Conntek 20571: 30 Amp L5-30 Locking Style Generator Extension Cord, 25 Feet

Very sturdy 50-foot long power cord with good and well-fastened connectors and sizable wiring. Being so sturdy, it should hold up well for periodic use when hunting and camping, to bring standard household-level (120-volt) electricity from my gas generator into my 7'x12' converted cargo camping trailer in order to power 120-volt devices like a home freezer, a meat grinder, a television screen for viewing the day's nature photos, my computer, an electric heater, coffeepot, or other such devices (but NOT all at the same time, of course). Nevertheless, the 30-amp power cord allows for safely powering two standard 15-amp electricity circuits in the trailer, and thus simultaneously running more devices such as a home freezer and a meat grinder when butchering wild game out on the prairie or up in the mountain forest, away from civilization. At 50' in length, we will be able to position the generator well away from the trailer, to permit normal conversation during generator use. The cord, being yellow, is less likely to be left behind and lost. Note that the connectors on both ends are the 3-prong (NOT 4-prong) 30-amp twist-type plugs. (The web also shows the 4-prong style, if that is what you need instead.) Also note that this cord could be used in a plug-in type situation, such as in a developed campground or at home or (some) motels, assuming the power source offers a 3-prong 30-amp twist-type electrical receptacle for your use, or assuming that you have a short plug-converter cord to temporarily use to connect this cord to a regular 120-volt receptacle.

Does exactly what it says it does, working as part of a system that let me hook up a our small General iQ2000 portable generator with standard three-prong 5-20R outlets to an external L14-30R generator outlet on our house. Larger generators are easy -- just hook up the generator's L14-30R outlet up to the house's L14-30R outlet with a generator extension cord and you're done -- but the smaller generators need some plug adapting magic.Here's how the connections work: 5-20R three-prong outlet on the Generac iQ2000 -> QuestPro RV Power Adapter 5-20R male to L5-30P adapter -> Conntek 20571 25-foot L5-30 generator extension cord -> AC Connectors ADL530L1430 L5-30P to L14-30R adapter -> L14-30R house external generator outlet.The system won't run our well pump or primary heating systems because the generator only produces 110 volts, but everything else in the house works fine on the little iQ2000. (Note: we do have efficient appliances, an OLED TV, and all-LED lighting, so that helps keep the electric loads down).

Great value for the money

OK, it holds air and there is nothing wrong with the hose, EXCEPT: I call it the "Devil Hose". It is the most tangle, ungiving unmanageable miserable nasty thing I ever had to deal with. I bought it, I use it and I cuss it. All it wants to do is curl-up in that little 10 inch ball it came packed as. You can pull all day and the hose just will not give up a loop. It will pull everything over on the floor and sweep everything off your work bench. I hate this hose! Hard to put away, hard to get out and hard to use. Rather string Barbed Wire! But it holds air and does that well.

By visual and feel it’s good quality product, I bought it for emergencies generator so I must say haven’t used much but I trust it will do it job when I need. Good choice

Its an extension cord, so not much to say. A very heavy extension cord, It is heavy! It put the 'Heavy' in Heavy Duty. It is 10 gauge wire, 3 wires a hot, neutral and a ground, or referred as a 10/3. The overall wire is about same size of a garden hose, so wrapping it up feels more like wrapping up a garden hose full of water, than an extension cord.We had a transfer switch installed to run the well pump during periods of no power from a generator. I love how I can keep the generator in the back yard behind a fence and run a cord to the pump, about 45 feet away, so generator is safe behind a fence, makes it harder to steal the generator when I'm in the shower. This is a 3 prong L5-30 ends rated at 120 volts. This will not run 240 volts as that has a different plug.

Very thick and durable cord! Havent had to “use” it yet but have had test runs. Didn’t get hot and I’m 100% confident this cord will get me thru many power-outages for years to come! Very well made fits in my Champion Generator L5-30 outlet

This is a very good power cable. I am using it with a standard RV inlet and a small generator. No issues. Pretty sturdy cord.

Excellent quality product. works flawlessly

nice cord works well with my generator

Exelente extensión, robusta, viene certificada, en buen presio. Unico problema entre comillas: es bastante pesada

Initially they sent the wrong cord but when I showed them they instantly sent the correct one. It's also very durable so I have to give it five stars!

We use this for supplying a cabin with power from a generator. Works well does not get to hot and is not super unmanageable in the cold
