I use this to power my flux capacitor. Works great, and the twist lock connector means you won't have to slide down the cord to plug it back in.

It’s fine, good price.A little advice, buy longer than you think you need. Not that you want lots of coils, but you don’t want to be skimping and need five extra feet.

This works well and we have it for double purpose of connecting to a transfer switch on my home if/when needed and for connecting to generator for a race car trailer. Seems well made and so far has worked great.

The pictures are kinda all over the place for this product -- a typical case of too much Photoshop. I am always generous with my pictures so you can see exactly what you're getting. You can see the plug and receptacle detail closely.The L14-30R end fits in a generator inlet box fine since the tabs/wings start more than halfway back. Some others like the Parkworld (https://amzn.to/49RaJUk) do not. Overall both the receptacle and plug ends are quite compact so they should fit ANYTHING, however, there is a small mismatch in the diameters, so that's kinda odd.The male plug end is bare brass which is OK. I do like the nickel-plated ends better like on the Parkworld if you are not using this with a generator inlet box. Nickel-plating resists corrosion much better.This one comes with a kinda cheap plastic holder which I won't use. The Parkworld comes with a wonderful Wrap-It Easy-Carry or LuBanSir style carry handle nylon strap with Velcro. A cheap, plastic strap is not a deal-breaker since you can get those separately, but, hey, it's $8.The wiring is labeled (UL) SJTW 4-conductor 10 awg, however, I would rate its stiffness as average/medium. I would give its stiffness 3 stars.If stiffness is one of your top priorities like mine, then look to the RVMATE (https://amzn.to/3JwIn7l) or the RVGUARD (https://amzn.to/4aQdLcH) which I give a stiffness rating of 5 stars. Those latter two are identical for all intents and purposes and what I ultimately went with since those are the MOST flexible generator cords I've found (even better than SJOOW rubber cords which I would rate 4 stars). The two RV* brands have no wings on their L14-30R ends, so no generator inlet box problems, either.All of these (oviitech, Parkworld, RVMATE, and RVGUARD) are the lowest priced generator cords on Amazon, with other more-inferior cords costing easily 1/3 more. I also prioritize black wires since I'm tired of cleaning yellow, orange, green wires since they pick up black marks from everything. There are some length differences such as this oviitech is the only one available in a 20 foot length.This is my short-list. you can do worse, but not better.

I'm very happy with this 50' 4 prong extension cord. It has some weight to it which makes if feel like it will get the job done. It coils nicely and looks good. The connectors fit nice and lock in place. I tested it with my home and it performed well.

I figured this product was going to be another piece of cheap Chinese made garbage coming from China. To my surprise, the quality was there. Price was fair, the 40-foot length was available less than the standard 50 feet (which saved additional money) and sent in a very good quality package which kept the shipping costs low. Delivery time was fast too!I would buy from this seller again.
