A portable power bank is a charger that can hold a lot of power and then can be used to energise your electronic devices. You can charge them before you leave from your home and then carry it in your bag. The best thing about a power bank is that it works on an interface (Mini USB) which is a standard for almost every device. So you do not need to carry an additional or extra battery-pack of each of your devices. These can be easily shared, are small enough to carry and are great savious, when you are least expecting it.
