Made for wherever lunch happens
From steaming hot to ice cold
Triple thermoelectric core
Three solid-state Peltier modules sit on copper heat-spreaders. Reverse the current and the very same cores switch from heating to cooling — no compressor, no coils, no moving refrigerant.
Active airflow & power cells
A row of brushless fans pulls heat off the sinks for fast, even temperature changes, while the high-density cell stack feeds the system. Three pogo contacts dock the detachable battery.
The brain & the ports
A custom control board runs temperature logic, Bluetooth and multi-layer safety cutoffs, driving the front status display. USB-A and dual USB-C sit on the front edge for charging in and power out.

Up to 14 hours of heating or 12 hours of cooling per charge, and it recharges 0–100% in about 30 minutes. Swap in a spare module for more.
All food-contact parts are food-grade and dishwasher-safe — just remove the battery module first. The body is splash-resistant.
We will email every reserver the moment production and shipping dates are confirmed, so you are always the first to know.
