This STARTRC battery charger hub integrates smart functionality, efficient charging, and comprehensive safety: it features two core modes—Storage Mode (long-press power button to charge to 60% for long-term storage, auto-stops to prevent overcharging/discharging) and Full-Charge Mode (charges to 98–99% then cuts power to extend battery life, indicated by a green light). It enables rapid charging (3×2453mAh batteries in ~135 mins, 3×3850mAh in ~195 mins) in descending order of battery level, with upgraded circuitry for stable output in extreme conditions. It also has 8-layer protection (guards against over-current, over-voltage, etc.) and a real-time LCD display showing voltage, current, battery level, and temperature per slot. A DJI 30W USB-C/PD fast charger (not included) is required for max efficiency.

Exclusively compatible with DJI Mini 4 Pro, Mini 3, Mini 3 Pro, and their Intelligent Flight Batteries (2453mAh, 3850mAh) — it charges all compatible batteries in one hub, eliminating multiple chargers (note: not for Mini 2/Mavic Mini). Ideal for scenarios like seasonal battery storage (Storage Mode aligns with DJI’s lifespan recommendations), high-altitude flights (auto-detects battery type for stable charging), and daily use by drone pilots needing efficient, safe charging while monitoring battery status in real time.
