Kohree RV Power Adapter, 12-Inch

A 50-amp RV inlet and a 15-amp power source use different connectors. This adapter is designed to bridge that gap when the RV has a 50-amp twist-lock inlet.

Its short, 12-inch dogbone format keeps the connection compact rather than providing extra reach.

If you prioritize a simple connection and a visible power indicator, those are the main draws, if you need more electrical capacity or a longer cord, this isn’t the right answer.

Getting the most from it

The Kohree adapter has a NEMA 5-15P male plug rated at 15 amps and 125 volts for the power-source end. Its female NEMA SS 2-50R connector is rated at 50 amps and 125/250 volts and is intended for a compatible RV 50-amp twist-lock inlet. Check the inlet and source labels before connecting, the plug shape alone isn’t enough to establish that the setup is suitable for your RV.

At 12 inches, it’s best thought of as a short adapter, not an extension cord. For example, if a campsite’s available connection is a 15-amp source and your RV has the specified 50-amp twist-lock inlet, the dogbone can bridge the connector difference without adding much cord length. The built-in LED glows green when power is present, offering a quick visual indication. It does not tell you how much capacity is available or whether your RV’s electrical needs can be met.

Why it’s worth it

The practical appeal is the combination of a specific plug conversion, a short format, and an at-a-glance indicator. The locking receptacle has a threaded ring, while the molded cable is described as heavy-duty polyvinyl plastic with 100% copper 10/3-gauge STW wire. The maker describes the molded locking connection as weatherproof, that doesn’t establish that the entire hookup or surrounding equipment is protected in every condition.

A short adapter can make sense when the source is close and the goal is simply to connect compatible fittings. Someone who needs to span a larger distance should look for a suitable longer cord instead. And the rating mismatch matters: connecting to a 15-amp source does not turn it into 50-amp service. The available source still sets the practical limit, so this adapter isn’t a way to run a higher-demand setup beyond what the source can provide.

Key takeaways

• Intended for an RV with a 50-amp twist-lock inlet connecting to a 15-amp power source.
• Male plug: NEMA 5-15P, 125 volts. Female receptacle: NEMA SS 2-50R, 125/250 volts.
• The green LED indicates that power is present, it isn’t a capacity or safety test.
• The 12-inch length is compact, but offers little reach if the connection is farther away.

Should you buy it?

Worth considering if your RV has the specified twist-lock inlet, your available supply is 15 amps, and you want a short adapter with a power indicator. It may not suit you if you need a longer run, a different connector, or enough capacity for electrical demands that exceed what a 15-amp source can supply. Match both ends to your actual hookup and keep the source’s limit in mind before relying on it.
