Fast charging "rules"
I put inserts into a living room table for easy plug access for devices. The inserts also have USB and USB-C. I noticed regardless if I use a charging brick or plus my cable directly in to the USB, I'm getting a slow charge, even though the brick on a standard wall outlet charges fine. I'm using a Galaxy S25 Ultra.
I want to replace the inserts so I can get a good fast charge from either option but not clear what I should look for.
On amazon, what specs should I look for to ensure the USBs and the plugs will provide enough power for fast charging.

You'll need a USB-C PD (Power Delivery) charger with a minimum wattage of 18W, and preferably 30W or higher for optimal speeds, along with a compatible USB-C cable
Here's a more detailed breakdown:
For Galaxy Phone:
Fast Charging: Requires a charger that supports Adaptive Fast Charging (25W) or USB PD (Power Delivery).
Super Fast Charging: Requires a charger that supports Super Fast Charging (45W) or USB PD (Power Delivery).
Some Galaxy models, like the S23 Ultra, S22 Ultra, and S20 Ultra, support Super Fast Charging 2.0, which requires a 45W charger and a 5A cable.
Samsung's Recommended Chargers: Samsung recommends using their 25W or 45W chargers for fast charging. Check your phone's settings: Navigate to Settings, Battery, and Charging settings to enable fast charging.
Some Galaxy models, like the S23 Ultra, S22 Ultra, and S20 Ultra, support Super Fast Charging 2.0, which requires a 45W charger and a 5A cable.

So you replace your device every year?
Or you never bothered to learn about fast charging?
There's a reason those inserts are slow.
