Frequently Asked Questions

Does this actually ground my three-prong appliance?

It provides a ground path through the metal tab that fits under the outlet plate screw, so grounding only works if that screw connects to a grounded box. JACKYLED specifically notes that using the adapter on an ungrounded 2-prong outlet is not recommended.

How much power can it handle?

It is rated AC 125V/15A with a 1875W maximum wattage, which covers most household, office, and light machinery appliances. Loads above 1875W should go into a properly grounded outlet instead.

Is it safe near heat?

The housing is molded from fire-proof PBT that resists temperatures up to 392F, and the unit is ETL Listed. Keep the load within the 1875W rating.

Will it work for travel to Japan?

Yes. Japanese wall outlets are two-slot, so this adapter lets you plug a three-prong device in. It is small enough to carry in a briefcase or laptop bag. Confirm your device supports the local voltage before plugging it in.

Does it fall out when a heavy cord is plugged in?

JACKYLED states the adapter fits snugly into the wall outlet and stays put even with a heavy cord attached.

  • 【Polarized Plug】The 3-prong to 2-prong grounding adapters is polarized and better than the un-polarized plug adapters, because polarized plugs only allow you insert the plug into the outlet slots in one direction, wide blade to wide slot, narrow blade to narrow slot, which ensures neutral-to-neutral, hot-to-hot and provides a measure of safety for the appliances and house wiring to be aligned in terms of polarity. This also explains why most household appliances’ plugs are polarized.
