Coleman Hand Pump is a great pump! Small and lightweight, yet durable to pack and take with you, can be used anywhere, as no electricity is needed.
This bike pump works on both the up and the down pump stroke, allowing you to pump up your item in half the time. This hand bicycle pump is optimally designed with a bore of about 3 1/2″ and a stroke of 12″, which combine to create about the right amount of air moved per stroke and input of muscular effort. The pump is all plastic, but is sturdy enough, and comes with four adapters, so you won’t have to worry about being without comfort or having to look for other accessories. Pumps fast and really easy. For less than $15 it is a good value.
