Overview
A 1800-watt commercial microwave with dual touchpads, 0.75 cubic feet of interior capacity, and a stainless steel body built for restaurant and cafe kitchens. Ten preset memory pads come programmed, with room for up to 100 custom settings.
Sharp positions this as heavy-duty rather than countertop-casual: the auto voltage sensor and self-diagnostics point at commercial kitchens that run the unit for hours a day, not occasional home reheating. Its 4-stage programming lets one cycle step through different power levels and times, useful for menu items that need more than a single blast. No rating or reviews are attached to this listing.
- 1800 watts output
- 0.75 cu ft stainless steel interior
- 10 memory pads, up to 100 programmable
- Interior exhaust fan and auto voltage sensor
Who it's for
Built for restaurants, cafes, and other foodservice operations that need fast, repeatable reheating across a fixed menu. Overkill for home kitchens or anyone who just wants a basic reheat button.
Strengths and trade-offs
Drawn from this product's published specifications.
- 10 preset memory pads plus room for 100 custom settings
- 4-stage programming for multi-step heating cycles
- Auto voltage sensor and self-diagnostics for consistent output
- Stainless steel construction inside and out
- 0.75 cu ft capacity limits larger dishes
- No customer reviews yet to confirm reliability
- Commercial-grade programming is more than a home kitchen needs
Performance notes
The 4-stage programming lets a single cycle run through multiple power levels and times automatically, and the double and triple quantity pads adjust heating time when cooking two or three portions instead of one. Self-diagnostics and an auto voltage sensor are meant to keep output consistent under the voltage fluctuations common in commercial kitchens, and an interior exhaust fan is included to help extend the unit's working life.
