USB-Powered Thermostatic Cup Heating Pad

Physical specs: 9 cm × 9 cm × 0.7 cm. Power: 5V/2A (10W max). Materials: medical-grade silica gel outer layer, 0.5 mm thick aluminium heating plate, copper traces, and durable PVC-insulated USB cable (70 cm). Designed around sustained thermal comfort: avoids abrupt temperature spikes or drops by continuously adjusting power draw within safe limits. Aluminium’s high thermal conductivity ensures minimal lag between activation and effective warming, while its even dispersion prevents localised hot zones that could damage cup glazes or warp thin plastic bases. Silicone shell is soft yet resilient, offering tactile feedback and slip resistance — especially valuable on polished desks or laminate tables. Universal USB interface allows direct connection to devices commonly found in UK households and workplaces: Windows/macOS laptops, Anker/RavPower power banks, car dash sockets and IKEA-style USB wall chargers. Intended for regular use with hot beverages — compatible with standard UK mug sizes (250–400 ml), including popular brands like Le Creuset, Bodum and Ember-compatible vessels (base-only contact). Not intended for use with vacuum flasks or tapered-bottom containers.
