Our digital devices have a habit of dying on us when we need them most, and power outlets aren’t always easy to come by. That’s why it’s always a good idea to carry a portable battery pack like the Limefuel Lite, which carries enough juice to power multiple devices for a whole weekend. Thanks to Cult of Android Deals, it’s just $34.99.

Carrying a micro USB cable isn’t always enough to keep your devices running all day long. If you find yourself without access to mains power, that cable might as well have stayed at home. But you don’t need mains power if you have an external battery pack. Whether you’re camping in the middle of a field, sunbathing on a beach, or hiking through the forest, it will keep all of your mobile devices charged up.

The Limefuel Lite is perfect for those who need to charge multiple devices on-the-go, or frequently find themselves away from a power outlet for several days at a time. It has a massive 15,000mAh capacity, which is enough to charge larger devices — such as a tablet — 2-3 times, and smaller devices even more than that.

Because the Limefuel Lite uses a standard USB connector, it’s compatible with almost every mobile device. It’s also incredibly portable, measuring just 5.8 x 2.8 x 0.9 inches, and weighing only 12 ounces. Throw it into your pocket, purse, or backpack and you’ll hardly even notice it — until one of your devices runs out of battery and it comes to the rescue.

The Limefuel Lite uses Grade A battery cells and high-quality circuitry to provide protection against short circuit, anti-discharge protection, anti-overcurrent protection and anti-explosion protections. It also promises over 500 use cycles, with auto-on and auto-off for preserving power.
