Lithium-ion chargers are smaller, lighter and, consequently, a lot more portable than lead-acid chargers. Lithium-ion is the more advanced battery technology. There are two broad types of portable jump starters, lithium-ion and lead-acid. But if you're unsure why the battery died, have your mechanic look at your car to make sure the battery is being correctly charged - or can retain its charge normally. If it's because you left the lights on all night or otherwise drained the battery in an obvious, known fashion, the car's alternator should be able to restore charge to the battery once you get going. Reverse-polarity protection: Another quality to look for is reverse-polarity protection, which will provide visual and possibly acoustic alerts if you accidentally place the clamps on the wrong terminals - and they won't give the power until you do.ĭead Battery: Make sure you know why your battery drained in the first place. Capacity is actually more helpful if you plan on using the battery for other things, like operating electronics or charging mobile devices. Instead, the number might just be delivered as "peak amps" or "cranking amps," and the company will state how large an engine it should be able to start.īattery capacity: The battery's capacity, measured in mAh, merely reflects how many times it can be used before needing a recharge, not its inherent ability to start the engine in the first place. Keep in mind when considering one that the battery's ability to start a car is dependent upon many factors, including the size of the engine, the state of the vehicle's battery, whether the car's starter is a more recent and therefore more efficient model - and, lastly, the amperage of the jumper battery itself.Ī mperage rating: The amperage rating ranges between 150 to 450 cold-cranking amps (CCA), though that number isn't always available in the product's specifications. With that in mind, we sought out the best portable jump-starters, listed below. Even if it's not your car that goes terminals-up at a freeway rest stop, it's always worth carrying a portable jump starter so you can be the Good Samaritan someday.
