Purchased for a remote location with only solar power and a large deep cycle marine battery for energy storage in the middle of the desert. This stock has withstood high and very low temperatures. In the place where it is located, there was a strong wind that destroyed the solar panel. The weather monitoring system at this remote location is a DC powered device that does not consume much battery. I've used this laptop DC power supply and not as much as you might think. I checked the battery voltage and it has never dropped more than 0.2 volts with each use, which is about 45 minutes on average. As soon as new solar panels appear, energy consumption no longer plays a role. All in all, this is a great solution for powering your laptop remotely or in the car.
