About this item

  • 【TRUE 20-AMP COMMERCIAL GRADE POWER】 Engineered for heavy-duty performance, Haisito delivers a massive 20A (12V) / 10A (24V) output, charging batteries 40% faster than older generation 20A chargers. Ideally designed for pickup trucks, SUVs, RVs, boats, and farm tractors. Why wait for outdated technology when you can power up instantly?
  • 【UPGRADED HD SCREEN & VISUALIZED CHARGING】 Struggling to read dim screens on sunny days? We solved it. Our newly designed High-Definition LCD Display provides crystal-clear visibility day and night. Real-time monitoring of charging current, voltage, battery status, and internal temperature gives you total control at a glance.
  • 【AI-SMART CHIP FOR LITHIUM (LiFePO4) SAFETY】 Stop using "dumb" chargers that damage your battery. Haisito features a Next-Gen Microprocessor that precisely detects battery chemistry. It offers optimized charging curves specifically for Lithium-Iron Phosphate (LiFePO4), AGM, Gel, SLA, and Wet batteries, ensuring 100% full charge without over-voltage risks.
  • 【REVIVE DEAD BATTERIES WITH PULSE REPAIR】 Don't throw away your aging batteries. Our advanced High/Low-Frequency Pulse Repair technology removes sulfation and acid stratification, restoring lost performance for stronger engine starts. (Note: This is a professional CHARGER/MAINTAINER, not a jump starter. It cannot activate totally dead batteries with 0V).
  • 【ALL-WEATHER PROTECTION & THICKER CABLES】 Built for the garage environment. Features a built-in temperature sensor that adjusts charging based on ambient heat or cold. Upgraded with Industrial-Grade Pure Copper Cables and heavy-duty clamps that stay cool and secure, solving the overheating issues common in generic chargers.
