MARSTEK 14AWG 20A IP67 extension cord

The MARSTEK power extension cord provides a 6.6 ft 14AWG cable rated for 20A at 125V. It features a 3-prong piggyback plug and an inline on/off switch with a high-visibility light button. The IP67-rated housing is made from flame-retardant PA66 for waterproof and dustproof protection. It is UL listed for safety compliance.

Sustained 20A load handling and weather resistance

The cord is rated for continuous 20A AC/DC operation at 125V, supporting high-current appliances without derating. The IP67 enclosure protects the inline switch from water immersion and dust ingress during prolonged outdoor use. Flame-retardant PA66 housing maintains structural integrity under sustained thermal load. The inline switch allows direct load control without unplugging the device.

Replaces fixed outdoor outlets and unprotected cords

This cord upgrades installations where a switched connection is needed at the point of use, such as landscape lighting, fountain pumps, or seasonal decorations. The jump is worth it when replacing permanent wiring runs that lack local switching or when standard indoor cords fail in wet conditions. It is not suited for buyers needing longer runs beyond 6.6 ft or higher voltage than 125V.

Questions about this item

Does the inline switch housing stay cool during continuous 20 A loads?

The flame-retardant PA66 housing is built for 20 A at 125 V; no temperature-rise figure is published.

What connectors must my existing cords have to use the piggyback plug?

The piggyback plug accepts a standard 3-prong North-American plug on its face and provides a matching 3-prong receptacle on the back.

Will the IP67 rating protect the switch if I leave it connected to older outdoor tools in wet weather?

Yes — the switch assembly carries an IP67 rating, so it remains sealed against dust and temporary immersion while powering legacy equipment.
