Key points for selecting a best portable jump starter

Emergency start power supplies (jump starters) for vehicles can be used not only as regular power banks but, more importantly, for jump-starting vehicles when your car battery is dead, making them highly practical tools to have on hand. If you find yourself in a situation where you need to boost a car, a reliable jump starter can be a lifesaver. But with so many options on the market, how can you choose a suitable jump starter for your needs? Here, AMPROAD shares with you the key points that need to be paid attention to when selecting a jump starter.

  1. Starting Current

The starting current is the parameter most directly related to the performance of an emergency power source. Please note that this refers to the starting current, not the peak current. The higher this value, the greater the ability for how to boost a car and start vehicles with dead batteries. Currently, mainstream products on the market generally have a starting current of around 200-500A. Under normal conditions, jump-starting vehicles with engine displacements of 4.0L to 6.0L or less is usually not a problem. However, if you plan to use the vehicle booster pack in cold environments, its effectiveness may be reduced, so it is advisable to choose a product with a higher starting current rating.

  1. Battery Cell Configuration

Currently, most similar battery jump starters on the market use combinations of 3 and 4 battery cells in series. We recommend choosing products with 4 battery cells. This is because, under the same starting current, a 4-cell configuration can reduce the overall size of the power bank, making the product more compact and portable. Typically, product specifications do not mention the battery cell configuration, so you may need to consult with customer service for specific details.

  1. Input and Output

Since jump starters can also be used as power banks, their input and output capabilities are also important factors to consider, focusing on speed and interfaces. In terms of speed, it is recommended to choose products that support fast charging, which will quickly replenish the power bank's capacity and provide fast charging for other devices. Regarding interfaces, it is advisable to select products with both USB Type-C and USB Type-A ports, making them more versatile and compatible with a wide range of devices.

  1. Battery Capacity

Because you need to ensure a higher jump start current for boosting a car, the battery capacity of these jump starter products is usually above 10,000mAh. As a power bank, higher battery capacity is always better, and greater capacity allows for more jump-starts or charges for other devices. However, these products are primarily intended for emergency use, and the demand for extremely high battery capacity is not particularly high. We recommend that you choose based on your specific needs, balancing battery capacity with portability and weight.

  1. Safety Features

When dealing with high-voltage electrical systems like those in vehicles, safety should be a top priority. Look for jump starter that incorporate safety features such as reverse polarity protection, which prevents damage to the device or your vehicle's electrical system if the positive and negative cables are connected incorrectly. Some jump starters also include temperature monitoring and automatic shutoff mechanisms to prevent overheating or other potential hazards.

  1. Durability and Reliability

A jump starter is an investment in peace of mind and preparedness, so you'll want to choose a product from a reputable brand known for durability and reliability. Look for jump starters with robust, well-constructed casings that can withstand the rigors of outdoor use and harsh environments. Additionally, consider models with long warranty periods, which can provide added assurance in the product's quality and longevity.

By keeping these key points in mind, you can navigate the market and select a booster batterie that not only meets your needs for boosting a car but also serves as a reliable power bank for your other devices. With the right emergency jump starter in your vehicle, you'll have the confidence and capability to handle dead battery situations with ease, minimizing the disruptions and inconveniences they can cause.
