Electric tire inflators
Which cordless inflator, when both publish their numbers?
These two publish more than the rest of the category put together, which makes this the one comparison in this hub that can be settled on figures rather than on impressions.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
The one that tells you what it weighs and what is in it. Four hundred and thirty-nine grams and 4000 mAh are two figures nobody else in this hub publishes, and a motorcycle preset alongside car, bicycle and ball makes it the broader household tool.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
The most completely documented product in this hub, and the figure that decides it for bicycles is the 0.2 bar floor — the lowest here, and what makes it usable on a wide mountain bike tire where units with a higher minimum bottom out. A published noise figure is unusual and welcome on a device used in a flat.
The lowest preset, not the maximum. Every inflator here reaches far beyond any bicycle pressure; what varies is how low it can be set, and a wide mountain bike tire lives around 1.8 to 2 bar.
Both ship with adapters. The Presta adapter is a small brass fitting that screws on, and it is the piece that gets lost — the Bosch in this hub stores its adapters inside the handle for exactly that reason.
Loud enough to be unpleasant indoors and brief. It is the only noise figure published in this hub, so there is nothing to compare it against here — treat it as information rather than a ranking.
