Harness the power of the '90s with two external batteries modeled after a Tamagotchi and an old brick cell phone. Created by Wattzup and sold on Firebox, both 2600 mAh batteries can charge your phone up to one and a half times its normal capacity. The batteries work with most phones and include a micro-USB port.

The brick phone comes in pink and gray, while the Tamagotchi comes in pink with a static, smiling digital pet on the screen. While you can't make calls or feed pets using these external batteries, you can at least charge your phone in style. Get the phone or Tamagotchi on Firebox.
