Battery life can be an issue for anyone. It doesn't matter if you device is an older one or even one of the latest flagship devices. They all consume too much power and far too quickly. As such the power bank market has been on an upward trend recently. Power banks are becoming far more available but also starting to become far pricier. At least for the big power and branded items. Well, if you are in the market for a power bank, then you might want to take a quick look at the RAVPower Deluxe Portable Charger. This is an 8,400mAh capacity battery, comes with dual USB ports and is currently at the very low price of $12.99. Which makes it a bargain for a branded and high powered unit such as this. Not to mention, you have the choice of both black and white colors too. If you are interested you can grab yours by clicking the link below.
