Powerful as it is, the jumper box has a compact design and only weighs 7.5 pounds. It has a waterproof (IP65-rated) rubberized over-molded housing that will ensure safe use in any climate and will protect the device from scratching and damage during transportation.

Modern jump starters can be portable enough to fit in a glove compartment and yet powerful enough to start cars, boats, trucks, vans, and SUVs. The Imazing IM27 is one of such devices.

An ergonomic display on the unit's front panel shows the battery charge percentage and that attached to the cables displays the voltage (the data is updated every 5 seconds) and an error code if an error occurs. The only downside we have found is that the included booklet is not comprehensive enough.

Not all jump starters are powerful enough to boost a big car's battery. If you have a usual passenger car, there would probably be no problem to boost it with almost any jump starter available. However, if you drive a large vehicle requiring plenty of power, you'd need to use something like the Clore Automotive JNC660, a jump starter housing in a huge amount of power and being capable of boosting even several cars.

Among all jump starters on this list, the JNC660 is also the largest one measuring 16.3 x 14.1 x 5.1 inches. This, as well as a powerful motor, makes it the best choice for professional use in car service centers. Featuring DC 12 V voltage, the JNC660 provides 1700 peak Amps and 425 cranking Amps - plenty enough to move off all types of cars, including those fitted with gasoline-powered engines.

The Clore Automotive JNC660 is a fantastic option not only for boosting a car battery but also for charging other gadgets such as smartphones, laptops, tablets, or any other device with a USB port. However, note that in order to use it for that purpose, it is necessary to buy a special charging device, which you can buy either from the internet or your local store.

Quality jump-starters can revive your car's battery in seconds, but most of them take too long to recharge after use. What makes the HULKMAN Alpha85 stand out from the crowd is a patented 65W Speed Charger that allows you to fully recharge the unit in less than 1.5 hours. If compared to 4.5-5 hours that you would need when using a conventional 18W charger, the results are truly impressive. Moreover, even if the device is 20% charged, you can still use it to start your car. What is also stunning, when not in use, the jump starter will hold its charge for up to 18 months.

This model has a 20,000mAh battery, and it can be used for up to 60 jump-starts on a single charge.

To prevent misoperation, the jump starter uses as many as nine types of protection. Along with a 2-year warranty, the manufacturer provides lifetime technical support, which is also a pleasant bonus.
