For this week’s giveaway, we’ve teamed up with Mophie to offer MacRumors readers a chance to win a Powerstation XXL that’s equipped with both USB-C and USB-A, so it can be used with a wide range of devices.

The Powerstation XXL, priced at $149.95, features a 19,000 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 Powerstation 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 XXL Powerstation offers 2.4A quick charging capabilities to charge your devices faster.

Size wise, the Mophie Powerstation 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.

We have four USB-C XXL Powerstations to give away to MacRumors readers. To enter to win, use the Rafflecopter widget below and enter an email address.
