How many amps needed in portable jump starter

Have you ever encountered such a situation, when you parked the car in the garage for a few months, and then started the car and found that the battery is dead and unable to start. At this time a jump starter is undoubtedly the best emergency tool.

So, how many amperes of battery starter do you need? Let's take a look at a few important factors to choose to buy a battery jump starter.

  • Vehicle engine
  • Vehicle age
  • Operation environment

    Simple choices

    If you need to purchase a jump starter quickly. You can choose according to the table below.






    1500A 254*142*103MM/1.75KG Up to Gasoline 7.0L / Diesel 4.5L


    2000A 254*142*103MM/1.77KG Up to Gasoline 8.0L / Diesel 6.0L


    2500A 254*142*103MM/1.85KG Up to Gasoline 8.5L / Diesel 6.5L

    Vehicle Engine Size

    As indicated by the chart above, vehicle size does impact your decision on which battery jump starter is right for your car.

    Common sense would tell you that the larger the vehicle the more powerful the jump starter needs to be.

    A big V8 motor will take more to turn over than a smaller 4 cylinder.

    Your owner manual or a quick google search of your vehicle will tell you what size engine you have.

    To put this in perspective. Your standard Toyota Corolla will need about 150 cold-cranking amps to get jumped. On the other hand, a Chevy Suburban will require around 600-800 cold-cranking amps to get started.

    However,  vehicle size is not the only factor that needs to be taken into consideration.

    Vehicle Age

    In addition to the vehicle size, the vehicle’s age needs to be factored in. Over the years parts wear down and don’t function quite as well as they used to.

    In addition, technology is advancing all the time. This is true with car batteries as well, so a newer battery in a newer car will not require as much power as an older vehicle.

    A good rule of thumb is to have a battery jump starter that will have the power to jump-start your oldest and largest vehicle.

    For cars that have been used for a longer time, the car’s battery will be older and the starting current will be larger.


    Operation Environment

    This is a very important factor too. Where do you drive? Are the winter months extremely cold?

    If so, you need to make sure that your battery jump starter is up to the task of jump-starting your car. For instance, If you are going on a road trip, do some research ahead of time. If you are traveling to a cold climate; have a battery jump starter that will work in that climate. This is especially true if you intend on leaving your battery jump starter in the car.

    The extra power in the battery jump-starter will not hurt the vehicle when you are in a warmer climate. Be prepared for the worst conditions that you will be in.

    If you often use it in a low-temperature environment, the voltage of the starter will drop rapidly, so determine the operating temperature range of the jump starter.
