Check the specification table above against one or two close alternatives — on price and spec fit, not on star ratings.

The SerBion 3 Prong to 2 Prong Outlet Adapter solves a problem every older home eventually hands you: a grounded appliance plug and a two-slot wall outlet. This four-pack of ETL-certified adapters is built from fireproof material rated to 1382F, and each unit handles up to 1875 watts at 125 volts and 15 amps, so it covers household appliances rather than just phone chargers and lamps. The polarized design is the part worth paying attention to. A polarized plug only seats one way, keeping neutral to neutral and hot to hot so the circuit's polarity stays aligned.

Frequently Asked Questions

Does this adapter actually ground my appliance?

It provides a grounding path through the metal plate that mounts under your outlet's cover-plate screw. That only grounds the device if the wall box itself is grounded; ungrounded older boxes cannot be fixed by any adapter.

How much power can it handle?

Up to 1875 watts at a maximum of 125 volts and 15 amps, which covers most household appliances on a standard branch circuit.

Is it safe for high-heat use?

The housing is made of fireproof material rated to 1382F and the adapter is ETL certified. Stay within the 1875W rating and follow the appliance manufacturer's instructions.

What does polarized mean and why does it matter here?

A polarized plug inserts only one way, keeping neutral to neutral and hot to hot. That alignment is safer than a non-polarized adapter that can be flipped either direction.

How big is each adapter and how many come in the pack?

Each one measures 1.69 x 1.37 x 1.75 inches and the order includes 4 packs, so it fits behind furniture or in a travel bag with spares on hand.
