This thing packs a punch. Couldn't be happier with this jump box. Stores nicely in included pouch.

I have a ford econoline 2004 model which is basically the same drivetrain and engine as an f650 with a triton v10. Easily powered up two v8 on 1 charge. I get a dozen or so jumps to my toyota camry and near that with the full size tundra.

Light, much lighter than previous jump start boxes i've owned. Has not needed to be recharged after 4 jumps. Still shows full led status after each jump but i plugged it into charge anyway.

About 1 year new duralast gold battery became depleted, due to a string of single digit temperatures at night. It smells like it burnt up.
