Oplader QOLTEC 51828 140W GaN 3×USB‑C PD + 1×USB‑A QC 3.0 – multiport-snellader

The QOLTEC 51828 140W GaN multiport fast charger delivers consolidated power for laptops, tablets, smartphones and other USB devices. Featuring three USB‑C ports with Power Delivery and one USB‑A port with Quick Charge 3.0, this charger can distribute up to 140W total across connected devices. The GaN (gallium nitride) design allows a smaller, lighter housing and improved thermal efficiency compared with conventional silicon chargers, making the unit suitable for travel and everyday desktop use.

Advantages

This multiport charger supports simultaneous charging of multiple devices while dynamically allocating power to match device requirements, reducing the need for multiple adapters. The GaN technology reduces size and heat generation without sacrificing output, and the inclusion of a Quick Charge 3.0 USB‑A port ensures compatibility with older fast‑charging devices. Built‑in safety protections guard against overcurrent, overvoltage and overheating to preserve connected devices and the charger itself.

Suitable for

• Charging laptops and ultrabooks that accept USB‑C Power Delivery
• Powering tablets and large‑screen devices during work or travel
• Fast charging smartphones and accessories simultaneously
• Replacing multiple chargers in a compact travel kit

Key specifications

• Total maximum output: 140W distributed across all ports
• Ports: three USB‑C (Power Delivery) and one USB‑A (Quick Charge 3.0)
• GaN semiconductor design for reduced size and improved thermal performance
• Dynamic power distribution to allocate appropriate wattage per connected device
• Input: mains AC (region-dependent) with integrated or detachable power cord as applicable
• Built‑in protections: overcurrent, overvoltage, short‑circuit and thermal protection

How to use

Connect the charger to a suitable AC outlet using the provided cable or integrated plug. Plug devices into the USB‑C or USB‑A ports using appropriate cables rated for data and power delivery; the charger will automatically negotiate the correct voltage and current via Power Delivery or Quick Charge protocols. For laptops or high‑power devices, connect directly to a USB‑C PD port and verify the device is receiving sufficient wattage. Avoid using damaged cables and disconnect devices once charging is complete.

Recommendations

Place the charger on a flat, stable surface with adequate ventilation and avoid covering it while in operation. Use quality USB‑C and USB‑A cables that match the power requirements of your devices. If charging multiple high‑power devices at once, be aware the total available power is shared between ports; prioritize devices that require higher wattage when necessary. Unplug the charger from the mains if it will not be used for extended periods.
