Best Surge Protector for Pellet Stove (2026): 5 Compared

Treybair lists a 3-outlet surge protector for 110 or 120V 15A with a built-in LED voltage display showing real-time metrics. The listing describes custom voltage thresholds of 80-140V, dual-mode response with refrigerator delay over 180 seconds and TV instant reaction, plus a 2 Year Manufacturer warranty. It weighs 4.8 ounces at 3.14 by 2.36 inches. No joule rating is stated. The dual-mode response is the clever part: refrigerator mode with high-load delay over 180 seconds for motor loads, instant reaction for TVs. The listing recommends keeping the custom range at 80-140V to avoid failure to auto-restore. The flame-retardant material claim meets UL94V-1, per the title.
