Your phone powers it. You just press the button. That's genuinely all there is to it.

1

Plug into your phone's USB-C port

ThermaBite draws a tiny amount of power from your phone — about 0.1% of your battery per treatment. No pairing, no app launch. It's just ready.

2

Press the button once

The ceramic tip heats to precisely 51°C in under 2 seconds. Hold it on the bite. The built-in timer handles the rest — no decisions needed.

3

Feel the relief — itch gone in 20s

ThermaBite beeps and auto-shuts off at 20 seconds. The concentrated heat neutralises the itch response at the source. Back on your keyring, job done.

Your phone is the battery.
That's the point.
No AA batteries to replace. No charging cable to forget. ThermaBite is always ready — as long as your phone has charge.
