GaN ULTRA 35W charger QOLTEC — 1x USB-C PD 5–20V 2.25–3A, 1x USB QC 3.0, white

QOLTEC GaN ULTRA 35W is a compact mains charger that uses Gallium Nitride (GaN) technology to deliver efficient fast charging in a small white housing. It features one USB-C Power Delivery (PD) output with adjustable voltage range for PD-enabled devices and one USB-A port with Quick Charge 3.0 compatibility for devices that support QC protocols. The charger is intended for everyday use with smartphones, tablets and other portable electronics that accept PD or Quick Charge, offering a balance of power and portability.

Advantages

The GaN ULTRA 35W charger combines a reduced physical footprint with high conversion efficiency thanks to GaN components, which generate less heat than traditional silicon chargers. The USB-C PD output supports a range of voltages to match device charging requirements while the USB QC 3.0 port provides backward-compatible fast charging for many existing devices. Its white, minimalist design is suitable for home, office and travel use.

Suitable for

• Fast charging PD-capable smartphones and tablets
• Charging small laptops and ultrabooks that accept USB-C PD within the supported power range
• Powering accessories such as wireless earbuds, power banks and portable speakers
• Use at home, in the office or while travelling where compact chargers are preferred

Key specifications

• Total maximum output: 35 W
• USB-C (Power Delivery): adjustable output 5–20 V, current range 2.25–3 A
• USB-A (Quick Charge 3.0): compatible with QC 3.0 fast-charging protocols
• GaN (Gallium Nitride) power-stage technology for improved efficiency and reduced size
• Colour: white; compact mains plug form factor

How to use

Connect the charger to a mains outlet, then plug a compatible USB-C cable into the USB-C PD port or a USB-A cable into the QC 3.0 port. The charger will negotiate the appropriate voltage and current with PD- or QC-enabled devices automatically. For best performance, use the device’s original cable or a certified cable rated for the required current and PD/QC standards. Avoid covering the charger during operation to allow heat dissipation.

Usage recommendations

To maintain optimal charging performance and safety, match the charger’s outputs to device specifications: use the USB-C PD port for devices requiring PD negotiation and the USB-A QC 3.0 port for Quick Charge-compatible devices. Use certified cables and avoid subjecting the charger to moisture, extreme temperatures or impact. If charging a small laptop, ensure the device accepts the charger’s maximum output within its supported PD voltage and current range.
