The powerstation USB-C XXL, priced at $149.95, features a 19,500 mAh battery, which Mophie says is enough juice to provide USB-C laptops (the MacBook specifically) with up to 14 hours of additional battery life.
Because it has both a USB-C and a USB-A port, the USB-C XXL can be used to charge all of your Apple devices, from the MacBook to the iPhone and iPad. The USB-C port offers up to 30W of charging, so it can fast charge your iPhone X, iPhone 8, or iPhone 8 Plus when combined with a USB-C to Lightning cable.
With fast charging, an iPhone X, iPhone 8, or iPhone 8 Plus can charge to 50% within 30 minutes, so that's a super handy feature to have available from a portable battery back. At 30W, this charger will work with the 13 and 15-inch MacBook Pro models, but the charging will go more slowly and you won't see much gain while the machines are in use.
Over a standard USB-A to Lightning or micro-USB, the powerstation USB-C XXL offers 2.4A quick charging capabilities to charge your devices faster.
Size wise, the powerstation USB-C XXL is heftier than your average iPhone battery pack, but it's still portable at 6 inches long, 3 inches wide, and an inch tall, plus it looks quite nice with its fabric-wrapped body.
