Questions people ask
Can I pair two speakers?
Yes. The brand lists True Wireless Stereo (TWS) support for pairing two Supernova speakers.
How long does the battery last?
The brand states 9 hours on a single charge. One reviewer measured around 7 hours at 60% volume, so playtime depends on volume and lighting.
Can I use it while it charges?
Yes. The brand says USB-C charging supports mid-use recharging.
Is a wall charger included?
No. The box has a USB-C charging cable, and a review notes a power brick is not included.
Can I connect it with a cable?
Yes. It has a 3.5mm AUX input, and a 3.5mm auxiliary audio cable ships in the box.
Does the surface it sits on matter?
It can. A reviewer notes the sound comes out of the bottom, so the surface affects the sound.
