Mophie adds the Spacestation, Space Pack for iPad mini and Space pack for iPhone 6/6 Plus to its Space portfolio of iOS device storage-enhancing accessories, together with a revamped Space 2.0 app.

Space products combine external storage with battery cases, with the app handling file transfers between iDevices, PCs and even Android devices via wifi and secure online portal.

The Spacestation is akin to an external HDD, if with the addition of a 6000mAh internal battery and 2.4A of power. It provides 128GB of storage, while USB connectivity allows for use with PCs, Androids (4.4+) and Macs as well as iDevices.

Apple refreshes the Beats Solo2 Wireless headphone lineup with 3 new colours-- gold, silver and space gray, perfect for customers wanting to match their headphones with their iPhones, iPads or MacBooks.

The Solo2 headphones connect with iDevices via Bluetooth (with up to 9m range) and carry a rechargeable battery the company says powers up to 12 hours of continuous use. Built-in "b" and volume buttons handle phone call, song skipping and volume controls.

Stanford University researchers makes unexpected use of a familiar material with a high-performance aluminium battery said to be a faster-charging, longer-lasting and safer alternative for powering mobile devices.

"We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames," chemistry professor Hongjie Dai says. "Our new battery won't catch fire, even if you drill through it."

In theory aluminium makes an ideal battery material, as has low flammability and a high-charge storage capacity while being low cost. However, in the past researchers have failed to find a materials capable of producing sufficient voltage after repeated charge-discharge cycles-- a problem the Stanford scientists solved by using graphite, the carbon-based wonder material.

Many wearables sell themselves on the basis of being able to handle multiple tasks, from fitness tracking to applications and notifications. However the Emvio is different, as its only task is stress management.

According to makers Data Systems chronic stress is caused by repeated daily annoyances, not occasional life-changing events. The Emvio promises to help by constantly measuring heart rate to determine the wearer's emotional state (but "it's not as simple as "excited = more beats per minute" and "calm = fewer beats per minute,"", the company insists). Should stress levels get too high, the wearable vibrates and provides tips on how one can calm down.

Once the wearer is sufficiently calm the Emvio, perhaps ironically, vibrates again to let the know exactly that.
