Listen to this articleMost of us keep a charging cable (or two) in our bags or in our car, and many of us keep an extended battery pack in our bags. Sometimes it’s a bit much to carry that extra battery, but if you carry the Jackery Jewel lightning Power Cable, you’ll have a two-in-one power solution.
The Jackery Jewel functions as a very useful 39.4″ sync and charge cable; the cable itself is rubber-coated and tangle-free. Closer to the Lightning end of the cable, there’s an approximately 4″ long torpedo shaped addition to the cord; it’s a 450mAh battery pack built into the cable!
450mAh is enough to give your iPhone 3S an additional 3 hours of battery life; the cable is MFI certified, so you should never see the dreaded “this accessory is not compatible … ” warning that sometimes pops up when you’re using a non-MFI certified accessory (so aggravating). On the front, there is a power button that when pressed starts the battery pack when it is attached to your phone.
The Jackery Jewel cable has an included velcro wrapper that’s handy when storing the cord.
When you have the Jackery Jewel plugged into a USB port, it is not necessary to press the button for it to sync or charge your device, but when that extra 450mAh is needed, it’s just a button push away. I like that normal use of the cable keeps the battery topped off, and being able to bring it along means you are also bringing along a mini battery pack; it’s the best of both worlds.
The Jackery Jewel Lightning Cable retails for $19.99, and it is available from Amazon [affiliate link]
