Burst tires are the number one cause of car accidents. This smart portable pump can measure the pressure with one key, identify the current and optimal tire pressure, and select pressure compensation or relief for different tire pressures. Users can fine-tune the tire pressure to match different terrains. The inflator pump automatically stops when the optimal pressure is reached. The front lighting makes it convenient to charge at night. Moreover, it does not need a separate power supply and is compact for easy carriage.
