When your car battery dies, the best way to get it started again is with a jumper box. Jumper boxes are portable power sources that can provide enough power to start a car engine. They are a great investment for anyone who drives, as they can save you the time and expense of calling a tow truck. In this article, we will review the best jumper boxes on the market to help you find the one that is right for you.
The first thing to consider when choosing a jumper box is the power output. This is measured in cranking amps (CA) and indicates how much power the box can provide to start a car. The higher the CA, the more powerful the box. For most cars, a jumper box with a CA rating of 400-600 is sufficient. However, if you have a large or diesel engine, you will need a box with a higher CA rating.
Another important factor to consider is the capacity of the jumper box. This is measured in amp-hours (Ah) and indicates how long the box can provide power. A higher Ah rating means that the box can provide power for longer periods of time. For most purposes, a jumper box with an Ah rating of 15-20 is sufficient. However, if you plan on using the box to power other devices, such as a laptop or cell phone, you will need a box with a higher Ah rating.
Best Jumper Box for Maximum Power and Reliability
When it comes to selecting the best jumper box, several key factors should be considered. These include:
- Amperage: This measures the amount of current the box can deliver, with higher amperage resulting in faster engine restarts.
- Cranking time: Refers to how long the box can continuously provide power for starting.
- Peak power: Measures the maximum surge of power the box can deliver, overcoming resistance in cold or weak batteries.
- Portability: Consider the weight and dimensions of the box, especially if it will be used for roadside assistance or transporting.
- Safety features: Look for boxes with built-in protections against over-voltage, short circuits, and reverse polarity to ensure safety during use.
