Need reliable power without the noise? The iTechworld Redback RB4.5 Portable Inverter Generator 4500W 4.5KVA delivers quiet, efficient performance anywhere.
Introducing the iTechworld Redback RB4.5 Portable Inverter Generator 4500W 4.5KVA, a fuel-efficient, quiet and powerful solution built specifically for Aussie caravaners and off-grid explorers. Whether you're heading into the bush or setting up for a long stay off the beaten track, the RB4.5 makes sure you’ve got all the comforts of home without needing a powered site.
This 4.5KVA Redback Generator is powered by a modern Electronically Fuel Injected (EFI) petrol engine, delivering precise performance and better fuel efficiency than traditional carburettor models.

Designed for the realities of travelling in Australia, the RB4.5 meets local EPA emission standards, giving you a cleaner, more sustainable power option. Whether you're going fully off-grid or just want a backup you can rely on, this generator gives you flexibility and independence.
Starting the RB4.5 is effortless with the included remote control, push-button start or manual recoil. Plus, it comes with a full range of accessories to help you maintain it properly, so it stays reliable trip after trip.
