Maximum pressure	120 PSI	not published
Not for	Truck or large SUV tyres from flat -- the 400P is the model for that	not published
Power	Direct to the battery with alligator clips, not a cigarette lighter socket -- a socket cannot supply the current	not published
Runtime	not published	About 18 minutes on a 5.0 Ah battery
Suction	not published	Strong for a handheld, but a 0.5 litre tank empties fast
Voltage	not published	Battery tool, so mains voltage is only a question for the charger, which is dual voltage
Wet and dry	not published	Yes, up to about 0.5 litres of liquid
Why it matters	Inflating four tyres from flat can exceed the duty cycle in one session. Let it cool between tyres	not published
Why sold this way	not published	It assumes you already own DeWalt 20V MAX batteries from other tools. If you do not, budget accordingly
