Score is calculated from the manufacturer's published specifications. BaniCar has not handled this unit. Specs and availability change — verify on the listing.
Safety note: Never exceed the tire pressure printed on your door-jamb placard. Inflator PSI claims are the manufacturer's; verify with a separate gauge.
Verdict
The inflator you will actually keep in the door pocket. Great for top-offs on cars and bikes; fleet or truck owners who need to fill from flat should buy something with a cord.

Frequently asked questions
Can I plug the X8 APEX into my car's 12 V socket?
No. It charges only over USB-C (5 V 3 A) and runs on its internal battery. You can charge it from a USB-C car adapter between uses.
How many tires can it fill on one charge?
Fanttik claims up to 40 minutes of continuous runtime and that it can top off 17 tires without pausing. Filling from flat uses far more of the battery than a 5 PSI top-off.
Will it re-seat a tubeless bead?
Fanttik says no — it cannot re-seat a tubeless tire whose bead has popped off the rim.
