Overview

A small electric plate that keeps a filled mug of coffee or tea warm on a desk, with an illuminated on/off switch and non-slip feet. It does not include a mug and can also be used as a flameless candle warmer.

Reviewers are split on how hot it actually keeps a drink: several describe it as keeping coffee hot through long meetings, while at least one reviewer calls the result only lukewarm and better suited to acting as a coaster. One buyer's fix for mugs with a recessed base was adding a metal washer to the plate as a heat sink.

  • Illuminated on/off switch
  • Non-slip base feet
  • Works as a flameless candle warmer
  • Mug not included

Who it's for

Works for office desks or home workstations where a corded warmer plate can sit within reach and someone wants to sip coffee slowly rather than reheating it. Not a fit for anyone expecting the plate to bring a cold drink back up to fresh-brewed temperature or run cordless.

What buyers say

From Amazon customer reviews.

Most reviewers say it keeps coffee or tea hot enough through a work session, with several long time Salton customers noting it matches an older unit they had used for years. The main complaint is heat output that one reviewer called only lukewarm, and a couple of buyers received units with cosmetic defects that were resolved through returns.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Illuminated switch shows at a glance when it is on
  • Non-slip feet keep it steady on a desk
  • Doubles as a flameless candle warmer
  • Low cost for the function
What to check first
  • Runs on a cord, not battery or wireless
  • Heat transfer suffers with mugs that have a recessed bottom
  • At least one reviewer found the warmth only mild rather than hot

Performance notes

The plate runs on a corded connection with an illuminated switch as the only indicator, and it warms enough that reviewers warn against touching the surface bare handed while on. Mugs with a flat bottom sit directly on the heating surface and hold heat well; mugs with a recessed base leave an air gap that reduces heat transfer, which one reviewer solved by placing a metal washer on the plate first.

Frequently asked

Questions about the Salton SMW12

Common buyer questions answered straight from the product spec data - no fluff, no "it depends".

Does the Salton SMW12 come with a mug?

No, it is a warming plate only and does not include a mug or cup.

Can it be used to melt candle wax?

Yes, reviewers use it as a flameless candle warmer, though very large multi wick candles may not fully fit the rim.

Will it keep a mug hot if the mug has a recessed bottom?

Heat transfer is weaker with recessed-bottom mugs; one reviewer improved contact by adding a metal washer to the warming plate.
