A portable jump starter earns its keep the moment your battery dies in a parking lot or driveway and you don't have another car around to jump you. The right one depends on how big your engine is, how much extra capability you want built in, and how much you're willing to spend for a bigger safety margin.
For this guide, we looked at four jump starters built for different needs and budgets, and made sure no two solve the same problem for the same buyer. The GOOLOO GP4000 is the best value pick for anyone who wants strong peak amperage at a low price. The NOCO Boost GB40 is the best overall pick, the single best-selling jump starter on Amazon with a review base far deeper than any other pick here. The GOOLOO A5 is the pick for anyone who wants a genuine 2-in-1 tool that jump starts your car and airs up your tires. And the NOCO Boost HD GB70 is the premium pick for anyone with a bigger engine who wants double the peak amperage and more margin for cold starts.
We compared these jump starters based on peak amperage, engine size supported, extra features, and price, and made a point of not picking four jump starters aimed at the same buyer. On raw value, the GOOLOO GP4000 wins outright, at under $80 with 8,901 ratings and 2K+ bought in the past month, at the cost of a lower peak amperage than the NOCO picks. The NOCO Boost GB40 is the single most trusted pick here by a wide margin, the #1 Best Seller in its category with over 128,000 ratings and 30K+ bought in the past month, at just under $100. The GOOLOO A5 breaks from the standard jump starter design entirely, adding a built-in 160 PSI tire inflator, at essentially the same price as the GB40 despite solving a second problem entirely. The NOCO Boost HD GB70 is the outlier of the group: double the peak amperage of the GB40 at 2000A, rated for larger gas and diesel engines, at exactly double the GB40's price.
Quick Notes
The GOOLOO GP4000 is our Best Value pick because it delivers strong 4000A peak amperage at the lowest price in this lineup, backed by 8,901 ratings and 2K+ bought in the past month. The buyer here is someone who wants a dependable jump starter for a standard car or SUV without paying for the extra brand premium of the NOCO picks. One concrete detail that matters is the SuperSafe lithium battery design with spark-proof clamps, engineered to prevent the sparking and reverse-polarity mistakes that make jump starting intimidating for a lot of drivers. A second detail is the built-in LED work light, giving you visibility for connecting clamps in a dark parking lot or driveway, which is a genuinely useful addition at this price point. The tradeoff is that it doesn't carry the extensive track record of the NOCO Boost GB40, which has more than ten times the ratings of this pick. Skip this one if you want the single most proven, most reviewed jump starter available. Buy it if you want strong peak amperage at the lowest price here.
Quick Notes
The NOCO Boost GB40 is our Best Overall pick because it's the single best-selling jump starter in this lineup and on Amazon overall, backed by over 128,000 ratings and 30K+ bought in the past month. The buyer here is someone who wants the most trusted, most widely proven jump starter available for a standard car, truck, or SUV. One concrete detail that matters is the UltraSafe spark-proof technology with reverse polarity protection, engineered to prevent the two most common jump-starting mistakes, which is a big part of why it's become the most trusted name in the category. A second detail is the compact, lightweight design that fits easily in a glovebox or trunk, meaning it's genuinely there when you need it rather than left at home because it's too bulky to carry. The tradeoff is that at 1000A peak amperage it's rated for smaller engines than the GOOLOO or NOCO HD picks, meaning larger trucks or diesel engines are better served by the GB70. Skip this one if you drive a larger vehicle or diesel engine and need more amperage. Buy it if you want the most trusted, best-selling jump starter available.
Quick Notes
The GOOLOO A5 is our pick for 2-in-1 convenience because it's the only jump starter in this lineup with a built-in 160 PSI air compressor, at essentially the same price as the standard NOCO Boost GB40. The buyer here is someone who wants a single tool that handles both a dead battery and a low tire instead of carrying two separate devices. One concrete detail that matters is the auto-off tire inflator with a digital pressure display, engineered to stop automatically at your target PSI, which takes the guesswork out of airing up a tire on the side of the road. A second detail is the 4000A peak amperage paired with a built-in LED flashlight, giving you the same jump-starting capability as the GOOLOO GP4000 plus visibility for nighttime roadside stops. The tradeoff is that combining two tools into one means a bulkier unit than the standalone NOCO Boost GB40, and its review base is thinner at 712 ratings. Skip this one if you already carry a separate tire inflator and don't need the extra bulk. Buy it if you want one tool that jump starts your car and airs up your tires.
Quick Notes
The NOCO Boost HD GB70 is our Premium pick because it's the only jump starter in this lineup built for larger vehicles, doubling the peak amperage of the standard GB40 at 2000A, backed by over 30,000 ratings and 7K+ bought in the past month. The buyer here is someone who drives a bigger truck, SUV, or diesel vehicle and wants more amperage margin in reserve, especially for cold-weather starts. One concrete detail that matters is the engine rating of up to 8.0L gas and 6.0L diesel, engineered to reliably start larger engines that would push a smaller jump starter like the GB40 to its limit. A second detail is the same UltraSafe spark-proof and reverse-polarity protection as the GB40, so you get the extra power of the HD line without giving up any of the safety features that made the standard NOCO pick so trusted. The tradeoff is price and size: at $199.95, it costs exactly double the GB40, and its larger battery pack and cables make it bulkier to store than the more compact picks here. Skip this one if you drive a standard car and don't need the extra amperage. Buy it if you drive a larger vehicle and want more power margin in reserve.
