Your iphone charger is dual voltage (100–240V) — works in Guinea-Bissau with just a plug adapter.
§ 01 · The verdict
It depends where your device is from.
A device's voltage rating is set when it's manufactured. The country it was built for is the question that decides everything else.

Your iphone charger is dual voltage (100–240V) — works in Guinea-Bissau with just a plug adapter.
§ 02 · The science
What actually happens at the outlet.
The mismatch isn't subtle. Voltage is the pressure pushing electrons through the device — too much, and components fail. Too little, and they don't do their job.
Your iphone charger has a built-in voltage regulator that automatically handles Guinea-Bissau's 230V. It runs the same as at home. The only thing to solve is the plug shape.
How to check your device
Look at the tiny text on your Apple power brick. It will say 'Input: 100-240V~50/60Hz'. Every Apple charger made in the last 15+ years has this rating.
