Features: Inflatable battery life increased by about 45.4%, Can replace about 8 tires. Gas flow rate increased by about 114%. High-precision cylinder can be charged up to 150psi. The air pressure sensor upgraded to a digital chip, the tire pressure detection accuracy is increased to ??1psi*, the error is smaller, there is no need to rely on the foot to repeatedly check whether it is full. The preset pressure is fully charged and stops immediately, saving effort and worry. 5 modes are free to switch elders use no barriers. Built-in lithium battery to get rid of wires. Lightweight, portable and easy to store.
