Frequently Asked Questions

Will this fit a 3-prong grounded plug?

No. This is a 2-prong ungrounded Type A adapter with three 2-prong outlets, so grounded 3-prong plugs will not fit. Use a grounded adapter or strip for those devices.

How much power can it handle?

ETwinCoo rates it for a maximum of 125VAC, 15A, and 2500W. Add up the wattage of everything you plug in and keep the total under that ceiling.

Can I use large boxy plugs without blocking the other outlets?

Yes. The side outlet is designed for large adapter-shaped plugs, and the 180-degree rotating plug lets you angle the unit so it does not obstruct the neighboring wall outlet.

Does it work overseas?

It is built for Type A outlets, so it works in the United States and Taiwan. It is not a voltage converter and will not fit Type C, G, or other foreign outlet shapes.

Is it worth buying, and what do other shoppers say?

It ships as a 2-pack, so you get two adapters. Check the listing for current pricing.

What warranty comes with it?

ETwinCoo states a lifetime warranty and directs buyers to contact its support team with questions. Confirm current terms on the product listing before purchase.
