The CarRundown verdict.
The Fanttik B11 Pro Max is a useful fit for drivers who want adjustable airflow to loosen dry dust from cabin gaps and already have a vacuum or cloth to collect it. Its wheel covers 0–100 speed levels, while Boost and five nozzles add flexibility for different small cleanup jobs. Fanttik also lists two brushes, a keycap puller and 18W device backup. Start with low airflow around screens and trim; this blower moves debris but does not capture it. B11PROM took $30 off the checked Black variant in our US cart.
Fanttik positions the B11 Pro Max for cleaning PCs, cameras, car interiors and other small spaces. Its listed 150,000 RPM motor delivers up to 80 m/s and 160 g of blowing force, with wheel adjustment from 0 to 100 and a Boost mode. Those are manufacturer specifications, not CarRundown measurements. Fanttik lists a 28.08Wh battery, up to 245 minutes in first gear or 13 minutes in Boost, and 18W USB-C input/output. On October 23, 2026, the Black variant 50900355186931 (SKU USAFTKN1089621GW) was listed at $99.99. The B11PROM code reduced that exact item to $69.99 before tax and shipping in a fresh anonymous US cart.

What stands out
- The 0–100 speed range gives more room to adjust airflow than a small fixed set of modes, with a separate Boost option.
- Five nozzles and two brushes let owners choose a directed stream or a brush for small cleaning tasks, subject to the surface and tool instructions.
- Fanttik lists both 18W input and output, so the device can also provide backup power to compatible electronics.
- The exact Black variant accepted the model-specific B11PROM code for $30 off.
Before you buy
- Airflow shifts dirt instead of collecting it. Keep a vacuum or cloth nearby, especially when clearing debris from a car cabin.
- The maximum airflow can push dust onto adjacent surfaces. Start low around screens, controls, vents and loose trim, then raise the speed only when needed.
- The 245-minute first-gear and 13-minute Boost runtimes are manufacturer estimates for different settings, not a real-world cleaning duration.
- Fanttik says discount codes cannot be combined.
- The official product photo shows the blower and selected attachments, not a full package inventory; confirm the included items if a particular tip matters.
A small blower for the places a vacuum nozzle misses
Fanttik lists car interiors among the B11 Pro Max use cases, alongside PCs and cameras. For a car, that makes it a companion for dry dust in narrow gaps: direct airflow to move particles out, then vacuum or wipe them up. It does not pull dirt into a bin, so it is not a standalone substitute for a car vacuum. Keep debris away from people and screens while blowing it loose.
A wide control range and a short burst mode
Fanttik lists a 150,000 RPM motor, up to 80 m/s and 160 g blowing force. These are manufacturer figures rather than pickup results. The horizontal wheel adjusts from 0 to 100, and a separate Boost action provides a brief higher-output option. Use the lowest level that clears the dust near screens, buttons and vents; stronger airflow can simply send particles deeper into the cabin or across another surface.
Battery figures depend on the speed setting
The 28.08Wh battery is rated by Fanttik for up to 245 minutes in first gear or 13 minutes in Boost. That difference shows why a maximum runtime is a poor guide to repeated high-speed use. The product page lists 18W USB-C input and output and an approximately 2.5-hour charge. Power backup can be handy for a compatible device, but it does not turn this blower into a jump starter or a tire inflator.
The accessory set suits small, directed tasks
Fanttik lists five nozzles, soft and hard brushes, a keycap puller and a Type-C cable. That is a broader small-tool kit than the duster alone, but it also means more pieces to keep organized. The official hero shows the blower and several attachments, not every item in the package. Check the current box list if the cable or a particular nozzle is important to you.

Fanttik listed Black variant 50900355186931 (SKU USAFTKN1089621GW) at $99.99 on October 23, 2026 and displayed B11PROM for $30 off. A fresh anonymous US cart with that item alone showed $69.99 before tax and shipping. Fanttik says its codes cannot be combined. Confirm the current cart amount before paying.

Consider another option if
