18v hoover freejet

[owas]

I found one of these at work,
Works fine, I just need to get a charger,
I don't want to pay genuine part prices, won't be worth it.

Is there a universal charger thing that would work,

Input - 23v 170ma .. it's like just smaller then a laptop charger plug

Mobility scooter charger might do the job if it's the voltage you're after.
