What if you have a dead car battery and need to jump start your car? Can a Jackery portable power station do that? How much power do you need to jump start a car? In this post, we will answer these questions and explain whether a Jackery portable power station can jump start a car or not.
The short answer is no. A Jackery portable power station cannot jump start a car. Jump starting a car requires a large amount of peak power to turn over the engine, which is more than what a Jackery portable power station can provide. A Jackery portable power station is designed for powering small devices and appliances, not for jump starting a car.
How Much Power Do You Need To Jump Start A Car?
To understand why a Jackery portable power station cannot jump start a car, we need to understand how much power is needed to jump start a car. The power needed to jump start a car depends on several factors, such as:
- The engine size: The larger the engine, the more power it needs to start. For example, a 6L gasoline engine needs more power than a 2L gasoline engine.
- The battery condition: The older or weaker the battery, the more power it needs to start. For example, a battery that is low on charge or has sulfation needs more power than a battery that is fully charged or new.
- The weather condition: The colder the weather, the more power it needs to start. For example, a battery that is in freezing temperatures needs more power than a battery that is in warm temperatures.
The power needed to jump start a car is measured in two units: volts and amps. Volts are the electrical potential or pressure that pushes the current through the circuit. Amps are the electrical current or flow that delivers the energy to the device. The product of volts and amps is watts, which is the total amount of power.
To jump start a car, you need two things: enough volts and enough amps. The volts determine whether the current can reach the device, while the amps determine whether the current can deliver enough energy to the device.
Most cars have 12V batteries, which means they need 12V of electrical potential to start. However, 12V alone is not enough. You also need enough amps of electrical current to deliver enough energy to turn over the engine.
The amount of amps needed to jump start a car varies depending on the factors mentioned above, but generally speaking, you need at least 300 amps for a small engine (2L or less), at least 400 amps for a medium engine (2L to 4L), and at least 500 amps for a large engine (4L or more).
These are minimum values, and you may need more amps depending on your specific situation. For example, if your battery is very low or very cold, you may need up to 1000 amps or more to jump start your car.
How Much Power Can A Jackery Portable Power Station Provide?
Now that we know how much power is needed to jump start a car, let’s see how much power can a Jackery portable power station provide. Jackery has several models of portable power stations, ranging from 240Wh to 3000Wh in battery capacity and from 200W to 2000W in output power.
The output power of a Jackery portable power station is measured in watts, which is the product of volts and amps. For example, if a Jackery portable power station has an output of 200W at 12V, it means it can provide up to 16.67A of current (200W / 12V = 16.67A).
However, this output power is not constant or peak. It is only an average or rated value that indicates how much power the Jackery portable power station can provide under normal conditions and for continuous use. The actual output power may vary depending on several factors, such as:
- The battery level: The lower the battery level, the lower the output power. For example, if a Jackery portable power station has only 10% of battery left, it may not be able to provide its rated output power.
- The device load: The higher the device load, the lower the output power. For example, if a Jackery portable power station is powering multiple devices at once, it may not be able to provide its rated output power.
- The temperature condition: The higher the temperature, the lower the output power. For example, if a Jackery portable power station is exposed to high temperatures, it may not be able to provide its rated output power.
The peak output power of a Jackery portable power station is the maximum amount of power it can provide for a short period of time, usually a few seconds or minutes. The peak output power is usually higher than the rated output power, but it is not sustainable or reliable. The peak output power may also vary depending on the factors mentioned above.
The peak output power of a Jackery portable power station is not clearly stated in the product specifications, but it can be estimated by multiplying the rated output power by a factor of 1.5 to 2. For example, if a Jackery portable power station has a rated output of 200W at 12V, it may have a peak output of 300W to 400W at 12V.
Why Can’t A Jackery Portable Power Station Jump Start A Car?
Based on the information above, we can see why a Jackery portable power station cannot jump start a car. To jump start a car, you need at least 300 amps to 1000 amps of current at 12V, depending on your car’s engine size, battery condition, and weather condition. However, a Jackery portable power station can only provide up to 16.67 amps to 166.67 amps of current at 12V, depending on its model, battery level, device load, and temperature condition.
Even if we consider the peak output power of a Jackery portable power station, which may be higher than the rated output power by a factor of 1.5 to 2, it is still not enough to jump start a car. The peak output power of a Jackery portable power station may range from 300W to 4000W at 12V, which means it can only provide up to 25 amps to 333 amps of current at 12V.
Therefore, a Jackery portable power station cannot provide enough current to jump start a car. It may be able to charge your car battery slowly over time, but it cannot turn over your engine instantly. If you try to use your Jackery portable power station to jump start your car, you may damage your devices or cause safety hazards.
How To Jump Start A Car With A Portable Power Station?
If you want to jump start your car with a portable power station, you need to use a special device called a jump starter or a booster pack. A jump starter or a booster pack is a device that has a built-in battery and an inverter that can provide enough peak power and current to jump start your car.
A jump starter or a booster pack usually has two alligator clamps that can connect to your car’s battery terminals and deliver the necessary current to turn over your engine. It also has an input port that can connect to a wall outlet, a car cigarette lighter, or a solar panel and recharge its battery.
A jump starter or a booster pack is different from a Jackery portable power station in several ways:
- It has higher peak power and current: A jump starter or a booster pack can provide up to 1000W to 2000W of peak power and up to 500A to 1000A of peak current at 12V, which is enough to jump start most cars.
- It has lower battery capacity and output options: A jump starter or a booster pack usually has only around 50Wh to 100Wh of battery capacity and only one or two outputs (usually USB ports), which means it cannot power many devices or appliances for long.
- It has different safety features and design: A jump starter or a booster pack usually has some safety features and design elements that are specific for jump starting cars, such as reverse polarity protection, spark-proof clamps, LED lights, etc.
Conclusion
Jackery portable power stations are great devices that can provide you with reliable and green power for your outdoor adventures, home backup, and off-grid living. They have multiple outputs and inputs to charge your devices and appliances, and they can be recharged by wall outlets, car cigarette lighters, or solar panels.
