Amazon Top 4 Jump Starters to Buy in 2025

If you’re looking for high performance packed with useful features in a sleek design, the HULKMAN Alpha85S is our top recommendation. “During testing, this model produced the highest voltage of any jump starter in our review,” noted our lead tester. “Its battery lasted significantly longer than others, and it was also the fastest to recharge.”

We love its intuitive design—a large digital display shows the exact battery percentage, eliminating the guesswork of traditional LED meters. The built-in flashlight is bright and practical, and its compact shape easily fits under a seat or in a door panel. The Alpha85S is also versatile, with multiple charging options. It can be powered via USB or a 12-volt car outlet and can also charge USB and 12-volt devices, making it a powerhouse for both jump-starting and charging on the go.

If a high-capacity portable power bank is your top priority and jump-starting is an occasional need, the GOOLOO GP2000 stands out with its impressive 37Wh lithium-ion battery and versatile charging options. Delivering up to 2000 peak amps, it performed well on mid-size vehicles, successfully completing eight consecutive jumps on a 2.5-liter engine before requiring a recharge. However, it lacked the power to handle larger truck batteries.

Where this model truly excels is in its ability to charge electronic devices. In our tests, it fully recharged an iPhone up to 15 times using its 5V USB port, and its USB-C input/output adds extra convenience. Though it isn’t the most powerful jump starter for larger engines, its long battery life, compact design, and excellent accessory-charging capabilities make it a great value for those who need reliable portable power.

If you’re short on space or prefer a compact jump starter, the NOCO Boost Plus GB40 is an excellent choice. “This tiny powerhouse outperforms its size,” says one of our testers, “successfully starting every vehicle we’ve tested.” Unlike many models that require a waiting period, the GB40’s ‘Boost Mode’ delivers an instant power surge, often allowing immediate starts. It also boasts an IP65 waterproof rating, making it resistant to dust and light rain. “You won’t want to submerge it, but a little water won’t hurt,” another tester noted.

However, the GB40’s versatility is limited. It can jump-start a car and charge USB devices, but that’s about it. Charging is only possible via USB, and it doesn’t include a wall adapter. At 1000 peak amps, it’s not the best option for larger engines. “Its small size means a shorter battery life,” our lead tester pointed out, “so regular recharging is essential.” Despite these drawbacks, the NOCO GB40 delivers strong performance in a highly portable package. If you’re willing to invest more, the Hulkman Alpha85S offers a more powerful battery and additional accessories, making it a top contender in the portable jump starter category.

For a versatile home shop power station, the Dewalt DXAEJ14 goes beyond just jump-starting dead batteries. “Need to air up your tires? Check your alternator? Charge your phone?” noted our lead tester, highlighting its multifunctionality. The 120 PSI air compressor, complete with an LCD screen for precise PSI settings, adds convenience. Delivering 1400 peak amps, it can jump larger engines while also powering devices through dual USB ports and a 12V DC outlet. While bulkier than lithium-ion models, it offers superior engine-boosting power with enough reserve for additional tasks.

Unlike lithium-ion alternatives that provide multiple jumps per charge, the DXAEJ14 requires recharging after every use. Additionally, its sealed lead-acid battery needs regular maintenance—Dewalt recommends topping it off monthly. However, with a 21Ah battery, it surpasses similar SLA models in power capacity. “That performance, plus its versatility (and hefty 35-pound weight), makes it a shop favorite,” said one tester. For a budget-friendly SLA alternative, the Stanley J5C09 offers similar features, including a USB port and 120 PSI compressor, while maintaining solid battery performance at a lower cost.
