Would that hole be ready to accept one of these?:

Car Charger 17.4V 4A for DJI Phantom 4 / 4 Pro RC Quadcopter N5E0 | eBay

Car Charger Kit For DJI Phantom 4 Pro & Adv 1 Battery 1 Remote Outdoor Charging | eBay

What is reason for adapter in latter? (am in US)

What is ratio of simple up-down (flight time / charge time) via car?
For every 10 minutes of charging, ? minutes of flight...?
thanks.

Your hole looks like a standard cigarette lighter outlet and should be ready to accept the two units pictured. But I wouldn't buy those because of what they list as their rated power output.

I have this which has higher output specs: Buy Phantom 4 Series - Car Charger Kit

I haven't timed how long to charge yet because I usually use when going between flying sites. I have not tried to use with an idling vehicle.

Thanks for advice!
Am not electrician.
How would you describe difference in your power
output vs. these cheaper versions? Does twice the
power output mean half the time to fully charge? Or?
How much longer for these cheaper versions...?

More power generally means shorter time to charge depending on the battery (number of cells, capacity, etc.), ambient temperature during charge, etc., <warning> BUT <warning> too much power can cause problems, especially with LiPo batteries. That's a pretty easy way to start a fire.

DJI specs:
Product Model: C4S90-4
Operating Temperature: 32° to 104° F (0° to 40° C)
DC Input: 12.3-16 V (Sedan); 25-30 V (Coach)
DC Output: 17.4 V; 5.17 A; 90 W
Charging Time*: 1 hr 10 min (Intelligent Flight Battery)
3 hr 20 min (Remote Controller)

The only way the first unit (4A; 72W) is going to charge a battery in the 80 minutes advertised is if the battery is likely more than 50% charged to begin with.

And the second unit (3.5A; 61W (calculated)) is even worse.

Do you really want to charge a $125 - $160 battery with a $15 charger with exaggerated charging time claims?
