I have an original power adapter for my phone that only has an 18-watt maximum output. Recently, I bought a new charging cable that can support up to 65 watts. However, when I tried using it, the fast charging didn't work as I expected. I thought the cable's higher wattage rating would help, but customer service mentioned that the fast charging won't work because my adapter is limited to 18 watts. Can someone explain why this is the case?

When it comes to fast charging, you need to define what fast charging means for your device. Your phone will only charge at 18 watts because that's all your charger can output. If your phone is designed for higher charging rates, then it may have a different standard for what fast charging means.
It's a bit intricate, but here's the deal: your phone, the cable, and the charger each have their own wattage limits. The maximum wattage that can be transferred is determined by the lowest of these three. So, while your cable can technically handle 65 watts, it won't mean anything if your charger only provides 18 watts. To really utilize that cable, you'd need a charger that can output at least 65 watts. Also, check your phone’s specifications to see the maximum wattage it can handle, since using a much more powerful charger than your phone can accept won't help either.
You won't get 65 watts from an 18-watt charger. If your phone can take a higher charge, definitely invest in a compatible 65-watt charger. Just make sure to stick to reputable brands because cheap knockoffs can be risky; I personally trust Anker products.
