4. Q: What is the purpose of the adapters included with the Xiaomi Portable Electric Air Compressor 2 Pro? A: Without the adapter, it can be used to inflate tires with a Schrader valve. When the Presta valve adapter is attached, it can be used to inflate tires with a Presta valve. The Schrader valve is larger and shorter, allowing inflation without removing the top cap for easy operation, while the Presta valve is longer and smaller, requiring the top cap to be loosened before inflation. For your reference, here are more details about the adapters: 1. The Schrader valve adapter is used for the tires on mountain bikes, e-bikes, motorcycles, electric scooters, and cars use a Schrader valve. To inflate the tires, please connect the Schrader valve to the Schrader valve adapter on the high-pressure air hose to begin inflating. To deflate the tires, please use an appropriate tool (for example, a 4 mm hex key) to press the needle valve adapter to release the air; 2. The Fast-connecting air valve adapter can be connected to the Schrader valve for inflation. To inflate, please connect the fast-connecting air valve to the Schrader valve and press the handle down to lock it, and start inflating. To deflate, please connect the fast-connecting air valve adapter to the Schrader valve and press the fast-connecting air valve adapter down to release the air; 3. The Needle valve adapter is used to inflate balls like basketballs and footballs. To inflate balls, the included needle valve adapter is needed. To deflate, please screw the needle valve adapter onto the Schrader valve adapter, then insert the needle into the ball's valve to start deflating; 4. The Presta valve adapter is used to inflate road bikes and certain mountain bikes. To inflate, please connect the Presta valve adapter to the Schrader valve adapter on the high-pressure air hose, and unscrew the tire's Presta valve, then connect the Presta valve to the adapter to start inflating. To deflate, please unscrew the Presta valve's threaded cap and press the threaded cap down to release the air.

6. Q: Why does the power indicator not turn on when charging the Xiaomi Portable Electric Air Compressor 2 Pro? A: This can be due to issues with the adapter or charging cable. It is recommended to replace the charging cable and adapter with compliant and safe alternatives and try charging again.
7. Q: Does the Xiaomi Portable Electric Air Compressor 2 Pro need to be charged if it has been idle for a long time? A: It is recommended to charge it at least once every three months.
8. Q: Why does the sealing ring fall off when inflating a road bike tire with the Xiaomi Portable Electric Air Compressor 2 Pro? A: This happens because road bike tires have high pressure (some can reach 120 PSI). The internal sealing ring of the Presta valve experiences high pressure between the valve core and the sealing ring. When the valve is quickly unscrewed under high pressure, the sealing ring will be pushed out due to the rapid release of pressure. It is advisable to operate slowly when removing the valve after inflating to over 80 PSI, allowing the pressure reading on the air compressor to decrease before fully removing it. If the sealing ring falls off during use, it can be manually reattached and will not affect future usage.
