ETENWOLF Car air compressor S3 Zephyr 11.03 bar 7800mAh

The Etenwolf S3 Zephyr is a cordless car air compressor designed to inflate tyres on cars, SUVs, light vans, motorcycles and bicycles. It reaches a maximum pressure of 11.03 bar (160 PSI) and an airflow of up to 22 l/min. According to the manufacturer, its metal motor and twin-cylinder design inflate up to twice as fast as typical models, and the unit is claimed to last up to three times longer than typical electric compressors. An LED light helps with use in the dark and with roadside breakdowns.

The compressor uses an efficient drive system and active cooling, so it can run continuously without pauses. Its 100% duty cycle allows all four tyres of a car to be inflated one after another. A 235/45 R18 SUV tyre rises from 30 to 35 PSI in under a minute. The 132 W output also handles larger tyres used on leisure and utility vehicles.

The built-in 7800 mAh lithium battery provides long operation on a single charge, enough to inflate around 16 tyres from 30 to 35 PSI when fully charged. It charges via USB-C with up to 15 W input, so standard USB-C chargers can be used. The unit also works as a power bank for charging mobile devices on the go. Preset modes for car, bicycle and ball, plus a manual mode with ±1 PSI accuracy and automatic shut-off, make inflation precise.
