Gravastar lives outside the box with its speaker designs, and the company’s latest products don’t stray from that mold.

The new Gravastar Supernova is a sci-fi-inspired Bluetooth speaker, unlike any speaker you’ve seen before. And it’s not just a speaker; it’s also a lamp.

The Supernova typically sells at a cool $60, but a current back-to-school promotion knocks 20% off the usual sticker price. That’s insanely good. Pair that with the Alpha65 fast charger, and you got yourself a nice little package there.

Gravastar Supernova offers a mesmerizing visual experience

The Supernova is a unique Bluetooth speaker that stands apart from any competition. It has alien claw-like feet and a glossy metallic build that resembles some alien spacecraft.

On the top of the speaker is an ambient light with three different lighting modes. There’s dynamic lighting, single-color lighting with eight different options, and Camping light mode to imitate the flickering of a campfire.

The speaker itself provides 25W of sound for an impressive volume in a small package. It has a Bluetooth 5.3 connection, or you can go wired with an AUX cable.

Each battery charge gives you up to seven hours of playback. Plus, there’s a plastic handle on the top for carrying, making it a great option for camping or hiking trips.
