Four Mini Air Compressors From CYCPLUS: But Which One To Buy?

CYCPLUS Mini-Compressor Review

The reviewer tested four CYCPLUS models by repeatedly inflating a deflated 700×32/33 road tire to 60 PSI. This was a practical comparison, not a long-term or teardown review. CYCPLUS supplied the units, but the reviewer said he was under no obligation to praise them. No formal ratings or scores were given.

Models and Test Results

• AS2: The smallest, lightest, and cheapest model. It has no pressure gauge. The first inflation took about 3 minutes to reach 60 PSI; the second reached only 39 PSI before the battery shut down. The reviewer found it difficult to use accurately without a gauge and does not recommend it for most riders.
• AS2 Ultra: A compact, lightweight model with a digital gauge and automatic pressure stop. It inflated the tire to 60 PSI twice, taking about 1:15 and 1:16. On the third attempt, it reached 40 PSI before stopping with a low-voltage warning. It is the best choice for riders prioritizing low weight and small size while still wanting a gauge.
• AS2 Pro: Similar in general function to the Ultra, but slightly larger and heavier, with a somewhat larger battery. It completed three full inflations and reached 56 PSI on a fourth. The reviewer considered it the best all-around option and sweet spot for most cyclists.
• AS2 Pro Max: The largest, heaviest, and most expensive model, with the biggest battery. It reached 60 PSI in about 29–30 seconds and did so six times, with enough charge possibly remaining for another partial inflation. It was getting hot and noisy by then. The reviewer called it a workhorse, but too bulky for a typical ride.

Other Observations

• Models with gauges show battery-level indicators. Battery capacity varies: 300 mAh for the AS2, 400 mAh for the Ultra, 420 mAh for the Pro, and 600 mAh for the Pro Max. The reviewer noted that larger batteries generally allow more inflations but also increase size and weight.
• All models that completed an inflation reached approximately the target pressure, as checked with a separate digital pressure gauge.
• The units themselves stayed manageable to hold during testing, but the valve chuck gets hot. The reviewer recommends carrying and using the included hose, especially with plastic Presta valves or TPU tubes, to reduce direct heat transfer.
• The motors sounded somewhat rattly and less refined than the VIAIR Recon Mini, though the reviewer did not observe this affecting performance.
• In the same test, the VIAIR Recon Mini took about one minute per inflation and completed four 60-PSI inflations. It was warm but not excessively hot.
• The reviewer prefers a compressor with a gauge for both puncture repairs and routine pressure top-ups. Without one, it is harder to know the tire pressure precisely.

Verdict and Recommendations

• Best for most riders: AS2 Pro — A useful balance of size, weight, and inflation capacity.
• Best for minimal weight: AS2 Ultra — Smaller and lighter, but with less battery capacity than the Pro.
• Best for home use, touring, or bikepacking: AS2 Pro Max — Fast and capable, but too large for the reviewer’s usual ride kit.
• Not recommended for most riders: AS2 — Its lack of a gauge and limited battery performance make it less practical.

The reviewer planned to use the Pro Max as a convenient home tire-top-up compressor and expected to find uses for the Pro and Ultra as well.

Other Product Comparison

The reviewer briefly mentioned Fumpa mini compressors, which he had not tested. He liked that the Fumpa model he looked up reportedly has a user-replaceable battery, since battery failure may eventually make a sealed compressor unusable.

Reviewer’s Perspective

All product assessments and recommendations came from the reviewer. He emphasized that the test was a repeated-inflation comparison rather than a long-term reliability assessment.
