A charging kit that actually fits in a bag

A 30W or 45W USB-C brick covers a phone and still helps a tablet. Two ports matter more than a huge watt number if you travel with earbuds. Folding prongs keep the brick from tearing a sleeve.

Carry one short cable for the power bank and one longer cable for the hotel desk. Braided nylon lasts longer in a bag than the soft white cable that came with an old phone.

A 10,000mAh bank is the sweet spot for a day away from an outlet. 20,000mAh is for weekends and flights. Magnetic banks are convenient on a magnetic case and annoying if the case is not magnetic, so check the product page before you add one.

Wireless pads are a desk tool, not a travel tool. They are slower and they need a flat spot. Use the cable when you are in a hurry.
