The JUNOJUMPER  V3 is a rugged IP65 design, lightweight external battery that houses an impressive 7,500 mAh battery pack capable of jumping a completely dead car battery in seconds. The multi-functional battery equip with Japanese Seiko IC features an USB 5V 2.1A and 12V outputs allowing it to charge power hungry devices such as smartphones, cameras, tablets and converting DC to AC via 12V cigarette adapter. Users will never again have to worry about being stranded with a dead phone or car battery. 

There are so many competing portable battery packs in all different sizes and styles. What makes the Juno Jumper different? It’s versatility. The Juno Jumper serves as the perfect gift to get yourself your friends, or your loved ones. Not only does it fit everyone’s lifestyle, it shows your concern and care for others’ safety. In any emergency, the Juno Jumper can power up your phone or tablet, jump your car, and can even serve as a flashlight. Its lightweight slim fit makes it convenient and easy to use for any one. Built in smart cables stop users from harming themselves or their vehicles by notifying the user if the cables are connected to the wrong terminals and stopping the flow of electricity.

Despite its small size, the JUNOJUMPER is capable of far more than just charging small devices.  With its sleek form factor of 6.3" x 2.8" x 1", this little device produces a 12 Volt output at a peak of 750 amps. 

For those of us who don’t know the specifics of cars, most automobiles and motorcycles run on 12 Volts, and can sometimes, well, need a little boost. We’ve all experienced or known someone who’s experienced a dead car battery, and it always seems to happen at the worst times, when you’d least expect.

The JUNOJUMPER 3 provides 12 Volts of power and peaks at 750 Amps to ensure that your dead automobile or motorcycle battery can be brought back to life. 750 Amps is enough to jumpstart almost all 4-Cylinder and 6-Cylinder engines as well as possibly enough to jump start more depending on type of model. 

Throw this device in your purse, carry it in your back pocket, store it in your glove compartment – one day, you’ll be thanking yourself. Just two uses of the Juno Jumper pay itself back. It is less expensive than roadside assistance and most large jump starter batteries. Plus the convenience of its size and ability to charge other devices makes a small investment with large returns!

DO NOT attempt jumping vehicles that require more than 750 Amps of power, such as V8 trucks or Diesel trucks, as it may be harmful to the JUNOJUMPER battery.
