Wee Banshee air pump
"The pump is wonderfully small and pretty lightweight. It is effective - it inflates a large air mattress in about 2 minutes. I have 3 criticisms, the third of which is minor. First, the accompanying User Guide is far from clear on which of the several nozzles to use for an air mattress. This also means that most people won't need 4 of the 5 nozzles provided. By trial and error, I found that the 15. 85 mm one ('For Air Pillows') is the one for the Highlander Nap-Pak Arctic mat. Second, the pump needs to be re-charged after only one use. So you need a means of re-charging it as well. Third, the pump is a bit noisy when inflating. Despite these comments, it's still worth buying."
