A large powerbank with 100w output. Can charge laptop and phone

Absolutely yes. I buy stuff if theres a deal, best to do it before regretting it.

I tend to take pictures of the items i want before the holidays and see if there will be sale.

Bought a Sharge Powerbank for on the go, Gan power adapter to fit 4 usb type Cs. I use an external webcam from logitech, airpods max with 3.5mm cord. Laptop pouch.

External keyboard/mice for when gaming.

Same. I got some deals from Delta Skymiles Shopping portal and got 5 milesper dollar spent if direct from samsung. I stopped trusting Amazon, since there are some reporting fake products.
