Speaker that charges your smartphone

Speakers for listening some groovy music is fine but a speaker that can charge your gadgets like smartphone or iPad is something that would make your ears perk up.

Los Angeles-based Outdoor Tech has designed "smart" speakers named "Big Turtle Shell" that charge other devices' batteries while you listen to music.

When the speaker is laid flat, it can still push sound in directions other than straight up in the air.

Not only does the "Big Turtle Shell" offer impressive battery life -- its powerful battery gives you up to 16 hours of playtime per charge, it also charges other devices for you.

There is a USB port built into the side of it.

The speaker can charge smartphones as well as iPads and other devices that require 2.1-amp charging.

That makes it a useful multi-purpose tool for camping, beach trips, and other outdoor adventures.

According to a wired.com report, the "Big Turtle Shell" is shock proof, sand- and dust-proof and water-resistant.

The speaker supports Bluetooth 4.0, NFC pairing, and line-in input through a 3.5mm port, the report added.
