ST-5518 Portable Wireless Air Pump with 74V Battery and 21L/Min Airflow Rate

Features and Construction

Material and Build
ABS plastic forms the primary housing material, providing structural integrity without excessive weight that would compromise portability. This material selection supports the pump's compact dimensions while housing the 17-cylinder mechanism that generates consistent air pressure. The construction balances durability requirements for occasional automotive use with the need for transportable design elements.Size and Practical Fit
Measuring 9.4 cm in length, 5 cm in width, and 18 cm in height, the pump maintains dimensions suitable for vehicle storage compartments. These measurements allow placement in typical car boot spaces or garage shelves without occupying excessive room. The compact form factor supports the product's positioning as a portable solution rather than a permanent workshop installation.Uses and Placement

Event or Professional Use
While not designed as industrial equipment, the pump's 21L/min airflow rate provides sufficient capacity for maintaining multiple vehicle tires during events where portable inflation is required. The 74V battery capacity supports extended use between charges, making it suitable for roadside assistance scenarios or motorsport events where quick tire pressure adjustments are needed. The included nozzle set accommodates standard valve types found on most passenger vehicles.Everyday Home Use
For regular vehicle maintenance, the pump offers convenient inflation without moving cars near power outlets. Home users benefit from the integrated lighting when checking tire pressure in dimly lit garages or during evening hours. The complete kit design means all necessary components are included for immediate use without additional purchases.Benefits and Buying Value

Reuse and Low Maintenance
ABS construction requires minimal maintenance beyond occasional cleaning, while the rechargeable battery system supports repeated use without consumable replacements. The included charging cable enables standard power source connection, and the nozzle set's compatibility with common valve types ensures ongoing usability as vehicle needs change. These elements contribute to the product's potential for extended service life.Why Choose This Product
Selecting this inflation pump provides wireless convenience combined with measured performance specifications. The 21L/min airflow rate delivers efficient inflation times, while the 17-cylinder design ensures consistent pressure delivery. Compared to basic manual pumps, it reduces physical effort, and versus corded electric models, it eliminates power source limitations. The complete accessory package means immediate usability without additional component purchases.
