Sometimes while out at a Starbucks jotting some notes down about your upcoming novel you plan on thinking about writing in the near future, you're phone may run low on batteries. Luckily this super-secret battery pen is here to save your day. Aptly named the Ballpoint Pen Power Ring, the pen is able to be unscrewed in the middle to reveal a micro-USB or Apple Lightning plug so you can plug the pen right into your phone to charge it up.
