Manufacturer description
The DEWENWILS 1-to-3 power cord splitter solves a problem every crowded outlet has: bulky wall warts and AC transformers that block the sockets next to them. Each 18-inch cord takes one NEMA 5-15P plug and fans it out to three NEMA 5-15R outlets that extend in different directions, so you can seat three oversized adapters on a single surge strip or a recessed wall outlet without stacking them. Rated for AC 125V, 13A, 1625W, the cord is built from 16/3 gauge SJTW wire rather than the thinner SJT most splitters use, with all-copper conductors, reinforced blades, a double jacket, and…
SpecPicks Verdict
SpecPicks scored DEWENWILS Extension Cord using a rating × review-volume × price-fit model applied to published specs and reviews across the home & kitchen category. DEWENWILS's home & kitchen lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for home & kitchen of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent.

Frequently Asked Questions
How many watts can this splitter handle?
It is rated AC 125V, 13A, 1625W total. That is the combined draw across all three outlets, not per outlet.
How long is the cord?
18 inches. It is meant to add just enough slack to reach a recessed outlet or clear a crowded surge strip, not to span a room.
Will three large plug-in adapters actually fit?
Yes. The three NEMA 5-15R outlets extend in different directions specifically so bulky wall warts and AC transformers do not crowd each other.
Can I use it outdoors for Halloween or Christmas lights?
The 16/3 SJTW wire is weatherproof-rated and holds from -13F to 167F, but DEWENWILS lists the product as indoor. Check the listing for the manufacturer's current outdoor guidance.
Is it safety certified, and how many come in the pack?
It is ETL listed and ships as a pack of three.
