Baikelong 2000W high-power LCD digital display screen outdoor power supply is equipped with a 1450Wh large capacity lithium battery for energy storage, with a 2000W inverter output and 100W PD fast charging The battery supports 1000 cell cycle life and high-power solar charging, with a charging power of up to 800W. It comes with a bidirectional inverter function and no need to carry a charger. It can provide power to mobile phones, laptops, some car mounted appliances, card inserted portable routers, and other detector devices at any time.

The application of CX8838B solution is detailed in the disassembly of Baikelong 2000W high-power outdoor power supply.

Baikelong E1500PRO:

• Capacity: 1450Wh (51.8V 28Ah);

• AC output（ × 2) : Total power 2000W, 220V 50/60Hz;

• USB-A output（ × 3）：5V2A； USB-A fast charging output: 5V, 9V, 12V, maximum 18W;

• USB-C output（ × 2) : 5V, 9V, 12V, 20V, maximum 100W;

• 12V output（ × 3) DC 13.6V, maximum 30A;

• AC charging input: 210-230V 50/60Hz, maximum charging 1200W;

• Solar input: 12-18V 100W, 32-95V, maximum 800W

DC charging interface: DC input ports with specifications of 32-95V GX16MF and 12-18V 5521, respectively. It is difficult to avoid various sudden power consumption situations while traveling, and multiple methods can quickly restore power.

USB interface: Equipped with a total of 6 USB interfaces for 2C4A, the C port has output power of 100W and 18W respectively. The A port supports up to 18W fast charging, while the rest are 5V2A, with power identification at the bottom; It can directly power digital products such as smartphones and laptops eliminating the need to carry additional charging cables.

The CX8838B, a 100W synchronous boost/boost output main control chip, has been selected for use in the high-power LCD digital display screen outdoor power supply. The CX8838B chip integrates an H-bridge driver internally, supporting dynamic adjustment of output voltage and current through PWM and analog signals. A single chip achieves synchronous boost/boost voltage conversion, and the chip supports 36V input voltage and 2-32V output.
