ECOFLOW RIVER 2 256Wh Mobile Power Station

This device is a premium option compared to a DIY converter setup in terms of capacity, but it's a very convenient all-in-one solution.

You can power around 50-70W (e.g. a good NUC or an APU using desktop) for just over 2 hours with this, and with 1h charging you can just about get by with loadshedding. But, when you don't need it for one thing it's tiny so easy to move around. If you use a laptop with decent battery instead of a desktop, this will allow you to work all day.

Time will tell to see if this thing survives 2023 - through no fault of its own at this rate.

I am both happy with the service I received from Wootware, and also the performance of the EcoFlow Inverter. While the maximum wattage rating is not very high, the device has a "boost mode" which allows double the wattage for short spikes and as a unit does exactly what I expected and required of it. Decent buy.
