Manufacturer description

The TENINYU Grounded Adapter turns a single 2-prong wall outlet into three 3-prong AC outlets. You can plug grounded-plug appliances into older two-slot receptacles without replacing the receptacle. It is UL Listed and rated at 125V / 15 Amp / 1875 Watts, and the shell is fire-resistant ABS. Grounding works through the faceplate screw. Screw the adapter onto the cover plate of a grounded outlet box and the ground path is complete. If the box itself isn't grounded, you still get three outlets but no ground protection, so check the box before you plug in grounded equipment. There's nothing…

Frequently Asked Questions

Will this let me plug a 3-prong appliance into a 2-prong outlet?

Yes. The adapter plugs into a 2-prong polarized outlet and gives you three 3-prong AC outlets for appliances like hair dryers, straighteners and lamps.

Is the adapter actually grounded once I plug it in?

Only if you attach it to the faceplate screw of a grounded outlet box. Grounding runs through that screw. If the box isn't grounded, the adapter gives you outlets but not ground protection.

Can I run a hair dryer and other appliances at the same time?

It is rated 125V / 15 Amp / 1875 Watts total, shared across all three outlets. A hair dryer is a listed use, but the combined load of everything plugged in has to stay under 1875W.

Will it block the other outlet on my wall plate?

No. The manufacturer says the compact design won't block the second outlet on a standard duplex receptacle.

Does it need any installation or tools?

No wiring is needed. You just plug it in. For grounding, fasten it to the faceplate screw of a grounded outlet box. Check the product listing for current warranty terms.
