Which Anker product has been the most useful in your daily setup?

I’m looking at a few Anker products to simplify my everyday charging setup, especially a multi-port GaN charger, a power bank and a USB-C hub.
For me, the most important things are charging stability, heat control, portability and long-term reliability. Higher wattage sounds useful, but I’m not sure whether it’s worth paying extra if I’m mainly charging a phone, headphones and occasionally a laptop.
Which Anker product do you use most often? Has it remained reliable after several months, and is there anything you wish you had known before buying it?
I’d appreciate honest recommendations as well as any drawbacks you’ve noticed.
