The Supernova is GravaStar’s latest sci-fi Bluetooth speaker and doubles as a lantern


GravaStar has pretty funky designs in a world of “normal” looking Bluetooth speakers and true wireless earbuds. We’ve reviewed a few in the past and the company’s latest sci-fi-inspired Bluetooth speaker doubles as a lamp. In addition, the company has also released a mecha robot-inspired GaN charging adapter.

GravaStar’s speaker designs aren’t for everyone, but they are pretty cool if you’re into sci-fi and robotic looks. While offering up pretty decent sound, the company is adding some pretty major light effects to its newest addition: the Supernova.

“GravaStar wants to bring an explosive sound experience to every aspect of life. Supernova is built to be taken anywhere: the office, home or even camping. It lights a path forward while bringing the soundtrack to any adventure.” 

Yong Huang, GravaStar founder and industrial designer

The Supernova has a solid zinc alloy metallic body perched on top of GravaStar’s signature tripod leg design, a key feature in both the Mars and smaller Venus Bluetooth speaker designs. The latest Bluetooth speaker has 25 watts of power and 90db output with a 3″ full-range speaker and 0.5″ high-frequency tweeter. What sets it apart, however, is its clear tubed center which displays a number of different light effects that allow it to double as a lamp while indoors or out.

A first for GravaStar, the company is branching out from audio products. Their first non-audio device is a GaN-based charging adapter, reminiscent of robots from classic sci-fi films. The Alpha65 features collapsable legs, allowing you to display it in a standing position on your desk while not plugged in, and sitting while plugged into a wall outlet or power bar.

“GravaStar strives to take products that are traditionally ‘boring’ and transform them into nostalgic, collectible items that also incorporate the latest technology available. Alpha65 safely and quickly powers devices while doubling as a mini mecha robot.” 

Yong Huang

As far as functionality is concerned, Alpha65 has two USB-C and one USB-A port, all with intelligent detection. By utilizing GaN technology, this cute little charging adapter delivers up to 65W of power and has overvoltage, overcurrent, short circuit, and over-temperature protection. In addition, the classic robot shell design is flame-retardant.
