LIVOWALNY WSCZ041D0A01 Cordless Tire Inflator, 160 PSI, 12V/20V

A choice of 12V DC or 20V DC power makes the LIVOWALNY WSCZ041D0A01 tire inflator useful both from a vehicle and away from a power outlet. Its LCD lets you set a target pressure, and automatic shut-off stops inflation when that setting is reached.

With airflow up to 40 L/min and maximum pressure of 160 PSI, it is designed for tire inflation as well as sports balls and other inflatables. A deflation function also helps release air from large air mattresses before storage.

If you need a compressor mainly for a fixed workshop, a plug-in unit may suit that setup. For roadside top-ups, trips and jobs around the home, this portable pump offers two power options and a built-in LED light for working in dim conditions.

The essentials

The dual-power design supports 12V DC from a vehicle’s cigarette lighter socket and cordless operation with a compatible DEWALT 20V battery. That gives you a practical choice: use the vehicle’s power for a roadside tire check, or use a battery-powered setup when you are away from the car. The product is identified as tool only, so choose the power source that fits your setup.

A digital LCD display makes the pressure setting easy to follow. Set the desired pressure and the compressor automatically shuts off at the preset level, reducing the need to watch the gauge throughout inflation. Its 40 L/min airflow and 160 PSI maximum pressure suit routine inflation tasks, including car and pickup tires, while the deflator adds another use for packing away air mattresses.

The built-in LED light can illuminate the work area when checking a tire in low light. The package details list an air hose, fuse and nozzle alongside the portable compressor, supporting use for different inflation jobs.

Best use cases

Keep the inflator in a vehicle for topping up tires, or use it at home for balls, toys and air mattresses. For example, before a trip, set the target pressure on the LCD, connect the hose and let the automatic shut-off manage the stop point. When a large mattress needs packing away, switch to deflation to release air rather than pressing it out by hand.

This is a versatile alternative to carrying separate equipment for tires and household inflatables. The dual power modes are especially useful when the job moves between a vehicle and places where cordless operation is more convenient.

Usage tips

Choose either the 12V vehicle connection or a compatible DEWALT 20V battery, then set the target pressure on the display before inflating. Match the supplied nozzle to the item being inflated and use the hose for the connection. For tire work in a dark area, the built-in LED helps light the immediate workspace. Use the deflation function when releasing air from an air mattress for storage.
