If you were planning to equip your car with a jump starter so you will no more have problems restarting your car when it has battery related problems, you might want to read this article.  We will present here a comparison of all the NOCO Boost jump starters which were the most popular and best rated jump starters bought by Amazon customers.

Jump starters are portable compact battery devices used for restarting vehicles when the vehicles's battery is not doing the job. The way they work is similar to jumper cables, but no other vehicle is required to provide the power needed to boost the  vehicle's battery.

Jump starters come in various sizes rated in Amps. Traditional jump starters use lead-acid batteries which can be extremely large and heavy, making them less than convenient to carry along. In addition, lead-acid batteries may self-discharge due to a condition known as "sulfating", which permanently reduces battery capacity. This can completely destroy a brand new lead-acid battery within months, requiring a replacement.

Fortunately, jump starters equipped with lithium-ion batteries are now available. Lithium-ion jump starters are extremely compact and lightweight, much smaller than lead-acid equivalents. They also have a much longer lifetime than lead-acid batteries. The NOCO Boost jump starters that will be presented and compared below are all equipped with lithium-ion batteries.

At the time of this writing, the NOCO Boost jump starters available on Amazon were:

• NOCO Boost SPORT GB20 400 Amp​
• NOCO Boost PLUS GB40 1000 Amp​
• NOCO Boost XL GB50 1500 Amp​
• NOCO Boost HD GB70 2000 Amp​
• NOCO Boost PRO GB150 4000 Amp

​Note that the above listed NOCO Boost jump starters had all received an average rating of 4.5 stars (out of 5 stars) and great reviews from Amazon customers who have bought and used them.
