【Exclusive Hardwired Structure + Dual Universal Outlets】The transformer’s 3000W+ power is achieved via hardwired connection; equipped with 2 universal outlets for low-to-medium load devices, outlet total load limited to 3000W maximum to ensure stable safe operation. Power cables are NOT included for customized wiring installation 【6000W Step Up Voltage Converter】Converts standard US 110V/120V input to stable 220V/240V AC output, no step-down function, perfectly matched for imported European & Asian EV chargers and 220V heavy-duty appliances.【Weight: 30lb】 【Heavy-Duty Industrial Grade Build & Wide Application】Thickened pure copper winding core delivers steady voltage output with low energy loss; ideal for imported 220V power tools, kitchen machinery and other high-power 220V equipment on North American 110V grid. 【Cooling Fan Heat Dissipation System】Built-in high-speed cooling fans actively expel heat during long-hour high-load work, effectively lower internal temperature, reduce coil aging and extend the transformer service life for continuous EV charging tasks. 【Safe Power Matching Standard】For safety reasons, it's recommended to use a Voltage Converter / Transformer that's max watts is at least 50% higher than your appliance. 【Resettable Circuit Breaker Safety Protection】Automatic power cut triggered by overload, short circuit or overheating; resettable breaker avoids frequent fuse replacement, fully protects the transformer unit and your equipment.
