Solar and Fast Car Charger DJI Power 1.8kW — Portable 1800W Charging Unit

The DJI Power 1.8kW — Portable 1800W Charging Unit is a solar- and vehicle-powered charger designed to deliver fast charging for compatible DJI batteries and other electronics within its power range. It accepts solar input and car alternator input, supports bi-directional charging and system expandability, and is intended for mobile use where reliable high-power charging is needed. The compact unit provides a practical solution for field work, travel, outdoor shoots and emergency on-board power.

Advantages

The charger combines solar and car charging inputs to achieve up to 1,800 W of total charging capability, enabling rapid replenishment of compatible batteries. It supports both 12 V and 24 V vehicle systems and features bidirectional charging to allow energy flow between connected batteries and vehicle power when required. The unit is lightweight and compact for easy installation in a vehicle or portable setup, and its performance characteristics make it suitable for adding significant onboard capacity during driving or while parked in sunlight.

Suitable for

• Field production and outdoor video/photo shoots requiring fast battery recharging
• Travel and overlanding where vehicle or solar charging is preferred
• Emergency backup power for compatible DJI batteries and electronics
• Mobile workflows that need expandable battery capacity and bi-directional power management

How to use

Install the charger in a stable location in the vehicle or portable rig and securely connect the provided cables. Connect solar panels to the MC4 input and the vehicle alternator to the XT90 input as needed; ensure the vehicle-side input voltage does not exceed the specified limits. Connect compatible DJI batteries to the SDC port for charging. Observe the specified input and output voltage ranges and avoid exposure to water or dust during installation and operation. Tighten terminal screws and secure wiring before driving to prevent loose connections.

Usage recommendations

Use appropriately rated solar panels and cables, and verify input voltages before connecting. Do not expose the unit to rain or heavy dust; operate within the stated temperature ranges. For extended high-power operation, ensure vehicle charging system and battery expandability are correctly configured, and follow manufacturer guidance for connecting additional expansion batteries to achieve higher total capacity.
