There is no such thing as too much battery capacity. When it comes to smartphones and gadgets, the more additional power you can pack for a long day or a short trip the better. That's why we're telling you about this 36% discount on a Limefuel Lite 15,000 mAh Lithium-ion external battery pack. It's down from its regular $55 price on Amazon to $34.99 on StackSocial with free shipping.

Just think about what you could charge with a 15,000 mAh battery. Flagship Android smartphones pack a 3,000 mAh battery on average, so the Limefuel would provide about 5 charges 4 charges (every charger has an efficiency rating that indicates how much juice is lost during the energy transfer process. We've confirmed with Limefuel that the efficiency rating of the Limefuel Lite is 80%). And because this unit has dual-USB ports, with 1A and 2.1A output, you could charge your tablet with it, but also your Bluetooth earphones and speakers, Android Wear watch (with the cradle), MiFi router, and more.

The Limefuel Lite also packs a handy LED flash for those power outages or dark nights, and an LCD screen to show you exactly how much battery you have left and which ports you are using. It measures 5.8 × 2.8 × 0.9 inches and weighs only 12 ounces, making it close to the size of 3 Galaxy S5s stacked on top of each other—not bad!

The deal is available on StackSocial for another 6 days, with free shipping in the continental US. If you still haven't picked up an external battery pack, this might be the perfect time to do so. I know I love my Limefuel Limeade 13,000 mAh battery. I charge it once every couple of weeks, leave it in my gadget drawer, and whenever I'm headed for a hike or an extremely long day, I just pick it up and go. It has been reliably awesome at its job.
