Kegerator Power Supply: AC Compressor vs DC Thermoelectric

What AC and DC mean on a kegerator listing

AC and DC are power supply words, not cooling-performance words. AC (alternating current) is the standard current from a wall outlet. DC (direct current) is a low-voltage current supplied through an adapter. On kegerator listings, AC usually appears on compressor-driven units, and DC usually appears on thermoelectric units.

These words show up in the title, the bullet list, or a small line near the plug type. A listing that says AC compressor has told you the power type and the cooling type at once. A listing that says thermoelectric has told you the cooling type without always spelling out DC. The site compares stated details on listings; it adds no performance claims of its own.

When you need to decide which type suits your space, start by reading the first few words of the title. A title that begins with kegerator, keg refrigerator, or keg dispenser usually goes on to name the taps and any defining words. AC, DC, compressor, and thermoelectric are all words you may meet there.

Compressor-driven kegerators

A compressor-driven kegerator uses a sealed compressor and refrigerant. This is the power type behind most full-size, undercounter and commercial kegerator listings, and it is the usual type when a title does not name another one.

When you see compressor, AC, full size, commercial or direct draw together in a title, you are reading a compressor listing. For multi-tap and wide cabinets, this is the common type. Compare those listings on stated details with the Best Kegerator and Best Commercial Kegerators guides.

Compressor-driven units often appear in the same size lines as standard refrigerators. That means you can look for the same cabinet width and tap count that you would expect from a regular home appliance listing. The phrase AC compressor tells you the power type, but the listing still needs to state the width, the number of taps, and what is included in the box.

• Words that tell you a compressor listing: compressor, AC, full size, commercial, direct draw.
• Multi-tap and wide kegerators are usually compressor-driven.
• A compressor listing may still leave out the cabinet width, so read the dimensions in the bullet list.

Thermoelectric kegerators

A thermoelectric kegerator uses a solid-state heat pump; it has no compressor. It commonly runs on DC from an adapter, so the listing may state DC or DC power, or just thermoelectric. You will see this word mostly on compact, portable and countertop kegerators, and on some single-tap models.

Thermoelectric listings tend to match small spaces: an apartment, a home bar with one beer, or a tabletop setup. If you want a single tap and a small cabinet, the single-tap guide is a good place to compare what is stated.

Because the word thermoelectric appears on compact units, you should check whether the listing states that the unit is freestanding or built-in. A compact thermoelectric unit may be made for countertop use, while a slightly larger one may be meant for undercounter placement. Read the box contents and the dimensions before you compare.

Reading power type in a title and bullets

Power type can appear in the first words of a title, in the bullet list, or only in the model code. Makers often encode the type in the model line, so read the code on the listing before you decide.

If a listing says only kegerator or keg dispenser, the seller has not stated the power type. That is one of the details this site marks as not stated by the seller. A title cannot tell you everything; Kegerator Thermoelectric vs Compressor explains the wording in more depth.

When a listing shows a model code that contains letters such as DC or TE, those letters may be part of the maker's naming system. Some codes use AC to identify the AC-powered version of a line. The listing text should still say what the code means; if it does not, ask the seller before you buy.

Which power type fits home use

For home use, the choice starts with taps, then space. A single-tap compact unit may be thermoelectric; a dual-tap home bar unit is usually compressor. An undercounter kitchen unit is usually compressor too.

Read the stated width, taps and box contents of each listing. The undercounter guide compares those size lines on stated details.

If you are placing the kegerator in a garage or a shared house, the power type alone will not tell you whether the unit fits. The cabinet width, the number of taps, and whether the listing says it is a full-size or compact unit are the details that matter. A compressor listing with a 24-inch width may need more floor space than a thermoelectric countertop unit.

For a second kegerator, you might already know the kind of space you have. Compare the stated height and depth as well as the width. The guides include those numbers when they are stated on the listing.

Which power type fits commercial use

For a small venue or shared space, commercial is the title word to look for. Commercial kegerator listings are compressor-driven, and their titles often add direct draw, stainless steel, multi door and casters.

The commercial guide and the wide commercial guide compare those listings on stated details, including taps, width and included parts. A commercial listing may state the cabinet width in inches, the number of doors, and whether it comes with casters. The power supply is almost always AC because the unit uses a compressor.

When you read a commercial listing, check whether the box includes a tower or whether the taps are mounted on the door. Some commercial units are sold as cabinet only, without the dispense parts. The listing text will usually include a note that says not stated by the seller if that information is missing.

What a listing can still leave out

What the site can tell you is what a listing states: power type, taps, width, included components, warranty words. What the site cannot tell you is how a unit performs in your room, how it handles gas, how to install it, or what local rules apply. Those are not in the listings.

Read the box contents list, check the warranty wording, and ask the seller about anything a listing does not state. The full-size guide is a useful starting point.

The power supply type is only one line in a listing. The same maker may offer an AC compressor line and a DC thermoelectric line under different model numbers. The site's maker guides, such as Best Kegco Kegerators, show how those lines appear in the catalogue.

What to pick for your situation

Questions

What does AC mean on a kegerator listing?

AC (alternating current) is the standard current from a wall outlet. Most compressor-driven kegerators use AC.

What does DC mean on a kegerator listing?

DC (direct current) is a low-voltage power supplied through an adapter. Thermoelectric kegerators commonly run on DC.

Is a thermoelectric kegerator the same as a compressor kegerator?

No. Thermoelectric uses a solid-state heat pump; compressor uses a sealed compressor and refrigerant. The listing usually states which one.

If a listing does not say AC or DC, what should I do?

Read the title and bullet list for compressor, thermoelectric, or the model code. If none appears, ask the seller or read the manual link.

Which power type is used on commercial kegerators?

Commercial kegerator listings are compressor-driven; commercial, direct draw and stainless steel appear in their titles.

Can the site tell me if one type cools better?

No. The site compares stated details only; it does not publish performance claims about cooling.

Does a thermoelectric unit always say DC in the title?

Not always. Some listings say only thermoelectric, while others include DC power. Read the bullets for the power supply line.
