Can a 12 volt portable jump starter, such as a NOCO Boost X GBX45 1250A Portable Lithium Jump Starter, be used to start a 1951 Chevrolet with a 6 volt system without damage to the electrical system?

Thanks. Can the leads on the starter connect directly to the battery posts?

Many portable jump boxes have a switch to activate the power. On those you can hook up the cables and then turn on the switch to start and them switch off.

To make it even handier get the one with the little built in compressor. Out on a tour it is really handy to use on yours and your fellow members tires or as a jump start.

Found this dialogue when searching the forums for an answer to my own question:

Do I gain anything (single person boost) by putting a "step-down" block (intended to protect 6-volt accessories from 12-volt battery) between the 12-volt NOCO booster and the starter?

New battery, '31 is recently running after 15 years garage stored. I had trouble starting after it sat for a few hours at a local "cruise-in". I didn't flip the battery breaker I recently installed(!). Want to be able to venture out with battery boost when I run into the problem gmharlow/Greasemonkey outlined.

I'm confused. Are you asking a question? If so you should start your own thread rather than piggyback on this one.
