Jumpstart my car, truck, and boat, a flashlight can last for a week, charge my phone 7+ times, and battery standby for a year.


The JUNOJUMPER V3 is a sleek, 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 equips with Japanese Seiko IC features a USB 5V 2.1A output allowing it to charge power-hungry devices such as smartphones, cameras, and tablets. Users will never again have to worry about being stranded with a dead phone or car battery. 


We're used to carrying a bulky jumper pack that sells in your local automobile hardware store, where it packs a flashlight, two jumper cables, and weighs... well, 25 lbs or so.  It's not easy to carry around, and we usually throw it in the trunk. The newly designed JUNOJUMPER V3 is roughly 0.73 lb making it extremely lightweight and portable.


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, but it also shows your concern and care for others’ safety. In an emergency, the JUNOJUMPER  V3 can power up your phone or tablet, jump your car, and can even serve as a flashlight. Its lightweight design makes it convenient and easy to use for anyone. 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.


The JUNOJUMPER V3 is capable of far more than just charging small devices.  With its rigid and durable design factor of 6.3" x 3.1" x 1.1", this device produces a 12 Volt output at a peak of 10 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 know someone who’s experienced a dead car battery, and it always seems to happen at the worst times, when you’d least expect.


Remove the unit after starting your vehicle.  Do not jump start anything that's not recommended.
