Long enough to power electricity
That would depend on too many things that are no listed. Need to know what the desired temperature is.. What the BTU rating of the heater is, what the efficiency rating is, what the R value of the structure is.
Days.
Most do not last very long. Most last less than 5 minutes and many less than a minute. However, duriations over 30 minutes are not unheard of.

A cylinder? A cylinder is still a cylinder regardless of how long it is.

An ML6 oxygen cylinder, when "charged" to normal pressures, holds 170 liters of oxygen. How long that will last depends on a number of factors. If the flow is set to 2 liters per minute continuous then it will last less than 1 and 1/2 hours. If an oxygen conserving device is used (they give the gas in pluses when breaths are taken) it can last over 4 hours.
It can vary, but wind-up radios can last up to an hour or two on one full wind-up.
