Camco PowerGrip Camper/RV Maximizer 45-Amp Adapter | Combines Power from 15-Amp and 30-Amp Outlets to Generate 45-Amps (55025)

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.

Here is what I know about this cable: 1) if you plug into one generator, the other male end cable is NOT hot! MANY of these review say so. I will post pics to show that it simply is not true. 2) the 120v normal plug end ties ground to ground, hot to one of the 50A hots (the left hot, when looking at ground down), and the neutral ties to neutral, all observable on a VOM. 3) the RV30 plug ties ground to ground, hot to the other 50A hot, and neutral to neutral. 4) the VOM does NOT show the two grounds on these plugs tied together, even though each is individually tied to the ground on the 50A RV end. When running on two inverter GENERATORS ( I know that most people use this at a campground), a Ryobi 1800/2300 and a Predator 3500, What I found was that the AC voltages on EACH pin of the 50A plug were different, and matched the voltages of the generator tied to that pin That is good. This should be able to run each leg of a load panel separately to the maximum running rating of each generator. What I also discovered is that they are not tied in phase like parallel generators. I don't have an oscilloscope, but if I monitor the ac voltage BETWEEN THE HOTS with an ac voltmeter, I can see it cyle between 0 and 245 volts. This will NOT support a 220/240volt circuit, so no trying to run dryers !

Had a shock when we pulled into a campsite (not realizing some are 30amp and some are 50 amp) and only had a hook up cord for a 50 amp so a neighbor (another camper) had an adapter for us to use, so as soon as we got home we order and adapter and it works great.. no more worries..

Ok, this item does work, but almost 100% of parks use a GFI plug for the 15 / 20 amp circuit... which will cause it to trip the moment anything is turned on. I actually replaced the GFI plug with a heavy duty 20 amp plug which I removed when I left the park. You won't always be able to do this, even if you have the knowledge and skills to do it, they might frown on it. I did buy a 30 amp adapter (15 to 30) and plugged in to my 30 amp plug and the one right next to mine that was unoccupied... and the service showed up as 50 amp inside the coach... not that I'd pull that much, but it did see the two circuits. So, take care when buying, and using this plug... I like it, but it does have limits.

These are cheater units giving you more power because your plugging in to two circuits in tandem instead of just one. They are cheap & effective in parks that don’t supply enough power to run an air conditioner in your coach, don’t try to run two which will draw to much power & trip the breaker.

I was so excited for our thirty day camping adventure! This quickly diminished when I got to my first campsite on day four when I needed to use this adapter. NOT ONLY DID IT NOT WORK, but it caused a blown fuse, caused me to run off my battery, draining battery, having no power caused me to spend $250 for mobile RV mechanic only to find it was all caused by this defective adapter. Since I didn’t find out it was defective until 1 week after 30 day return window closed, they will not accept the return! Do not purchase!
