Portable batteries are great for juicing up your gadgets when away from a power outlet. The problem is, most battery powered chargers deliver electrons at a snail's pace. Fortunately, thanks to Qualcomm Quick Charge 2.0 technology, there's a new crop of batteries that are both portable and fast. One of the better ones is Aukey's 10,400mAh battery, and right now you can pick one up for $20, a third less than the normal price.
Besides QC 2.0 technology, there isn't a lot to be said about the battery. It has one USB port, four LED charge level indicators, and a nice rounded aluminium shell. It's well rated and should perform its function admirably. If you want to grab one, enter the code 9N8DQWM9 at checkout to apply the $10 discount.
