Default RAC Portable Power Station, need DC adaptor spec

On 12/2/2010 2:01 AM Adrian C spake thus:

A neighbour has dropped in with his discharged and dead "RAC Portable
Power Station and Engine Starter" which he obtained without the
necessary DC charger. The starter is a dayglo orange heavy thing with a
handle and says it can crank 400 Amps.


I'm surprised nobody has mentioned this yet in this thread, but aren't
those claims for how much current these things will deliver a lot of BS?

I first saw one of these power units a couple weeks ago, when my
neighbor used his to get my van started after he borrowed it and the
battery started going dead. He used it twice, successfully, to
jump-start my half-dead battery. So they do work, apparently. But his
was similarly marked (I think 300 amps). Is there any way that such a
small lead-acid battery could deliver this much juice? I'm skeptical.
