Title: Say Goodbye To The Trouble Of Manual Inflation! The Correct Way To Open The Rechargeable Automatic Bicycle Tire Air Pump, 90% Of People Ignore These Details

Title: Say goodbye to the trouble of manual inflation! The correct way to open the rechargeable automatic bicycle tire air pump, 90% of people ignore these details 1. Why choose a rechargeable automatic bicycle tire air pump? When you are riding in the suburbs and suddenly encounter insufficient tire pressure, the traditional manual air pump may make you tired and your arms sore, while the rechargeable automatic bicycle tire air pump only needs "one-click operation" to complete the inflation of road tires in 30 seconds. I once spent 5 minutes inflating a 28C road tire with a manual air pump during a ride around Erhai Lake, while the rechargeable pump of a friend in the same group only took 45 seconds - the efficiency gap is obvious at a glance. The core advantages of this type of equipment are: Portability: Most models are only the size of a palm, weighing about 300g, and can be put into the side pocket of a cycling bag; Intelligence: Automatically shut down at the preset tire pressure to avoid overfilling and blowout; Versatility: In addition to bicycles, it can also inflate basketballs, swimming rings, etc. (with an adapter). 2. 3 key preparations before use 1. Understand the tire pressure "code" The logo on the sidewall of the tire is the first guide, for example: "700x25C MAX 110PSI": 700C wheel diameter, 25mm tire width, maximum tire pressure 110psi; "26x1.95 40-65PSI": 26-inch wheel diameter, 1.95-inch tire width, recommended tire pressure 40-65psi. Misconception reminder: A novice once inflated a mountain tire to 100psi according to the road tire standard, but the tire slipped when cornering and the car fell off - the tire pressure must strictly match the tire type. 2. Learn the "secret codes" of 3 types of air valves Schrader: a push-type valve core, commonly found in city cars and cars, the adapter can be directly clamped; Presta: a slender valve with a threaded cap, you need to loosen the cap and pull out the valve core before use (as shown in the picture); Dunlop: rarely seen in old bicycles, a special adapter is required (some high-end pumps come with it). The first time I used a Presta valve, I didn't pull out the valve core, and the air pump kept leaking. It took me 10 minutes of embarrassing research to find the problem... 3. Equipment "health check" Battery: The indicator light is always green when fully charged, and flashes red when low on battery; Accessories: Confirm that the Schrader/Presta adapter and charging cable are complete, and the adapter thread is not stripped; Tire pressure gauge: After turning on the machine, the empty test shows 0psi. If there is a value, it needs to be calibrated (press and hold the "+" or "-" key to reset).
