For inflation I use this Ryobi product
www.ryobi.com.au/products/air-inflators/18v-one-inflator-deflator-tool-onlyI have to gerry-rig two hoses to connect to my Duotone, but I will fix that one day.
I just use the inflator to get close to the right pressure then quickly switch to the Duotone hand pump to get it exact.
While it can't be trusted on the exact pressure for the wing, I trust it to get the pressure right on my car tyres.
So if you have other 18v one products I recommend it.
