【SMART CHARGING】Built-in intelligent MPPT charge controller chip helps to regulate the whole charging, generating at least 10%-20% more power than competitors. Smart 3-stages of charging algorithm is improved to better charge and maintain battery at a stable level for extended battery life..
【FULL PROTECTIONS】Prevent the battery from overcharge, over-voltage, discharge, and short circuit, reversed polarity protection, IP65 waterproof and spark-proof, the battery is fully protected. BEWARE OF SIMILAR CHARGERS WERE SIMPLY INTEGRATED A DIODE INSTEAD OF MPPT CHARGE CONTROLLER, IT WILL NOT PREVENT OVER CHARGE, WILL CAUSE IRREPARABLE DAMAGE TO BATTERY..
【EASY TO MONITOR】The LED indicator allows to visually monitor the working status and battery conditions. The charging will be cut off when battery is fully charged and resumed automatically when battery is drained, totally free maintenance..
【ROBUST & DURABLE】Made of durable and strong ABS frame instead of PVC fabric, which could withstand high temperature and UV irradiation. The tempered glass help solar cells to stand high wind and load pressure, Windproof and rainproof, well built for years. BEWARE OF CHEAPLY MADE ABS AND FABRIC SOLAR CHARGERS WHICH ARE EASILY DISINTEGRATED BY UV AND MAY CAT....
