RAVPower USB-C Power Delivery Battery Pack | $54 | Amazon | Promo code KINPB058

There are only a handful of USB battery packs out there with USB-C Power Delivery, and this is one of the best prices we’ve ever seen on one of them.

$54 gets you RAVPower’s 26,800mAh battery pack, complete with a 30W USB-C port that can power a MacBook or Nintendo Switch at basically full speed, plus two regular USB ports as well. That should be enough power to get you through pretty much any long flight.
