Griffin Reserve power bank - 2 x USB - 17 Watt

Engineered with a smooth, packable form, this Power Bank easily fits into your on-the-go lifestyle, whether it's being slipped into your bag, backpack or luggage. With 10,000 mAh, you can give your smartphone, wearable or tablet the 100% power boost it needs before (or when) it hits 0% - perfect for a weekend away. In fact, the 12W USB-A outputs power that's more than 2x faster than most standard wall chargers that come in-box with your device. And the additional 5W USB-A port lets you conveniently charge two devices at the same time. When the Power Bank itself runs low on juice, you can effortlessly recharge it using the included micro-USB cable. Plus, the built-in LED power gauge shows the battery's charge capacity with just a quick push of the power button.
