Cons

✗ Three large plugs at once can crowd a single receptacle face

Manufacturer description

The ETwinCoo 2-Prong/3-Prong Swivel Adapter turns a single wall socket into three grounded outlets without crowding the ones next to it. The 270-degree swivel head is the reason to pick it: you can angle a bulky charger downward behind a nightstand, a sofa, or a TV stand instead of forcing a straight-out plug into a tight gap. Because it converts in both directions, you can run a 3-prong appliance cord off an older 2-prong outlet or plug a 2-prong device into a grounded receptacle, and the polarized blade design means it only seats one way so polarity stays aligned with your house wiring…

SpecPicks Verdict

SpecPicks scored ETwinCoo 2-Prong/3-Prong Swivel Adapter using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. ETwinCoo's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

Does this adapter actually ground my 2-prong outlet?

No. It has a grounding pin and passes ground through when used in a grounded receptacle, but plugging it into an ungrounded 2-prong outlet does not create a ground path. The listing describes it for wall sockets with grounding plugs.

How much power can I run through it?

It is rated AC 125V/15A with an 1875W maximum. That covers lamps, tablets, phones, chargers, and printers. Do not use it for space heaters or other appliances that approach or exceed that ceiling.

Can I plug in three large wall-wart chargers at once?

ETwinCoo states the 3-way head accommodates three large plugs simultaneously, and the 270-degree rotation lets you angle each one so it does not bump the others.

Is it safe to leave plugged in behind furniture?

The housing is PBT fire-proof material rated to withstand 1382F and the unit is ETL listed. The flat wall plug and compact body are designed for tight spots like bedside tables and the back of a sofa.

What warranty comes with it and how many are in the box?

It ships as a 2-pack, and ETwinCoo advertises a lifetime warranty handled through its support contact. Check the product listing for current warranty terms and claim details.
