Because so many smartphones have sealed batteries, we can’t easily change them out when they get low and we need our devices to keep operating.
Sony has one solution - new, slim battery pack accessories designed to power either your smartphone or tablet.
The CP-F5 and CP-F10L, 5,000mAh and 10,000mAh are sleek and stylish, and pretty run-of-the-mill as far as battery packs are concerned. They will charge your device in less than two hours, and take about 7 hours to replenish using AC power. The CP-F5 will have one port, while the CP-F10L will have two for charging multiple devices.
But currently they're only available in India, at Sony stores and other major electronics retailers. The CP-F5 will run about $42, while the CP-F10L will set you back around $72.Source article
