WP iGen4750PRO
The Westinghouse iGen4750PRO is the entry point into the PRO range and the one most mobile detailers start with. It gives you 3,800 running watts through a single 15 amp weatherproof outlet, with an RCD safety switch built into the control panel. That is enough to run one machine properly: a Kranzle pressure washer, a BigBoi blower, or a small air compressor. At 36 kg dry it is the only unit in the range one person can realistically load into a van on their own.
Australian machines are either 10 amp or 15 amp. Power quality is not the limiting factor here, since all three PRO generators give pure sine wave output with less than 2.5% total harmonic distortion. What limits you is the single 15 amp socket, and the 4,750 starting watts available to get a motor turning. Allow two and a half times a motor's rating for starting, or three times for an air compressor that starts against tank pressure rather than venting its head pressure when it stops.

Before you order: Petrol generators must be run outdoors in open air. Never run one inside a van, trailer, garage or any enclosed space, and keep the exhaust away from open doors and windows. Carbon monoxide is odourless.
This generator is not suitable for connection to a fixed multiple earthed neutral (MEN) electrical installation. It is designed for standalone plug and socket use. Any connection to a building's wiring must be done by a licensed electrician with the correct changeover equipment.
