Best Portable Jump Starters for Every Driver
There are few worse feelings than turning the key and hearing nothing but a click — usually in a parking lot, usually when you’re already running late. A portable jump starter fixes that without needing a second car or a good Samaritan with cables. Modern lithium units are small enough to live in a glovebox or door pocket, yet powerful enough to crank a dead engine back to life in seconds.
The catch is matching the unit to your vehicle. Jump starters are rated in amps, and a 500A pack that’s perfect for a motorcycle won’t reliably turn over a big diesel pickup. Engine size and fuel type matter, and so do the extras — many packs double as USB power banks, flashlights, and even air compressors, which turns a simple safety device into a small roadside kit.
Below are jump starters that are popular and well-reviewed, with a heavy showing from NOCO — a brand enthusiasts repeatedly recommend — plus a few capable alternatives. We’ve arranged them roughly by capability so you can find the right amount of power for what you drive. These aren’t units we’ve personally tested; picks reflect reputation and customer feedback.

Buying Guide: Choosing a Portable Jump Starter
Match amps to your engine. This is the most important decision. Smaller gas engines and powersports are happy with 500–1000A; most everyday cars and SUVs do well around 1000–1500A; large trucks and diesels want 2000A or more. When in doubt, size up slightly rather than down.
Lithium vs. lead-acid. Nearly all modern portable units are lithium, which means they’re compact, hold a charge for months, and weigh a fraction of old lead-acid boosters. Just remember to top them up a couple of times a year so they’re ready when you need them.
Safety features matter. Look for spark-proof connections and reverse-polarity protection — they prevent the dramatic sparks and damage that can happen when clamps touch the wrong terminal. This is an area where established brands like NOCO have a strong reputation.
Extras worth having: a built-in air compressor (great for road trips), USB-C in/out for fast recharging, a bright work light, and a power bank for devices. Don’t pay for capability you’ll never use, though.
Common mistakes: buying an underpowered unit for a big engine, letting the pack sit dead for a year, and assuming every unit can handle diesels. Read the engine-size rating, not just the peak-amp headline number.
Frequently Asked Questions
How many amps do I need to jump-start my car?
Most everyday gas cars and SUVs are well served by 1000–1500 peak amps. Smaller engines can get by with less, while large trucks and diesels typically want 2000A or more. Check the unit’s stated engine-size rating to be sure.
Can a portable jump starter start a diesel?
Many can, but you need to match the rating. Smaller units are gas-only, while higher-output models like the NOCO GB70 and GB150 are designed for larger diesels. Always confirm the diesel displacement the unit supports.
How often should I recharge it?
Lithium jump starters hold their charge well, but it’s smart to top them up every few months so they’re ready in an emergency. Many units show their charge level on a display or indicator lights.
Are these safe to use if I’m not a mechanic?
Yes. Modern units with spark-proof clamps and reverse-polarity protection are designed to be beginner-friendly and forgiving of mistakes. Still, follow the instructions and connect the clamps in the right order.
What’s the benefit of a built-in air compressor?
It lets one device both restart a dead battery and reinflate a low tire, which is genuinely useful on road trips. The trade-off is added bulk and slower inflation on larger tires.
Can I use it as a power bank?
Most modern jump starters double as USB power banks for phones and other devices, and many include a built-in flashlight. It’s part of what makes them handy to keep in the car year-round.
How long do these last?
A quality lithium unit can last for years with proper care, including periodic recharging and storage out of extreme heat. The battery will gradually lose capacity over time like any lithium cell.
