I have a couple of the Ring compressors, but to be honest, the other week I was in a hurry and grabbed the bike pump off the shelf. One of those high capacity, tall, standup ones with the T-handle you push up and down. It only took a few pumps and I was finished before I would have had the compressor unravelled and plugged in.
Ideal for a quick top up, but probably back-breaking on a flat.
