Yet, how do you know which one is best jumper box for your car and what kind of money you need to get it?

What to Look for When Buying a Jump Starter Pack? – (and get the best for your car at the right price) 

There are 3 types of devices you can use to get your car back on the road. Each one has a different cost, and here we explain everything you need to get the one for your car without spending more.

Battery Chargers

These units charge your car battery and some do maintenance to it.

Some can jump start your car and need to be plugged to a wall AC outlet, so they are not portable.

Portable Jumper Boxes

These portable starter packs are lightweight and start your engine but don’t charge the battery nor maintain it.

They have a rechargeable internal battery so there is no need to plug them to any power source.

USB ports are available to charge small electronics like cameras, phones and drones.

Portable Power Stations

These units can power up your RV and potentially jump start or charge your car’s battery.

A PPS may be more than what you need if you just want to jump your car.

This website is dedicated to the portable battery jump boxes for cars and all the advice you’ll find here will refer to this type of jumper boosters.

Here is a comprehensive list of the things you want to check when choosing a car jumper.

Battery Type

There are two types of batteries when speaking about car jump packs:

  • Lead-acid: These are cheaper but have a shorter lifetime and are not as efficient as Lithium-ion jumpers.
  • Lithium jump starters: They are more expensive but smaller, lighter, and last longer than lead-acid jump starters. 

Most portable jumper boxes these days come with a Lithium-ion battery, so you’ll have a product that is safe to use, will last longer and is more portable.

peak Amps the jump start box can deliver

The amount of amps of your car’s battery is what gets the engine started every morning. The bigger the engine the more amps it will need to start.

Make sure to check your engine’s size so you get a battery jump pack with more than enough peak amps to start your car.

PEAK AMPS for gas vehicles

For every 1 liter of engine size, 61 Amps are needed. If you have a V8 5.8L RAM truck, it will need 353.8 Amps to get started.

PEAK AMPS for DIESEL vehicles

For every 1 liter of engine size, 122 Amps are needed. If you have a 6.1L truck, it will need 756.4 Amps to get started.

Battery Voltage rating

All vehicles use a battery of either 6, 12, or 24 volts. The jump starter you select must match the voltage of your battery.

Even if the voltage rating of your jumper box is bigger, it won’t work.

Most cars use 12 Volt batteries, so to jump start your car you need a 12V jump starter. If your vehicle uses a 6 or a 24 Volt battery, a 12 Volt battery booster will not jump start it.

Force Start Function

If the battery is extremely drained the emergency jump pack may not detect the battery and won’t supply any current. With a force start function, the jumper is forced to pass its juice to the flat dead battery to get it started.

Reverse polarity and spark protection

Jump starting a car is not difficult, yet some people don’t know the red cable goes to the positive terminal and the black goes to the negative one, and they connect these backwards.

This can damage your battery and other electronics of your car, so a portable jumper box with a reverse polarity protection will not supply current if the connection is not right.

Also, we all hate when the cables touch each other and sparks appear. A spark protection will avoid this.

Car jump starters should have other safety features such as overload protection. These features will help protect your vehicle’s battery and electrical system against damage.


If you have both gas and diesel engines, make sure to buy one that is compatible with both types.

Get your car back on the road in seconds using a jumper starter for car and without having to ask a stranger.
