15 Amp to 20 Amp T Blade Power Adapter, Nema 5-15P to 5-15R/5-20R AC Adapter (1)

Good item, work perfectly and good price

Excellent product and well made. It's being used on a heavy duty vacuum. All of the outlets on this project are on a 20 amp circuit breaker, however the receptacles are the 15 amp style. This adapter solved my problem.

Does the job! Quick delivery, no issues.

I was given two very long power strips but realized the plug was to a 5-20P and needed to convert it to a 5-15P. This adapter worked perfect and now I'm able to use these very heavy duty power strips.

After I bought this one, I found out some lessons learned so I would like to share. There are 2 types of adapters very similar but opposite sides. Therefore there are some reviews mentioning this adapter is reversed. Buyers need to be careful because 1 type is only for 125V and 1 type for 250V (Nema 5 vs Nema 6). If you buy the 4 in 1 adapter, you must be very careful when using it to prevent mix up between 125v and 250V devices.

I used plug for an extension in a in use electrical box. Solved the problem with a wall wort!

Driving a freightliner. In order to plug your truck in you need an adapter or convert this wonky setup to get the result desired. Which is a warm block in winter months. Good price for the product.

Just as advertised. Hard to fine, but apparently, the 20 amp converter connecter, does work just fine into a 15 amp rated wall socket. As I also had confirmed with a few electricians.
