Dynamic: The Warehouse have an 800w inverter generator on clearance for $300 - http://www.thewarehouse.co.nz/red/catalog/product/Inverter-Generator-800W?SKU=1697039 .
I bought one of these a year ago and fire it up every 2 months for half an hour to blow out the cobwebs. Easy to start every time. Very quiet. Not the gruntiest but will easily keep the fridge cold in an outage and run a computer with its high quality output.
I paid $400 for mine on an 'introductory special' that said they would normally be $800.
Thanks for this - I was thinking of purchasing one a year or so back (when we moved to UFB with VOIP), and again noticed this one in my local TWH a couple of weeks ago. What stopped me getting one a year back was the idea to get one powerful enough to run a microwave (could be very useful in a civil emergency, I thought!). This one states 800W: would it run a microwave on a medium heat level, provided the power usage on the selected setting was below 800W? And I assume it'll be adequate to run the laptop, ONT and modem (even if not all three at the same time)? (The aim is to provide a longer-lasting power supply than a UPS.) Cheers.
