Why we love it
  • Pure sine wave offers reliability.
  • Multiple charging options available.
  • Safety features for peace of mind.
Main Highlights
  • 500w Pure Sine Wave Power Inverter: Converts DC power from your car battery to AC power, delivering a smooth sine wave ideal for sensitive electronics. 500w pure sine wave inverters perfects for off-grid systems, lower THD, less wear, and minimal interference with radios, communication systems, and precision equipment. A pure sine wave inverter is recommended by most cordless tool manufacturers to ensure battery longevity.
  • DC 12V to 110V 4.2A (2 USB+2 AC): The inverter converting DC power from your car battery to 110V AC power suitable for devices within its wattage range. You can employ either the cigarette lighter plug or the alligator battery clips for connection. Plug the sine wave inverter into 12v cigarette lighter outlet provides continuous DC to AC power, offering 2 AC outlets for any 110V device and 2 USB ports, which detects your device automatically to deliver its fastest charge speed up to 4.2 amps max
  • Built in Cooling Fan & Replaceable Fuse: The inverter features strategically placed thermal protection sensors, an aluminum alloy casing, and distinctive vents to provide effective heat dissipation. Additionally, there is a built-in fan that kicks in when there is a load or if the inverter's temperature increases. The external replaceable fuses (3 x 40A/32V) are designed to provide protection and are easily accessible from the inverter's rear when connected to your battery.
  • Isolated Voltage Protection: With isolation voltage protection, offering comprehensive safeguards against over-voltage, under-voltage, overheating, overloading, reverse polarity, and short circuits. Importantly, it prevents excessive battery drain due to under-voltage protection. Automatically sensing overload conditions, the inverter halts AC power output when the load exceeds 500W, requiring power off/on to reset the overload condition, indicated by a flashing red light.
  • Dual Connection for Inside/Outside Car: The spring-loaded 12V plug needs to securely fit into the receptacle. You cannot get 500 watts from a 12V cigarette lighter plug. To achieve a 500W output from a 12V cigarette lighter plug, alligator clips are necessary to be attached to the car battery. When using the cigarette lighter, it's recommended to limit the wattage to under 150W, which is in alignment with most car fuse ratings.
  • With your purchase, you'll receive the vansoet 500W Pure Sine Wave Inverter, a user manual, two battery clamp cables, a 12V cigarette lighter plug cable, and three spare fuses.
