The CarRundown verdict.
We recommend the Fanttik X10 Pro Max for drivers who want a cordless inflator that can also release tire pressure through a one-click side valve. Its 27.75Wh battery, SUV preset, automatic stop and large display suit off-road trips better than Fanttik’s pocket-size pumps. At 2.47 lb, it takes more room and carries more weight; its main advantage is the air-down control. The exact Default Title variant accepted X10PROM at $99.99 before tax and shipping.
The X10 Pro Max adds one-click deflation to Fanttik’s portable inflator lineup, so the same cordless unit can raise pressure for the road and release it again for a lower-pressure off-road setup. Fanttik lists four modes for SUVs, sedans, motorcycles and bikes, a 27.75Wh battery, 150 PSI maximum and automatic shutoff at the selected inflation target. Shopify’s official feed showed this exact Default Title variant published on January 8, 2026. On October 23, Fanttik listed it at $129.99 USD and advertised code X10PROM for $30 off; the code applied to variant 48339251593459 at $99.99 before tax and shipping.

What stands out
- The one-click side release makes this a rare portable pump that can also lower tire pressure for off-road setup
- The 27.75Wh battery, four vehicle presets and automatic inflation stop support cordless roadside and trail use
- A larger screen, progress display and 200-lumen light make pressure adjustments easier to follow in low light
- Fanttik’s X10PROM code applied to the exact Default Title variant for $30 off
Before you buy
- At 2.47 lb, it is noticeably heavier than Fanttik’s compact X9 Pro; carry the added size for the deflate function and larger battery
- Fanttik’s comparison table lists 30 seconds for one 25-inch, five-PSI top-up, while a separate graphic cites 36 seconds for a 245/75 R17 tire; these are manufacturer examples, not our test
- The page says one charge can refill 10 R17 tires, while its comparison table lists five 25-inch tires from 0 to 35 PSI; test conditions are not reconciled
- Fanttik says the screen does not show settled pressure during deflation; pause and wait 1–2 seconds before reading it
- The product page does not publish a numeric duty cycle or full charging time, so it is not a substitute for a shop compressor or continuous air-tool supply
The one-click deflate valve changes the use case
Most portable inflators only add air. Fanttik positions the X10 Pro Max for drivers who also want to release pressure after leaving pavement, using a side valve instead of a separate deflator. The pump can then raise pressure again before the vehicle returns to road use. That makes the model a more focused choice for off-road trips than the smaller X9 Pro, which is designed around compact routine top-ups. Air down only for the conditions and tire setup you understand, and restore the vehicle’s required road pressure before normal driving.
Treat the pressure display as a stop-and-check tool while airing down
Fanttik says the screen reading can lag while air is being released. Its FAQ advises releasing pressure, pausing for one to two seconds, then reading the settled value before continuing. That small pause matters when making a measured change near a target. For ordinary on-road driving, use the cold pressure on the vehicle placard or owner’s manual; 150 PSI is the inflator’s maximum rating, not a recommended tire pressure. The automatic cutoff applies to inflation at a selected target, while deflation is controlled with the side release.
Compare the advertised speed claims carefully
Fanttik’s comparison table states 30 seconds to raise a 25-inch tire from 30 to 35 PSI. A separate feature graphic advertises 36 seconds for a 245/75 R17 tire, and the product copy also gives a 15-second example for a smaller R15 tire from 30 to 33 PSI. Those figures use different tire descriptions and pressure changes. They are manufacturer examples, not a single apples-to-apples result or a CarRundown measurement. The 150 PSI maximum likewise says nothing about how quickly a specific tire will inflate.
Balance the larger battery against the extra carry weight
Fanttik lists a 27.75Wh battery, 15W charging input and a 2.47-pound weight. The same page describes up to 10 R17 refills, while its comparison table lists five 25-inch tires from flat to 35 PSI. Since those claims do not share stated conditions, we would not use either count as a guaranteed trip capacity. Charge the unit before travel and check the exact package graphic: it shows a storage pouch, air tube, adapters, cable and manual alongside the inflator.

A good fit for
SUV and off-road drivers who want one portable battery pump for both inflation and intentional pressure release, and who are comfortable with its 2.47-pound carry weight. Fanttik’s X10PROM code applied to this exact variant; verify the current offer and total before buying.
Consider another option if
Drivers who only need a compact emergency top-up pump, want published repeat-use duty-cycle conditions, or expect a portable inflator to run garage air tools.
