Product Information

As for reliability, I've used this numerous times over the last 12-18 months (occasionally multiple times I one day) it's still going strong. This allows for a smoother airflow, which in turn creates an even down force along the entire length of the blade.

You can also inflate bicycle tyres and inflatables such as paddling pools using the adaptors supplied. Under this skin is the steel sub-structure which provides a sturdy support for the rubber wiping element. Replacing the refill too many times should be avoided, as the wiper blade superstructure will become weaker over time. Simple pre-set the pressure you need, attach the air hose fitting to the tyre thread and turn on the unit.I would recommend this to those who have strong enough fingers and wrists, but I'm afraid it's not for me. In the event of a puncture whereby you might have to use some tyre sealant, inflating them back up is next. It needs to be greater than what you are trying to inflate otherwise it won’t be able to reach the desired pressure.

According to the product specifications it should inflate to 100psi but when I tried to get my caravan tyres to 85psi it just died.The AA tire-pump works fine … so far (others have had problems - see their reviews below) and it fits very neatly in our oldish Yeti boot - the Yeti now starting to have those well-known/infuriating alloy-wheel air-leakage problems.
