The Fanttik X9 Pro is a cordless tire inflator small enough to live in a glove box. It charges over USB-C and reaches 150 PSI. You can browse Fanttik’s range on its official store.
This is a research-based look. It draws on Fanttik’s spec sheet, its published return and warranty terms and independent testing of the brand’s inflators, so you can weigh the facts before you click anything.
The short version: a light, quick inflator that suits the occasional top-up. If you often bring big tires up from empty, the brand’s larger X8 Apex is the better fit.
What the X9 Pro Is Built For
The X9 Pro is made for the small job. A low-pressure warning light comes on, you reach into the glove box and the top-up is over quickly. At 0.96 lbs, it is light enough to stay in there for good.
On paper it is quick: the brand lists about 35 seconds to take a 25-inch tire from 0 to 35 PSI. Power comes from two 2,500mAh lithium cells (18.5Wh in total) that charge over USB-C and are not meant to be swapped out, and a full charge is good for roughly 23 minutes of running.
Its 4+N intelligent presets span cars, bikes, motorcycles and balls, which stretches its use beyond a car-only tool.
Specs and What Comes in the Box
- Maximum pressure: 150 PSI
- Battery: two 2,500mAh lithium cells, 18.5Wh in total
- Charging: USB-C
- Weight: 0.96 lbs
- Fill time: about 35 seconds for a 25-inch tire from 0 to 35 PSI, as listed by the brand
- Runtime: about 23 minutes of continuous use
- Units: PSI, kPa or bar
- Shut-off: automatic after 3 minutes idle
Units are changed by holding the mode button briefly. If you forget to switch the inflator off, it stops by itself after 3 idle minutes, which spares the battery.
In the box you will find the inflator itself, a USB-C charging cable, a manual, Presta and needle valve adaptors, and an air tube that tucks away inside the body.
Looking after the battery
The batteries are built in, so upkeep comes down to how you charge and store the tool. Give it a full charge before the first use, and let the 3-minute idle shut-off end a session instead of pushing past the rated 23 minutes.
Do not leave it empty in a drawer for months. The usual advice for lithium cells is to top them up from time to time.
Who It Suits and Who Should Skip It
The X9 Pro fits drivers of sedans and crossovers who want something for the occasional low-pressure light. The presets also make it handy for a bike tire or a ball.
It is a top-up tool, not a refill machine. If you regularly bring a large truck or SUV tire up from flat, the X8 Apex carries a bigger battery and a longer rated runtime, at a higher price.
Storage deserves a thought. The listed operating range runs from 14 to 113 degrees Fahrenheit (minus 10 to 45 degrees Celsius). A trunk in midsummer or an unheated garage in a hard freeze can fall outside it, so a spot closer to room temperature suits the tool better.
How It Compares
The natural comparison is Fanttik’s own X8 Apex. Both reach 150 PSI, but the battery, weight and runtime differ.
| Spec | X9 Pro | X8 Apex |
| Battery | Two 2,500mAh cells (18.5Wh) | One 7,800mAh cell (28.8Wh) |
| Weight | 0.96 lbs | 1.74 lbs |
| Runtime | About 23 minutes | Up to 40 minutes |
| Listed fill time | About 35 seconds, 25-inch tire, 0 to 35 PSI | About 52 seconds, 25-inch tire, 30 to 35 PSI |
The two fill times start from different pressures, so read them as each model’s own spec, not a head-to-head race.
In plain terms, the X9 Pro is the lighter, glove-box-sized choice, and the X8 Apex trades some of that portability for more battery and a longer run. Neither is the wrong answer. They are aimed at different drivers.
In outside testing against rival inflators, the X8 Apex needed under a minute to bring a 215/55 R17 tire from 28 up to 33 PSI. Some industry reviewers place it among the faster models that include a gauge.
AstroAI is a budget rival. One independent multi-model test averaged about 4 minutes 31 seconds per tire for an AstroAI inflator, used to top off a mid-size sedan on one charge. In an independent ranking of inflator makers, Fanttik placed second, behind VIAIR, and AstroAI eighth.
AstroAI generally costs less. Fanttik asks for a little more, and the ranking above credits it for a compact, lightweight body and USB-C charging.
Support, Returns and Warranty
These terms come from Fanttik’s published policy pages. Read them before you order, because most of the fine print is about the official store.
- Return window: 30 days from delivery, for items that are unused, unopened and in the original packaging
- Return process: contact the brand’s support team for authorization before you ship anything back
- Return shipping: you pay, unless the item arrived damaged or wrong
- Refund: sent to the original payment method within 1 to 8 business days of processing
- Warranty: 1 year from receipt on most tools bought through official channels, and it cannot be transferred
- Shipping: free when you order direct from Fanttik, with 1 to 2 business days of processing and 3 to 9 business days of delivery
Custom or personalized items are not returnable. The brand does not ship to Alaska, Hawaii, Puerto Rico, other U.S. territories, PO boxes or military addresses.
Buy through an unauthorized seller and the warranty drops to a single replacement of the same model. Discontinued items are excluded. An optional accident damage plan through AIG is offered on higher-priced items.
Before You Buy
The brand advertises a 24-hour response time and lifetime technical support. Third-party review sites suggest real replies can take longer.
Fanttik has also said publicly that scammers pose as its support team and ask for card or bank details by phone. The company says it never asks for that, and its where-to-buy page lists its own store next to several big-box retailers.
If a quick return process matters to you, an authorized retailer with its own return rules is worth a look. Otherwise, the simplest route to the full warranty and the 30-day window is Fanttik’s own store.
Fanttik makes more than inflators. The range includes the Slim V8 Apex car vacuum with 19,000Pa of maximum suction, and DIY tools such as the F2 Master rotary tool and the T1 Max soldering iron. Each one is built for a different job, so a good inflator tells you little about the rest.
On the plus side, Fanttik products have collected nine iF Design Award wins, judged by an independent design organization. The company is also young. It spun out of Aukey as its own brand in 2022 under CEO Bo Du, so its record as a standalone company is short.
FAQ
How fast does the X9 Pro inflate a tire?
The spec sheet lists about 35 seconds to take a 25-inch tire from 0 to 35 PSI.
Can it refill a completely flat tire?
Its design is aimed at topping off a tire that has lost some pressure. If bringing tires up from flat is a regular chore, the X8 Apex with its bigger battery suits that work better.
Does it work on bikes and balls?
Yes. It has presets for bikes, motorcycles and balls, and the box includes a Presta valve adaptor and a needle valve adaptor.
How do I charge it?
Through the USB-C cable in the box. The two lithium batteries are built in rather than swappable.
Does Fanttik still belong to Aukey?
No. Fanttik began in Aukey’s electric tools division and has been a separate company since 2022.
What is the return window?
Thirty days from delivery, for unused and unopened items in the original packaging. You need the support team’s authorization before shipping anything back.
The Verdict
The X9 Pro is built for quick top-ups from a tool small enough to forget about in the glove box. Its listed specs are solid for the size. Independent testing of the larger X8 Apex found it fast, but the X9 Pro’s own speed figures rest on the brand’s spec sheet.
It will not replace a bigger inflator for heavy jobs, and it is not meant to. What you get is a compact, glove-box-sized tool for everyday tire top-ups.
Skip it if you refill big tires from empty on a regular basis, and go in with realistic expectations about support. For everyone else, look up the X9 Pro’s current price on Fanttik’s site.
