What the charger delivers

The Anker Zolo B121E is a 50W wall charger with two USB-C and two USB-A ports. It suits owners of iPhone 16 or 17 series, Samsung Galaxy S23 to S25, Pixel 8 or 9, iPad Air or Pro, and other USB-C devices who want one brick for phone, tablet and accessories. The foldable plug makes it pocket-sized for travel.

Behaviour under sustained load

When all four ports are active the charger maintains 45W total output across the set. With two ports in use the 50W ceiling is available, keeping USB-C1 at 30W and USB-C2 at 20W. Three ports share 45W. The GaN-based ActiveShield 4.0 system monitors temperature continuously during extended sessions.

Limits of the PD 3.0 and QC 3.0 implementation

Single-port peaks are 30W on USB-C1, 20W on USB-C2 and 20W on each USB-A port. The four-port combined ceiling stays at 45W, so a laptop plus three phones will not reach the 50W single-port maximum. Input accepts 100–240V at 50/60Hz with a 1.7A draw.
