Akyga power adapter AK-CH-25 USB-A + 3× USB-C PD 5–28V max 5A 140W Quick Charge 3.0 GaN

The Akyga AK-CH-25 is a compact multi-port power adapter designed to charge multiple USB devices simultaneously. It combines one USB-A port with three USB-C Power Delivery outputs that support voltages from 5 to 28 V and up to 5 A per port, delivering a combined maximum output of 140 W. Built with GaN technology and Quick Charge 3.0 compatibility, the adapter is intended for efficient, high-power charging of smartphones, tablets, laptops and other USB-powered equipment in home, office or travel environments.

Advantages

Small form factor and GaN components reduce size and heat generation while maintaining high power output. The combination of USB-C Power Delivery and Quick Charge 3.0 ensures wide device compatibility and faster charge times for supported devices. Multiple outputs allow simultaneous charging of several devices with intelligent power distribution up to a total of 140 W. The adapter is suitable for situations where space and weight are limited, such as business trips or everyday desk use.

Suitable for

• Charging smartphones and feature phones
• Powering tablets and e-readers
• Charging laptops and ultrabooks that accept USB-C PD
• Powering accessories such as wireless earphones, smartwatches and portable battery packs

Key specifications

• Ports: 1× USB-A (Quick Charge 3.0), 3× USB-C (Power Delivery)
• Output voltage range: 5–28 V
• Maximum current per port: up to 5 A (depending on device and PD negotiation)
• Total maximum output power: up to 140 W
• Technology: GaN (gallium nitride) for higher efficiency and reduced size
• Simultaneous charging: multiple devices with automatic power distribution

How to use

Connect the adapter to a mains outlet using the integrated or supplied power cable as delivered in the product package. Plug the device charging cable into the appropriate USB-C or USB-A output. Devices that support Power Delivery or Quick Charge will negotiate the correct voltage and current automatically. Monitor device temperature during the first usage; if a device becomes unusually warm, disconnect and allow it to cool before resuming charging. Always use cables rated for the required power level for high-wattage charging.

Usage recommendations

Use high-quality USB-C cables that support Power Delivery for laptop charging and cables rated for high current when delivering close to the adapter's maximum output. Do not cover the adapter while charging for extended periods to ensure adequate heat dissipation. For travel, confirm local mains voltage compatibility and use appropriate plug adapters if needed.
