Now wait a minute. DJI says the Mavic Air intelligent flight battery capacity is 2375 mAh. My Ravpower powerbank says its capacity is 23000 mAh. Even given charging losses, there should be at least five charges in there.
Only problem is, the Ravpower outputs at 9, 12, 16, 19, or 20 V. On one of these forms I read that the intelligent flight battery charges at 13.7 V. So one would have to figure out how to step down the voltage, or to be daring and discover that 12 or 16 will work anyway.
By the way, I've never seen an offering for a car charger. If it exists for the Mavic Air, could someone please post a link?
