Short answer: buy the Fanttik X9 APEX if you drive an SUV or want a faster, longer-lasting inflator that doubles as a power bank. Buy the Fanttik X9 Pro if you drive a sedan, motorcycle or bike and want the lightest, cheapest way to keep tires topped up.
Both models sit in the same X9 family and both reach the same 150 PSI ceiling, so the naming confuses people. The difference is not pressure — it is inflation speed, battery size and what each one is officially rated to inflate. Below is every published spec difference, straight from the Fanttik spec tables.

The Differences That Actually Matter
1. Inflation speed: the APEX is twice as fast on the same tire
On the identical benchmark — a 25-inch tire topped up from 30 to 35 PSI — the X9 APEX finishes in 35 seconds and the X9 Pro takes 70 seconds. That is a straight 2x gap on the same job, measured the same way.
Five PSI on one tire is not where this matters. It matters when you check all four corners on a cold morning. Across four tires the APEX saves you over two minutes of standing around holding a pump — small on paper, noticeable when it is raining.
For the X9 Pro, Fanttik publishes the underlying airflow figure: 17 L/min, which fully inflates a motorcycle tire from 0 to 35 PSI in under 2 minutes, and tops one up from 28 to 35 PSI in about 36 seconds. That is genuinely quick for two-wheeler duty — the Pro is not slow, the APEX is simply faster.
2. Vehicle rating: SUV owners should not buy the Pro
This is the single cleanest dividing line between the two. The X9 APEX is rated for SUV, sedan, motorcycle and bike. The X9 Pro is rated for sedan, motorcycle and bike — SUVs are not on its list.
Both units hit 150 PSI, so this is not a pressure limit. It is a volume question: a larger SUV tire holds more air, so each fill takes longer and asks more of the pump and battery. The APEX has the speed and battery headroom to cover that class. If your daily driver is an SUV, treat the APEX as the entry point rather than an upgrade.
3. Battery: 28.86 Wh vs 18.5 Wh, and what it buys you
The X9 APEX carries a 28.86 Wh battery against the X9 Pro's 18.5 Wh — about 56% more energy on board. The published tire counts follow: from 0 to 35 PSI on a 25-inch tire, the APEX does 4 tires on a charge and the Pro does 3.
Read those numbers as worst-case. Inflating from zero is the hardest thing either pump will ever do. In normal seasonal top-ups of a few PSI per tire, both go much further — Fanttik states the X9 Pro can refill 10 car tires on a single charge in the 28–36 PSI range, and run up to 30 minutes of continuous cordless inflation.
Recharging is where the gap widens again. The APEX accepts up to 27W input; the Pro tops out at 10W. If you are the kind of owner who remembers the inflator only the night before a road trip, faster recharge is worth more than it sounds. The X9 Pro reaches a full charge in 2.5 hours.
That bigger pack also earns the APEX a second job: it outputs up to 27W, so the same pack that inflates your tires can charge a phone. The X9 Pro's spec sheet lists no power-bank output — it is an inflator, full stop.
4. Weight and light: portability vs presence
The X9 Pro weighs 0.96 lbs; the X9 APEX weighs 1.87 lbs — near enough double. Fanttik positions the Pro as a pocket-and-backpack tool, and at 0.96 lbs on the spec sheet it genuinely is. The APEX asks for a glovebox or trunk slot.
The work light scales the same way: 80 LM on the APEX against 20 LM on the Pro, a 4x difference. Twenty lumens is enough to see a valve stem; eighty lumens lights up the wheel well and the ground you are kneeling on. Anyone who has changed pressure on an unlit shoulder at night will know which side of that they want.
5. What they share
Do not over-read the gap. Both models max out at 150 PSI and both list an adjustable preset mode on their spec sheets. On the X9 Pro that system is spelled out as 4+N modes — presets for cars, e-bikes, bikes and balls, plus a manual mode for any target pressure you set, and it auto-stops once the tire reaches the preset value, so it will not over-inflate while you look away. The Pro also uses a smart on/off hose that powers the unit up when you pull the hose from its panel and shuts it down after 3 minutes of non-use.
Which One Should You Buy?
Buy the Fanttik X9 APEX ($69.99 as of writing) if:
- You drive an SUV — the Pro is not rated for it
- You inflate four tires at a time and want to halve the time (35s vs 70s per top-up)
- You want one device that also charges a phone (27W output)
- You often work in the dark and want the 80 LM light
- You want the faster 27W recharge before a trip
Buy the Fanttik X9 Pro ($52.99 as of writing) if:
- Your vehicle is a sedan, motorcycle or bike
- Weight is the priority — 0.96 lbs versus 1.87 lbs
- You want the lower price and still need the full 150 PSI ceiling
- You mainly do seasonal top-ups, where 3 tires from flat is plenty of margin
- You want the smart on/off hose and 4+N preset modes in the smallest possible package
Put simply: the X9 Pro is the portable one, the X9 APEX is the capable one. The $17 difference between them buys speed, SUV coverage, a bigger battery, faster charging, a brighter light and power-bank output — a lot for the money if you need any two of those. If you need none of them, the Pro is the better-value buy.
FAQ
Is the Fanttik X9 APEX better than the X9 Pro?
On specs, yes — it is faster (35s vs 70s on a 25-inch tire from 30 to 35 PSI), carries a larger 28.86 Wh battery, adds SUV compatibility, charges at 27W instead of 10W and works as a power bank. "Better" only matters if you use those advantages; for a sedan owner who values a 0.96 lb tool, the Pro is the better fit.
What is the difference between Fanttik APEX and Pro naming?
Within the X9 line, Pro is the compact, lighter model and APEX is the higher-output model. They share the 150 PSI maximum pressure and adjustable preset modes, but APEX adds SUV rating, roughly 56% more battery capacity, 27W in and out, and a 4x brighter LED light.
Can the Fanttik X9 Pro inflate SUV tires?
Fanttik lists the X9 Pro as compatible with sedans, motorcycles and bikes; SUVs are not in its compatibility list. The X9 APEX is the model rated for SUV, sedan, motorcycle and bike. If you own an SUV, choose the APEX.
Do both models reach 150 PSI?
Yes. Maximum pressure is 150 PSI on both the X9 APEX and the X9 Pro. The difference is how quickly they get there and how many tires they can do per charge, not the ceiling itself.
