FAQ
How many reminders for the Apple Watch and smartphone?
Apple Watch: several reminders (depending on model/use). Smartphone: top-up of a few tens of percent - the keychain format is designed for emergency use, not for recharging to 100%.

Qi 5W works on compatible devices. This is a slow speed, useful for troubleshooting. For faster charging, use wired USB-C .

Yes, this model is USB-C : it plugs directly into iPhone 15/16/17 and most modern Androids.
