Whether you have a slim and compact smartphone or a giant phablet, the bottom line is that there is simply not "enough battery life". Your smartphone may last more than 24 hours with normal use, you must do something and your battery will be about to die. That's why portable chargers are so popular and it's the day you buy one if you need an upgrade or you've never thought of buying one before. Amazon offers a large number of popular models at very low prices, but this sale is only valid for one day, on Tuesdays. What are you waiting for !? Also note that some of them also benefit from a 5% discount on the coupons, so that the final prices might even be lower than what you see below.
