Fanttik B10 vs B11 Air Duster: Which to Buy

Short answer: the B11 generation wins on paper. Buy the B11 Pro ($49.99) for everyday dusting, the B11 Pro Max ($74.99) if you also want inflation, and the B11 Apex ($99.99) for the longest runtime of the five. Choose a B10 only on discount.

Quick Answer: B10 vs B11 Air Duster Specs Compared

Every figure below is taken from Fanttik's published product spec table for each model, so the five units are directly comparable. Prices are the listed US prices at the time of writing. Fanttik also sells the B11 Mix and B11 Mix Pro 2-in-1 air dusters; they are outside this comparison, so every "only", "largest" and "longest" below refers to these five models.

The Differences That Actually Matter

1. Wind speed: B11 is the faster generation

Both B10 models are rated at 65 m/s. The B11 Pro steps up to 72 m/s, and the B11 Pro Max and B11 Apex both reach 80 m/s. That is a 23% higher rated air speed at the top of this comparison versus either B10 model.

Air speed is what dislodges packed dust from keyboard gaps, PC heatsink fins, camera lens barrels and car air vents. If the job is loose surface dust, 65 m/s is plenty. If you are clearing a clogged radiator or a dusty desktop tower that has not been opened in two years, the 80 m/s models are the ones to look at.

2. Speed control: 3 steps, 6 steps, or 100

This is the clearest generational split on the spec sheet. The B10 Pro gives you 3 fixed speeds. The B10 Pro Max doubles that to 6. All three B11 models here jump to 100-speed control, and the B11 Pro and B11 Apex add dual-mode control on top of it.

Practically, fine speed control matters most on delicate work — mechanical keyboard switches, camera sensors, model kits, vinyl records — where full blast can push debris deeper or knock small parts loose. With 3 steps you are choosing between "too gentle" and "too strong" more often than you would like.

3. Runtime: the gap is enormous

Rated battery life on the first gear setting runs from 40 minutes on the B10 Pro all the way to 300 minutes on the B11 Apex. The order is: B10 Pro 40 min, B11 Pro 105 min, B10 Pro Max 210 min, B11 Pro Max 245 min, B11 Apex 300 min.

Note what happens at the $49.99 price point. The B10 Pro and B11 Pro cost the same and carry the same 17.76 Wh battery, but the B11 Pro is rated for 105 minutes against the B10 Pro's 40 minutes — more than double the runtime from an identical cell. That is the single strongest argument for skipping the older generation.

The B11 Apex's 42.12 Wh pack is the largest of the five by a wide margin, roughly 1.5× the B11 Pro Max and 2.4× the B11 Pro.

4. Charging: 18 W on the B11 Pro Max and B11 Apex

The B10 Pro, B10 Pro Max and B11 Pro all charge over 10 W Type-C. The B11 Pro Max and B11 Apex use 18 W Type-C.

The effect shows up in charge times relative to pack size. The B11 Pro Max holds a 28.08 Wh battery and refills in 2 hours; the B10 Pro Max holds a comparable 28.8 Wh battery but needs 3.5 hours on its 10 W input. The B11 Apex carries the biggest battery of these five — 42.12 Wh — and still fully charges in 2.7 hours, faster than the smaller B10 Pro Max.

5. Inflation: the B11 Pro and B11 Apex are blow-only

Do not skip this row. The B10 Pro, B10 Pro Max and B11 Pro Max are all listed as Blow Dust / Inflate. The B11 Pro and B11 Apex are listed as Blow Dust only.

So the newest generation is not a straight upgrade on every axis. If you want one device that both blasts dust and tops up an air mattress, a pool float or a sports ball, your choice narrows to the B10 Pro, the B10 Pro Max, or the B11 Pro Max. Of the three B11 models compared here, the B11 Pro Max is the only one that keeps that capability.

6. Power backup: every model here except the B10 Pro

The power backup function is listed as supported on the B10 Pro Max, B11 Pro, B11 Pro Max and B11 Apex, and not supported on the B10 Pro. All five models include an LED light.

Which One Should You Buy?

Desk, keyboard and PC cleaning, best value: the B11 Pro at $49.99. It matches the B10 Pro's price and battery size while delivering 72 m/s instead of 65 m/s, 105 minutes instead of 40, 100-speed dual-mode control instead of 3 fixed steps, and it adds the power backup function. Only give this up if you specifically need inflation.

One tool for dusting and inflating: the B11 Pro Max at $74.99. It is the only B11 here that keeps the Blow Dust / Inflate combination, and it also happens to undercut the B10 Pro Max by $5 while beating it on wind speed (80 vs 65 m/s), runtime (245 vs 210 min) and charge time (2 h vs 3.5 h).

All-day or professional use: the B11 Apex at $99.99. Its 42.12 Wh battery and 300-minute rating are the largest and longest of the five, and it charges at 18 W. Remember it is blow-only.

Tight budget, occasional light use: the B10 Pro at $49.99. It is the entry point, but at the same list price the B11 Pro matches or beats it on every row except inflation — the two share an identical 17.76 Wh battery, 10 W charging and 2.5 h charge time, and the B11 Pro wins on wind speed, speed control, runtime and power backup. Buy the B10 Pro when it is discounted, or when you specifically want the inflate function for under $50.

Long runtime plus inflation on a deal: the B10 Pro Max at $79.99. It still offers 210 minutes and inflation, but the B11 Pro Max is cheaper and better on the spec sheet, so this one makes sense mainly at a discount.

FAQ

What is the difference between the Fanttik B10 and B11?

Across the five models compared here, the B11 generation raises rated wind speed from 65 m/s to 72–80 m/s, replaces the B10's 3- or 6-step speed control with 100-speed control, and extends runtime substantially. The trade-off is that the B11 Pro and B11 Apex are blow-only, while both B10 models can also inflate.

Fanttik B10 Pro vs Pro Max — which should I get?

Both are rated at 65 m/s and both can blow and inflate. The B10 Pro Max ($79.99) has 6 speeds instead of 3, a 28.8 Wh battery instead of 17.76 Wh, 210 minutes of runtime instead of 40, and adds the power backup function that the B10 Pro ($49.99) lacks. The B10 Pro charges faster in absolute terms (2.5 h vs 3.5 h) simply because its battery is smaller.

Which of these five Fanttik air dusters lasts the longest on a charge?

The B11 Apex, rated at a maximum of 300 minutes on first gear from a 42.12 Wh battery. The B11 Pro Max follows at 245 minutes, then the B10 Pro Max at 210 minutes.

Can the Fanttik B11 Pro inflate things as well as blow dust?

No. The B11 Pro's spec sheet lists Blow Dust only. Of the three B11 models compared here, only the B11 Pro Max is listed as Blow Dust / Inflate. Both the B10 Pro and B10 Pro Max support inflation.
