AirPods charging times vary by model and whether you are charging the earbuds themselves or the charging case. Charging AirPods earbuds:

• 1st and 2nd generation AirPods take about 25 minutes to fully charge from zero.
• 3rd generation AirPods and AirPods Pro take about 1 hour to fully charge.
• AirPods Max, which charge directly and not via a case, take roughly 2 hours to fully charge.
• A quick 5-minute charge typically provides about 1 hour of listening or talk time across most AirPods models.
• For 1st and 2nd generation AirPods, a 15-minute charge can give around 3 hours of listening time

Charging the AirPods case:

• The charging case usually takes about 1 hour to fully charge when using a wired connection.
• Wireless charging of the case takes about 30 minutes longer, totaling roughly 1.5 hours.
• The case can recharge the AirPods multiple times (up to 4 full charges).
• Newer AirPods Pro 2 cases use USB-C instead of Lightning for charging

Summary:

• AirPods earbuds: 25 minutes (older models) to 1 hour (newer models) for full charge.
• Quick charge: 5 minutes for about 1 hour of use.
• Charging case: about 1 hour wired, 1.5 hours wireless.

This means you can get a useful amount of charge quickly, but full charging takes around an hour for most AirPods models and their cases
