The X9 Pro reviewed previously is an excellent compact inflator for everyday car and bike use. The X9 Ultra is a different product aimed at a different user. Where the Pro is sized for a glovebox and built for compact cars, the Ultra is built for pickup trucks, RVs, and light commercial vehicles with larger tires that demand more air volume and more battery power to fill efficiently.

The step up is not just about bigger numbers on the spec sheet. The Ultra adds a 92.5Wh power station function, a 45-inch hose designed to reach all four corners of a large pickup without repositioning the unit, four user-programmable pressure memory modes, and a built-in flashlight. It is designed to be the one tool in the truck bed or camper that handles tire inflation, emergency power, and low-light situations at the same time.
For pickup truck owners, RV travelers, and outdoor enthusiasts who camp or overlander regularly, this combination of features in a single portable unit represents a meaningful convenience upgrade over carrying separate tools for each function.
The 3 in 1 Design Explained:
Tire Inflator: 38 seconds on a 33-inch truck tire from 30 to 35 PSI. Handles cars, SUVs, pickups, motorcycles, and bicycles up to 150 PSI
Power Station: 92.5Wh battery provides stable power output for drones, laptops, smartphones, and other portable devices via USB or DC output
Flashlight: Built-in flashlight for roadside use in low-light conditions or campsite illumination at night
Key Features:
38 Second Inflation on a 33 Inch Truck Tire: The X9 Ultra’s headline spec is 38 seconds to bring a 33-inch truck tire from 30 to 35 PSI. That is a significantly larger tire than the compact car tire referenced in the X9 Pro’s one-minute claim, which means the Ultra’s motor is doing considerably more work in less time. The 18.5V battery system provides the power headroom needed for this kind of output without thermal throttling on repeated fills. For a fleet operator or anyone who needs to check and top multiple large tires regularly, this speed advantage compounds quickly across a session.
Four Customizable Memory Modes (M1 to M4): Rather than preset vehicle-type modes, the Ultra offers four user-programmable slots where you save your own preferred pressure values. Set M1 to your truck’s front tire pressure, M2 to the rears, M3 to your trailer tires, and M4 to your motorcycle. The next time you use it, select the mode and walk away. This is a more practical approach than fixed presets for users with multiple vehicles at known pressures, eliminating the need to manually input the same value every session.
45-Inch Integrated Hose for Large Vehicles: A standard inflator hose forces you to reposition the unit between each tire on a large pickup or RV. The 45-inch hose on the X9 Ultra gives enough reach to move from tire to tire on a full-size truck without lifting or moving the inflator body. The hose stores integrated into the bottom of the unit, keeping it accessible without a separate bag or the risk of losing it between uses.
92.5Wh Power Station with 25-Tire Capacity: The battery is large enough to top up 25 pickup truck tires from 30 to 35 PSI on a single charge, or inflate 4.5 tires from completely flat. As a power station, 92.5Wh is a useful capacity for charging phones, running a drone, or powering a small laptop during a camping trip or at a remote worksite. The dual function means the battery is earning its weight even when the inflator is not in active use.
Auto-Stop at 1 PSI Accuracy: The X9 Ultra maintains the auto-stop feature from the Pro, stopping inflation precisely when the preset or memory mode pressure is reached. The claimed accuracy of 1 PSI is the level of precision that matters for tire maintenance, where being two or three PSI over or under the manufacturer’s specification has measurable effects on tire wear and fuel economy over time.
The Four Memory Modes :
M1, User Preset: Save your most-used pressure value, ideal for primary vehicle front tires
M2, User Preset: Second saved pressure, useful for rear tires or a secondary vehicle
M3, User Preset: Third saved pressure, works well for trailer or RV tire specifications
M4, User Preset: Fourth saved pressure, flexible slot for motorcycle, bicycle, or additional vehicle

- – Fanttik is newer in the market, long-term durability less established
Use Cases:
The 38-second claim is on a 33-inch truck tire, which is a considerably larger volume than the compact car tire used as the benchmark in the X9 Pro’s one-minute claim. That context matters. Filling a larger tire faster is a function of the 18.5V motor delivering significantly more airflow than the Pro’s 7.4V system. For a pickup truck owner checking all four tires before a highway trip or a work run, the speed advantage is meaningful across the full session.
The 25-tire top-up capacity per charge is the specification that distinguishes the Ultra from every other compact inflator in this category. No competing portable unit comes close to that figure at this size. For commercial users, farmers, contractors, or anyone managing a small vehicle fleet, the ability to work through multiple vehicles on a single charge without stopping to recharge is a genuinely practical operational advantage.
The power station function earns its design real estate. A 92.5Wh battery is a meaningful capacity for a camping trip or an off-road worksite where USB charging for phones is a daily need and occasional drone battery management is part of the routine. It does not replace a dedicated portable power station for heavy loads, but for the kind of power needs that come with truck-based outdoor work or travel, it removes the need to carry a separate device.
The 45-inch hose is the feature that truck and RV owners will appreciate most in day-to-day use. On a standard half-ton pickup, the rear passenger tire is typically the furthest point from the tailgate where you would place the inflator. A short hose means picking up and repositioning the unit between each tire. The 45-inch hose handles all four tires from a single central position on most full-size trucks.
The 80 dB Trade-Off Is Worth Acknowledging: The X9 Ultra runs at 80 dB, compared to the X9 Pro’s 60 dB. That is not a small step. In practice, 80 dB is roughly equivalent to a busy road or a noisy restaurant, while 60 dB is closer to a normal conversation. For residential early-morning use or apartment parking structures, the Ultra is noticeably louder in a way that matters to neighbors. For outdoor worksites, farms, campsites, and highway shoulders, it is not a meaningful concern. Buyers choosing between the two models should weigh noise level as a genuine factor rather than a minor footnote.
Who Is This For?
Buy it if you are … A pickup truck or SUV owner who wants a fast, capable inflator that handles the full vehicle rather than just topping up a compact car tire. RV travelers or overlanders who spend time in remote locations and need tire management, emergency power, and lighting in a single portable unit. Fleet managers or contractors checking multiple vehicles regularly where battery capacity and speed across a full session matter. Anyone upgrading from a corded inflator who wants cordless freedom without sacrificing capability on large tires.
Skip it if you are … A compact car or hatchback driver who rarely needs more than a five-PSI top-up. Buyers in residential settings where 80 dB noise in a shared car park or apartment building is a genuine concern for early morning use. Those looking for the most compact glovebox inflator with the smallest footprint. Anyone who already owns the X9 Pro and primarily drives a compact car, where the upgrade does not match the use case.
Overall:
The Fanttik X9 Ultra earns its flagship label and its score of 9.2 by delivering a genuinely superior feature set for the truck, RV, and SUV segment that the X9 Pro was never designed to serve. The 38-second inflation speed on a 33-inch tire, 25-fill battery capacity, 45-inch hose, programmable memory modes, and 92.5Wh power station function represent a coherent, well-thought-out product rather than a spec-padded upgrade over a compact inflator.
The noise level is the one area where the choice comes with a real trade-off. At 80 dB versus the Pro’s 60 dB, the Ultra is noticeably louder, and that matters in some contexts. For the outdoor, commercial, and large-vehicle use cases it is built for, it is not a dealbreaker. For urban early-morning use in shared spaces, it is worth considering seriously.
Compared to the DeWalt DCC020IB, another well-regarded cordless option for truck owners, the Ultra wins on hose length, power station functionality, and programmable modes. The DeWalt benefits from being part of an established tool battery ecosystem, which matters for buyers already invested in that platform. For everyone else, the Ultra stands on its own merits comfortably.
If you drive a truck, run an RV, or manage vehicles with larger-than-average tires, the X9 Ultra is one of the most complete portable inflators available without stepping up to a fixed workshop compressor. It does what it promises, and then some.
