About this item

Product details

BESTEK 500W Pure Sine Wave Power Inverter

Designed to provide stable and reliable power for your vehicle, camping trips, outdoor activities, and emergency situations. This pure sine wave inverter converts 12V-17V DC battery power into 110V–120V AC power, delivering clean electricity for sensitive electronics such as laptops, cameras, speakers, CPAP machines, game consoles, and other small devices.

500W DC to AC Power Inverter with Dual Connection Options

This inverter includes a 12V-17V cigarette lighter plug and battery clamp cables, allowing flexible connection options. Use the cigarette lighter socket for lower-power devices or connect directly to your vehicle battery for higher power applications.

Pure Sine Wave Technology:

The advanced pure sine wave output provides clean and stable AC power similar to household electricity. It helps reduce electrical interference and provides safer operation for sensitive electronic equipment.

Optimal Use & Precautions:

• Designed for 12V DC vehicles only. Not compatible with 24V systems or aircraft use.

• This inverter is not a battery backup; it converts power directly from your vehicle battery to connected devices.

• Most vehicle cigarette lighter outlets are limited by a 15A fuse and typically support around 150W output. For higher power devices, connect directly to the vehicle battery using the included battery clamps.

• Do not leave the inverter powered on when your vehicle engine is off to avoid draining the battery.

• Keep the inverter away from direct sunlight, excessive heat, and moisture.

• Not recommended for high-power appliances such as hair dryers, heaters, or curling irons.

Package Includes:

1 x 500W Pure Sine Wave Power Inverter

1 x 12V Cigarette Lighter Plug Cable

1 x Battery Clamp Cable

1 x User Manual

2 x Spare Fuses

  • BESTEK 500W Pure Sine Wave Car Inverter:Its output waveform is same as the AC power waveform of mains power grid which delivers a smoothly-varying sine wave for sensitive electronics provided by the electric utility.Perfects for off-grid system,Lower THD,Less wear,Strong inductive Loads Capability.It has little interference with radios, communication and precision equipment.It's also recommended by most cordless tool manufacturer that a pure sine wave inverter is used to ensure long battery life
  • This is an inverter converting DC from your car battery to AC for whatever you want to use within its Watt range.It can pull power from the battery through the cigarette lighter plug or directly clamp the alligator battery clips onto the car battery.Plug this into 12v cigarette lighter outlet provides continuous DC to AC power with 2 AC outlets operates any 110v device and 2 USB ports which detects your device automatically to deliver its fastest charge speed up to 2.4 amps per port/4.2 amps max
  • The Sine Wave Inverter has well placed thermal protection sensors,The aluminum alloy casing with a few ripples,Unique vents and also a built-in FAN which comes ON under NO any loads or when the Inverter becomes Hot Once Powerred. It has 2 x 40 amp/32V external replaceable fuse for protection when hooked up to your battery,readily accessible/replaceable from the back of the Inverter;when hooked to cigarette lighter it will use 15 amp fuse designated to your car.
  • Isolated Voltage Protects Perfectly for your device from Over-voltage,Under-voltage,Overheat,Overload,Reverse Polarity,Short circuit.it will not drain your battery dry because of an under-voltage protection point.The Inverter does automatically sense overload condition and shuts down AC power when the load exceeds 500W.You will need to power Off/On to reset the overload condition indicated by the Flashing Red.The ON-OFF switch only works for the 3-prong plugs.
  • The 12V plug is spring-loaded and fits snugly into the receptacle.You cannot get 500 watts from 12volt cigarette lighter plug,needs alligator clips for car battery. If you're going to be plugging this into car cigarette lighter,you should keep the wattage under 150,since that is what most car fuses are set for.What You Get:1xBESTEK 500W Pure Sine Inverter,1xUser Manual,2xbattery clamps cable,1x 12V cigarette Lighter plug cable,2 x spare fuses.

Powering a Nebulizer

The BESTEK worked without flaws. I purchased the machine to provide the power to administer a Nebulizer to the person in the back seat of my vehicle during long trips. The BESTEK had the power necessary to to do the job without having to any power interruptions or uneven power. The BESTEK is easy to set up and operate.

It's the first time buyer of a pure. Sign wave inverter there was a lot of hesitation an uncertainty about Whether or not it was gonna fit be enough operate safely But since I've had this thing installed, and it's been a few months now. I regularly charge a gaming laptop on it. And run a gaming laptop on it. And have since used a heat gun while working on my vehicle. With no issues whatsoever to power load or anything I just wanted to say It's one of the best investments I've ever made.
