That’s some good diligence!

It looks like the ecoflow values are lower:

inchcalculator.com/…/kilowatt-to-btu-per-hour/

Since one kilowatt is equal to 3,412.14245 btu per hour

30 KWh/day x 365 days x 3,412 Btu/KWh = 37,361,400 Btu

Which is half the value I found for 2015. Does ecoflow have more current data and houses are twice as efficient? Maybe. They’re also trying to sell something, so maybe it’s based on data from their products. They don’t mention where they got it from.

The welovecycling conversion is off by 1000 (maybe the kilocalorie threw them off?)

www.inchcalculator.com/…/joule-to-kilocalorie/

Since one kilocalorie is equal to 4,184 joules

1 kcal = 4,184 J so 1 J = 1/4,184 kcal = 0.00023900573613 kcal

Otherwise, your math was right, just off by 3 zeros, so a household is more like 3.6 bagels per hour.

The nist site also doesn’t specify a unit of time, but if it is 20 watts/hour (Wh) we’d only need to move it 3 places for KWh, or 0.020 KWh.

Too many conversions can introduce errors, so we can go from KWh to kcal directly:

inchcalculator.com/…/kilowatt-to-kilocalorie-per-…

Since one kilowatt is equal to 860.420815 kilocalories per hour

0.020 KWh x 860 kcalh/KWh = 17.2 kcalh

Which, yeah, is not much of a bagel per hour. Keep in mind that the daily recommended calories for an average adult is 2000 kcal.

All in all, this was a fun thought experiment, so thanks for looking into it further!
