Fanttik X8 APEX
Pros
- Very light at 1.74 lb
- 150 psi rating
- USB power-bank output
- Relatively quiet
Cons
- Struggled on a truck tire
- Very short hose
- No 12V or AC adapter

A good top-off pump for passenger cars. It is not an all-purpose inflator, but for a compact glove-box tool at a modest price it does the job.

Pros
- Fastest in Outdoor Life's truck-tire test
- 150 psi rating and four memory presets

Cons
- Sold without battery or charger

The best choice for anyone who wants a fast inflator for large tires, especially if M18 batteries are already on the shelf. It costs more once you add a battery, and it is bulky, but nothing else here has stronger measured results.
