While stock lasts, you can pick up a 2,100mAh Universal Battery Pack for $7.89 (61% off). As reflected in the price, this accessory doesn't feature any bells and whistles like an integrated microUSB, so you'll need to carry around your own. It's still a great purchase, though.
If you like the sound of the 2,100mAh Universal Battery Pack and want to take advantage of this promotion, hit the Buy Now button below. We advise you to hurry, though, as Amazon only has a very limited amount of inventory available for this specific deal.
