Lots of wattage to power stuff. Laptops need about a third of its rating, but the extra power is there if you want it, and you never know. It has 2 plugs so you could charge your cell and laptop at the same time. You can switch it on and off, too. This is a high end invertor so you pay a little more, but it gives you more at the same time.
Got this for my .5hp sump pump and it switched automatically without any stalling. Everything was as expected : shipping, undamaged and it works. It was raining and the ups guy even put a bag over it.
We have about 15 of these in use (all ordered from newegg). Absolutely top quality. After dealing with constant problems with other cheaper inverters/chargers we decided to go with these tripp lites. Regardless of the plastic body, they are very sturdy in the key areas. The manual VERY CLEARLY tells you the amount of torque required (3.5 newton meters) to secure the cables. They also say that insufficient tightening will void the warranty. Look at it like this, if it breaks then I can't imagine tripp lite not taking care of it. But I also can't imagine that if you tightened it properly you would have to worry about it breaking. VERY detailed manual. Although I wish it told you what size of hex wrench to use (7/32! I'll save you the hassle). We use these for mobile work stations that are in use 12 hours a day. We never turn them off, and have had one location using these for over 5 months now non-stop. For our application these are incredibly nice.
