Our verdict: ✓ KEEP

Research supports the X8 APEX for drivers who want a small cordless inflator for topping up car tires and other compatible inflatables. Its 150 PSI maximum, built-in display and automatic stop at the set pressure make roadside top-ups simple.

What it does well

Sets pressure in PSI, BAR or kPa, offers preset modes for car, motorcycle, bicycle and ball inflation, and stops automatically when the selected target is reached. Fanttik lists a USB-C charging input and USB-A output for small-device charging.

Who it is for

Drivers who want a compact, rechargeable backup for routine pressure corrections and occasional roadside use.

Who should skip it

Anyone who regularly inflates several large tires, needs a replaceable battery, or prioritizes the fastest fill time should compare a larger 12-volt or corded compressor.

KEEP if

You want an easy-to-store inflator for occasional tire-pressure corrections. Fanttik lists a 28.8Wh built-in lithium-ion battery, 150 PSI maximum pressure, four preset modes and USB-C charging. Follow your vehicle’s door-jamb tire-pressure label, not the tire sidewall maximum.

Know before buying

Tom’s Guide’s tire-inflator comparison found the X8 Apex easy to store but recorded a slower fill in its test and noted the short hose reach. Fanttik’s current product page advertises a 56-second increase from 28 to 33 PSI on a 215/55 R17 tire; that is a manufacturer claim under a specific test condition, not a promise for every tire. The battery is built in rather than a field-swappable pack, so keep it charged and consider a larger corded compressor for repeated or heavy-duty inflation.

Why it earns a KEEP

It combines a small footprint with preset controls, automatic shutoff and a built-in light. That is useful for occasional top-ups when storage space matters. It earns a KEEP as a portable convenience tool, not as the fastest choice for repeated inflation or larger tires.
