Designed for both personal garages and professional workshops, this charger is compatible with all 12V and 24V lead-acid batteries, including AGM, GEL, Wet (Flooded), EFB, Calcium, MF, and deep-cycle models. Built with a durable metal frame reinforced by ABS housing, it is tough enough to withstand rugged environments while still portable at just 13.2 lbs.
Equipped with smart dual-mode charging, the charger automatically detects battery voltage and adapts its output for efficient performance. With a 0–15A range and support for batteries up to 400Ah, it provides fast charging to revive dead batteries or a trickle mode to maintain long-term battery health.

Cold weather can be tough on vehicle batteries, but the winter mode provides a full charge for reliable cold starts, while the all-weather mode adapts charging output to changing climates, ensuring consistent performance year-round. With its easy-to-read LCD display, you can monitor real-time charging progress, voltage, and current with precision.
For batteries struggling to hold a charge, the repair mode helps revive those that are weak but still above 3V. By delivering a controlled pulse charge, it works to restore functionality and extend usable battery life, getting your vehicle back on the road when you need it most.
Safety is central to the GEARLASSO charger. Built with pulse-based charging technology and multiple protections, it safeguards against reverse polarity, overcharge, overheating, overvoltage, overcurrent, and short circuits. A built-in cooling fan prevents overheating, while spark-free connections ensure safe handling every time.
