USB ports are widely availabe and many phones come with their own wall chargers. They offer a steady voltage and current level and are designed specifically for charging devices like phones.

If you’re looking for more flexibility, thre are also portable battery packs that can be used to charge your device on the go. These battery packs come in various capacities so you can always have a backup source of power when you need it most.
