Advertising electric cooler with personalization

The customized electric cooler is a rigid insulated equipment with an integrated thermal regulation module, designed to keep food or drinks cold or hot using a thermoelectric system that operates on a 12V socket (cigarette lighter) or 230V (mains), with an integrated transformer or external adapter depending on the models. The body is made of double-walled molded polypropylene or polycarbonate, injected with high-density polyurethane foam (PU), with an insulating thickness of 20 to 40 mm ensuring prolonged thermal retention even after power is cut off. The capacity usually ranges from 20 to 35 liters, with standard dimensions around 40 × 30 × 40 cm and an empty weight of 3.5 to 6.5 kg depending on the capacity and integrated components. The lid is hinged or clipped, sometimes with a peripheral soft seal to optimize air tightness. The Peltier unit is located in the lid or one of the sides, with a low-voltage internal fan and an aluminum heat sink. The cooling temperature averages -15 to -18 °C compared to the ambient temperature, with some versions offering a warming function up to +60 °C. Advertising marking is done on the front face, flat lid, or sides, by direct UV printing or screen printing, with an exploitable area of 100 × 80 mm to 200 × 150 mm depending on the geometry. It should never be placed on ventilated areas, nor on the motor's heating parts. The interior is smooth, without sharp angles, with a one-piece injected container for easy cleaning with a damp sponge, without slots or textile joints. The 12V cable measures between 1.8 m and 2.5 m, with a standard cigarette lighter plug; some versions include a cable storage compartment in the lid. The 12V/230V models have a manual selector or automatic voltage detection, with protection against polarity reversals and overvoltages. The electric consumption averages from 45 to 70 W, with continuous ventilation during power supply, and passive thermal inertia once unplugged. The side handles are molded in mass or clipped, with a resistance tested at a minimum of 20 kg in continuous traction. The quality test includes the ability to maintain thermal retention for 4 to 6 hours (under full load), fan noise (<45 dB at 1 m), and interior temperature stability. The packaging is done in reinforced individual cardboard, with stabilizing wedges, multilingual instructions, and mandatory CE / RoHS / WEEE marking. A poor product quickly shows signs of weakness: poorly closing lid, excessive fan noise, thermal instability, or poorly placed printing. A good electric cooler remains stable, quiet, efficient, easy to maintain, and features visible, clear customization, resistant to abrasion and perfectly adapted to the rigid surface of the body.
