Great Product

Bought this because sometimes there is no 50 amp service in the RV parks I use. This will increase the amps that I can use in some RV parks. It is important to understand that this doesn’t combine for 45 amps. Without going in to a long explanation of how the amps work but it does allow for using more electrical items than a straight 30 amp plug. Can’t yet comment on whether it’s waterproof but it appears to be, just haven’t used it under wet conditions yet. Also, a little pricey, but it does address a power issue. Recommended.

great if you understand the limitations

As usual, most bad reviews for this product are from people who don't understand how it works or what it can and cannot do based on the laws of physics. If you know what you're getting into and what the limitations are, this is a very useful device. ;) We had put in a 30-amp socket for our trailer at our house in the past but recently upgraded to a dual a/c 50-amp trailer. Luckily we have a non-GFCI 20-amp outlet nearby in the garage so I bought this to be able to run both air conditioners when we're using the trailer as a guest house. In conjunction with our Progressive Industries PT50C (http://smile.amazon.com/gp/product/B002UC4SWM) I'm able to monitor the current on each leg to know what I can and can't run simultaneously. For those of you who may not know, a 50-amp RV connection actually gives you 100 amps via two independent out-of-phase 50-amp legs. Some devices in your RV are on one leg and some are on the other. While watching the above-mentioned power monitor, you can turn things on and off to figure out which devices are on which leg and how much current they draw. What this "cheater" plug gets you is a 30-amp leg and a 15/20-amp leg, so you still have to be aware of what you're running but you're better off than being stuck with just 30 amps. My living area a/c, microwave, and fridge are on leg 1 (the 30-amp connector). My bedroom a/c, water heater, and battery charger are on leg 2 (the 15/20-amp leg). So I know if I keep the water heater on propane and haven't recently connected drained batteries, I can safely run the bedroom a/c at the same time as the living area a/c on the other leg. Note that you cannot use this with a 15/20 amp GFCI outlet. It will trip the breaker. This means you won't be able to use this at most RV parks because code requires those to be GFCI outlets.

great product works fantastic

Great Item. Works on champion 4000 watt generator since it does not have a GFI plug. ran AC and microwave. And very heavy duty.

My unit is equiped with a 50 amp connection, but only requires 30 to run just about everything. It gives me the ability to accept a 30 amp when 50 amp isn't available. I'm still able to draw 45 amps of power, which is plenty to run my unit without the addition of a second generator.

must have for every 50A RV. keep in mind - For this to work properly you must have both ends plugged in for this to feed power to both legs of power. If you cant plug in both, you will need a regular 30A adapter as this wont work.

Works When You Need That Extra Power

If you find the place you are setup with your RV does not have 50 amp service, and has an older 115 volt plug, will not work with circuit breaker 20 amp, you can gain a little extra to up your power needs. I have just such a place and this will fit the bill to allow for simultaneous use of AC, hot water heater(electric) and microwave power, beats having to stage usage.

This came in so handy when we were staying at ...

This came in so handy when we were staying at a vacation rental with family. We use 50 amp, only a 30 amp hookup. Used this adaptor to run an extension cord to a plug in the houses garage and to the 30 amp plug. We did keep the hot water heater off so we could keep both ac's running in Florida's 90+ degree weather.

Works as Advertised

The cord arrived on time and as advertised. It works as advertised and I highly recommend the cord when traveling from place to place and do not know what power will be available in various parks. It is made of a high quality material and withstands the various weather elements.

RV camping

We ordered 2, one for our motorhome and one for our parents to use with their 5th-wheel. It takes a 30 amp & 20 amp and converts them to a 50 amp (45 amp). Can't wait to try it out. It seems high quality.

Works perfectly within it's limitations.

Works perfectly within it's limitations. As has been stated many times, this adapter WILL NOT WORK on any GFCI protected circuit. Because of this, you will probably have some issues trying to use it at an RV park. That is not what I bought it for though. For me, it allows me to hook up power cords to two separate non GFCI circuits when I find myself staying at a friend or family's private residence. Since most people will not have a 50 amp hookup at their house, it's the only way to run 2 air conditioners if necessary on a hot summer day. You always have to be mindful though that you are not hooked up to a real 50 amp service (which is actually 50 amps X 2 or 100 amps total capacity at 120 volts), and be careful of how much load you are putting on either circuit. A previous reviewer complained that it was wired incorrectly because in their particular instance, the 30 amp side was connected to the lower load side of their RV, and the 15 amp side was inadequate for the higher load side. In truth, there is no standard whatsoever as to a higher and lower side of a 50 amp plug, and it's pretty much just luck of the draw. Most manufacturers try to balance the load equally between the two sides, but in real use it also depends on which side the high draw items you are trying to use are on at the same time. If this is an issue, you can swap the hot feed wires in your RV, either at the incoming receptacle (if used), transfer switch, or breaker box.
