Four-Pack Wall Charger

The Gigastone GA-8121W is a set of four USB wall chargers finished in black. Each unit delivers up to 18 W through a single USB Type-C port. The kit suits households or small offices needing several identical fast-charge adapters.

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.
