Quick Charge 3.0 Limits

Qualcomm Quick Charge 3.0 negotiates voltage steps up to 18 W and is backward compatible with QC 2.0. Devices without Quick Charge support draw standard USB power instead. The port supplies one connection at a time.

Single Port Constraint

Every charger provides exactly one USB Type-C port. Users who need to charge multiple devices simultaneously from one outlet must use separate adapters or a multi-port alternative.
