Our take
The Commercial Chef CHM770W is the documented white version of a compact 0.7-cu.-ft. countertop microwave. Its maker lists 700 W of microwave output, ten power levels, six preset menus, time and weight defrost, and short one-touch express cooking. The manual adds 120 V/60 Hz electrical requirements and counter clearances. It may suit a buyer looking for a plainly specified small white unit, but the cited sources do not establish sensor cooking, trim-kit compatibility, or turntable diameter, and they disagree on body dimensions and weight.
A compact white household microwave with straightforward preset and manual controls.
Look elsewhere if you need a larger cavity, a high documented output, a verified turntable diameter, sensor cooking, or confirmed cabinet-kit installation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Commercial Chef explicitly identifies CHM770W as the white finish and separates it from black CHM770B and stainless CHM770SS family codes.
- The model page gives a useful control inventory: ten power levels, six presets, time and weight defrost, a timer, clock, and express cook.
- The manual distinguishes 700 W microwave output from 1,100 W power consumption and states 120 V/60 Hz electrical requirements.
What to weigh up
- At 0.7 cu. ft. and 700 W, it is a compact, lower-output choice beside larger models in this comparison.
- The product page and manual give conflicting exterior measurements and weights, so the exact space requirement is unresolved here.
- The reviewed documents do not establish sensor cooking, a compatible trim kit, or the glass turntable's diameter.

What the features mean for you
The white finish is tied to the exact suffix
The source listing uses the shortened CHM770 name, but its structured model hint specifies CHM770W. Commercial Chef's product page names CHM770B as black and CHM770W as white; the family manual's cover lists CHM770B, CHM770W, and CHM770SS. This supports keeping the white W variant as its own model rather than collapsing it into the black or stainless siblings. The historical ASIN B0BGSFH99S has not been verified as a current offer for this exact white suffix, so the purchase route is an Amazon search naming CHM770W. Check the model label and finish in any offer before treating it as this profile. The saved identity evidence is stronger than the old listing title alone, while present marketplace identity remains open.
A genuinely compact stated capacity
Both the product page heading and the family manual specify 0.7 cubic feet. That gives a consistent capacity figure for comparing the CHM770W with larger 1.1- or 1.5-cu.-ft. household ovens, but capacity does not tell you whether a particular plate, bowl, or covered dish will fit. The manual's illustration shows a glass tray and roller assembly, yet it does not provide a tray diameter in the reviewed material. If the shape of cookware matters, ask for the exact cavity and tray measurements or measure the items you use most. The comparison therefore records the published cavity volume while leaving turntable diameter unknown; it does not convert a compact capacity rating into a promise about dish fit.
Separate cooking output from electrical consumption
The manual's specification block labels 700 W as MWO Power and 1,100 W as Power Consumption, with 120 V and 60 Hz shown for the latter. The maker product page also lists 700 watts of power, consistent with the manual's cooking-output figure. These wattages describe different things: use the 700 W value when comparing stated microwave output, and do not substitute it for the electrical load when checking a circuit. The manual's grounding section further specifies a 15-amp electrical requirement and recommends a separate circuit serving only the oven. Follow the rating plate and current instructions for installation; this profile does not infer performance time from the output figure or supply a personal cooking test.
Preset controls sit alongside manual settings
The maker page lists ten microwave power levels, defrost by time or weight, a timer and digital clock, one-touch express cook from one to six minutes, six preset menus, and a child safety lock. The manual describes the Auto Menu as instant settings for six popular foods and documents numbered controls, time cooking, a multi-stage program, and a Start plus 30-second function. This is a concrete set of everyday shortcuts, with manual time and power settings available as well. Neither source describes these preset menus as sensor cooking, so the sensor attribute stays unconfirmed. Buyers who require documented sensor adjustment should compare against a model whose exact instructions explicitly say it senses moisture or adjusts cooking from a sensor.
Counter placement has specific clearance requirements
The manual says to place the microwave on a flat, stable surface and leave eight inches above, four inches behind, and two inches at each side for airflow. It also says not to block openings or remove the feet. Those instructions support a countertop placement and make the surrounding space a meaningful part of the fit decision. Commercial Chef's product page and the manual do not establish a model-compatible built-in trim kit, so a cabinet conversion should not be assumed. There is a further measurement issue: the article gives unit dimensions of 17.75 by 13.13 by 10.25 inches in width, depth, and height order, while the manual lists outside dimensions of 9 9/16 by 17 9/16 by 12 9/16 inches in height, width, and depth order. Since those figures do not reconcile, this review does not choose one set as definitive. Obtain the revision-specific measurements before planning a tight opening or shelf.
Household classification and finish details
The manual says the appliance is for household use only and is not designed for industrial or laboratory use. That supports treating CHM770W as a household microwave rather than foodservice equipment, despite the Commercial Chef brand name. The model page identifies the control style as push-button with a digital LED display and describes a grip-handle door. It does not provide enough material in the reviewed source to confirm a stainless interior, a trim kit, or a specialized service-duty rating. Keep the actual white suffix visible when comparing it with other CHM770 family members and use the manual's electrical and clearance instructions for the exact unit. The sources support a small household role; they do not establish that the appliance suits a shared commercial kitchen.
What else to compare
For more capacity and output, the LG LCS1114SB is 1.1 cu. ft. with 1,000 W and a documented 12-inch turntable. Galanz GLCMKZ11GNR10 also has 1.1 cu. ft. and 1,000 W, with a documented 12.4-inch tray and Surf Green finish. For a maker-classified foodservice option, Amana Commercial RCS10DSE is 1.2 cu. ft. and 1,000 W with dial control. CHM770W is smaller, white, and offers simpler household presets; its turntable size is not established.
Before you buy
Is CHM770W the white version?
Yes. Commercial Chef identifies CHM770W as white and CHM770B as black; the manual also lists the stainless CHM770SS sibling.
Is the microwave output 700 W or 1,100 W?
The manual labels 700 W as microwave output and 1,100 W as power consumption at 120 V/60 Hz. They are different ratings.
Will it fit on my counter or in a cabinet opening?
The manual gives counter ventilation clearances, but its exterior measurements conflict with the maker page. Confirm exact measurements before planning a tight space; no trim kit is confirmed here.
Where can I check the current price?

The decision
Choose CHM770W when its white finish, 0.7-cu.-ft. capacity, and straightforward preset/manual controls meet your needs. Verify the exact suffix and current product measurements before purchase, and do not assume sensor cooking, turntable size, or a trim-kit path from the available documents.
