It’s taken a long time, but Belkin has finally released the first Apple-approved battery pack that features a Lightning port input for charging. In other words, instead of recharging your battery pack with a MicroUSB or USB-C cable, you can plug it in to the same Lightning cable you use for your iPhone or iPad, as spotted by MacRumors.

Aside from the Lightning input, the rest of the BoostCharge Power Bank Lightning 10K is pretty standard by battery pack standards. There are two USB Type-A ports for plugging in your cable of choice for recharging your gear on the go: one a faster, 2.4 amp jack, and the other a slower 1 amp plug. The battery itself is a 10,000mAh cell, which should be enough to recharge an iPhone a few times over (presumably you’re using the Lightning-equipped accessory with one of Apple’s phones, although it will work with anything you can plug into the USB ports).
