Sealey 12V Mini Compressor

If all you need is a simple pump, this cheap and cheerful Sealey could be for you.

The unit added only 5psi to our tyre in 60 seconds, and the gauge is difficult to read – but it was accurate at 20psi and only 2psi out at 30psi.

You have to wrap the lead and hose around the pump, and will need to find somewhere safe for the sports adaptor, although the two leisure adaptors can be clipped to the airline.
