I've been happy with a two stage 12v Bravo running from a small battery for over a decade now. Never felt the need to try another type or run a second pump like some folks as the Bravo turbine output is very high anyway.
The other day though I decided to meet an intermittent need for a good blast of air in my varied DIY work and saw this Ryobi battery air blower on a Facebook Halfords promotion. As I have other Ryobi power tools and hence a battery to suit it was just £29.99 compared with a daft £90ish with battery.
Looking at the outlet nozzle thought I wonder... and yes indeed it is the correct size for Zodiac/Bombard valves such as in the Aerotec. Plugs directly into the HP floor and also into the standard adaptor for the tubes.
It would be purely for initial filling as it only reaches 0.5psi but the output is great at about three times the Itiwit and 10% more than a Sevylor. It'll be interesting to give it a go first time out filling other chambers as the Bravo works away.
