I might get a 2nd one.
Simple, affordable, and reliable for powering lights and such in our backyard shed. Very pleased with how its helped my use some 12V batteries.

Stanley Inverter Review.
Handled the load that I put on it with my CPAP machine while camping. Fan is a little loud, but then so is my CPAP machine. The first night it shut off after about four hours and had a flashing power button light and I could not find anything in the instructions that identified this issue, but it did not happen again the next two nights that I used it.

New is great but don't ever lose any cords.
I do very much like having this outlet available for emergencies and for attempts at camping. The only downfall I have with it is I purchased this entire thing again because I could not find the cord to link it to the outlet in my vehicle, nor could I find the cord sold anywhere. Walmart shows it online but it says unavailable. So as long as you don't lose the cord, this gadget is great.

Not enough to charge a laptop.
This did not work to power my dell precision laptop. It also quite large. I ended up purchasing the EverStart 400 Watt Inverter and that has worked great.

Purchase something else
Not able to produce the advertised wattage, always says orver load on devices that work fine on other lower wattage inverters. Keep it as a backup but don't trust it.
