12V to 220V Power Inverter and Solar Kit, Black Key benefits Provides a compact, portable AC power solution from a 12V battery for camping, road trips, offgrid work, and emergency backup. Converts vehicle or battery DC power to household AC power and dual USB charging, so small appliances and electronics can run where mains power is not available. Builtin protections and cooling keep the system safe and reliable during use. Main features Output power: 300W continuous, 4000W peak. Ensure total connected load does not exceed 300W. Output voltage: selectable 110V or 220V with a tolerance of plus or minus 10 percent; frequency 50Hz or 60Hz. Input voltage range: 9.5V to 15.5V. Low voltage protection: 9.5V. voltage protection: 15.5V. Noload current: 0.7A or less. USB charging: two ports, each 2.1A for charging phones, tablets, and other USB devices. Conversion efficiency: up to 90 percent. LCD digital display shows battery status and alerts for undervoltage, overvoltage, overload, temperature, and short circuit. Cooling fan and builtin fuse for thermal management and overload protection. Solar and charging components Solar panel: 18W, 18V specification included in the kit. Solar charge controller: 30A capacity with automatic recognition of 12V or 24V battery systems. Supports charging and battery maintenance when paired with the included solar panel. Compatibility and applications Compatible with 12V vehicle batteries and 12V or 24V battery banks when using the solar controller. Suited for small AC devices and electronics such as laptop chargers, phone and tablet chargers, LED lights, small fans, and audio equipment within the 300W continuous limit. Typical use scenarios: Camping or RV trips: power lights, charge phones and tablets, run small appliances at a campsite. Roadside or vehicle use: power devices from a car battery using the included cigarette lighter adapter or battery clips. Emergency backup: run essential small electronics and charge mobile devices during a power outage.
