The Need for a Compact Inflation Solution
For years, I relied on a frame pump, but its bulkiness made carrying it inconvenient. Switching to CO2 cartridges offered compactness but the inability to fly with them presented challenges for international travel. The search for a better alternative led me to explore electric mini pumps.
I've been running 28mm tires for two years without a single flat, but leaks still happen. An inflation device offers peace of mind, especially during long rides or when traveling. The allure of a small, portable electric pump for quick inflations on the go was incredibly appealing.
The size and portability were paramount. I wanted something that wouldn't take up much space in my backpack or jersey pocket and could easily inflate my tires. The convenience of an electric pump outweighed the potential drawbacks for me.
Introducing the CYCPLUS AS2 Mini Pump
I discovered CYCPLUS, a Chinese brand specializing in cycling accessories, including smart trainers and electric mini pumps. They offered me the AS2 mini pump for review; a welcome opportunity since a previous request to another brand went unanswered.
The AS2 is the smallest model in their lineup, weighing approximately 119g. I tested it extensively for about a month, focusing on inflation speed and reliability. Successfully inflating my tires to 50 PSI consistently.
I was impressed by its size, ability to inflate to 50 PSI easily, and charging capabilities. The AS2 is a significant improvement over other compact inflation options I've tested.
CYCPLUS AS2 Series Comparison: AS2, AS2 Pro, and AS2 Pro Max
CYCPLUS offers three electric mini pumps: the AS2, AS2 Pro, and AS2 Pro Max. The AS2 is the most compact, while the Pro and Pro Max versions feature digital readouts and pre-set inflation capabilities. The Pro Max boasts faster inflation and a higher PSI limit.
The AS2 Pro allows setting a desired PSI before starting. Upon reaching the set point, it automatically shuts off. The Pro Max inflates even faster but is larger and heavier than the AS2 and AS2 Pro. The weight increase wasn't a dealbreaker for me.
I focused on the AS2 for its portability, but the Pro models offer additional features for those needing higher PSI or prefer digital control. The Pro’s automatic shutoff is a particularly useful safety feature.
Performance and Accuracy Testing
During testing, I discovered the AS2 Pro and AS2 Pro Max over-inflated slightly compared to the preset PSI. This wasn't a major issue, but worth noting for accuracy. The discrepancy seems minor and may be due to the nature of the pressure sensor in the device.
The AS2 consistently inflated tires to my desired 50 PSI. The faster inflation speed of the Pro and Pro Max is noticeable, but the increased size might make them less ideal for carrying on the bike.
The accuracy is slightly off, the auto-shutoff of the Pro and Pro Max is helpful. The AS2 is ideal for my needs, but the Pro series offers added convenience for riders who need more features or higher pressure inflation.
Final Verdict and Recommendations
The CYCPLUS AS2 Mini Pump is a well-designed and practical portable solution for inflating bicycle tires. Its small size and weight make it an excellent choice for carrying on rides or trips. Its ability to inflate tires consistently to around 50 PSI was more than enough for my needs.
While the AS2 Pro and Pro Max offer additional features such as digital readouts and pre-set inflation, they are slightly larger and heavier than the AS2. Therefore, the AS2 is better for compact portability, while the Pro series suits those who prioritize added features.
For cyclists seeking a reliable, compact, and convenient way to inflate their tires, especially those who are traveling, the CYCPLUS AS2 Mini Pump is highly recommended. The additional cost for the Pro models is justified if the extra features are needed, but the AS2's portability and performance alone make it a great addition to any cyclist's toolkit.
