Heavy Duty Jump Starter with Air Compressor

Under Ideal ConditionsUpdated

Get the WOLFBOX MegaVolt16 Air for a diesel and the NOCO Boost Air for a gas truck or SUV. If your tires are 35 inches or taller, add a separate Viair compressor.

  • The fuel cap or engine badge says diesel: get the WOLFBOX MegaVolt16 Air. It's rated 3,000 A and for diesels up to 6 L, with a compressor that goes to 160 PSI.
  • You have a gas truck or SUV with a V8 and want a pack you can carry in the cab: get the NOCO Boost Air. NOCO rates it for gas engines up to 8.0 L, its compressor stops at the pressure you set, and it weighs 6.9 lb.
  • You have a gas V8 and the pack lives in the garage or the truck bed, where weight doesn't matter: get the DeWalt jump starter with compressor. It's a 1,600 A lead-acid pack that jumps up to a V8 and has a 120 PSI digital compressor. It weighs 17.5 lb, and DeWalt says to recharge it every 30 days in storage. If you'd rather carry less, get the NOCO above.
  • The sidewall of your tire measures 35 inches or more: get the Viair portable compressor rated for 37-inch tires and keep a jump pack from this list for the starting. A combo pack's built-in compressor is the wrong place to put that tire.
  • Your engine is a diesel over 6 L or a gas engine over 8 L: get the NOCO Boost X for the jump. At 4,250 A it's the pack for big engines. Add the Viair compressor from the bullet above for the tires.

Diesel gets the higher amp rating for a reason. Lectron's guideline, as quoted by CR, calls for at least 3,000 peak amps on a diesel. Makers don't share one scale, and NOCO rates its 2,000 A pack to diesels of 6.0 L on its own basis. If you're between two packs, take the higher rating. If your engine is smaller and you want a lighter pack, the best 4 in-1 jump starter with air compressor is the page for you.

Once the pack is chosen, tire pressure is the only number left to set. Fill to the proper cold tire pressure printed on the label in your driver's doorjamb, and never past the maximum molded on the tire. If you only need to fill tires and don't need a jump, the best portable air compressor is the page for you.

Jump-starting follows two sets of instructions: the pack maker's and your vehicle maker's. Read both before the first use.

Questions

Which heavy duty jump starter with air compressor is best for a diesel engine?

The WOLFBOX MegaVolt16 Air is the pick for a diesel. It is rated at 3,000 A and for diesels up to 6 L, and its compressor goes to 160 PSI. Diesels need a higher amp rating, and Lectron's guideline, as quoted by Consumer Reports, calls for at least 3,000 peak amps. If your diesel is over 6 L, get the NOCO Boost X for the jump instead.

Which jump starter with a built-in compressor suits a gas truck or SUV?

The NOCO Boost Air is the best fit for a gas truck or SUV when you want a pack you can carry in the cab. NOCO rates it for gas engines up to 8.0 L, its compressor stops at the pressure you set, and it weighs 6.9 lb. If the pack stays in a garage or truck bed, the DeWalt is an option at 17.5 lb.

Can a combo jump starter air compressor fill tires that are 35 inches or taller?

No, a combo pack's built-in compressor is the wrong tool for tires that measure 35 inches or more. Buy a separate Viair portable compressor rated for 37-inch tires, and keep a jump pack from the list for starting the engine. This pairing also works with the NOCO Boost X if your engine is a diesel over 6 L or a gas engine over 8 L.

What tire pressure should I fill to with a jump starter air compressor?

Fill to the proper cold tire pressure printed on the label in your driver's doorjamb. Once you have chosen a pack, tire pressure is the only number left to set. Never inflate past the maximum pressure molded on the tire itself, even if the label number is lower or the compressor can keep going.
