Was looking for some extra batteries and found this. I have the power source and use it to charge electronics when the power goes out. It's handy. The power source is about $30. The vac is about $40 and the light is about $40. Can't speak to how good those are, but it's like buying two batteries and a charger and getting three free tools.
