Peak Amps refer to the maximum amount of current a jump starter can discharge in a single shot when cranking the engine in the first burst. If the initial burst fails, the subsequent current that the jump starter can produce to crank start the engine is known as cranking current.
Now, at times, the initial burst of the portable device may be enough to jump start your engine. But, if extended cranking is required, it has to be sufficient otherwise your car won’t start. In other words, the cranking current is often the ideal measure of your device’s real capability so make sure you know about it.
First things first, your device should be able to provide protection for short circuit. This usually occurs when jump leads are touched simultaneously that may to serious damage to the unit and even cause an explosion. Fortunate for you, our top 6 picks above are all tested for circuit protection.
In addition, your preferred unit should provide protection against over-current, overload, over-charge, over-voltage and reverse polarity connection.
- Four-cylinder petrol/gas engines – 150A to 200A
- Six-cylinder petrol/gas engines – 200A to 250A.
- Eight-cylinder petrol/gas engines – 250A to 300A
As for diesel engines, they require a relatively higher cranking current than petrol/gas engines of the same size. In fact, diesel engines need more than two times required by their petrol counterparts.
Most devices are super easy to charge. You simply plug one end of the adapter into the wall and the other into the unit and charge it until it says full. The time it takes to fully charge a jump starter depends on the capacity of its battery and how flat the unit is.
How do low temperatures affect portable jump starters?
Temperatures have an enormous effect on the performance of a car battery. In cold climates, a lead-acid battery can lose more than 50% of its cranking output. Although the performance degradation is not as signifant for lithium-ion based jump starters, they also lose a percentage of their cranking current capacity in low temperatures.
If you’re in areas experiencing such climates, it is recommended to buy a portable jump starter with double the amount of cranking current you found in the guidelines above. Try to buy a device with the highest possible peak and cranking current rating depending on your budget.
What Peak Amp should my car jump starter provide for a Sedan?
Typically, the peak Amp you’d need for most Sedans would be at least 300A. For diesel engines, you can essentially double this current rating. In cold temperatures (approximately -5 to 0°C), this figure needs to be doubled again as the performance drops with the decrease in temperature.
Can using a Jump Starter damage my car battery?
Using a jump starter is not necessary healthy to your car battery, but there is not much you can do if you’re stranded in the middle of nowhere. With that said, if you find yourself constantly jump starting your vehicle, then maybe it’s time to replace it with a new battery. Or, at least, use a battery maintainer that will prevent it from losing charge all the time.
