LTC MULTI CHARGER LXQC21 is a multi-port wall charger designed for charging smartphones, tablets and other USB-powered devices. The charger supports Quick Charge 3.0 and USB Power Delivery with per-port PD capability up to 20W and combined PD up to 40W depending on port configuration. In addition to PD/QC support, the unit includes two USB-A ports rated at 2.4A each and a total combined output capacity up to 80W, enabling simultaneous charging of multiple devices from a single mains socket. The compact black housing is intended for use at home, in the office or when travelling.

Advantages

The charger combines Quick Charge 3.0 and Power Delivery technologies to provide faster charging for compatible devices while maintaining compatibility with standard USB charging. Two USB-A ports at 2.4A allow connection of legacy devices and accessories. A high total output capacity supports charging several devices at once without requiring multiple adapters. The compact, lightweight design minimises space on a wall outlet and improves portability for travel.

How to use

Plug the charger into a standard mains outlet and connect devices using suitable USB-A or USB-C cables. The charger automatically negotiates the optimal protocol (QC 3.0 or PD) with compatible devices; non-compatible devices will draw standard USB current. When charging multiple devices, distribution of power will follow the charger's internal allocation and the combined output limit. Avoid using damaged cables and ensure the connected device supports the desired fast-charge protocol for maximum performance.

Usage recommendations

For best results, use high-quality cables that match the required current and protocol (USB-C for PD, compatible USB-A cables for other devices). Monitor device temperature during fast charging and avoid covering the charger while in use to maintain adequate ventilation. Do not exceed the total output capacity when connecting multiple high-power devices.
