What is jumper starter?

A battery jump starter also knows as a battery booster, is a device used to jump start your car when your car battery is dead or low on voltage. A portable jump starter is primarily a lithium ion power bank  enclosed in a safe and secure box that cranks up your engine by generating a powerful current in a short period of time.

Extreme weather deteriorates a vehicle's battery, thus it is a good idea to remain a battery jump starter  with you, especially in places that experience harsh cold weather conditions. Our jumper starter has a wide range of vehicles,like cars, trucks and jeeps. Each battery jump starter is manufactured with  superior safety features such as reverse charging protection, polarity protection, shorcircuit protection  and much more. Battery boosters are highly portable and compact devices, and they can easily fit in the gloves compartment of your car. So, next time you are stranded on the road, you can get your automobile running with our battery jump starter.
