A power supply, the thing that gets plugged into AC mains power and outputs some sort of DC (usually USB now) to power electronics is not a “charger”. It (usually) doesn’t know anything about charging batteries, and connecting its output directly to a Li-ion battery would lead to an explosion. The charger is integrated into the device receiving that power.
“Portable battery” is a terrible term to describe a USB powerbank. Thousands of battery types are portable, but don’t have USB ports or output exactly the right voltage. Some powerbanks are sold without batteries.
My kid calls USB cables “chargers”. My sister witnessed this for the first time, turned to me (known techie and pedant) and was like “You’re okay with this?”
