What the stated wattage costs to run
The Sunbeam listing states 120 watts. The NBKLS listing states “75 watt-hours” where watts belong, which mixes power and energy units, so no cost figure can be computed for it. The other three state no power figure at all. For a pad used an hour a day, the electricity cost is negligible next to the purchase price; the wattage matters more for how hot the pad can get.

Heat settings, timers and shut-off
| Pad | Heat settings | Size | Shut-off | Warranty |
|---|---|---|---|---|
| Sunbeam XXL 20×24 | 4 | 20 x 24 in | 2-hour auto-shutoff | Not stated |

Three of the five state 6 heat settings; the Sunbeam states 4 and the Zolly 8. Four state timer settings with auto shut-off; the Deepsoon and Sunbeam state a 2-hour cutoff. None of the five states a warranty term. The vilicert is the only wearable with a belt; the Zolly is the only cordless one.
Who should not buy these
If you need a pad for clinical pain management, talk to a doctor first; these are home comfort pads, not medical devices. If you want full-body heat, none of these covers more than the 40 by 20 in Deepsoon. And if you need a pad you can leave on all night, none of these is rated for that; every pick here shuts itself off.

Score notes
The Chill Score weighs performance 30, build 20, value 20, safety 15 and warranty 15. Here, performance covers stated heat settings, size and features. Safety comes from stated protection features: overheat protection and auto shut-off. No electrical safety certification is stated for any pick, and no warranty term is stated either, so warranty is zero for all.
| Product | Chill Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Sunbeam XXL 20×24 | 9.6 | 30 | 21 | 21 | 5 | 0 |
| Deepsoon 40×20 | 9.6 | 29 | 20 | 21 | 7 | 0 |
| vilicert 12×24 Belt | 9.6 | 28 | 20 | 21 | 7 | 0 |
| NBKLS 12×24 | 9.5 | 27 | 20 | 20 | 5 | 0 |
| Zolly Cordless | 9.4 | 23 | 19 | 19 | 5 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Sunbeam has the fullest stated power spec for the money. The Deepsoon suits buyers who want the largest pad with the most stated safety features. vilicert is the wearable pick with a belt. Zolly is the cordless outlier for period cramps, not a general pad.
Common questions
How many heat settings do I need?
Three of the five picks state 6 settings, the Sunbeam states 4 and the Zolly 8. More settings give finer control over warmth. If you run hot or cold, pick the 6-setting range; if you want simple, 4 is enough.
What does auto shut-off do?
It turns the pad off after a set time. The Sunbeam and Deepsoon state a 2-hour cutoff; the vilicert and NBKLS state 1, 2, 4 or 6 hour timers. It is a safety feature, not a substitute for supervision.
Can I wash a heating pad?
Four of the five state machine washability: the Sunbeam is machine washable and dryer-safe, the Deepsoon machine wash-safe, the vilicert has a machine-washable cover, and the NBKLS supports gentle machine wash. Always unplug and remove the controller first, and make sure the pad is completely dry before use.
What is moist heat?
Spraying the fabric with water so the heat penetrates more deeply, per the Sunbeam, vilicert and NBKLS listings. It is a maker-described technique, not a separate mode on these pads.
Do any of these state a warranty?
No. None of the five listings states a warranty term. The score reflects that: warranty is zero for every pick.
Is the Zolly a regular heating pad?
No. It is a cordless wearable for period cramps with heat and massage, 7.1 by 1.3 by 3.2 in. If you want a flat pad for back or shoulders, pick one of the other four.
