RV Power Cords

If you are in need of a new RV Power Cord, Hanna Trailer Supply is your one stop shop. We carry a wide selection of power cords from manufacturers like Camco, Voltec, and Furrion. RV Power Cords come in a variety of lengths and styles to fit your particular needs. You will not always be able to park right next to a power pedestal at the campground, so it is a good idea to have a few different lengthed cords to make plugging in quick and easy. If you only have one RV power cord, it is not a bad idea to purchase an additional cord so that you can connect to far-away power sources.

RV Plugs, RV Plug Adapters, and Receptacles

If you have a 30 amp RV, we recommend you have a 50 amp to 30 amp RV plug adapter, and a 15 amp to 30 amp RV plug adapter. A 50 amp to 30 amp RV plug adapter has a 50 amp male plug, and a 30 amp female receptacle. A 50 amp to 30 amp adapter will allow you to plug your RV into a 50 amp outlet. A 15 amp to 30 amp RV plug adapter has a 15 amp male plug and a 30 amp female receptacle. It is very uncommon that you would end up at a park where there is 15 amp power, but in the case that you would, you would want to have a 15 amp to 30 amp adapter. You can plug your RV's 30 amp power cord into the 15 amp to 30 amp adapter, and use the 15 amp power provided by the pedestal. You will not be able to run the same appliances you can with 30 amp power, but 15 amp service is better than no service.

Surge Protectors

RV surge protectors come in portable and hardwired models, and they come in 30 amp and 50 amp models. Surge protectors monitor the amount of power that is being sent to your RV, and they continually protect your RV and its appliances from surges, mis-wired electrical pedestals, high and low voltage spikes, and other miscellaneous electrical problems. It is a good idea to get an RV surge protector so that you do not need to pay for costly repairs down the road. We have a variety of portable and hardwired surge protectors from Camco, Progressive Industries, and TRC.

Inverters

Inverters convert 12 Volt DC power from your vehicle's battery into 120 VAC power, which is standard household electricity. They provide electricity to your RV when your are unable to connect to a generator or power pedestal. Inverters are a great source of supplemental power for your RV electrical system.

Switches

Hanna Trailer Supply carries a wide selection of replacement switches for your RV. We have motor switches, battery switches, on/off switches, and double, triple and quadruple rocker switches in various sizes and colors to fit your needs.

Cable Hatches

Cable hatches are mounted on the outside of your motorhome or trailer, and they serve as access ports for your vehicle's power cords. Over time, they become damaged by harsh weather conditions and UV rays. We have a variety of RV cable hatches from JR Products and RV Designer to replace your broken or damaged hatches. Hatches come in different shapes and sizes, and they are designed to accept 30 and 50 amp power cords.

Fuses and Circuit Breakers

Hanna Trailer Supply has a wide selection of fuse boxes, circuit buses, and circuit breakers for your RV. Whether you are replacing an old fuse, or working on building your own system, Hanna RV has your electrical needs covered.

Solar Panels and Chargers

Solar Panels provide your RV with peaceful and quiet electricity. They are a great alternative to noisy generators. They are also a great option if you like to RV in remote locations where you don't have access to shore power. We carry a wide selection of solar panels and chargers from trusted manufacturers like Samlex and Wirthco.

Converters and Chargers

A converter is a device that almost every towable RV comes with. Converters take AC power and convert it to DC power. There is a relay switch inside a converter that takes your batteries out of the circuit. It supplies power to the DC appliances in your vehicle so that your battery does not need to power them. The converter's other job is to convert the AC power to DC power and charge the house batteries in your rig.
