Try to make it through the day without your phone: it’s nearly impossible. We can’t imagine hitting up concerts, cons, or even school without having something on hand to give our phones a little juice when the battery dips too low.

But a plain, colored charger is no fun. These MimoPower portable chargers are the geeky solution that give your phone some much-needed juice — in style. From Mimoco, these adorable portable chargers charge your phone to 100% and are designed like your favorite video games and geeky characters. Designs include a retro Nintendo NES controller, the Legend of Zelda logo, and the Super Mario Bros. game.

The power banks are available in a variety of themes — including characters from movies, comic books, pop culture, and video games — and sizes. And with just one look, my trusty black charger has been cast aside for these colorful, fun, and geeky versions. (And yes, they actually function well.) Plug your cable into the device, connect to your phone, and watch the battery charge.

The MimoPowerDeck, which can fit in your hand, is the manufacturer’s largest portable battery and has an 8000mAh capacity that will charge smartphones, tablets, and 5V devices on the go. The company also makes the MimoPowerTube2, which is decorated like your favorite characters in a compact, slender tube shape that fits easily into a backpack, purse, or pocket. Mimoco also has a universal MimoPowerBot that can charge any device on the port of its sculptural character design.

Each charger includes a power button, two USB outputs, pass-through charging, and four LED lights that indicate how much battery your charger has. It’s easy to use, simple to carry around, and good-looking. Charging your phone has never been more convenient, fun, or geeky than it is with these portable devices. Charge up!

Ranging from $19.99-$39.99, these portable chargers are affordable, too.
