GaN Chargers. In the past several years, you have probably seen more ads for battery powered device chargers that claim they are the smallest, lightest and longest lasting batteries. In fact, the new Gallium Nitride chargers produce less heat. Less heat means components can be closer together, so a charger can be smaller than ever before—while maintaining all the power capabilities and safety standards. Notebook computers require 45 Watts or more of power to charge quickly. GaN tiny chargers that produce 65 Watts are available for less than $50, and some have extra USB-A and USB-C ports since there is always power to spare with these new chargers. I bought several to keep in the office, house, and RV. Just plug in the computer wherever I happen to be. Don't carry around bulky chargers anymore. Trust the science.
