Overview
A driver or cyclist gets a corded inflator that runs on DC power, shows pressure on a big twin-display screen and stops by itself at a preset value. A memory function recalls the last setting.
Preset, auto-stop and memory make repeated fills simple, and the longer power cord and hose are advertised as a feature. The capacity entries in the listing are odd, giving one figure for both capacity and tank volume, so airflow is the useful number. Power is corded only.
Who it's for
Car owners and cyclists who keep an inflator in the trunk and want a preset target will use the screen and memory. Anyone inflating away from a DC supply, or needing a hose that reaches across a large vehicle, should look at other options.
Pros and cons
- Preset pressure with auto-stop
- Dual digital screen
- Memory of last setting
- Carrying bag and valve adapters included
- Hose is short
- Corded power only
- Capacity entries look inconsistent
Performance notes
Fill speed follows airflow and the motor's power draw, so larger tires take longer than a bike tire. The pump stops once the preset pressure is reached, which relies on the digital sensor reading. The motor draws its current from the DC supply, so a weak connection slows the fill.
