File this under “stuff that makes sense” and drop a carbon copy in the “why didn’t I think of that” folder. This is an in-vehicle power inverter with two AC outlets and a USB charging port in the shape of a coffee cup so it’ll fit perfectly in your car’s cupholder.
It’s only $30, too, which isn’t insanely expensive for a power inverter — especially one that fits somewhere like, for instance, a cupholder. The “Powercup” puts out 120 volts of AC power (200 continuous watts), which should be enough for most laptops along with your cell phone and one other gadget.
