Product identity
The Unique-Bargains TEC1-12710 is a 12V thermoelectric cooler rated at 120W maximum cooling power. It suits hobbyists and engineers building custom cooling or heating modules for electronics, automotive accessories or experimental setups. The 40mm square ceramic package measures 3.4mm thick and includes a 29cm power lead. Polarity reversal switches the device between cooling and heating modes.
Capacity and headroom
At 12V the module draws up to 10A and moves 120W of heat when the hot side is held at ambient temperature. The temperature differential across the junctions can reach 58°C with no load, while the operating range spans -55°C to 83°C. Internal resistance sits between 1.2 and 1.5 ohms. Without an adequately sized heat sink on the hot surface the cooler will overheat and fail rapidly.
Critical specification
The single figure that decides fitment is the 120W Qcmax rating at 12V. If the thermal load you must move exceeds this value, or if your power supply cannot deliver 10A continuously, the module will not maintain the desired temperature difference. Buyers needing higher heat-pumping capacity or lower current draw must select a different Peltier device.

Questions about this item
Will the 12 V 10 A Peltier module work with my existing 12 V power supply and heat sink?
Yes, it runs on 12 V and draws up to 10 A; pair it with a heat sink rated for at least 120 W on the hot side.
How do I confirm the cooler is operating correctly after wiring it?
With red to positive and black to negative the marked face should drop below ambient within minutes; reversing polarity makes that face heat up.
Does the package include thermal paste, a heat sink or a longer power cable?
Only the 40×40×3.4 mm module with a 29 cm lead is supplied; thermal compound and a heat sink must be purchased separately.
