Built for a classroom
Your phone stays your phone.
Audio arrives over Bluetooth rather than a cable, and the input stage is protected, so nothing you connect gets fed high voltage back. The sound is cleaner than a standard arc plasma speaker too.

Questions
Before you buy.
Read this first
The arc is high-temperature plasma and will ignite paper, fabric, solvents and anything else flammable. Run it on a clear surface, keep it away from pacemakers, phones, cards and hard drives, and never leave it running unattended.
Is it safe to have on a desk?
Yes, on a clear hard surface with nothing flammable nearby. The output is high frequency, so it feels different to mains voltage, but treat it as a piece of lab equipment rather than a toy and keep it out of reach of young children.
Will it damage my phone?
No. Audio arrives over Bluetooth, so your phone is never wired to the coil, and the input stage is protected.
What music sounds best?
Square-wave tracks. Ordinary music plays, but it is thinner. Search for square wave or chiptune versions and the difference is obvious.
Does it work on UK mains?
Yes. The adapter takes 110-240V at 50/60Hz. EDIT: confirm whether you ship a UK plug.
How long can I run it?
In short bursts of a few minutes, with breaks. The finned base sheds heat, but continuous running shortens component life.
What if it arrives faulty?
EDIT: your returns process. Twelve-month warranty and 30-day returns is standard for this category.
