I have this set (actually two of them). It is very useful for the small handheld vacuum as you can mount the charging base to a wall (probably the only useful use). I was planning to use it for my impact driver, but the 2Ah wireless battery is about the same size and weight as my 4Ah regular batteries.



The fact that you have to be careful with steel tools around the charging base makes me nervous, so I don't leave it out on the workbench. With the holster the wireless charging is ideal for in a work van.



There are 12V wireless batteries as well, but i have never seen them in Canada. They could make a lot of sense for assembly work with a small impact driver.
