Feature: 1. 2000W HIGH POWER: Inverter provides AC socket for continuous DC to AC power output, with 5V 2.1A smart USB port, charging for most phones and tablets, while dual AC socket is perfect for laptops, charging pumps, lights, for iOS tablets, etc. 2. GOOD COOLING: The off grid inverter has an adequate cooling fan with a cooling aluminum alloy housing with multiple vents designed to prevent overheating. With infinitely variable speed and temperature control settings, the heat generated by the machine depends on the fan speed, which is really quiet and comfortable to work in a quiet environment 3. VARIOUS SAFE PROTECTION: Inverter adopt advanced isolation input and output technology design, safety is improved, with overload, low voltage, high voltage, overheating, short circuit protection function, more assured to use 4. INDUSTRIAL COPPER TRANSFORMER: Higher power conversion, more durable and stable than ordinary transformer, more robust output. Using industrial electronic components, the product application efficiency is higher, the performance is more stable 5. WIDE APPLICABLE: Both inductive load and resistive load of electrical appliances can be used, inverter is widely used in household appliances, vehicles, field work, industrial, office, tourism, etc. Specification: Item Type: Pure Sine Wave Power Inverter Material: Aluminum alloy and copper Output Power: 2000W Peak Power: 4000W Display: LCD Output Waveform: Pure sine wave Input Voltage(DC): 24V USB: DC5V 2.1A Output Frequency: 50Hz or 60Hz Working Temperature Range(rated): 32?H-104?H, 0??-40??
