AKJIA is a manufacturer of power cord for more than 14 years in China. and got many UL listed products for USA. Strictly according to the UL requirement, all standard materials are taken for every piece of products and all the tests are accomplished before delivery.
This product has a Type-B plug (NEMA 5-15P) to a NEMA 5-15/20R (T-slot). It is rated for 125 volts and a full 15 amperes. How much is 15 amperes and 125 Volts? By technicality it's 1,875 Watts, but let's just say that's more than enough to run some standard household appliances like a microwave, blender, or even your television.
We take a much thicker 12 AWG wire instead of 14 AWG, which allows the product to handle the full 15-Amps without getting warm up. It is much safer when in indoor use. The female end accepts NEMA 1-15P, 5-20P and 5-15P Plug Types. Thus it can be used widely.
