NEMA 6-20 Extension Power Cord - 1 Foot, Custom Built, 20A/250V, 12/3 SJT - Iron Box Part # IBX-6153-01-C

Purchased the 6 foot cable to slightly extend my Tesla charger to the wall in my garage. Works just fine, no issues and no determinable voltage drop. Cable warms under load, but not more than the charger's own cable.Using extensions cords is against Tesla's instructions due to the charger not being able to monitor the temperature at the plug and thus being unable to automatically reduce the charging current to avoid a fire. With this in mind, make sure you monitor the heat at the wall plug and utilize a high end industrial plug from an electrical supply store instead of those garbage things at the big box stores. Ensure no insulation is caught between the wire and the plug's terminals as this will heat over time and cause a fire.

The cord was low quality and the prongs fit loosely into the socket. It wiggled around easily when plugged in and could have easily fallen or pulled out with cord movement. The outlet is new and other better quality plugs fit properly.

Just what needed for my SawStop tablesaw Only issue I had was plugging the tablesaw into the extension cord. At first it wouldn’t insert at all. It took s lot of force to connect it but it finally went in. Thought for a moment I’d have to return it for replacement. If not for this I would give it 5 stars.

just needed a decent gauge short ext cord to run from the overhead ceiling plug to the bandsaw ( bandsaw cord isn't long enough to reach straight up to a 7 foot ceiling). a short 3 foot cord did the trick and this seems very sturdy.

This product is exactly what I was hoping for. They provide a choice of connectors, one set is molded to the cable, the other - which I ordered has super heavy duty plugs which appear to be repairable if need be. In the pictures the molded one's looked a little weak to me, but that's hard to say with certainty.

This extension cord works well for me - I use it to provide extra length for my portable AeroVironment EV charger (which accepts a NEMA 6-20 plug) to enable me to plug into a Home dryer outlet (one will also need a simple dryer plug to female Nema 6-20 adaptor for this) to charge my Electric car (Leaf). It is not bulky and does a good job. I have used it in situations where I am visiting friends who live on the outer edge of range of my EV (so I can charge quickly at 220V instead of seeking out public charging stations)

This cord is exactly what I was looking for. I no longer need to pull my compressor out of the corner just to put air in my tires.

Quality is nice and solid. Connections were perfect fitting. Would give it five stars but have only used it three months so unsure of it’s longevity.
