I read reviews on several lower priced third party chargers and was very concerned that cheaper chargers would damage my batteries and controller for me, it’s not worth the risk. I will stick with genuine dji accessories for my mavic drone. This car charger does the job without damaging my expensive batteries. Nice product don’t buy a knockoff, will fry a battery and these things cost 115 a piece disappointed. This didn’t come with a fly more combo and that it’s 60 dollars extra, but it’s a must have i road trip a lot in florida, and this is perfect. You can just connect it to the hub charger and charge all batteries at once. Also good. If it happens that you forget to charge your batteries and have to charge them on the go like i said, it’s a must have.
