Tesla makes the Powerbank compact portable power bank, which is small, lightweight and packs plenty of power to keep your devices charged while on the road. The Powerbank comes with a 3350mAh capacity battery, which delivers 5V/1.5A.
The charger has two built in cables: a USB cord for recharging and a Lightning cable for all of your Apple devices. It also comes with a detachable micro USB cable for other devices. A nice touch is the charge status indicator so you know when it’s ready.
The device is out of stock at the moment, but Tesla says it will be available online in February for $45.
