Note: Do not try jumping vehicles that require more than 300 amps of power, such as V8 trucks or diesel trucks, as it may be harmful to the JunoJumper and battery
The JunoJumper is a portable battery pack, with enough power to jumpstart most 4- or 6-cylinder cars. 12 volts, 300 amps, all in a pack roughly the size of a cell phone (and it charges those, too).
Here at The Grommet we put JunoJumper to the test. Fortunately, our offices are right next to a body shop. We plugged it into a long-idle vehicle. Fired right up.
And we didn’t need extra cables, because JunoJumper comes with a set. It also comes with an innovative SMARTec cable that indicates when your car is ready to jump. Plus there’s a LED-light to help operate in the dark, if you weren’t lucky enough to kill your battery during daylight.
The JunoJumper includes a USB port as well. Use it to bring your phones and tablets back to life. Obviously, it's up to the task. As for charging the JunoJumper itself? That can be done with a car charger, or via the included micro-USB cord. It’s like a circle of power.
