CYCPLUS AS2 Pro Max Mini E‑Pump — Portable Bike Tire Inflator
Product description
Pocketable construction and materials: The unit uses a machined aluminum‑alloy shell and comes in at about 205 g (7.23 oz). Its compact footprint measures roughly 3.18 × 1.25 × 2.36 inches, so it slips into a pocket, saddle bag, or clips to a pack for quick access.
What you get and accessories: The package includes the AS2 Pro Max main pump, a short flexible air hose for awkward valve angles, a silicone protective sleeve, and a small storage pouch to keep bits together. The pump supports both Presta and Schrader fittings without extra adapters — the hose screws on for Schrader use.
Inflation performance and accuracy: This tiny inflator reaches up to 120 PSI and is tuned for bicycle tires — e‑bikes, mountain, city and road bikes all fall within its intended use. It can top up a 700×25c tire from roughly 80–100 PSI in about 25 seconds, and can inflate a road tire from 0 to 120 PSI in about 75 seconds. The LED screen displays real‑time pressure and allows you to set a target; the gauge is accurate to about ±1 PSI and the pump will stop automatically once the preset pressure is reached.
Power and runtime: A fast one‑hour recharge gives you multiple fills — the manufacturer rates at least three full 700×25c inflations per full battery, and tests commonly show several more partial or full cycles depending on starting pressure. Controls are simple for single‑handed use and the unit is designed to avoid overheating during repeated use.
How it’s used: Attach the appropriate valve connection or screw on the included hose for Schrader valves, set your desired pressure on the LED display, and press start. The pump runs automatically and shuts off when the target is hit. The compact size, light weight, and included pouch make it convenient for day rides, travel, or keeping in a car or wheelchair bag for emergencies.

VerdictA very small, well‑built electric inflator that makes roadside and travel inflation simple.

Mini pump — impressive performance
Bought this for a Cinelli bike and it inflates wheels very quickly. The silicone sleeve protects against drops and it doesn’t get uncomfortably hot during use. Compact, practical and top quality for the category.

Battery quality could be better
Disappointed — battery died after a few weeks sitting unused. Pricing shifted recently and I expected a higher‑quality cell. If longevity matters, consider alternatives or check battery health closely.

Great value and solid construction
Used it several times and it performs very well. Small enough for a fanny pack or pocket. A bit loud but not unbearable. Came with a rain‑resistant pouch I use often. Overall excellent build and value.

Handy little e‑pump to carry on rides
Works reliably and the battery lasts long enough to help me and friends mid‑ride. Lighter and smaller than most manual pumps — fits in a pocket. I prefer my floor pump for home settings, but this saves space and hassle while traveling.

Compact, effective and relatively quiet
Performs better than other options I’ve tried. Fast, powerful battery and a noticeable but lower noise level than competitors. Clean design and feels durable with useful accessories.

Tiny and potentially a lifesaver
A must for serious riders — fast and effective. Highly recommend for anyone heading out on remote routes.

Small, effective and easy to use
Read reviews and chose this model. My first unit had a charging fault and was replaced quickly. The replacement charged normally and performed as advertised — I used the short hose, set the pressure, and it shut off when done. Very straightforward.

A convert who waited and was rewarded
I rarely review, but this made roadside fixes painless. After decades in tech I was wary of e‑pumps, but at 68 I appreciated the relief from hand pumping. It’s easy to use and does exactly what it promises.

Essential for serious cyclists
Arrived early and worked great after charging. Inflated 26×2.35 Presta tires from ~40 to 60 PSI in about 20 seconds each and still showed a full charge. Shuts off at the preset pressure and is idiot‑proof — great for trail flats.

Compact with accurate readout and strong output
Very portable for rides or a car kit. Despite the size it builds pressure quickly and the gauge matched my tests. Simple controls, no overheating, fast recharge and good build quality. A dependable option for a compact pump.

A. Oulton 5/5
Very useful for wheelchair users
Inflated my wheelchair tires to 100 PSI quickly with no trouble. Compact and light so it stores easily under the chair. Charges fast and didn’t noticeably drain after two wheels. Includes a silicone cover and pouch for protection. A bit pricey but very handy.

Top performer across many tests
Best battery pump I tried. Ready for Presta straight from the box; screw on the hose for Schrader. On a full charge I inflated several road tires back‑to‑back to 100 PSI and the unit only paused when auto shutoff engaged. I got three full inflations in my test.
