Input voltage range
The input voltage range of this charging board is AC 100V~240V, supporting global standard grid voltage, suitable for a variety of voltage environments, especially suitable for international travel or global operation of equipment. The input frequency is 50/60Hz to ensure normal use in different regions.
Output voltage and current
The charging board provides two USB ports with an output voltage of 5V DC, which is the standard voltage commonly used by USB devices. The maximum output current of each USB port is 2.1A, which can provide sufficient charging current for most smartphones, tablets and other USB devices. Overall, the output power of the charging board is 10.5W, which is enough to meet the daily charging needs of ordinary devices.
Does it support fast charging?
Although this model of charging board provides a standard 5V output voltage and 2.1A current, it does not specifically indicate that it supports fast charging protocols such as Quick Charge (QC) or USB Power Delivery (USB PD). Therefore, although it can provide reliable charging speeds for most devices, if your device supports fast charging, the charging speed may not be at the highest efficiency. If a higher charging speed is required, it is recommended to choose a charger that supports the fast charging protocol.
Compatibility
The HJXY-1818 charging board is compatible with most USB devices, including smartphones, tablets, Bluetooth headsets, e-book readers, etc. Due to its standard USB output interface, it is able to serve all devices that support USB charging. For devices that do not support the fast charging protocol, the charging board can still provide regular charging speeds; for devices that support fast charging, the charging board will charge them at their maximum capacity.
Multiple protection functions
This charging board has built-in multiple protection functions to ensure the safety of the charging process. Including:
Overvoltage protection: prevents damage to the device due to excessive voltage.
Short circuit protection: avoids damage to the device due to a short circuit in the circuit.
Overload protection: prevents damage to the device when the load range is exceeded.
Temperature protection: automatically disconnects when the operating temperature is too high to prevent safety issues caused by overheating of the device.
Working environment and size
Working temperature range: -20℃ to +50℃, ensuring normal operation in different temperature environments.
Storage temperature range: -20℃ to +80℃, adapting to a wide range of storage environments.
Humidity range: 10%～90% RH, adapting to a variety of humidity conditions.
Application
This charging board is widely used in homes, offices and other scenarios where multiple devices need to be charged simultaneously. It can be installed in furniture sockets, power strips, or used as part of 3C products, providing a convenient USB charging port. Suitable for daily home use, commercial office environments and charging needs of some electronic products.
HJXY-1818 AC/DC 2 USB charging board is an efficient and safe device that can convert AC power to 5V DC, supports charging of two USB ports at the same time, and is suitable for most USB devices. Its multiple protection functions, wide operating temperature range and high working efficiency (≥79%) make it an ideal charging solution for home, office and commercial environments. Although it does not support fast charging, it can meet the charging needs of general electronic devices and is a reliable and easy-to-use charging pad.
