While smartphone batteries have gotten a little bit bigger over the years and power consumption is getting better, with a good amount of use our phones don't always last us as long as we'd like. The day of nuclear fission powered devices that never need charged aren't here yet, but there are plenty of affordable external batteries/chargers on the market that can provide you much needed juice in times away from an outlet.
Sony is looking to get in on the action and offer an attractive looking package in the process. Instead of packing a lot of power in a rather ugly and thick package, Sony has managed to get the size rather thin while also being easy on the eyes. The slim external batteries will offer capacities up to 7,000 mAh which is enough to charge the average smartphone three to four times and then some. They'll only be available in Japan for now, but will likely come to the US at some point.
Anyways, you'll have three different external batteries to choose from. One of those is the CP-F1L which has 3,500 mAh of power. Using an AC adapter, it can be fully charged in four hours, however, through USB, it will take eight hours. That will run around $60 US.
The CP-F2L (pictured at the beginning of this post) is the one with 7,000 mAh of power and has two USB ports so you can kill two birds with one stone. That will run around $90 US which is priced really well considering ZAGG, the maker of the popular ZAGGsparq, charges $99.99 for their 6,000 mAh capacity.
Lastly is the CP-ELVSP which is shaped similar to a USB stick and has 2,000 mAh of power. While not as powerful as its siblings, it'll help you out with a full charge for most smartphones and will cost around $30 US in four different colors.
Until batteries in phones and tablets improve, many of us will have to rely off an external battery to keep the juice flowing. On the flip side, power consumption has got significantly better from the early days of Android. Now if only other manufacturers could take notes from Motorola and what they did with the RAZR MAXX.
