Portable power whenever and wherever you need it. With this travel-friendly, 4,000mAh Reserve Power Bank, you’ll get the essential battery recharge for your smartphone, smart watch or tablet when it’s running on low—while you’re on the move.
Power Wherever You Are— Engineered with a smooth, small form, this Power Bank easily fits into your on-the-go lifestyle, whether it’s being slipped into your bag or packed in your backpack or luggage. With 4,000mAh, you can give your smartphone, wearable or tablet the 100% power boost it needs before (or when) it hits 0%—perfect for a full day out.

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.
