How to choose the best portable jump starter
Many of these top-rated portable jump starters share many common features and this can be confusing to a buyer. Here is what you should look out for when buying your portable jump starter.
This measures the jump starter’s level of power output. So, the larger your engine, the more amperes needed to jumpstart it. The peak amperage is the maximum power output your jump starter can generate.
However, what you should be on the lookout for is the cranking amp rating which is the real indicator of how much power the jump starter can generate every 30 seconds while maintaining the minimum volts on a 12V battery. To get the right ampere range for your car’s jump starter, check your owner’s manual or your battery specifications.
Different types of jump starters have different features and specifications. Pocket-size jump starters trade off some features for their compact sizes. On the flip side, the heavier units have more power, are multifunctional, and have useful extra features like an air compressor. Choose according to your requirements.
Features and functionality
The best car battery jump starters will cost you quite a bit so it’s a good idea to get in as much functionality as you can. Naturally, the more premium jump starter brands cost more, but they are well worth it if these extra functionalities are useful to you.
Some things to look out for include electrical safety protections, LED flashlight, LCD battery status display screen, air compressor feature, USB charging ports, and 12V outlets.
Cable length and gauge
Whether you want short or long cables is a matter of personal choice, but the recommended length is 12ft. You want enough manoeuvrability to use the jump starters while keeping safe.
The gauge of the wires in the cables also determines how fast the power is transmitted to your battery. Look out for a 6-gauge cable-anything above 8 gauge is too thin.
Many cars have 12v batteries while some larger autos, like trailers and trucks, have 24 volts. Simply match your emergency battery booster pack’s voltage to your vehicle’s battery voltage.
