EcoFlow Advanced Kit review: Power your whole house with batteries
Roundaboutnow has put much of the problem with this piece of technobabble clearly and rather too kindly. I would add this other quote:
“With a 3,600Wh battery inside, the Delta Pro can last up to one day and output 12V of power. It can be fully charged in roughly 2.7 hours — which is good statistically since you get nearly 12x the amount of usage out of the power station.”
What can I say about this? Maybe someone who understood the basic physics and the units used would have been a better choice to write this article? Even after reading the whole piece twice, a quite excruciating experience, I still don’t know, even though he states that the battery holds 3.6 kW.h of energy, how many hours or minutes it could sustain an ac load of say 1 kW. No, it’s not 3.6 hours because we don’t know how efficient it is at converting dc to ac and at what level of charge the electronics will cut off or fall over. Without this basic knowledge, it’s really hard to work out how useful this thing is.On balance a small Honda generator and 10 litres of petrol is much more useful for emergency power and MUCH easier to carry, though you do need to put it outside. Remember that 1kg of hydrocarbon fuel stores as much energy as about 9 kg of battery and even allowing for the much lower conversion efficiency you are still streets ahead- and can refill it from a jerrycan indefinitely. -

M1 MacBook Air review: nearly as transformative as the original
Sorry to be pedantic but the m1 macbook air is 60% faster in single core and 200% faster in multicore or if you prefer 160% and 300% as fast. To be be 160% faster it needs to have a speed 2.6 times that of the intel version. Great machine and a great leap forward- once they sort out the number of ports it will be truly unchallengeable choice unless you need to run windows, and even that might well be solved. -
