Most listings show a mix of USB-C and USB-A ports. Configurations range from a single USB-C plus two USB-A ports to dual-port USB-C/USB-A designs, allowing you to charge two or three devices depending on the model.

Listings use standard fast-charge labels such as Power Delivery (PD) and Quick Charge (QC), including references to QC 3.0 and PD on dual-port and higher-wattage adapters.

Some chargers provide three USB ports and can power up to three devices simultaneously, while many dual-port chargers offer two ports for charging two devices at the same time.

Several listings note ETL safety certification and list built-in protections such as overheat protection, short-circuit protection, over-voltage and over-current protection; others also mention overcharge protection.
