Kanayu shore power adapter 30A L5-30 to 5-15/5-20, 3 FT heavy-duty marine RV pigtail

Kanayu's 3-foot shore power adapter converts a NEMA L5-30 30A locking inlet to common 5-15/5-20 household or T-blade 5-20 outlets for temporary RV, boat, or generator connections.

This heavy-duty adapter cable gives you a safe, compact way to draw power from a 125V L5-30 source when only 15A or 20A receptacles are available. Built with STW 10AWG/3 conductors and ETL-listed components, the cord is designed for short, on-deck or campsite use where full-time shore wiring isn't required. It does not convert voltage — it adapts plug shapes and limits current to the appropriate maximums for the connected receptacles.

How does this adapter work with my shore power or generator?

The adapter accepts a NEMA L5-30P 30A locking plug and presents a standard household 5-15R outlet and a T-blade 5-20R outlet on the other end. It routes the live, neutral and ground conductors through a heavy-duty cable while the locking plug secures to L5-30 receptacles commonly found on generators and shore pedestals. The unit is rated for 125 volts and will deliver up to the amp rating of the attached receptacle.

• Input: NEMA L5-30P 125V 30A locking plug for secure connection.
• Outputs: NEMA 5-15R (15A) and NEMA 5-20R T-blade (20A) receptacles.
• Cable: STW jacketed 10 AWG, 3-conductor for durability and heat resistance.
• Use-case: temporary power only—does not change voltage.

Will this adapter safely power my appliances and electronics?

The cable provides a convenient path to lower-amp outlets but you must observe each outlet's maximum rating. A device plugged into the 5-15R is protected by that outlet's 15A limit; the 5-20R is limited to 20A. Because the L5-30 source can supply greater current, do not overload the connected devices or assume built-in circuit protection beyond the receptacle ratings.

• Maximums: 15A for 5-15R, 20A for 5-20R — respect device power draws.
• Do not exceed 125 volts; the adapter is designed for 125V service only.
• Not compatible with 250V 20A (NEMA 6-20) outlets or equipment requiring 250V.
• Best for small appliances, chargers, lighting, and low-draw marine/RV gear.

How rugged and reliable is the construction for marine or RV use?

Kanayu built the 3-foot adapter with a thick STW jacket and 10 AWG copper conductors to stand up to short-term exterior use. The L5-30 locking plug ensures a secure connection at shore pedestals or generator outlets, and the molded end housings minimize strain at termination points. The design is intended as an adapter/pigtail — rugged for travel and seasonal use, but not a long-term replacement for properly wired shore power cords.

• Durable STW 10AWG/3C cable resists abrasion and outdoor exposure.
• Molded locking L5-30 plug for vibration-resistant connections.
• Compact 3-foot length keeps lines neat and reduces trip hazards.
• ETL-listed components for basic safety verification.

Who this is for: The Kanayu 3 FT 30A to 15A/20A shore power adapter is aimed at boat owners, RVers, and generator users who occasionally need to plug standard 15A or 20A devices into a 30A L5-30 source. It’s ideal when you need a short, dependable pigtail to power chargers, appliances, or tools on a temporary basis. Avoid using it as a permanent wiring solution or for high-draw equipment that requires full 30A service; instead use it to bridge outlet types safely and conveniently while observing the adapter’s rated limits.
