## Questions & Answers

**Q: Does this supply 500 watts through the cigarette lighter?**
A: Only technically yes, if your cigarette lighter can deliver 49 amps.  The cigarette lighter in our car is powered through the ignition switch and has a 10 amp fuse on it.  Those 10 amps at 12.6VDC translates to  about 100 Watts at 115 VAC out of the inverter.

**Q: How long will it power a modem/router?**
A: It depends on your power Source ... the Battery. But for a modem ... for a Very Very long time indeed :  ) I use it to power a mixing board for sound applications and it's Great for several hours using a small emergency battery intended for lights. The word EXIT might come to mind here : )

**Q: What is the no load power draw?**
A: If you put the power switch "ON" but don't connect to any electric appliance, the no load power draw is under 10 watts, generally  is around 7 watts. This power inverter has under-voltage protection, so you don't need to worry it will drain your battery off.

**Q: Will this power and run a 32 in tv with a cd player. Tv is led**
A: Some electronic device require pure sine wave AC. Or else ... smoke
