When the pump's out of order.
Low-pressure light at 11pm, every gas-station air machine closed.
What matters most — It comes down to how fast it airs up, and whether the battery outlasts the job.

Questions worth answering first
Straight answers to the things that actually change which one you should buy.
A good cordless inflator tops a car tire from low to full in about a minute. Starting from flat takes longer, and truck, SUV, and higher-PSI tires take proportionally more time and battery.
Cordless (Li-ion) is the convenience pick — no cord, and it works away from the car. A 12V corded unit never runs out of battery on a long job but tethers you to the outlet. Some units offer both.
Car tires run about 30–35 PSI, and most inflators max out at 120–160 PSI — far more than a passenger tire needs. If you air up truck, RV, or trailer tires, check the max PSI and the duty cycle.
Small pocket inflators are best for topping off a slow leak; inflating a fully flat tire strains them and drains the battery. For real flats, size up to a unit with a bigger battery or a 12V fallback.
