I have a chinese one i bough like 10 years ago for 15$ maybe... I use it for football balls and inflatable pillow for camping... Once my tire was really down (Nail) so i inflated it fairly and went for repair...
For emergency, anything that blows air is good enough... i remember dad had a foot operated compressor
