It’s amazing what can be fit into small packages these days. The micro SD memory card in my GoPro camera measures 1cm x 1.5cm and isn’t much thicker than a business card, yet it has a 16GB capacity. Even more remarkable, micro SD cards are available up to 128GB!

The JunoJumpr has LED lights to indicate charge level, a built-in LED flashlight and a USB port for recharging electronic devices.

Batteries have gotten smaller, too. Ultra-light and compact lithium batteries are available for many motorcycles. And then there are devices like the JunoJumpr, which is a lightweight, powerful lithium polymer battery pack with enough juice to jump start a dead motorcycle or car (up to 6 cylinders) and still be able to recharge your smartphone. It weighs just 7.4 ounces, is rated at 6,000 mAh (milliampere-hour) and, at 12V, cranks out 300 amps of peak power.

Measuring 5.5 x 3 x 0.6 inches, the JunoJumpr battery pack is somewhat larger than my iPhone 5 (see photo above). The $99.99 kit also comes with a set of Smart jumper cables, and, for recharging the battery pack, a car charger and micro USB cable. The standard USB port is rated at 5V / 2.1A, ideal for recharging smartphones, cameras, some tablets and other devices. The JunoJumpr has a built-in LED flashlight as well as four blue LEDs to indicate the level of charge.

The JunoJumpr lithium battery back fits is small enough to pack just about anywhre.

With the JunoJumpr fully charged, I jump started two different motorcycles with completely dead batteries, and afterward all four blue LEDs were still illuminated, indicating a nearly full charge. When I plugged in my dead iPhone 5, it immediately dropped to three LEDs (75 percent), and then to two LEDs (50 percent) after fully charging the phone. After a second full iPhone recharge, only one LED was illuminated (25 percent). I attempted a third iPhone recharge, but it only got up to 16 percent recharged before the JunoJumpr ran out of juice.

I use the JunoJumpr to recharge my iPhone and GoPro when on the road, and it provides peace of mind should I find myself with a dead motorcycle battery. That alone is worth the $99.99 price. And it’s small enough to pack into a saddlebag or backpack so I carry it with me all the time. No claims are made about being waterproof or shockproof, so I recommend keeping the battery pack sealed in a plastic bag and storing it and the jumper cables in a padded, zippered pouch.
