⚡🔌 NEMA 5‑15R to 1‑15P Power Adapter
(Grounded 3‑Prong Receptacle → Ungrounded 2‑Prong Plug)
This adapter converts a standard grounded 3‑prong outlet (NEMA 5‑15R) into a 2‑prong ungrounded plug (NEMA 1‑15P). It’s used to connect older electronics or travel devices that lack a ground pin.
🔧 Adapter Form
- Input: NEMA 5‑15R (standard 3‑prong grounded outlet)
- Output: NEMA 1‑15P (2‑prong ungrounded plug)
- Grounding: Often includes a metal grounding tab or loop for optional chassis ground
- Voltage: 120V AC
- Current: Up to 15A
- Common aliases: “3‑to‑2 prong adapter,” “ground lift adapter,” “cheater plug”
🖥️ Compatible Devices
🟦 Legacy Electronics
- Vintage radios, cassette decks, CRT TVs
- Older laptop chargers and wall warts with 2‑prong plugs

- 🧪 Bypassing ground pin for temporary setups (with caution)
🧠 Signal Format
- ⚡ Passes 120V AC from wall to device
- 🔌 Converts 3‑prong grounded outlet to 2‑prong ungrounded plug
- 🧲 Optional ground tab can be screwed to outlet plate for chassis grounding
⚠️ Things to Watch Out For
- 📉 No true ground protection — use only with double‑insulated or low‑risk devices
- 🔌 Not suitable for high‑power or grounded appliances (e.g., refrigerators, microwaves)
- 🧯 Always confirm device compatibility and local electrical codes
🛠️ Quick Tips for Beginners
- 🧭 Look for “NEMA 5‑15R to 1‑15P” or “3‑to‑2 prong adapter” on packaging
- 🔌 Use only with devices that don’t require a ground pin
- 🧪 If unsure, check for double‑insulated symbol (square within a square) on device
- 🧯 Never use with surge protectors or grounded medical equipment
