The CYCPLUS AS2 Pro Max Tiny E-Pump is a compact, portable electric pump praised for its fast inflation, precise pressure control, and convenience compared to manual pumps or CO2. However, it is heavier and pricier than smaller models, can get hot during extended use, and its pressure gauge may be slightly inaccurate. Overall, it is recommended for cyclists seeking a reliable on-the-go inflation solution.

Reviews & Ratings
05:31The reviewer tests the CYCPLUS AS2 Pro Max Tiny E-Pump, focusing on its performance, features, and usability. They highlight its compact size, pressure display, and fast inflation, but note that it can get hot during use.
12:42The reviewer tested the CYCPLUS AS2 Pro and Pro Max electric mini pumps, noting the Pro's improved battery and display over the original, and found they performed close to claims, with the Pro inflating a 28mm tire to 80 psi in 70 seconds instead of the claimed 60 seconds. The Pro successfully completed three full inflations with cool-downs, but a torture test without cool-down caused overheating and failure. The reviewer praised the user experience, digital pressure gauge accuracy, and the Pro's compact size, but noted the premium price. They concluded that the Pro is a compelling option for long-distance cyclists who carry charging systems, and the Pro Max is nice for casual use.

He finds both high-quality and convenient, with the AS2 Pro Max being larger and heavier but with double the battery life, while the AS2 Pro is lighter and suitable for carrying on rides. Both inflate a mountain bike tire in about 70 seconds.

21:11The reviewer tested the CYCPLUS AS2 Pro Max Tiny E-Pump and found it to be a versatile performer. It was the fastest at filling a large 29er MTB tire, took 56 seconds to fill a road bike tire to 100 PSI, and achieved the highest real pressure among pumps claiming 120 PSI, reaching 7.9 bar. It remained cool during use, but it is the heaviest mini pump at 228g and its default pressure setting is always 100 PSI, which can be annoying for MTB use.
