There is greater resistance with longer cables. There is less resistance in a shorter cable. Your phone will therefore charge far more slowly with a 6-foot wire than it would with a 3-foot one. Your adapter is discharging X watts, but the resistance of the cable is causing only Y watts to reach the end.
A: Even with a high amp charger, inexpensive, long, and thin wires charge noticeably more slowly.
In addition, you can select high-quality extension cables according to other requirements. Please be aware that using a different charging cable to lengthen an EV charging cord is not recommended. It might result in an unreliable connection. To extend your charger, always use a cord made for the sort of socket you are using.
There are differences amongst EV charging cords and they are not all the same. The side that is plugged into the chargepoint socket should always be a Type 2 connector, with a connector on either end. A Type 1 or Type 2 connector is connected to the opposite end that plugs into the car socket.
EVs with large capacities work best with type 2 charging cables. For EVs having charging outlets on one side of their body, it's a good idea to use a longer charging cable so that they can easily reach the charging station.
The 6mm twin and earth cable's current carrying capacity is displayed in the table below. The 40A AMP home cooking and shower circuits are the primary applications for this cable.
25 ampsBecause it has a current rating of 13.5 amps, but can handle up to 25 amps, it is advised that you use a 2.5 mm square wire for such circuits. A wire can still carry more current than its rated ampacity, as you've seen, but overloading it is dangerous.

Information about Power Cables and Electric Shower Power RatingsAs long as the shower unit is within 18 meters of the fuseboard, showers up to 9kw are permitted to use a 6mm cable. The recommended rating for fuses and switches is 40 amps. Units located within 35 meters of the fuseboard should have a 10mm cable for showers up to 12.5 kW.
Should you be fortunate enough to have sufficient length, a portion of that small circuit will need to be rewired. Depending on the run, 6mm cable should work just fine for an 8.5kW shower. While RCDD protection has its benefits, bonding and cross-bonding are significantly more crucial.
