Iceman by Chefman Pebble Ice Maker (RJ56-PB18-SS and RJ56-PB-V2)

What Chefman publishes

Both machines, side by side, from the Specifications blocks on Chefman's own product pages. The thing to notice is how few blanks there are.

For context on how unusual that is: the Kismile nugget machine has no specifications section in its manual at all, the Euhomy publishes nothing we could source, and the AGLUCKY, VEVOR and Cowsar bodies publish a wattage without a voltage. Chefman gives you both, plus a model number printed on the page rather than hidden in an image filename.

The first-ice claim that runs backwards

Here is the oddity. Chefman claims the larger, higher-wattage machine makes nugget ice in 20 minutes, and claims the cheaper, lower-wattage Compact starts making restaurant-style nugget ice in 8 minutes.

The practical reading: treat both numbers as marketing until someone times them, and do not choose between these two machines on first-ice speed. Choose on bin capacity and on shape, which are the two figures here that are unambiguous. Why first-ice claims in this category are generally unreliable is the argument on how long a nugget ice maker takes.

The shape difference is the real decision

These two machines are not a big one and a small one. They are the same machine in two different shapes, and which one fits depends on what your constraint is.

Standard kitchen wall cabinets sit about 18 inches above the counter. The 15.35-inch RJ56-PB18-SS is tight under one and needs the lid clearance to fill it; the 8.9-inch Compact slides under comfortably. But the Compact pays for that with counter area, so if your problem is a shortage of worktop rather than headroom, the taller machine is actually the smaller intrusion. The same trade is worked through on nugget ice makers for small kitchens.

2.4 pounds is a genuine middle

Bin capacity is the figure that actually constrains a countertop machine, because the bin is not refrigerated and the machine stops when it is full. The category clusters at two values: 3.0 lbs across the Opal family, and 1.5 lbs across the shared budget OEM body that turns up badged as a VEVOR, a Cowsar and an AGLUCKY.

The RJ56-PB18-SS's 2.4 lbs sits between them, and it is published rather than inferred. That is roughly five tall glasses against the budget bodies' three — a real difference in how often you stand waiting for the machine. The Compact, at 1.5 lbs, is back on the budget figure. Why the bin and not the daily rating is the number to shop on is set out on how much ice you actually need.

What they cost to run

Both machines publish a wattage with a voltage, which is all a running cost needs. At four running hours a day and the US residential average of 18 cents a kWh:

The 65-cent monthly gap between them is not a reason to choose either. For the whole category in context, including why four hours is the assumption and what changes if you leave the machine running, see what a nugget ice maker costs to run and whether to leave it on all the time.

What Chefman does not publish

• No current rating. 170 W and 120 V are given, but no amperage. A wattage is enough for a running cost and not enough for a nameplate, so there is no documented figure to size a shared circuit from. That matters in a dorm or an office, and it is covered on electrical requirements.
• No operating temperature range. Six machines on this site publish one. Neither Iceman does, so there is no manufacturer guidance for a hot garage or an unheated porch. See what temperature an ice maker needs.
• No refrigerant type or charge, which is the one figure that tends to appear even on thin spec tables.
• No noise figure. Only one machine on this site publishes one at all, with heavy caveats, and it is the VEVOR.
• No bin or reservoir figure in a manual. Everything here comes from a product page. Product pages change without a revision number; manuals do not. These values were read on 17 October 2026 and are stamped accordingly.

Who each one is for

• Buy the RJ56-PB18-SS if you want the best-documented nugget machine under $250 and the 2.4 lb bin, and you have 15.5 inches of vertical clearance plus room to open the lid.
• Buy the RJ56-PB-V2 Compact if the machine has to live under a wall cabinet. 8.9 inches is the lowest published height on this site, and no other machine here solves that problem on a published figure.
• Skip both if you need a published current rating or a documented operating range. The original GE Opal and the Frigidaire Gallery EFIC255 publish those in a manual.
• Skip both if you want the biggest bin you can buy. That is the GoveeLife Smart Nugget Ice Maker Pro at 3.5 lbs, for more money.
