Ultimaxx Car Charger & Adaptor for DJI Phantom 4 Quadcopter Battery & Remote Controller

On-the-go charging for Phantom 4

This car charger and adaptor is built for DJI Phantom 4 quadcopter owners who need to recharge batteries and the remote controller between flights while away from mains power. It connects to a vehicle power source and supplies 17.5V at 4A for a 70W output. The unit charges both the drone battery and the remote at the same time.

Sustained charging behaviour

The adaptor delivers a full charge to both the drone and the remote in 90 minutes or less under normal vehicle voltage. A built-in fuse provides surge protection, guarding the connected equipment from spikes in current during extended charging sessions. The 70W output is maintained continuously while the engine is running.

Vehicle power interface limits

Operation requires a vehicle power source capable of supporting the 17.5V, 4A draw needed for the rated output. The charger is designed specifically for the Phantom 4 series and its remote controller; it does not support other drone models or battery types. Buyers who need to charge multiple battery packs sequentially or who lack a compatible vehicle socket cannot use this adaptor for those scenarios.
