The unit supports three recharging methods: AC wall outlet (fast charge in approximately 1.5 hours), solar panel input (up to 200W, MPPT built-in), and 12V car charging. Safety is managed by an intelligent Battery Management System (BMS) that protects against overcharge, over-discharge, over-current, short circuit, and temperature extremes. The passive cooling design operates silently. The enclosure is made of flame-retardant ABS + PC material, with rubber corner bumpers for impact resistance. Dimensions: 35 x 23 x 23 cm. Weight: approximately 11 kg. Operating temperature range: -10°C to 40°C.
