Guys I would like to buy a car Air pump to be used for emergencies. Can someone tell me of any good but economical brand ? Has anyone tried the "foot operated" pumps like the ones shown below : Foot air Pump Useful For Car, Bikes, Bicycles, Foot Ball Etc | eBay Are they effective ? Also I was seeing some pumps that can also double up as vaccum cleaners . Does anyone have any idea about the same ? Like the ones below : Coido 6022 2 in 1 Car Vacuum Cleaner & Tire Inflator Air Compressor Pump | eBay Thanks in advance for feedbacks!!
