A portable jump starter is a battery pack that starts your car when the battery is dead, without needing another vehicle or cables to a second car. The difference between a great jump starter and a frustrating one comes down to its starting power for your engine, its safety features like reverse-polarity and spark protection, and its build quality and extra functions. The picks below earned their tiers on real starting power, safety, build and value.
The most important factor in a jump starter is whether it has enough power to start your engine, which depends on your engine size and fuel type, since a small four-cylinder car needs far less cranking power than a large V8 or diesel truck. Look at the peak amps and the manufacturer’s stated engine ratings, and choose a compact unit like the NOCO Boost for most cars or a higher-amp unit like the GOOLOO for big gas and diesel engines, leaving some headroom for cold weather, which reduces starting power. Safety is the next critical factor, since connecting jumper clamps wrong can spark or damage electronics, so look for reverse-polarity protection and spark-proof clamps, which the best units have, making them safe for anyone to use. After that, consider the build quality and capacity, where a larger battery both cranks bigger engines and lasts longer as a power bank, and the extra functions many units include, such as USB charging for phones, a bright LED work light and emergency flash modes, and on some models a built-in air compressor like the Stanley for inflating tires. Finally, weigh the size and weight for storing it in your trunk, and remember to recharge it periodically so it is ready when you need it.

The NOCO Boost is the best for most people, a compact, safe lithium booster that starts most cars and doubles as a power bank. The GOOLOO is the best high-power value for big engines, and the AVAPOW is the best overall value.
Match the peak amps to your engine. A compact unit like the NOCO Boost starts most four and six-cylinder cars, while large V8 and diesel engines need a higher-amp unit like the GOOLOO. Leave headroom for cold weather, which reduces both your car battery and the starter performance.
Quality jump starters with reverse-polarity protection and spark-proof clamps, like the NOCO Boost, are safe and forgiving even if you connect them slightly wrong. Always follow the instructions, attach to the correct terminals, and keep the unit charged so it is ready and performs safely when you need it.
Match the starter to your engine, since a small four-cylinder needs far less cranking power than a big V8 or diesel. Check peak amps and the stated engine ratings, choosing a compact unit like the NOCO Boost for most cars or a higher-amp unit like the GOOLOO for big engines. Leave headroom for cold weather, which cuts starting power.
Connecting clamps wrong can spark or damage electronics, so safety is critical. Look for reverse-polarity protection and spark-proof clamps, which the best units like the NOCO Boost include, making them safe for anyone to use even in the dark or in a hurry. These protections are worth prioritising over a slightly lower price.
A larger battery cranks bigger engines and lasts longer as a power bank. Consider extra functions like USB charging for phones, a bright LED work light, emergency flash modes, and on some models a built-in air compressor for tires. Factor in size and weight for trunk storage, and recharge the unit periodically so it is ready when needed.
