CYCPLUS Tiny Tyre Inflator E-Pump AS2 Pro Max — 205g Aluminium, 120 PSI, LED Display

The CYCPLUS Tiny Tire Inflator E-Pump AS2 Pro Max is a pocket-sized electric pump that quickly inflates bike tires up to 120 PSI while automatically stopping at your preset pressure.

Built from lightweight aluminum and weighing just 205 g, this compact e-pump is engineered for cyclists who want fast, accurate inflation without carrying bulky tools. It combines a clear LED pressure display, two-valve compatibility, and rapid charging so you can top up road, mountain, city, and e-bike tires on the go. The design balances portability and power, making it suitable as a daily carry item for commuters and a backup for long rides.

How fast and powerful is this tiny inflator?

The AS2 Pro Max delivers surprisingly quick fill times thanks to a high-pressure motor capable of 120 PSI. For common wheel sizes, it can refill a 700x25C tire in about 25 seconds and take a road bike tire from 0 to 120 PSI in roughly 75 seconds. Performance is tuned primarily for bicycles rather than large automotive tires.

• Maximum pressure: 120 PSI
• 700x25C tire: ~25 seconds to refill
• Road tire 0→120 PSI: ~75 seconds
• Optimized for e-bikes, mountain, city, and road bikes

What safety and accuracy features does it offer?

Safety and precision are handled by an LED screen that shows real-time pressure and lets you preset the target PSI. The unit measures pressure to within ±1 PSI and will automatically stop when the chosen pressure is reached, so you avoid overinflation and can set it and forget it. The clear readout is useful in low light and roadside conditions.

• LED screen with live pressure readout
• Preset pressure function with auto shut-off
• Measurement accuracy: ±1 PSI
• Large display for easy roadside viewing

How convenient is it to carry and recharge?

Weighing only 205 g and sized to fit in a pocket or small pack, the AS2 Pro Max is truly portable and can be clipped to gear or slipped into a jersey pocket. Its aluminum alloy shell provides durability without adding bulk. The battery charges quickly — a full charge is reached in about one hour — and is rated to inflate at least three 700x25C tires from 0 to 120 PSI per charge.

• Weight: 205 g (7.23 oz)
• Dimensions: 3.18 × 1.25 × 2.36 inches
• Fast charge: ~1 hour to full
• Per-charge capacity: at least three 700×25C tire inflations

Which valves and extras are included?

The pump ships with a 2-in-1 nozzle head that fits both Schrader and Presta valves, plus an extra air hose for awkward angles or tight valve wells. Those accessories make it easy to use across multiple bike types and wheel configurations without additional adapters. The added hose simplifies inflation on frames or deep-section rims where direct access is limited.

• Compatible with Schrader and Presta valves
• Included extra air hose for difficult angles
• Compact head for tight valve spaces
• Designed for quick switch between valve types

Who is this for? The CYCPLUS AS2 Pro Max is aimed at cyclists who want a reliable, compact electric pump for daily commuting, training rides, or as a lightweight emergency backup. It suits riders of road bikes, gravel bikes, mountain bikes, city bikes, and many e-bikes who prioritize speed, accuracy, and portability. If you need a small, fast, and accurate inflator that fits in a jersey pocket or saddlebag, this model delivers the balance of convenience and performance most cyclists expect.
