AHAHAHAHAHAHAHAHAHAHAHA! I don't believe a word of it! Like booster cable
replacements that plug into the cigarette lighter! Your starter requires
somewhere between 80 -400 amps to crank your engine. There is no way
you could get this much current out of a D cell, or through the 20gauge
wire these boostr cable replacers use!!!!

NOTE the current range is a guess, but we once measured a 3/4ton pickup at
about 350amps!
