Stupid question

[hondatrikesrule22]

I am buying a motorcycle from someone, and he says I need plugs, some gas, and a jumper box.What is a jumper box? thanx

If I had to guess I would say he means one of those portable battery jump start packs. They are worth their weight in gold. No need for a second vehicle and no jumper cables to untangle.
