It is also not intended as a replacement for specialized chargers for laptops or high-wattage devices that require higher voltage/current profiles.
Key specifications
- Number of USB ports: 3 × USB-A
- Maximum current per port: up to 3 A
- Intended use: mains-powered wall charger for USB devices
- Protection: basic overload/current protection
- Form factor: compact wall-mounted charger
How to use
Plug the charger into a standard mains outlet and connect devices using their USB-A to device charging cables. Ensure each device’s cable is fitted securely into a USB-A port. Charging will begin automatically when a compatible device is connected. To avoid overheating, do not cover the charger while in use and disconnect devices when fully charged. Use the charger in environments that match your local mains voltage and safety standards.
What to consider before purchase
- Check whether your device requires USB-C Power Delivery or a proprietary fast-charge protocol for optimal charging speed.
- Confirm that USB-A connectors and your existing charging cables are compatible with your devices.
- Consider total simultaneous current needs if you plan to charge multiple high‑draw devices at the same time.
Usage recommendations
For typical phone and accessory charging, use one cable per device and avoid daisy-chaining additional adapters. If a device supports higher-power fast charging via USB-C, use a matching charger to achieve the fastest charging rates. Regularly inspect cables for damage and replace any frayed or faulty cords to maintain safe charging.
