show up on ebay.. who is going to be the first one to risk it!?!?

These loaders perform roll of the cells ?? I would believe that for the price they do not do it which I understand is very harmful for the batteries.

To my knowledge, the original charger only supplies a constant voltage of 13.2 V to the battery and the charge controller inside the battery ensures correct charging.

Exactly. The brains are in the battery - not the charger.

Current regulation/limitning is NOT done in the battery and is expected to be done in the supply. Balancing yes.

after an unfortunate mishap with a compromised cell on an old P3 battery I had using a car charger that almost burned my car to a crisp, I dont use car chargers anymore. I use a high quality power inverter and use the original home chargers. Another advantage of this is that I can use one inverter with any of my 7 drones I chose to take with me on any given day.

Can I ask where you got that info from?
The Air batteries are similar to the Pro and Phantom batteries. That's why they're called intelligent batteries and why they cost way more.... They require a fixed voltage, but control the charging and initiate the discharging; not the charger. So a simple, stable volatge supply should be all you need to charge them up.

Measurements. Done them on all previous DJI intelligent batteries, so no reason for the Air's to be different.
But you can even work it out from specs... The Mavic charger charges at 3.8A, but the car charger charges at 6.1A. If it was the battery doing the limitation that would not be possible.

Question - Are you thinking that either of the two chargers should work? I use the "blue one" and a clamp to battery inverter.
With car manufacturers skimping on wire gauge to save weight I don't trust the wiring harness to the cigarette lighter. I don't want an over-heating problem or fire in the car.

 

[Qoncussion]

Hard for me to say if that cigarette lighter version would work. That looks like a lot of load on whatever gauge wire the car manufacturer used for the lighter. I put a power inverter in my car, running a dedicated 4ga wire directly from the car battery to the 1100w inverter. I use the same charger as the one linked to in post #2.

has anyone try this charger as well?

i have read a lot of posts about using a power inverter is better, but i’m traveling overseas and would like to pack as light as possible.
i’m also worried about battery health .. any input would be apreciated

I bought this one -

I've only charged one battery at a time with it so far but it recharged a normal flight battery (30%) in about 40 minutes. I also charged a battery that went on an 'oh ****' run and returned below 10%, that battery took about 90 minutes to recharge.
