Phantom 4 Pro charger power consumption?

[Ben01]

Hi everyone,

I’m looking at purchasing a portable lithium power pack to charge my drone batteries and RC while travelling.

I’m completely illiterate when it comes to all things electrical so I was just wondering what sort of power does the genuine dji car charger use? My car charger is the single battery charging unit for p4p - does not charge two batteries at once.

The unit I’m looking at is a 21.5ah (see pic) which also has an inverter for AC use but I have no idea if it would be better to charge with that or via the 12v socket. I have both standard AC & car charger.

Just wondering if anyone could maybe tell me roughly how many battery charges I’d get out of this?

Many thanks for any advice.

Standard P4Pro batteries are rated at 5870mAh (5.870Ah). Typical use will take them to half that amount so you will have to add roughly 3000mAh (3Ah) to fully recharge. This unit could feasibly recharge 6 to 7 batteries. The AC outlet would likely charge a pack faster, but the 12V outlet may be more efficient (less loss to charging units).
