Conceptronic ALTHEA20B45 45W GaN USB-C PD & USB-A QC 3.0 kaksiporttinen seinälaturi musta

The Conceptronic ALTHEA20B45 is a compact 45W GaN (Gallium Nitride) dual-port wall charger designed to power smartphones, tablets, laptops, and other USB-charged devices from a single plug point. Using GaN semiconductor technology, it achieves a significantly smaller footprint than conventional silicon-based adapters without sacrificing output power or safety.

Advantages

The USB-C port supports USB Power Delivery up to 45W with PPS (Programmable Power Supply), enabling adaptive voltage and current delivery for compatible devices. The USB-A port delivers up to 18W via Qualcomm Quick Charge 3.0, keeping smartphones topped up rapidly. The wide 100–240V AC input makes this charger compatible with mains sockets across the world, ideal for frequent travellers. Built-in protection against overload, overheating, and short circuits ensures both the charger and connected devices remain safe during operation.

Suitable for

• Charging USB-C laptops and MacBooks at up to 45W
• Fast-charging Android smartphones and iPhones simultaneously
• Travel use with universal 100–240V AC input

How to use

Plug the ALTHEA20B45 into any standard wall outlet (100–240V AC). Connect your USB-C device for up to 45W Power Delivery charging, or your USB-A device for up to 18W Quick Charge 3.0. Both ports can be used simultaneously; the charger automatically negotiates the optimal voltage and current for each connected device via PD/PPS and QC 3.0 protocols.

Recommendations

For best results, use certified USB-C cables rated for the required wattage. When charging a laptop, prioritise the USB-C port; connect a smartphone to the USB-A port to maximise throughput on both ports at once. Keep the charger in a ventilated area during extended charging sessions.
