Quick USB Charging With 2 Smart USB charging port, can auto detect your devices and deliver best matched charging current to get fast charging speed.Auto 0-2.4A each port, total 5V 4.8A output. Easy to Use Method 1: Connect with Alligator Battery Clamps This connecting way can provide you max 500 watts continues 110v AC output. When your vehicle battery voltage is under 11V, it will trigger input under-voltage protection and avoid to drain your vehicle battery. Method 2: Connect with Cigarette Lighter Plug This connecting way can provide you max 150 watts continues 110v AC output. Why the output is less than 150W ? Because the circuit limitation of most vehicle cigarette lighter socket fuse is LESS than 10A, if the max input DC voltage reaches 15V, then the max AC output from inverter is around 150W.(P=U*I) If you need more power output,please connect the inverter to vehicle battery with the 2 clamps Directly. External Replaceable Fuses Built in 2*40A Replaceable fuses , protect your device from over-current, over load damage. 2 pcs of spare 40 amps fuses is included in package. Cautions This is a Modified Sine Wave Power Inverter, applied for DC 11V - 15V, not for DC 24V. Due to the fuse protection of vehicle cigarette lighter socket, the AC output can reach up to 150W when you connecting it with cigarette lighter plug. If you need the max 500W power output, please connect it to the vehicle battery with the clamps Directly. The cooling fan is quiet and smart, will rotate at different speed according to the power load and temperature inside.So don't worry if the fan doesn't come on while the power load is low. Do not leave the power inverter at the ON position for long time while your car is off.

The cigarette lighter in our car is powered through the ignition switch and has a 10 amp fuse on it. Those 10 amps at 12.6VDC translates to about 100 Watts at 115 VAC out of the inverter. **Q: How long will it power a modem/router?** A: It depends on your power Source ... the Battery. But for a modem ... for a Very Very long time indeed : ) I use it to power a mixing board for sound applications and it's Great for several hours using a small emergency battery intended for lights. The word EXIT might come to mind here : ) **Q: What is the no load power draw?** A: If you put the power switch "ON" but don't connect to any electric appliance, the no load power draw is under 10 watts, generally is around 7 watts. This power inverter has under-voltage protection, so you don't need to worry it will drain your battery off. **Q: Will this power and run a 32 in tv with a cd player. Tv is led** A: Some electronic device require pure sine wave AC. Or else ... smoke ## Customer Reviews ### ⭐⭐⭐⭐⭐ Unit turns off after a period of time *by D***L on May 9, 2026* This one was working fine for 3days then it started turning off some time during the night.
