CYCPLUS Tiny Tire Inflator AS2 Pro Max Portable E-Pump 205g Aluminum, 120 PSI & Auto Shut-Off

The CYCPLUS Tiny Tire Inflator E-Pump AS2 Pro Max is a pocket-sized, fast-charging electric bike pump that reaches up to 120 PSI and auto-shuts off at your preset pressure.

This ultra-compact inflator combines aircraft-grade aluminum construction with a high-performance motor to deliver quick, accurate tire inflation for road, mountain, city and e-bikes. Weighing just 205 g (7.23 oz) and measuring 3.18 × 1.25 × 2.36 inches, it’s built to go everywhere you ride — clipped to a backpack or slipped into a pocket. The large LED screen and auto shut-off make inflation hands-free and precise, while fast charging and multi-valve compatibility keep it practical for everyday use and emergencies.

How fast and powerful is this mini electric pump?

The AS2 Pro Max packs surprising speed for its size. It delivers up to 120 PSI and can refill a 700×25C tyre very quickly, making it suitable for high-pressure road tires as well as lower-pressure mountain and e-bike tires.

• Maximum pressure: 120 PSI.
• Refills a 700×25C tyre in about 25 seconds (within typical road tire range).
• Inflates a road bike tire from 0–120 PSI in roughly 75 seconds.
• Designed primarily for bicycle use: e-bikes, mountain, city and road bikes.

What safety and accuracy features does it include?

The pump’s LED screen shows real-time pressure and allows you to preset a target. When the target is reached, the unit automatically stops to prevent overinflation, and the pressure accuracy is within ±1 PSI for reliable readings.

• Large LED display for clear readings in daylight or low light.
• Auto shut-off when preset pressure is achieved.
• Measurement accuracy: ±1 PSI for consistent inflation.
• Preset function for hands-free inflation to your preferred pressure.

How long does the battery last and how quickly does it recharge?

Fast charging keeps downtime minimal: a full charge takes about one hour. On a single full charge the AS2 Pro Max can inflate at least three 700×25C tyres from 0 to 120 PSI, making it convenient for multi-ride days or group outings.

• Full recharge time: ~1 hour.
• Battery endurance: at least three full 700×25C tyre inflations (0–120 PSI) per charge.
• Compact battery weighs minimally to preserve pocketability.
• LED indicators show charging and ready status.

Which valves and accessories are supported?

The AS2 Pro Max works with both Schrader and Presta valves, using a 2-in-1 nozzle for easy switching. An extra flexible air hose is included to avoid awkward angles and simplify attachment in tight spaces.

• Includes integrated 2-in-1 Schrader and Presta compatibility.
• Additional flexible hose for hard-to-reach valves and angled stems.
• Compact nozzle stores or clips neatly for transport.
• Suitable for a wide range of bicycle valve types without adapters.

Who is this for? Cyclists who value portability, speed and precision will benefit most from the CYCPLUS AS2 Pro Max. It’s ideal for road racers who need rapid high-pressure fills, e-bike riders wanting a compact emergency pump, commuters who prefer minimal weight, and weekend mountain bikers seeking a reliable pocket-sized backup. If you often ride away from convenient pumps or need a fast, accurate inflator you can carry everywhere, this tiny electric pump is built for you.
