Reasonable question.
The answer is actually fairly simple, the important part is 5v as voltage needs hardware to be changed (step down/up converters). So charger provides 5v, phone needs 5v all is good for device safety. Amps can be thought of as the flow rate and is controlled by the phone and charger in concert. Rest assured as long as the voltage is 5v the phone will be fine.
If any of you have a fast charging device you can see it in action. When you first plug it in It says charging, after a bit it says fast charging because a higher amperage is negotiated.
Here are a few examples:
- 5v3a charger > device that needs 5v1a is fine the charger will only provide 5v1a
- 5v1a charger > device that wants 5v3a is still fine, the device will only charge at 5v1a (slower than it could charge)
USB is standard at 5v so no issues should be present with any plug.
Not sure if the pinephone has something like pumpexpress (fast charging), if so you want your wallwart to provide those amps to take advantage of the fast charging, but again no safety issues if it doesn't.
Someone asked about a multivoltage charger. It will be safe since it can provide 5v, HOWEVER the one mentioned is QC which is proprietary and not compatible with PD standards so it won't provide a fast charge.
