The good part:Decent build and high quality plastics used. I have used it to power 8W rated Honeywell Move Pure Car Air Purifier (Bold Black) and it managed to run forever without any issues. No heating or any other glitches.The bad part:I tried to power a small tire inflator and it managed to work for about 10 minutes it took to fill about +5 psi in two tires After that it would just supply power only in quick pulses and I could not use the tire inflator. I am sure that the tire inflator is rated below 72W as it is a very small one compared to what you get in the market and takes forever to fill air. There is no damage to the convertor or the inflator, just that it is not able to power it. I also tried to run the 12.5W rated Black & Decker ACV1205 12 Volt DC Cyclonic Auto Dustbuster Car Vacuum Cleaner (Gray), this also didn't work as the power came only in pulses.My conclusion: It works reliably and very durable as long as the devices you run are rated much lower than their claimed 72W. How much lower? I don't know. It worked for 8W rated air purifier but failed to run 12.5W rated vacuums cleaner and tire inflator of unknown rating. Luckily my primary purpose for buying it was to run the air purifier when the car is parked in the garage so I am happy with the purchase.   Read Less
