Naio .... "so I could avoid a tarpaulin heavy electric blanket" was never stated by me. Someone else earlier in this discussion???
Electric blankets have improved vastly ... including feeding the blanket with DC (direct current) power instead of AC power. Some scientific evidence may indicate that DC current is safer to be used close to the human body than AC current .... but after years the jury still seems to be out on any real danger from use of electric blankets in general.
My current electric blanket uses 18V DC power at 3.5 amps of current. I assume that this 3.5 amps of 18V power applies whenever the blanket's control is set to it's maximum heat value of "10". Since I usually have it's control set only between a setting of "1" and "3", probably way less than 3.5 amps of 18V DC power is being consumed. This means that an electric blanket like mine could be a viable warming solution for no-hookup sleeping in an RV if one's battery bank has a capacity of, say, 200 amp hours or greater. Of course the "brick" for the electric blanket that converts incoming 120V AC power into 18V DC probably needs to powered from RV batteries through a pure sine wave inverter. Ideally, probably a direct DC powered electric blanket should be used in RV's for maximum energy efficiency during non-hookup camping.
