Important Tips:
The inverter is not a battery backup it is a conduit from the car battery to your electronic devices. This power inverter comes with a car cigarette lighter plug and a pair of alligator battery clamps, very convenient indeed for plugging into car's cigarette lighter port or connect it to your car battery directly, And easily changed by unscrewing terminals with fingers.
Please noted that the built-in fan would do starts run very slowly once flipped the ON/OFF switch to ON, even though under no loads. The fan has 4 gears of rotating speed can be self-adjusted by temperature and power loaded increasingly. This running fan slowly means the inverter is working normally because this new design is to avoid misunderstanding by some buyer's thoughts the inverter is not working or defective if the fan is not running or very quiet when powered and under no any loads. On the other hand, it also less too much noise with running fans slowly.
Be aware of your car's fuses(Most is 15A), most car‘s 12v cigarette lighter port is fused at 150W, due to the battery output voltage is 10-15V, then formula P=UI(150W=10V(Min) x 15A), so you won't be able to pull more than 150W if connect with car‘s 12V cigarette lighter ports; unless you plug directly into car's battery.
It also has an on/off switch which is nice because you can just flip the switch to shut everything down without pulling the socket, The ON-OFF switch only works for the 3-prong plugs. The USB portion is NOT switched that are always powered on so long as the power source is there. You can use the USB charge ports all of the time with NO LOAD from the inverter.
BESTEK 500W PURE SINE WAVE INVERTERS designed for your devices that require careful protection, Fully applicable for all appliances under 500Watts, great for a laptop, speakers, camera, nebulizer, game console, kindle, iPad and other.Great also for pumping up an air mattress when going camping/glamping.
This inverter device replaces all of the 12V extra stuff with the standard 120V chargers, The USB ports reduce the number of 12V items to ONE, all from a single 12V power outlet (cigarette lighter) in the car.it can be permanently installed within the car to power PlayStation or screens.
The fit and finish are excellent. You should check the amperage output of your car alternator to be sure that it has sufficient capacity over the running requirements of your car. Check your specs before using this with bigger wattage units.
It gives no noticeable evidence of RF interference. Runs a TiVo, TV (modest-sized - ordinary), and BIPAP w/humidifier all quite well. It is also relatively lightweight and comparatively small.
Be sure to unplug or turn it off when you shut off your vehicle as some vehicles still allow charging even when the ignition is off.
The Instructions of LED Indicator status:
1. Green Lighted——Working
2. Flashing Green——Under-voltage or Over-voltage Protection
3. Flashing Red——Overload Protection
4. Red Lighted——Short Circuit Protection
5. Flashing with Red & Green Alternately——Over-temperature Protection or Fan Fail to work
6. Off——Not Switched on,Fuse Blown or Not Powerred
- 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.

An essential part of my RV lifestyle while traveling or parked. I need a couple extra sockets for charging cell phones while driving our motorhome as all the charging ports are being used for other devices. It's also great around the garage for exercising my lithium RV batteries during storage in winter months. The Bestrk 500 watt 12 v inverter works great. I'm very pleased with the results of my purchase. Highly recommend.
