Conceptronic ALTHEA19W33 2-Port 33W GaN USB PD Charger, USB-C x 1, USB-A x 1, QC 3.0, PPS, PD 3.0

The Conceptronic ALTHEA19W33 is a compact 2-port 33W GaN charger designed for indoor use. It combines one USB-C port with USB Power Delivery (PD) 3.0 and one USB-A port with Quick Charge (QC) 3.0 to charge phones, tablets and other portable devices. The charger supports output voltages from 3.3 V to 20.0 V and a maximum total power of 33 W, with built-in protections against overheating, overload and short circuiting.

Advantages

GaN technology enables smaller size and improved efficiency compared with traditional silicon chargers, providing fast charging while reducing heat generation. The dual-port layout allows simultaneous charging of two devices with different protocols (PD and QC). Universal input (100–240 V AC) ensures compatibility with global mains voltages, and integrated safety features protect connected devices.

Suitable for

• Charging smartphones and tablets
• Powering small USB-C laptops and ultrabooks that accept up to 20 V
• Charging accessories such as earbuds, power banks and wireless mice
• Travel and home use where a compact, two-device charger is needed

When charging multiple devices, the charger distributes up to 33 W total across both ports according to device requirements. Ensure cables and device ports are free of debris and firmly connected before use.

Recommendations

Use high-quality, manufacturer-recommended USB cables to ensure safe and efficient charging. Avoid exposure to extreme temperatures, and do not use the charger if it is physically damaged. For devices requiring higher wattage, verify device charging specifications to confirm compatibility with the charger's maximum 33 W output and supported voltage range.
