SMAD’s 7.0 cu ft chest freezer is a propane-fed option for places without steady grid power, such as off-grid cabins. It runs on propane or on a 110V outlet, and its absorption cooling system has no compressor. It is the larger of SMAD’s two chest freezers.
No hands-on testing went into this page. It draws on SMAD’s spec table, the 41-page manual, the store FAQ and policy pages, and owner reviews posted on SMAD’s own store, each credited to the brand’s pages.
In short: a large dual-power chest freezer with a coldest rating of 10.4°F. By the manual’s own description, that suits storing food that is already frozen rather than freezing it.
What the 7.0 Cu Ft Freezer Offers
The model number is DSG-200D2U-A. SMAD publishes these figures for it.
- Capacity: 191 liters net, or 6.75 cu ft.
- Dimensions: 40.6 inches wide, 27.6 deep and 32.7 tall.
- Weight: 141.1 lbs.
- Cooling: absorption, with no compressor.
- Fuel and power: propane (LP gas) or a 110V AC outlet.
- Propane draw: 1.98 lbs every 24 hours.
- Rated range: from 10.4°F up to 32°F.
Treat the “7.0” in the name as a marketing size. The spec table puts net capacity at 191 liters, which converts to 6.75 cubic feet. Prices on the store change, so check the current price at SMAD before you decide. You can browse SMAD’s range on its own site, which includes this freezer.
Two ways to run it
The spec table lists propane use at 1.98 lbs per 24 hours, and that figure sets how long a tank lasts. Dividing a tank’s weight by it gives rough runtimes:
- 20 lb cylinder: about 10 days.
- 100 lb tank: about 50 days.
Room temperature and lid openings move the real numbers. On a 110V outlet the freezer runs as an electric unit instead, and a graphic on SMAD’s product page puts that at 5.35 kWh per day, a heavy load for a solar setup.
Quiet running, per SMAD
SMAD’s spec tables rate the cooling as silent at 0 dB, and its FAQ adds a caveat: faint fluid-flow sounds and small expansion noises can occur. Since there is no compressor or fan, nothing cycles on and off overnight, which may matter in a one-room cabin.
Hardware details
Four details come from SMAD’s materials:
- Feet: adjustable, for leveling. The manual says a tilt beyond 3 degrees hurts cooling.
- Basket: a hanging wire basket sits inside.
- Hinge: balanced, holding the lid at 45° or 75°.
- Lock: a key lock on the lid, which SMAD presents as a way to keep children out.
Why 10.4°F Is the Limit
SMAD sells two chest freezers, and their ranges point in opposite directions. The 7.0 cu ft freezer carries a rating of 10.4°F up to 32°F, and a graphic by its control panel carries the same limit, worded “Down to 10.4°F.” The 2.4 cu ft model is the colder one, rated at -4°F up to 6.8°F.
USDA guidance for the best frozen quality is 0°F or colder, so the 7.0 cu ft rating sits above that mark. The manual is explicit about the intended job: the compartment is for storing food that has already been frozen, and it is not designed for prompt freezing.
That settles who it suits. Keeping frozen meat, fish and ice where a standard freezer cannot run is the use case. A flash-freeze of a large harvest, or storage meant to hold peak quality for months, is a poor match for a 10.4°F rating.
What Owners Say on SMAD’s Store
Reviews of this exact model are scarce. SMAD’s store lists a single one, scored 4 stars. Shipping speed earned praise, while the freezer itself caused trouble, and SMAD answered by arranging a pickup and refunding the order. The reviewer rated the customer service highly.
SMAD’s public reply on that page claims hundreds of units sold and says cooling should be fine when the freezer is started following its guidelines. A single review says little about reliability, so this section also draws on the roughly 40 reviews across SMAD’s other propane models. They sit on the brand’s own store, so read them as brand-side evidence, not an independent test. A few points stand out:
- Support: opinions split. Several buyers praised it, but an owner of the 13.4 cu ft fridge described weak cooling and a callback that never came.
- Documentation: two buyers said setup information was missing or wrong until support supplied it.
- Altitude: an owner of the 9.4 cu ft fridge wrote from a cabin in Colorado, 10,000 feet up, that a cup of water froze overnight on the high dial setting.
- Leveling: an owner of the 2.1 cu ft fridge said it worked well only once it was level.
Setup Rules That Affect Cooling
SMAD’s manual ties cooling performance to setup. Its conditions fall into four groups: placement, gas, power and the first two days.
- Placement: keep the cabinet within 3 degrees of level. If it was tipped in transit, stand it upright for 4 hours before starting it.
- Gas: fit a regulator of 28 to 30 mbar and place the tank at least a meter away. On propane, a bedroom is ruled out, and the room needs fresh air plus a CO alarm.
- Power: run on one power source at a time, and connect directly to a grounded outlet, never through an extension cord.
- First two days: let it run empty for a full 24 hours, then fill no more than a third of the space.
The thermostat dial runs from 1 to 4, with 4 coldest, but it shows no actual temperature, so an appliance thermometer inside is a sensible addition. To light the burner on propane, press the pulse igniter while holding the safety valve button down for 10 to 15 seconds.
Plan on routine upkeep, too, per the manual: fins and burner about every 10 days, gas connections monthly with soapy water, and the burner, orifice and flue at least once a year.
SMAD vs Unique Off-Grid
Unique Off-Grid is a useful comparison. Its catalog credits a founding family with starting the company more than 50 years ago, and its freezers sell through large retailers. The UGP-6F has almost the same footprint as the SMAD, so a side-by-side is fair.
| Feature | SMAD | Unique UGP-6F |
| Interior space | 191 liters (6.75 cu ft) | 169 liters (6.0 cu ft) |
| Weight | 141.1 lbs | 165 lbs |
| Dimensions | 40.6 wide, 27.6 deep, 32.7 tall (inches) | 40.5 wide, 29 deep, 33 tall (inches) |
| Propane draw | 1.98 lbs a day | About 1.8 lbs a day |
| Cold rating | 10.4°F up to 32°F | No range given in the material reviewed |
| Warranty | One year on the warranty page; the FAQ adds five years on cooling parts | One year on parts; five years on the cooling coil; no labor coverage |
By the published figures, SMAD’s cabinet is a little shorter and shallower than the Unique, yet it lists roughly 22 more liters of space and weighs about 24 pounds less. Unique rates its propane draw a little lower. Every figure here is the maker’s own rating.
Unique also sells the UGP-6F CM, a variant with an integrated CO alarm and a safety shut-off, a feature that may matter for indoor installs. SMAD lists no built-in alarm and advises a separate detector instead.
Pick SMAD if a lighter cabinet with more interior space matters most and you are happy to supply your own CO alarm. Pick Unique for its longer history, the alarm variant and its availability at large retailers. Compare current prices for both before you choose, and to see SMAD’s side, browse SMAD’s range on its own site.
Warranty, Returns and Shipping
Read SMAD’s warranty material as two pages that disagree. The warranty page grants one limited year, restricted to orders placed on the SMAD USA website and to the original buyer, who needs proof of purchase. The store FAQ mentions five more years for the core cooling parts, which the warranty page never states. Even the clock is unclear: coverage runs from the day of purchase on the warranty page and from the day of receipt in the return policy. Before paying, email SMAD with your model number, ask which terms apply and when they start, and keep the reply with your receipt.
Return costs depend on the reason. If the wrong or a damaged item arrives, SMAD pays the return shipping. For a defect reported inside the 30-day window, SMAD chooses between taking the unit back, repairing it at no charge or sending a replacement. A change of mind is the expensive case: it is accepted only with SMAD’s agreement, and the buyer pays return shipping plus a 20% restocking fee.
Delivery is free in the lower 48 states and unavailable to Alaska, Hawaii, US territories and PO boxes. Orders spend 24 to 48 hours in handling, and transit takes another 3 to 6 business days. Report any shipping damage within a week, which is the manual’s deadline. If you buy anywhere other than SMAD’s own site, make sure the seller is authorized, and ask SMAD whether that purchase is covered.
Common Questions
How cold does this freezer get?
Its coldest rating is 10.4°F, and the range tops out at 32°F. That sits above the 0°F that USDA guidance sets for the best frozen quality, which is why the manual frames the unit as storage for food that is already frozen.
How long does a propane tank last?
SMAD’s 1.98 lbs a day rating works out to about 10 days from a 20 lb cylinder and about 50 from a 100 lb tank. An owner of the 9.4 cu ft fridge on SMAD’s store reported roughly a month from a 40 lb cylinder, so the model and conditions change the result.
Does it have to be level?
Yes. Past a 3-degree tilt the manual says performance suffers, and the adjustable feet are there for that reason. The store FAQ goes further and says an uneven install can stop cooling entirely.
Can solar power run it?
An inverter can feed the AC mode, but SMAD’s graphic puts AC use at 5.35 kWh daily, a large load for a solar setup. Running on propane avoids that demand.
Can it be used indoors on propane?
Only under conditions. The manual rules out bedrooms and sealed spaces, asks for a fresh-air opening of 3 square inches or more, and wants a window or exterior door in the same room. SMAD’s FAQ adds that a CO detector should always be installed.
The Verdict
On paper, this SMAD freezer offers a large cabinet, dual power and a no-compressor design for off-grid cabins. Its limits are just as clear.
Buy it if you want a big propane-fed chest freezer for food that is already frozen, and a coldest setting of 10.4°F is acceptable.
Pass on it if you need true 0°F storage, or you cannot commit to leveling it and ventilating the room. A thin review history, a manual that two reviewers on SMAD’s store found incomplete and warranty cover tied to buying from SMAD directly are further reasons to read the fine print first.
