I wanted to be able to leave the cable plugged in, but I didn't want to waste the electricity to power the in-line light in the EV charging able. I suppose the amount of electricity involved is insignificant, inconsequential, and it never pay for itself in electricity saved. Having the in-line power switch is also something I wanted so as to be able to override the car connection quickly. The other way would be to unlock the car and wait for the charging circuit to release the cable to be unplugged. The switch is far faster in an emergency situation. Added benefit: the whole EV connection is about 6 feet longer. That works better for my parking place in the garage.

Solid piece. Exactly what I needed.

Perfect for extra protection. I am also using it as a switch for my EV level 2 charger. Mounting was easy.

I just had a level 2 charging plug installed in my garage. The included charger with my vehicle has a NEMA 14-50 plug. If I leave it plugged in, the charger is powered. I worried about wearing it out prematurely by having it powered all the time and it is annoying to unplug each time I use it. These concerns were fixed with this plug. This switch has thicker wire then the included charger. I have charged my vehicle twice since installing this switch and have had no problems. I have it set to charge at 40 amps on the 220v circuit (rated 50 amps). The charger cord is warm to the touch when charging, but not the switch cord or the switch box itself. The on/off switch is easy to flip and has a cover to protect it that flips up out of the way easily. I mounted to the wall with 4 wood screws (not included) in just a couple of minutes. The switch and extension cord are very heavy duty (and heavy). The value is certainly a personal question, but if you want a heavy duty switch that is robust and doesn't heat up with consistent use. I fully recommend this one. This switch could be used for any situation that requires a 220v 50 amp switch, but EV charging would be the most likely.

Buyer’s Premium

A 15% buyer’s premium will be added to the sale price of all purchases.

Store Auction Lots Condition

All items are uninspected and the condition is unknown unless otherwise explicitly stated. Items labeled as “New” are believed to be unused and in original manufacturer packaging; however, packaging may show signs of storage or handling, and items are not tested unless specifically noted. Individual items are available for inspection at Korting Outlet located at 159 1st Court, Grand Rapids, Michigan 49534 during store hours.

The highest bids serve as legally binding contracts, and all sales are considered final. Items are sold on an “as is” basis, without any guarantees, warranties, or the possibility of refunds, whether written, expressed, or implied. The operational condition of an item may not be known or listed in the item description. While we may provide information on the condition of some items, including items marked as “New,” such information is not guaranteed.

All items are sold with all faults and without any warranty, whether expressed or implied, regarding merchantability or fitness for a particular purpose. The sale is conducted on an “as is, where is” basis with all faults. Buyers are strongly encouraged to physically inspect items before placing bids during the inspection period. Once submitted, bids cannot be withdrawn before, during, or after the auction for any reason.

The buyer acknowledges that these terms, along with other terms outlined below, can only be amended or revised in writing, signed by the auctioneer. Any representations made by Korting or its agents do not alter these “as is, where is with all faults” terms. Descriptions provided on products or through advertising, including condition labels such as “New,” are not guaranteed, and buyers rely solely on their own inspection. While information in sale advertising is believed to be accurate, Korting assumes no responsibility for errors or omissions.

Auction Closing Times

Posted closing times are in Eastern Time and may be extended through dynamic bidding. Dynamic bidding extends the auction close time until there are five minutes without bidding activity. Korting reserves the right to close early or extend auctions at its discretion.

Payments will be processed through Stripe.

Refund Policy

Due to the nature of liquidation merchandise, returns are accepted only under the following circumstances:

  • Wrong item received
  • Major undisclosed damage that significantly affects functionality or value
  • Item arrives nonfunctional or dead on arrival (unless listed as untested, for parts, or salvage)
  • Missing critical components necessary for basic operation that were not disclosed in the listing
  • Counterfeit items or items materially different from the listing description

The following conditions are not eligible for return or refund:

  • Buyer’s remorse or accidental purchases
  • Minor cosmetic wear, scratches, dents, scuffs, or signs of prior handling
  • Damaged, worn, or missing retail packaging
  • Compatibility issues with buyer equipment, software, or intended use
  • Missing non-essential accessories, manuals, inserts, cables, or packaging materials unless specifically stated in the listing

All return requests must be submitted within 72 hours of delivery and include clear photos and/or video documentation of the issue. We reserve the right to deny returns that do not meet the above criteria.

Sales Tax

All orders are subject to the 6% Michigan sales tax. Tax-exempt buyers must have a current tax-exempt certificate on file before sales tax can be removed from an invoice.

Failure to Pay or Remove Items

Korting reserves the right to charge a 15% non-refundable restocking fee for items not paid for and picked up within seven days of the auction closing. Such items will be considered abandoned and forfeited to Korting. Korting may resell any abandoned or forfeited items.
