About this item

  • 12A Efficient charging for 12V & 24V: Upgrade your charging experience. Delivers a steady 12A output for 12V batteries and 6A for 24V batteries, charging 2x faster than standard 5A or 6A trickle chargers. Designed for a wide range of vehicles including Cars, Motorcycles, ATVs, RVs, SUVs, and Boats. Automatically detects voltage and switches to the appropriate mode.
  • Smart compatibility (LiFePO4 / Lead-Acid): Versatile enough for the whole family. Features specialized charging modes for 14.6V LiFePO4 Lithium batteries and all types of Lead-Acid batteries including AGM, GEL, SLA, Flooded (WET), and EFB. Whether it's a modern lithium battery in your motorcycle or a standard battery in your sedan, this charger covers your needs.
  • Pulse Repair & Battery Health: Don't let old batteries die. The built-in Repair Mode uses high-frequency pulse technology to remove sulfation from battery plates, helping to restore performance to old, idle, or stratified batteries. An essential tool for maintaining battery health during long-term storage or winter inactivity.
  • LCD data display & Temp compensation: The clear LCD screen cycles through charging voltage, current, temperature, and battery percentage, keeping you informed. Built-in sensors detect ambient temperature and automatically switch between Winter Mode (boosting voltage in cold) and Summer Mode (preventing overcharge in heat) for optimal charging in any weather.
  • Multi-protection & Plug-and-play: Engineered for safety. The smart chip provides comprehensive protection against reverse polarity, short circuits, over-current, over-voltage, and over-heating. Simply connect to the battery (Red to Positive, Black to Negative), plug into an outlet, and select your mode. It stops automatically when the battery is fully charged.
