Best Portable Car Jump Starters: Turn Down For Watt

Top 7 Best Portable Car Jump Starters

Most of us have been there at some point in our life: it’s a cold winter’s morning, you’re rushing out the door thanks to young Johnny needing a last-minute costume change because of that extra bowl of Cocoa Puffs, you twist the car’s ignition key … and come up with a whole fistful of nothing. Nada. The battery is deader than current plotlines of The Walking Dead. Great, just great.

Fear not, because you have a portable car jump starter tucked away in the trunk for such emergencies. If you don’t, you should – these little powerhouses can save your bacon on a stormy morning or simply provide a jolt of juice when none is otherwise available. Offered in all manner of shapes and sizes, we’re here to help you amp your decision making so you’re not shocked when trying to select from the myriad of booster packs available online.

Okay, enough corny puns – here are our picks for the best portable car jump starters.

Sticking with the thought that highly recommended products should be the result of having a bit of skin in the game, this unit is very similar to the one on which your author has splashed his own hard-earned cash. It is a heavy but stout unit that incorporates one important feature - a dedicated on/off switch.

Some jump starters, a few of which are on this list, depend on trace amounts of electricity remaining in the dead battery in order to 'wake up', This renders the device useless when one is trying to revive an ancient Crown Vic for derby car duty. This booster from Schumacher is so designed and better off for it. The 1000 Amp version is fine but do yourself a favor and pop for the 1200 Amp unit.

This is one of the most highly rated jump starters on Amazon and, if it's good enough for nearly 2000 real-world customers, it should be good enough to make it near the top of our list.

Buying a product simply because it bears a popular label isn't always the best idea but it seems to hold a bit of water in this case.

USB ports also pepper the exterior, along with a digital readout for keeping a critical eye on the amount of remaining juice.

Falling back into the category of tried-and-true traditional tools, this booster pack likely looks like the one your grandfather had in the 1980s, complete with an old school voltage display and big ears on which to wrap the jumper cables. This is not a wholly bad thing.

With 425 cranking amps and thick #2 wiring that is actually good enough for welding, this unit is likely to simply scare your battery into starting without even having to connect the leads. That’s an exaggeration, of course, but the master on/off switch lets you know the thing is working while its 68-inch cables allow the flexibility of reaching batteries stuffed into awkward locations by inconsiderate car designers. You can tell I have experience with this.

While it is true that Sears may have gone the way of Studebaker and Enron, some of their house brands have been brought in-house to reputable manufacturers in a bid to capitalize on their name power. This is what’s happened to Craftsman and also, as we see here, DieHard.

Charge or jump start your car’s battery with this rig, featuring intelligent charge technology which sounds like a legal process but actually deploys a microprocessor to avoid overcharging the dead battery. A maintenance mode allows the DieHard to also act as a battery maintainer, handy if you’re tucking a sports car away for the winter months. LED indicators and a couple of non-descript buttons allow users to choose between charging, boosting, and engine starting duties – although it remains unclear as to the difference between the latter two. It also has the ability to test a car’s alternator tester, if you’re into that type of stuff.

We’re unsure why this device bears the surname of a famous F1 driver but it is safe to say there is little to no connection between the two. While this battery pack will certainly get you on your way, its large size and lardbutt weight probably won’t help your lap times around the streets of Monaco.

Designed for semi-permanent placement in a shop or garage, this wheeled unit can be trotted out when needed to be called upon to boost a dead car. You can be sure it will do so with much élan, as its large size allows it to pack an enormous punch in the form of a 200A engine start for immediate gratification. Auto-voltage detection automatically figures out if the machine you’re boosting has a 6 or 12-volt battery to avoid a reducing everything to a veneer of cinder dust. A 12-foot total reach is handy and the 8-gauge output cables will likely stay flexible in cold weather.

Being very specific in stating its maximum capabilities, the makers of this booster pack say it is able to start gasoline engines up to 7.0L in displacement. Those running an oil burner are limited to 5.0L however, making it useless for most HD pickup trucks such as those from the Detroit Three.

Nevertheless, this could get you out of a jam when you need it the most. So-called intelligent protection clamps are said to guard against short-circuiting, plus offer over-temperature and over-charge protection. At just fifty bucks, your credit card won't be overcharged, either.

FAQs:

Aren't they all alike?

It is wise to select a jump starter that features a dedicated on/off master switch instead of one which relies on a faint electrical charge from a nearly-dead battery in order to “wake up.” Experience has taught your author that if a booster pack is needed, the battery in question is likely to flatter than the Prairies with no life left in it whatsoever, rendering a raise-to-wake jump starter completely useless.

Store them properly

Try to keep these units out of frigid temperatures, as finger-numbing cold can reduce its lifespan. Don’t manhandle the cables and alligator clips, either – damaged units can fail to transmit enough power to start a dead car or create enough electrical resistance to produce dangerous levels of heat.

Are they really worth the money?

For the sake of a reasonable cost of entry, a jump starter is cheap insurance against shivering in a parking lot waiting for the tow truck to arrive. In this case, an ounce of prevention is definitely worth a pound of cure.
