A short circuit could potentially cause the device’s battery to explode or, at a minimum, damage the jump starter. One of the most important features to look out for is short-circuit protection. Try to get a jump starter that has safety features that protect you and the device itself. It goes without saying that safety is a top priority when dealing with high-voltage batteries. What to look out for here are user reports that highlight a jump starter’s battery not holding a charge while it’s still relatively new. However, some low-quality batteries will have short lives. How you treat your battery and the temperatures you use it in will largely determine how long it lasts. Battery Qualityīatteries degrade over time there’s no getting around it.
So, if you don’t want the hassle of keeping the starter topped up or need to jump-start vehicles frequently, you should get one with a large battery. Generally speaking, the larger the battery, the more times it can jump-start an engine on a single charge.
Some starters will have larger batteries than others. Portable jump starters like the ones on our list are powered by a rechargeable battery.
