Stronger? Which one? I bought one for 30 bucks and it was extremely loud and had less blowing power than the can. As I buy 1 can every 5 years or so, I returned the electric one.
I have a micro inflatable mattress fan that I use to clean my keyboard. It has attachments and one of them is just a tiny small pin hole, I think it's meant for inflatable water donuts or something. Works wonders.
