Voilamart Heavy Duty Battery Jumper Cable 2 Gauge 20Ft 1200AMP Booster Cables for Cars Trucks

Why it's worth it

Voilamart's 2-gauge set uses 12mm-thick conductors rated for 1,200 amps, which is more than enough for large gas engines and most diesels. It gives up five feet of reach compared with our top pick, but it's easier to store and handle.

Two-gauge is the sweet spot for most trucks and SUVs. You get most of the current capacity of a 1-gauge cable in a bundle that's noticeably easier to coil and stow. Voilamart rates these at 1,200 amps through 12mm-thick conductors. That's ample for a V8, and the listing covers petrol and diesel engines up to 9500cc.

The insulation is built for what's actually under a hood. PVC that resists heat, oil and acid matters because cables get dragged across engine bays and set down on whatever's nearby. All-insulated clamp handles are the other detail worth having, especially if you jump-start rarely and aren't confident about where your hands are going.
