The Best Cheap Jump Starters (Under $100) For Sale on Amazon in 2018

A portable jump starter is a blessing if your vehicle's battery goes dead.

Being stranded in bad weather (or a bad neighborhood) is a stressful situation, even if you have a roadside assistance plan. A jump box is a way to get your own vehicle running.

Jump boxes are small enough to fit in a trunk. A basic portable jump starter is just a rechargeable battery with cables and clamps attached. Some all-in-one kits include an air compressor and various charging ports, but the heart of any jump starter is a battery.

Remember to recharge that battery if you want the jumper to work (i.e. you can't keep a jump starter in your trunk for years and expect it to keep a charge). Recharging your jump box each time the seasons change — winter, spring, summer fall — is a simple way to remember.

Here are the best-reviewed portable jump starters selling for less than $100 on Amazon. Not all jump starters pack enough power for every vehicle, so use Amazon's "Shop by vehicle" tool before buying.

Buyer Beware

Amazon sells dozens of well-reviewed jump starters, but I wouldn’t buy many of them. Here's why:

  1. Most jump kits can also charge phones or laptops. As a result, there are thousands of positive reviews left by customers who never used their jump box in an emergency. I was shocked to see how many 4+ star products failed to successfully jump a vehicle in a time of need. Failure is disguised as success.

  2. I wouldn't buy a jumper that isn't UL-listed. Batteries can explode (remember hoverboards), and many direct-from-China products don't have the safety certifications that we take for granted.

The $200 Antigravity XP-10-HD jump start kit uses UL-listed battery cells, has near perfect Amazon reviews and is recommended by Consumer Reports. The extra expense may be worth it.
