BESTEK 500W Pure Sine Wave Power Inverter DC 12V to AC(2 Outlets) 110V Car Charger Plug Inverter Adapter Converter with 4.2A Dual USB Charging Ports, ETL Listed

## Features

- 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.

## Questions & Answers

**Q: how quickly will it inflate a queen sized air mattress?**
A: Its an inverter, not a compressor, so it will inflate your air mattress at the same rate that an overripe banana would... ie, it wont. It cant. So eat the banana and purchase an inflator.

Now, if you are using this inverter it to *power* an inflator, then the inflator will work at the same speed as it would plugged into a wall socket. But I’d still eat a banana because its clear you have a potassium deficiency (but I’m not a doctor so you may want a second opinion).

**Q: is this a three phase inverter?**
A: 500W Three Phase @ $60?  In what world is that?

**Q: I'll be attaching a relay on the (+) connector, so I'll keep the switch in the ON position all the time, is there a problem with this setup?**
A: Max power draw is very close to 40 amps (34-38 depending on battery voltage).  The relay would have to be a 50 amp rating MINUMUM, and higher if you can get it.  I believe the next common rating is 70 or 75 amps.

**Q: What size are the posts on the inverter? 5/16 or 3/8?**
A: It is neither. The posts on my unit are 3/16, which is adequate for the loop connectors and any load I'll be creating while using the unit.
