![]() Prior to becoming a journalist, I also worked in a garage, where our responsibilities often included testing batteries and jump starting dead ones. In that time, I’ve tested a variety of vehicles and automotive products, including jump starters. How We Selectedįor the past five years, I’ve worked as an automotive journalist. ![]() Along with faster charging, a 12-volt rail expands the range of devices that you’ll be able to power. Most jump starters provide a number of USB ports, but the real kicker is to look for a 12-volt outlet. Outside of their main function, battery jump starters can also recharge phones, tablets, and other portable tech, so pay attention to interface ports. However, this is most relevant when starting your vehicle, as anything above 1,000 amps would fry your mobile device in an instant. ![]() More amperage generally leads to faster charge times and the ability to start bigger engines-as long as your vehicle can handle it. This measures how much electricity the battery can supply in a given moment. Peak AmperageĪlong with capacity, peak amperage is another important metric to look out for. We recommend looking for jump starters that have at least 10,000 mAh of capacity, though you can get one that's nearly double that size, like our best overall pick. Although some manufacturers measure battery capacity in terms of how many vehicles or devices it can charge, the standard unit of measure is milliampere hours (mAh). Battery Capacityīattery capacity is important because larger packs re-fire a greater number of vehicles and devices before they need to be recharged-bigger numbers equate to more capacity. These devices, sometimes called battery jump starters, are essentially heavy-duty backup batteries equipped with jumper cables, so take into account metrics like capacity, amperage, and interface ports. Thankfully, portable jump starters are quite simple to compare to one another.

If the car battery is old won't hold a charge, a jump kickstarts the engine so you can drive to an auto store for a replacement. While this can happen in any season, winter is especially tough on your car and extreme temperatures can cause the battery to fail to supply enough amps to the starter motor.Ī portable jump starter is a lifesaver to get you where you need to go quickly and safely if there isn’t another driver around to give you a boost - or if you don't want to engage with a stranger while stranded.
