About this item

  • πŸ”‹ 【2-in-1 Charging & Repair】: this konnwei rc-10 combines a 12v 10a / 24v 5a smart charger with pulse repair technology, suitable for lead-acid batteries (agm, gel, sla, flooded, efb) and lifepo4 lithium batteries. it’s designed for 4ah-150ah batteries in cars, trucks, suvs, motorcycles, boats, lawn mowers, and marine equipment, offering both fast charging and battery restoration in one device.
  • ⚑ 【7-Stage Fast Charging】: the 7-stage charging process includes desulfation, soft start, bulk charging, absorption, battery test, reconditioning, and float maintenance. compared to 8a chargers, it delivers up to 30% faster charging speed while automatically adjusting voltage and current to protect battery health. ideal for users needing rapid charging without compromising battery lifespan.
  • πŸ”§γ€ Advanced Repair】: using pulsed voltage and current, the charger detects and repairs sulfation and acid stratificationβ€”common issues that reduce battery performance. this technology revives lost capacity, extends battery life by up to 50% and is perfect for reviving deep-cycle batteries in marine, rv, or automotive applications where battery longevity is critical.
  • πŸ›‘οΈγ€ Built-In Safety Protection】: built with arm architecture pcb, the charger offers overheat, overcurrent, reverse polarity, and short-circuit protection. its fireproof abs housing, silent cooling fan, and double relays ensure safe operation even after 72+ hours of continuous use. certified by ce/fcc/rohs, it meets global safety standards for reliable performance.
  • πŸ”Œγ€ Easy to Use, Wide Compatibility】: simply clamp the red/black leads to the battery (positive/negative) and plug into 110-220v powerβ€”the charger automatically identifies battery type and voltage. suitable for both 12v and 24v systems, it’s perfect for DIY users, mechanics, and vehicle owners who need a portable, all-in-one charging solution for various equipment and vehicles.
