A smaller cordless inflator for compatible tyres and routine top-ups.
The catch: Check tyre size and duty cycle; it is not a workshop compressor.
Choose it when: Compact size matters more than the X9 Ultra’s larger battery.
US source
A portable inflator between the smaller Pro and the much larger Ultra.
The catch: Manufacturer speed figures depend on the stated tyre and pressure test; check cooling instructions.
Choose it when: You want a portable car-tyre top-up tool rather than the Ultra’s bulk.
US source
A portable alternative with a manufacturer-listed 43.2Wh battery.
The catch: Still below the Ultra’s 92.5Wh label; this is a feature-led portable option, not an across-the-board upgrade.
Choose it when: More battery capacity than the smaller APEX models is useful on trips.

Scope: X9 Ultra tire inflator. This is a research-based buying assessment using manufacturer information and the outside source identified below. Buy If Works has not carried out a hands-on test of this product.
Fanttik positions the X9 Ultra as a cordless inflator for pickup trucks and larger tyres, with a digital pressure setting, an extended hose, lighting and power-output functions. The manufacturer lists a 92.5Wh battery and accuracy claims. We have not reproduced its inflation-speed or gauge-accuracy tests.
CleanTechnica’s Danielle Garland used the X9 Ultra on Toyota Tacoma tyres and found its controls, hose storage and lighting convenient. The reviewed kit lacked a wall charging adapter, and charging a laptop consumed more battery than the reviewer expected. The article does not provide a controlled inflation-time or gauge-accuracy dataset; we therefore do not repeat the manufacturer’s speed multiplier as a measured result.

Think about when you will use the inflator: regular driveway top-ups, travel or an occasional low tyre. A cordless tool trades cable access for battery readiness. If it spends long periods in storage, checking its charge becomes part of the ownership routine. A light and easy-to-read controls are useful, but they do not answer whether the pump suits the volume of your tyres.
Keep a charging routine and check adapter contents. Controlled speed, accuracy and extended duty-cycle results have not been established here.
First-year planning: delivered product price + required extras + the consumables, optional plans and energy you expect to use.
A cost checklist, not a live price quote or a measured annual total. Check local prices and your selected bundle. Manufacturer product / support details ↗ · Checked 11 October 2026.
Price the charging equipment you need and compare the inflator with an option that suits the same tyre task. Spending more for power-bank functions makes little sense if those functions reduce the reserve you want for inflation. Check local warranty arrangements, because a portable tool is less convenient if obtaining support requires shipping it abroad.
No. USB power output does not make an inflator a jump starter.
No. Tyre volume, starting pressure, charge state and operating limits also matter.
Verify your kit. CleanTechnica’s review unit included a charging cord but no wall adapter; bundles can change.
