Jackery's New Lightning Cable Has a Battery Built Right In, and You Can Score a Launch Discount

Jackery makes some of the most popular battery packs around, but the brand new Jackery Jewel is unlike anything we’ve ever seen.

Really, the Jewel isn’t so much a battery pack as it is a Lightning cable with a battery bulge in the middle. That 450mAh battery is only good for a ~15-20% charge, depending on the iPhone model, but that can be the difference between finishing the night with a working smartphone or an inert slab of glass.

When it’s plugged into a charger or computer, the Jewel also acts as a standard Lightning cable, except that while it’s refueling your phone or syncing data, it’s also recharging its built-in battery. Jackery sent me one of these to try out a few weeks ago, and I often find myself using it around the house when I want to stave off battery anxiety without tethering myself to a power outlet.

For a limited time, Jackery’s offering a 20% launch discount on the Jewel with promo code JERJEWEL, so if you want to add this to your charging gear collection, there’s no reason to wait.
