Chargers have the wattage ratings printed directly on them. And the rating will simply be the maximum that the charger can provide. Wattage is pulled, not pushed. So if you plug your phone into an oversized charger, the phone will only draw what it needs.
Just grab the highest wattage you see, and the phone will pull what it needs.
Caveat that this only applies to USB chargers. If you find some random non-USB, old-school type charger (like the ones with the round connectors) that fits your device, don’t plug it in until you’re sure that the voltage and polarity are correct.
