Best 4 In-1 Jump Starter with Air Compressor

Under Ideal ConditionsUpdated

The jump decides this purchase, so match the pack to your engine. For the best jump starter with air compressor on a gas engine of 3.0 L or smaller, we'd get the AstroAI S8 Air. For a pickup, a bigger SUV or any diesel, we'd get the WOLFBOX MegaVolt16 Air. Either one carries a built-in compressor and a USB port, so it jumps the car, fills the tires and charges your phone from one battery. Your owner's manual lists your engine size.

Best Lithium Battery Jump Starter with Air Compressor

The best lithium battery jump starter with air compressor is the one rated for your engine, so find your branch and click it.

  • Your owner's manual lists a gas engine of 3.0 L or smaller, and 1,500 A with a 150 PSI compressor covers it: AstroAI S8 Air.
  • Your vehicle is a diesel or has a gas engine bigger than 3.0 L, and you want 3,000 A with a 160 PSI compressor: WOLFBOX MegaVolt16 Air.
  • Your engine is a gas V6 or V8 and the far tires sit out of reach of a short hose, so you want a lithium-ion pack with a long air hose and NOCO's 2,000 A rating for gas up to 8.0 L: NOCO Boost Air.
  • Your trunk has room for a 17.5 lb pack, your engine is up to a V8, and you want sealed lead-acid instead of lithium: DeWalt's 1600A jump starter with compressor.
  • You air up 35-inch off-road tires: keep a jump pack from this list for the jump, and add a dedicated compressor rated for tires up to 37 inches for the air: Viair 400P-A.

Engine ratings come from the makers and don't share one scale. Lectron's guideline, as Consumer Reports quotes it, puts engines of 2.0 to 3.0 L at 1,200 to 2,000 peak amps, engines over 3.0 L at 2,000 to 3,000, and diesels at 3,000 or more. That puts the S8 Air's 1,500 A inside the range for 3.0 L and under, and the MegaVolt16 Air's 3,000 A at the diesel line. NOCO rates the Boost Air on a different basis. If your engine sits between two sizes, take the larger pack. If you already own a jump pack and only need air for tires, the best portable air compressor is the page for you.

Your car sits in summer sun or winter frost

Keep the pack in the house, not the glovebox. Lithium-ion batteries don't belong in hot vehicles, and a summer car interior can exceed 140°F.

In winter, a pack stored at 20°F has less jump-starting power than one at 60°F, so carry it out when you need it. Lithium charges only at or above 32°F, so keep the pack above that before charging. Recharge about every 3 months, and monthly if the pack rides in a cold car.

At 0°F, with the car and the pack both cold, none of the packs in Consumer Reports' tests could start weak or dead batteries. Store yours warm and expect the jump to be harder in a hard frost.

Heavy Duty Jump Starter with Air Compressor

The best heavy duty jump starter with air compressor for a pickup, SUV or diesel is the WOLFBOX MegaVolt16 Air, which GearLab scored 77 of 100.

GearLab lists it for gas engines up to 8 L and diesels up to 6 L on a 3,000 A rating. It passed a three-start rapid test, and it added 5 PSI to the 275/70R18 tires on an F-150 in about 3 minutes. It's also a 4-in-1 jump starter with air compressor, with a 400 lm light and a USB-C power bank rated 65 W in 5.3 lb, which is why we'd call it the best 4 in-1 jump starter with air compressor for a truck.

Compare heavy-duty packs on engine rating, not headline amps. Peak amps measure a burst of a few seconds, and Clore lists 1,700 peak amps next to 425 cranking amps on its JNCAIR combo, so the two numbers describe different things.

Consumer Reports' buying guidance says 400 to 500 CCA should suffice for passenger cars, SUVs and pickups. CCA, cold cranking amps, is a battery test: SAE J537 has a battery deliver its rated current at -18°C for 30 seconds. Power-Sonic says no true standard exists for lithium CCA, so each maker sets its own method. Read a pack's CCA as the maker's number, and choose on the engine rating.

If you want sealed lead-acid for a V8, DeWalt's 1600A jump starter with compressor was Bob Vila's Best Overall. Its testers timed bike tires at about 20 seconds and a large pickup tire at about 5 minutes.

Skip the Stanley jump starter with air compressor. It's a sealed lead-acid pack rated 1,000 A, it delivered less current under load than its rivals, and GearLab rates it the lowest of the 13.

Whichever pack you buy, set the pressure from the label on your driver's doorjamb. A 160 PSI ceiling is the pump's limit, and the tire's sidewall figure is only the tire's maximum.

AstroAI Jump Starter with Air Compressor

AstroAI's jump starter with air compressor is the AstroAI S8 Air, a 2.4 lb pack with a 10,000 mAh battery and an operating range of -4 to 140°F.

A review of the AstroAI jump starter with air compressor timed the S8 Air from 0 to 36 PSI in just under six minutes. The reviewer also found 25 to 50 percent of the battery left after several jumps, top-offs and a phone charge. AstroAI's figures are 21 inflations from 28 to 36 PSI and 20 jump starts per charge.

AstroAI jump starter instructions start with the manual, which the reviewer says advises letting the unit cool after 10 minutes of continuous use. Jump the car the way AstroAI's manual and your owner's manual direct.

The AstroAI L7 has no jump function, so skip it if you want both jobs. The L4 was the slowest inflator by a large margin in Car and Driver's July 2024 test.

Questions

Which 4-in-1 jump starter with air compressor is best for a pickup, large SUV, or diesel?

The WOLFBOX MegaVolt16 Air is the pick for a pickup, a bigger SUV, or any diesel. GearLab scored it 77 of 100 and lists it for gas engines up to 8 L and diesels up to 6 L on a 3,000 A rating. It passed a three-start rapid test and added 5 PSI to F-150 tires in about 3 minutes.

Which jump starter with air compressor suits a gas engine of 3.0 L or smaller?

The AstroAI S8 Air is the pick for a gas engine of 3.0 L or smaller. It is a 2.4 lb pack with a 10,000 mAh battery and a 1,500 A rating, which sits inside Lectron's guideline range of 1,200 to 2,000 peak amps for engines of 2.0 to 3.0 L. Your owner's manual lists your engine size.

How should I compare jump starters with air compressors, peak amps or engine rating?

Compare jump starters on engine rating, not headline peak amps. Peak amps measure a burst of a few seconds, and Clore lists 1,700 peak amps next to 425 cranking amps on its JNCAIR combo, so the two numbers describe different things. Power-Sonic says no true standard exists for lithium CCA, so read a maker's CCA as its own number. If your engine sits between two sizes, take the larger pack.

Where should I store a lithium jump starter with air compressor?

Store the pack in the house, not the glovebox. Lithium-ion batteries don't belong in hot vehicles, and a summer car interior can exceed 140°F. A pack stored at 20°F has less jump-starting power than one at 60°F, and lithium charges only at or above 32°F. Recharge about every 3 months, or monthly if the pack rides in a cold car.

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

Set the pressure from the label on your driver's doorjamb, not from the tire sidewall. The sidewall figure is only the tire's maximum. A 160 PSI ceiling on a compressor is the pump's limit, not a target, so the doorjamb label is the number to follow whichever pack you buy.

Is the Stanley jump starter with air compressor worth buying?

No, the draft recommends skipping the Stanley jump starter with air compressor. It is a sealed lead-acid pack rated 1,000 A, and it delivered less current under load than its rivals. GearLab rates it the lowest of the 13 packs it covered, so a different pack from this list is the better choice.
