Quick Charge 3.0 wall charger, four-pack

This Gigastone GA-8121W set delivers four 18W USB wall adapters with Qualcomm Quick Charge 3.0 certification. Each unit provides a single USB Type-C port and negotiates 3.6V-6V at 3A, 6.5V-9V at 2A, or 9V-12V at 1.5A. The chargers are CE, FCC, RoHS and PSE certified with over-voltage, over-current, over-temperature and short-circuit protection.

Households and teams charging multiple phones

The four-pack suits families, office desks or travel kits where several devices need fast charging at once. It works with iPhone, iPad, Samsung Galaxy S10 through S5, HTC, LG, Nokia, BlackBerry, Motorola, MP3 players and e-readers. Buyers who need USB Power Delivery, multiple ports per adapter or higher wattage for laptops should look at a different product.

Single USB Type-C port with QC 3.0 voltage steps

Each adapter offers one USB Type-C output that steps through the three Quick Charge 3.0 voltage ranges. That single port and the 18W ceiling are the deciding factors — if your device charges faster over USB-PD or needs more than 18W, this charger will not reach its maximum speed.

Questions about this item

Does the 18 W output generate noticeable heat during all-day charging?

The charger includes over-temperature protection and smart IC regulation to manage heat while delivering up to 18 W across its voltage steps.

What cable do I need to use the USB Type-C adapter on each unit?

Each charger has one standard USB port, so a USB-A to USB-C cable is required to connect a USB-C device.

Will these chargers fast-charge my older QC 2.0 phone at its maximum rate?

Yes, Qualcomm Quick Charge 3.0 is backward compatible with QC 2.0, so the phone will charge at its supported QC 2.0 speed.
