A pen and a phone charger. The two most borrowed items in the entire world, finally united in one ground-breaking device – The Power Pen. On the surface it’s a sleek, brushed-aluminium stylus, but with just a few gestures you can unlock the full power of this mighty pen. Give the tip a quick swivel and a ballpoint pen starts to emerge. Twist off the other end to access the built-in battery with tips for both lightning and microUSB – it’s got your back whether you’re Apple or Android. Pop the cap to reveal the familiar USB connector and you’re ready to start re-charging. It’s truly the only pen you’ll ever need. Just make sure you don’t let your friends and colleagues get wind of its full potential.
