Feature: 1. [AC Socket and USB Port] 2000W pure sine wave power inverter has two AC sockets for charging small equipment or home appliances, and one 5V 2.1A USB port for charging most mobile phone and tablets. 2. [Good Heat Dissipation] Multi vent aluminum alloy housing and built in cooling fan of the power inverter provide excellent cooling performance to prevent the device being over heating and damaged, real quiet. 3. [Safe Use] The inverter is designed with advanced isolated input output technology, improves its safety, has the protection functions of overload, low voltage, high voltage, overheating and short circuit, more safe to use. 4. [Excellent Components] The red copper transformer has higher conversion power and strong output. Industrial electronic components ensure higher efficiency and more stable performance. 5. [Wide Application] Both inductive and resistive load electrical appliances can be used. The inverter can be widely used in household appliances, vehicles, field operations, industrial, office, travel, etc. Specification: Item Type: Pure Sine Wave Power Inverter Material: Aluminum Alloy, Red Copper Output Power: 2000W Peak Power: 4000W Display: LCD Output Waveform: Pure Sine Wave Input Voltage (DC): 12V USB: DC5V 2.1A Output Frequency: 50Hz or 60Hz Working Temperature Range (Rated): 32-104?H, 0-40??
