Portable Battery Jump Starter

Don't Wait Until You're Stranded to Wish You Had One

A dead battery can leave you stuck at home, at work or miles from anyone who can help. A portable battery jump starter gives you a way to get your vehicle running again without needing another car.

Why Carry One? ↓

One of Our Favorite Things to Keep in a Vehicle

Jumper cables have been around forever, and they're still useful. But they have one major limitation: you need another vehicle and another person willing to help.

That's why we're big fans of the modern portable battery jump starter. Charge it, keep it in the vehicle, and when a weak battery leaves you stranded, you may be able to get yourself moving again without waiting for a stranger, friend or tow truck.

It's the kind of product you can carry for months without thinking about it — right up until the day you really need it.

Why Carry a Portable Jump Starter?

For us, the biggest advantage isn't horsepower, gadgets or flashy features. It's independence when your battery lets you down.

🚗 No Second Vehicle Required

Traditional jumper cables require a donor vehicle. A charged portable unit is designed to provide starting assistance on its own.

🌙 Useful When Nobody Is Around

A dead battery doesn't always happen in a convenient parking lot. Having your own starting power can be especially useful at night or in less-traveled locations.

🧰 Compact Emergency Gear

Modern units can fit in a trunk, cargo area or vehicle emergency kit without taking up much room.

👨‍👩‍👧 Useful for More Than Your Car

A jump starter may help you assist a family member or another driver with a compatible vehicle when their battery is weak.

How to Use a Portable Battery Jump Starter

Always follow the instructions supplied with your particular jump starter and your vehicle owner's manual. Connection procedures and safety features can vary by model.

1

Turn the Vehicle Off

Switch off the ignition and unnecessary electrical accessories before connecting the jump starter.

2

Find the Correct Connection Points

Locate the positive and negative battery terminals or the designated remote jump-starting points specified by your vehicle manufacturer.

3

Connect the Clamps as Directed

Follow the jump starter manufacturer's instructions for connecting the positive and negative clamps. Never guess about polarity.

4

Activate the Jump Starter

Some units operate automatically while others require a power or boost function. Follow the instructions for your particular model.

5

Start the Vehicle

Crank the engine according to the jump starter's recommended procedure. Avoid repeated long cranking attempts that can overheat equipment.

6

Disconnect and Recharge

Once the vehicle is running, disconnect the unit according to its instructions. Recharge the jump starter afterward so it's ready for the next emergency.

⚠ Battery Safety Matters

Do not attempt to jump-start a battery that is visibly damaged, leaking or frozen. Keep sparks and flames away from batteries, protect your eyes, and follow both the vehicle and jump-starter manufacturer's instructions.

Portable Jump Starter vs. Jumper Cables

Both can belong in your roadside-emergency toolbox, but they solve the same problem in different ways.

Portable Battery Jump Starter

  • Doesn't normally require a second vehicle
  • Compact and easy to store
  • Can be used when you're alone
  • Must be kept adequately charged
  • Must be suitable for your vehicle and engine

Traditional Jumper Cables

  • Simple and inexpensive
  • No internal battery to recharge
  • Usually require another suitable vehicle
  • Require safe connection between two vehicles
  • Still an excellent backup to carry

CarDudes Tip

If you have room, carrying both a portable jump starter and a good set of jumper cables gives you more than one option when battery trouble strikes.

What to Look for When Buying a Jump Starter

Don't choose one simply because the box shows the biggest number. Make sure the unit is appropriate for the vehicle you expect it to start.

Engine Compatibility

Check the manufacturer's recommended gasoline and diesel engine sizes for the unit.

Starting Capability

Compare the manufacturer's starting specifications with the needs of your vehicle rather than relying on advertising alone.

Safety Protection

Look for documented safety features such as reverse-polarity or improper-connection protection.

Clamp Quality

Good clamps and durable cables matter because they provide the physical connection between the starter and vehicle.

Size & Storage

Choose a unit you can realistically keep in the vehicle along with its cables and accessories.

Recharge Method

Know how the unit is recharged and periodically verify that it still has enough charge to be useful.

Why We Like NOCO Portable Jump Starters

NOCO's portable Boost line is one example of the compact lithium jump starters that made us fans of this type of roadside tool in the first place.

Choose the Right NOCO for Your Vehicle

NOCO offers different Boost models for different engine sizes and starting requirements. Check the current specifications and choose a unit rated for the vehicle you plan to use it with.

The Part People Forget: Keep It Charged

A portable battery jump starter isn't much help if you discover it has a dead internal battery at the same time your car does.

Check It Periodically

Follow the manufacturer's recommendations for checking the charge level and recharging the unit during storage.

Recharge After Use

If you've used the jump starter, recharge it instead of tossing it back into the trunk and forgetting about it.

Watch Extreme Temperatures

Storage temperature can affect batteries. Follow the manufacturer's storage guidance, especially during very hot or cold weather.

Inspect the Equipment

Periodically look over the unit, cables and clamps for damage or other conditions that could make the equipment unsafe to use.

If the Car Starts, Are You Finished?

Not necessarily. A jump starter can get the engine running, but it doesn't explain why the battery went dead.

Find the Cause of the Dead Battery

The battery may simply have been discharged because lights or another accessory were left on. But repeated dead-battery problems can also point to an aging battery, charging-system trouble, an electrical draw or another issue that needs diagnosis.

If the vehicle repeatedly needs a jump start, don't treat the portable starter as the repair. Have the battery and charging system checked.

The CarDudes Roadside Rule

The best emergency tool is the one you already have with you when the problem happens. Keep a properly sized portable battery jump starter charged, know how to use it before you're stranded, and keep the instructions with the unit.
