Coleman Power Supply Adapter for Thermoelectric Coolers — 120V to 12V DC, 5A Output, Compact

Coleman's power supply adapter lets you run compatible thermoelectric and Stirling coolers from a standard 120V household outlet by converting AC to 12V DC.

When you want the cooling convenience of a Coleman thermoelectric cooler away from your vehicle—at home, in an office, a dorm room, or a cabin—this compact power adapter gives you that flexibility. Designed to accept a standard 120‑volt plug and output a regulated 12‑volt DC connection at up to 5 amps, it converts portable coolers that normally draw power from a car’s cigarette lighter so they can operate from wall outlets. The adapter is lightweight and simple to use: plug it in, attach your cooler’s 12V plug, and start cooling without reworking cords or batteries.

Which Coleman coolers work with this adapter?

This power supply is compatible with Coleman 12‑volt thermoelectric and Stirling coolers. To confirm a match, check the model number on the cooler's base; the adapter supports many common models and general 12V TE/ST cooler connections.

• Works with Coleman TE and Stirling 12V coolers, including models like 5232, 5274, 5640–5645, 5726, and 6216.
• Fits any cooler that uses a standard 12V car‑style barrel plug and requires up to 5 amps.
• If your cooler lists a different model, verify the bottom‑plate model number before purchase.

How do I use the adapter safely at home or in a workspace?

Operation is straightforward and requires no tools. Insert the adapter into a grounded 120V outlet, then plug your cooler's 12V cord into the adapter's output; avoid using damaged cords or ungrounded extension setups.

• Input: standard 120V AC household outlet; output: 12V DC, rated at 5 Amps.
