Durable Aluminum Alloy Case Heatsink
The aluminum casing with a few ripples to suggest an actual heat sink surrounding a transformer,shock resistant,Compact design and anodized aluminum case.It has well placed thermal protection sensors, solid heat sink.
Built in Silent Cooling Fan
There is also a built-in FAN which comes ON under NO any loads or when the Inverter becomes hot.The fan has 4 gears of rotating speed can be self-adjusted by temperature and power loaded increasingly.Stays totally cool even after hours of use.The fan didn’t even kick on, nor did it overheat.
External replaceble Fuses
Two spare fuses included,the two 40A/32V fuses are ‘user replaceable’ commonly fuses and readily accessible/replaceable from the back of the Inverter.It is mainly used in high-power inverters (above 150W) equipped with car battery clips cable,which not only bears the function of built-in insurance, but also functions of reverse polarity protection.When the positive and negative poles of the battery clips cable are reversed, the diode inside the item is equivalent to direct conduction, which will generate a great current. At this time, the fuse is blown to prevent item damage. In this case, the user can still replacing the fuse with the same specification
Isolated Voltage Multi-protection
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.
DC to AC Pure Sine Wave Inverter
Pure sine wave inverter to protect your electronic devices and provide reliable power when on the move,it gives no noticeable evidence of RF interference.It produces very little EM noise, which is important if you run line level analog audio.Pure sine wave help electronics less wear ,kept sensitive electronics running smoothly to avoid the Modified sine wave inverters which tend to damage electronics.As a clean power source or an AC motor, laptops, and sound system to use.This vehicle inverter takes the guesswork out by providing a pure sine wave just like the power coming out of the outlets in your house.
Great Power Output Continuously
This adapter has two regular outlets plus two USB ports.the AC outlets easily powered a number of items that were under a total of 500 Watts.The ON-OFF switch only works for the 3-prong plugs.NOTE: the USB portion is NOT switched.the USB charge ports work fine too with it in the switch-off position so no fan noise issue for just charging usb gizmos, which detects your devices automatically to deliver its fastest charge speed up to 2.4 amps per port/4.2 amps max.Its main purpose is to provide 110 – 120V in the field for powering/recharging large tablets, high capacity battery packs, and a large telescope in the field, or on camping trips.
Connect with Alligator Battery Clamps
A power supply and battery serve as backup power into the inverter.To use it at much 150 above to 500 watts it needs to be connected to the car battery.The amperage draw is 0.005 A with the switch off and 0.3A with the switch on and under no load..So don’t leave it plugged in your car when it’s not being used.The battery clamps are very sturdy and resemble jumper cable clamps.Not a battery backup, this is a power inverter, you need a battery to run.
Connect with Cigarette Lighter Plug
This device is great as it plugs in where the cigarette lighter plug use to be handy,you cannot get 500 watts from 12volt car cigarette lighter, needs alligator clips for battery.It states it will not drain your battery dry because of an under-voltage protection point.The 12V cigarette lighter plug is spring-loaded and fits snugly into the receptacle.you’re going to be plugging this into your car or truck cigarette lighter, you should probably keep the wattage under 150, since that is what most car cigarette lighter fuses are set for.
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.
