CONCEPTRONIC ALTHEA19W45 1-Port 45W GaN USB-C PD Charger with PPS, PD 3.0, 100–240V, White

The Conceptronic ALTHEA19W45 is a single‑port 45W USB‑C charger that uses Gallium Nitride (GaN) technology to provide fast and efficient charging for a wide range of devices. It supports USB Power Delivery (PD) 3.0 and Programmable Power Supply (PPS), offering an output range from 5.0V to 20.0V and compatibility with smartphones, tablets and many laptops. Built‑in protections guard against overload, short circuits and overheating. The charger is designed for indoor use and connects to AC mains with a 100–240 V input range.

Advantages

GaN technology enables a compact design while delivering up to 45W output for faster charging compared with conventional chargers. PD 3.0 and PPS support provide flexible voltage and current profiles for optimized charging efficiency and reduced heat. Integrated safety features protect both the charger and connected devices during normal use.

Suitable for

• Charging smartphones and tablets
• Powering and charging USB‑C laptops that accept up to 45W
• Use at home, office, or while traveling (indoor use)

When it may not be suitable

This single‑port charger delivers a maximum of 45W, so it may not be suitable for larger laptops or devices that require higher wattage for full performance. It is designed for indoor use and requires an AC mains connection within the 100–240 V range.

Key specifications

• Output power: up to 45W
• Port: 1 × USB‑C
• Charging standards: USB Power Delivery (PD) 3.0, Programmable Power Supply (PPS)
• Output voltage range: 5.0 V – 20.0 V
• Input voltage: 100–240 V, 50–60 Hz
• Safety protections: overload, short circuit, overheating
• Colour: white

How to use

Connect the charger to an AC outlet within the 100–240 V range, then plug a compatible USB‑C cable into the charger and the device. The charger will negotiate appropriate voltage and current automatically via PD 3.0/PPS. Monitor device temperature during initial use to confirm expected charging behaviour.

What to consider before purchase

• Maximum output 45W — check your device’s required input power to ensure compatibility
• Single USB‑C port — simultaneous charging of multiple devices is not possible
• Designed for indoor use and requires AC mains power
• Ensure your device supports PD/PPS to take full advantage of fast charging features

Recommendations

Use a high‑quality USB‑C cable rated for PD/PPS and avoid covering the charger during operation to allow heat dissipation. For devices that require more than 45W, choose a higher‑wattage charger.
