Connects a 50-amp RV power cord to a standard 15-amp household outlet. Detachable female 50A receptacle with carrying ring separates from the 15A plug body for easier storage. Dogbone style with 12" cord. Durable PVC construction. RV still limited to 15 amps when using this adapter.
50-amp RVs â typically larger motorhomes, fifth wheels, and high-end travel trailers with dual air conditioners and larger electrical loads â are built around 50-amp NEMA 14-50 service. But campgrounds, home driveways, and many older sites may only have a standard 15-amp household outlet available. The Valterra A10-1550DAVP bridges that gap, allowing a 50-amp RV power cord to connect physically to a standard 15-amp outlet for temporary use.
What sets the A10-1550DAVP apart from the non-detachable A10-1550 is its detachable design: the female 50-amp receptacle separates from the 15-amp male plug body, connected by a 12" dogbone-style cord. A carrying ring on the female end makes it easy to grab, orient, and connect the large 50-amp plug to the RV's power cord without wrestling with a rigid adapter in tight spaces. The two-piece detachable design also makes the adapter more compact for storage in your RV's utility compartment. Molded from durable PVC for long-term outdoor use.
The 50A female end separates from the 15A male plug on a 12" cord â easier to handle in tight spaces and more compact for storage
Ring on the 50A female receptacle makes it easy to grip, orient, and connect the large plug to your RV's power cord
12" dogbone cord between the two connectors keeps the adapter flexible and easy to manage at the hookup pedestal
Durable PVC construction holds up to outdoor use at campgrounds, driveways, and temporary power locations
This adapter allows your 50-amp RV power cord to physically connect to a 15-amp outlet â but the available power is still limited to whatever the 15-amp circuit can supply. Using this adapter does not give your 50-amp RV access to 50-amp power. What this means in practice: âĸ Your RV's total power draw must stay within 15 amps (approximately 1,800 watts at 120V) at all times âĸ 50-amp RVs are typically designed for 240V/50A service â on a 15-amp circuit, only one leg of power is available (120V), not two âĸ Air conditioners, electric water heaters, and microwave ovens each draw close to or more than 15 amps alone â running any of these will likely trip the breaker âĸ With a 50-amp RV on 15-amp service, basic loads (lights, refrigerator, battery charging, fans) can typically be run safely with careful management This adapter is best for: âĸ Short-term stays at a home driveway or non-RV location where 50-amp service is unavailable âĸ Charging batteries and running minimal loads while waiting for proper 50-amp service Never exceed the 15-amp capacity of the outlet or circuit. Doing so risks tripping breakers, overheating wiring, or creating a fire hazard.
Valterra offers the 15A-to-50A adapter in two configurations: A10-1550DAVP (This Product â Detachable): The 50A female receptacle separates from the 15A male plug body on a 12" dogbone cord. The detachable design is easier to handle in tight spaces, the carrying ring on the female end simplifies connection to the RV's power cord, and the two-piece format is more compact for storage. A10-1550AVP (Non-Detachable): A single-piece compact adapter with both connectors as a fixed unit â shorter overall, simpler, but less flexible to handle with the large 50A receptacle right at the 15A plug. For 50-amp RVs where the 50A power cord end is large and the hookup area is tight, most users prefer the detachable dogbone style â the extra reach and carrying ring make connection noticeably easier.
Connecting Your 50A RV to a 15-Amp Outlet: 1. Locate a 15-Amp Outlet: Find a standard 15-amp household outlet â home garage, exterior outlet, or campground pedestal with 15A service 2. Check the Circuit: Confirm the outlet is on a dedicated or lightly loaded 15-amp circuit â avoid outlets shared with other high-draw appliances 3. Plug Adapter into Outlet: Insert the NEMA 5-15P male end of the adapter into the 15-amp outlet 4. Connect RV Power Cord: Plug your RV's 50-amp power cord into the adapter's NEMA 14-50R female receptacle â use the carrying ring to orient the large plug correctly 5. Manage Your Load: With only 15 amps available â and only 120V single-phase, not 240V â be very conservative about which appliances you run. Lights, refrigerator, and battery charging are typical safe uses Never exceed the 15-amp capacity of the source circuit. Use proper 50-amp service whenever it is available.
