One for fun, the other for work? If that's how you roll with your iPads, then you might be well trained in the art of battery juggling. If, however, you're not, or you just like to keep things tip-top at all times, then makers of fine accessories, Sanho, have the product for you. The company claims the HyperJuice Plug is the world's first 15,600 mAh portable battery pack that can recharge a brace of iPads at the same time -- complete with retractable wall plug for convenience. It's not just Apple's slates, of course, with pretty much all USB gadgets being able to mainline the 15 watts (sharable over two ports) of juice. The HyperJuice Plug launched this week at the Singapore PC show, and lands in six "juicy" colors, yours from an equally juiced up $129.
