Seinänturi OTTERBOX 78-81343 100W GaN 2× USB-C ja 2× USB-A liitännöillä

The OTTERBOX 78-81343 100W GaN wall charger is a multi-port power adapter designed to charge laptops, tablets, smartphones and other USB devices. Featuring two USB-C ports and two USB-A ports, the charger delivers up to 100 watts of total power with GaN (gallium nitride) technology that enables a smaller, cooler adapter compared with traditional silicon designs. Its compact footprint and intelligent power distribution allow several devices to be charged simultaneously while maintaining safe voltage and current levels.

Advantages

This wall charger combines high total output and efficient GaN components to reduce size and heat generation. Dual USB-C ports provide fast charging for compatible laptops and tablets, while two USB-A ports support a wide range of legacy and current devices. Built-in circuitry manages power allocation across all ports to optimize charging speed and protect connected devices from overcurrent, overvoltage and short-circuit events. The compact design and foldable plug option make it convenient for travel and everyday use.

Suitable for

• Charging USB-C laptops and ultrabooks that accept up to 100W input.
• Powering tablets and large-screen smartphones during heavy use or fast charge sessions.
• Simultaneous charging of multiple devices such as phone, tablet, wireless earbuds and power bank.
• Home, office and travel use where a compact, high-output charger is needed.

Key specifications

• Form factor: compact wall-mounted adapter suitable for travel and desk use.

How to use

Plug the charger into a compatible wall outlet. Connect devices using the appropriate USB-C or USB-A charging cables. The charger will automatically allocate power among connected devices based on their power requirements. For fastest laptop or tablet charging, connect to a USB-C port and use a cable rated for the device’s input power. Avoid blocking ventilation around the adapter during extended high-power use.

Recommendations

Use high-quality, certified USB-C cables for high-wattage charging and connect only devices within supported voltage and current ranges. Disconnect the charger from the outlet when not in use for extended periods and keep it away from liquids and extreme temperatures.
