ChargeWrite -:

The creators of this pen call it the “world’s coolest pen.” Let’s find out why. The ChargeWrite comes with a built-in 16GB flash drive and powerbank. That’s right, this pen works both as storage and charger. ChargeWrite also makes use of a universal smartphone tip, i.e, it works with both lightning ports and microUSB ports. Of course, it’s not called a pen for nothing. When not in use as a powerbank or storage unit, ChargeWrite can still be used a ballpoint pen; and they’re giving free replacements for all their Indiegogo backers. But that’s not all, you can use the ChargeWrite as a stylus as well. To charge the ChargeWrite, you can pull off the top half of the pen to reveal a USB plug. ChargeWrite can hold up to 1000 mAh of charge. Look for ChargeWrite on Indiegogo if you’re interested in getting one yourself.
