The best jump starter for most pickup trucks is the SAFEMATE SM2000 PRO. It's rated for gas engines up to 10.0L and diesel engines up to 8.0L, so one pack covers everything from a 5.0L gas V8 to a 6.7L diesel. Driving a heavy-duty diesel in hard winters or on the job? Step up to the SM3000 PRO. Have a gas pickup and want a smaller pack? The SM1500 is enough.

Which Jump Starter Should You Buy for Your Pickup?

Find your truck in the table and you have your answer.

Your pickup	Our pick	Rated for	Why it fits
Gas pickup with an engine up to 8.0L	SM1500 (1,500A)	Gas up to 8.0L, diesel up to 6.0L	Covers the engines in most gas pickups
Most pickups, gas or diesel, including 6.7L diesels	SM2000 PRO (2,000A)	Gas up to 10.0L, diesel up to 8.0L	One pack for any pickup you're likely to own
Heavy-duty diesel, work trucks, cold winters	SM3000 PRO (3,000A)	Gas up to 12.0L, diesel up to 10.0L	The most headroom in the lineup, plus a 74Wh battery

Not sure which is yours? Look up your engine size and fuel type. Those two facts decide it.

Why Is the SM2000 PRO the Best Pick for Most Pickups?

It covers both fuels with room to spare. A 6.7L diesel is the biggest engine many pickup owners will ever have, and the SM2000 PRO is rated for diesels up to 8.0L. A 5.0L or 6.2L gas V8 sits well inside its 10.0L gas rating. So you can buy once and keep it in the truck, whichever engine you have now or buy next.

The details:

2,000A peak current and a 59.2Wh battery.
Gas up to 10.0L, diesel up to 8.0L.
Operating range of -4°F to 144°F (-20°C to 60°C).
Two-year warranty, with technical support that replies within 24 hours.
Tested and certified to UL, GS, ETL, CE, and FCC standards, according to SAFEMATE.

Wondering if 2,000 amps is really enough? For most drivers, yes. Is a 2000 Amp Jump Starter Enough? explains why a bigger number doesn't always mean a better product.

When Should You Choose the SM3000 PRO Instead?

Pick the SM3000 PRO if you run a heavy-duty diesel, work the truck hard, or live where winter mornings are brutal. It's rated for diesels up to 10.0L and gas engines up to 12.0L, and it has a bigger 74Wh battery.

Both the SM2000 PRO and the SM3000 PRO cover a 6.7L diesel. The SM3000 PRO just gives you more headroom for the toughest jobs. If your truck isn't in that category, save the money and go with the SM2000 PRO.

When Is the SM1500 Enough?

Choose the SM1500 for a gas pickup with an engine up to 8.0L. It's also rated for diesels up to 6.0L, which covers smaller diesel trucks.

Check your exact engine size first. A V6 badge doesn't tell you how hard an engine is to crank, and the same V6 can be a different job in a different truck.

If you'd also like to air up tires, the SM1500-AIR adds an air compressor to a 1,500A jump starter rated for 8.0L gas and 6.0L diesel engines.

Why Do Diesel Pickups Need More Starting Power Than Gas Pickups?

A diesel lights its fuel with the heat of compression, so the starter has to spin a heavy engine fast. Glow plugs or an intake heater may also draw power before the engine cranks. On top of that, thick cold oil makes the engine harder to turn.

That's why a diesel is a tougher job than a gas engine of similar size, and why a jump starter can have a lower diesel rating than its gas rating. Always compare the diesel number to your engine, not the gas number.

Does a Diesel Truck With Two Batteries Need a 24V Jump Starter?

No. Most pickups with two batteries use two 12V batteries wired in parallel. That's still a 12V system, so a 12V jump starter is the right kind. You also only need one pack, not two. If you're not sure how your truck is wired, your owner's manual shows the battery setup and the marked jump points.

What About Peak Amps and CCA?

Peak amps are a jump starter's advertised top current. CCA, or cold cranking amps, is a rating for car batteries. It's set by the Battery Council International (BCI) and measures what a fully charged 12V battery can supply for 30 seconds at 0°F while staying above 7.2 volts. The two are measured differently, so you can't convert one into the other.

In practice, that means an 800-CCA battery doesn't need an “800A” jump starter. Pick by engine size and fuel type, as in the table above. What Amp Jump Starter Do I Need? A Vehicle-by-Vehicle Guide shows how that works for different vehicles.

How Does Cold Weather Change Things?

Cold weather makes starting harder for the truck and weaker for the battery. AAA notes that low temperatures reduce battery performance and thicken the oil. An AAA spokesperson told CBS Philadelphia that a battery is about 35% weaker at 32°F and loses roughly 60% of its strength at 0°F.

Two habits help. Keep the jump starter charged, and don't leave it exposed to extreme heat or cold in the cab. Can You Leave a Jump Starter in Your Car? A Safe Storage Guide covers how. If your truck already won't start on a cold morning, Car Won’t Start in Winter? helps you read the signs.

How Do You Jump Start a Pickup With a Portable Jump Starter?

Park safely, set the parking brake, and turn off lights and other loads.
Check that the jump starter is charged and that the battery isn't frozen, leaking, or swollen.
Connect the clamps to the marked positive and ground points, red to positive and black to negative. Your owner's manual shows where they are.
Turn the jump starter on. On a diesel, wait for the preheat light to go off.
Start the engine, then disconnect the clamps and recharge the jump starter.

Frequently Asked Questions

What is the best jump starter for a pickup truck?

For most pickups, it's the SAFEMATE SM2000 PRO. It's rated for gas engines up to 10.0L and diesel engines up to 8.0L. Choose the SM3000 PRO for heavy-duty diesels and hard use, or the SM1500 for gas pickups up to 8.0L.

Is a 2,000-amp jump starter enough for a diesel pickup?

Yes, for most. The SM2000 PRO is rated for diesel engines up to 8.0L, which covers a 6.7L diesel. If you run a heavy-duty diesel in very cold weather or use it for work, the SM3000 PRO gives you more headroom.

Can one jump starter work on both gas and diesel trucks?

Yes, if it's rated for both. Check the separate gas and diesel limits against each engine. If you share one pack across several trucks, size it for the biggest engine.

Will a 3,000-amp jump starter damage a gas pickup?

No. The amp rating is the most the pack can deliver, not the current it forces into your truck. Your truck's starter only draws what it needs. Just match the voltage (12V) and connect the clamps correctly.

Do I need two jump starters for a truck with two batteries?

No. Two 12V batteries wired in parallel act as one 12V system, and one properly rated jump starter can start it.

Can I jump start a completely dead battery?

Often, yes. SAFEMATE jump starters have a Boost Start mode for car batteries so drained that the unit can't detect them. You press and hold the power button for more than 5 seconds with the clamps connected. Boost Start turns off the short-circuit and reverse-polarity protections, so double-check the clamps first. SAFEMATE's troubleshooting page has the steps. Don't jump a frozen or damaged battery.

Ready to Choose?

For most pickups, get the SM2000 PRO. For a heavy-duty diesel, get the SM3000 PRO. For a smaller gas truck, the SM1500 is enough. Want to see them side by side? Compare the Differences Between the Models, or browse the full SAFEMATE jump starter collection.
