According to the spec listed at Amazon, that dongle uses .75W or 62.5ma (at 12VDC).
That's higher than I'd like for long term use. If the battery isn't in really good shape and the weather is cold, I can see this killing the battery off, at least enough to keep from starting a car.
And that dongle isn't really designed for long term use. Plug it in, do you what you need to do, unplug it. It may not be convenient, but neither is a dead battery.
