About This

• 5-in-1 Multi-Function Unit: Charger, Jump Starter, Maintainer, Battery Repairer & Desulfator. Handles daily charging, long-term storage maintenance and aged battery revival, replacing multiple single-purpose tools to cut costs.
• Efficient, Energy-Saving, Fast Charging: The battery charger automatically recognizes battery voltage(12V: 8A/15A/30A, 24V: 4A/7.5A/15A). The maximum charging current is 30A, capable of fully charging a battery in a short time to meet your different needs. It not only saves energy but also saves you a lot of waiting time.
• Engine Start & Winter Modes:130A surge current cranks vehicles in 3s to revive flat batteries. Winter Mode boosts charging for cold batteries for full replenishment.Safety Note: It won’t charge/jump-start batteries under 1V; built-in safety cutoff protects the unit and users.
• 7-Stage Automatic Charging Cycle: Detection → Pulse Desulfation → Fast Charge → Trickle Charge → Recheck → Float Maintenance → Absorption Charge. Zero manual operation revives damaged batteries and avoids harm from over/undercharging.
• Complete Multi-Layer Safety System: Reverse polarity, short-circuit, overcharge, overheat, overvoltage and overcurrent safeguards prevent miswiring and detect faulty batteries. High-power cooling fan and 120°C heat-resistant clamps deliver stable long-duration high-current operation.
• Wide Compatibility: Fits 12V/24V lead-acid batteries (STD, AGM, GEL, MF, EFB, Calcium & deep-cycle) for cars, boats, RVs and power sports.
