Running out of power when you need it the most is annoying. But that’s something you can prepare for by getting a portable charger aka power bank. Since you’ll be presumably bringing it around a lot, it’s best to go for one that’s sleek and light without compromising capacity. An option to consider is the U-Stone 12000 mAh portable charger, an award-winning power bank that meets all of the above (it was a Red Dot Design Winner back in 2013.)
It’s compatible with all smartphones and tablets that use a 5 volt charger. The best part? It’s currently on sale at 65% off, bringing down the price to $34.99 for a limited time only.
