Delivering an impressive 4,000W of Pure Sine Wave AC output power with a 2,611Wh capacity, the B4000 SST redefines portable energy solutions for IT professionals, businesses, and recreational users alike. Designed for optimal performance, its Pure Sine Wave output ensures clean, stable power with low Total Harmonic Distortion (THD), making it safe for sensitive electronics, IT equipment, and high-precision devices.

The B4000 SST is equipped with UPS (Uninterruptible Power Supply) mode, ensuring seamless emergency power during outages and protecting critical systems such as routers, servers, and refrigerators from downtime. Due to the larger battery capacity this unit will offer extended runtime on your devices compared to traditional UPS systems that are much smaller. A robust Battery Management System (BMS) adds an extra layer of security, protecting the unit from over-voltage, over-current, short circuits, and thermal irregularities, ensuring long-lasting, reliable performance. Additionally, GaN (Gallium Nitride) technology enhances battery efficiency, optimizing energy transfer and reducing heat generation for improved performance and longevity.

This power station features two fixed 15-watt wireless charging pads, compatible with devices like the iPhone 16 Pro, Galaxy S25, and other smart devices, allowing simultaneous charging while powering additional electronics or tools. Its versatile control panel offers 9 ports (AC, DC, RV, USB-A, and USB-C) USB-C PD is perfect for charging tablets and laptops efficiently and quickly. It has 2 wireless charging pads and 9 ports, which gives you 11 total connection options, making it ideal for powering a wide range of devices and workstation setups like computers, monitors, and printers. It can also be used recreationally for activities such as camping and small events, or as emergency power for homes and off-grid living.

The B4000 SST integrates advanced solid-state technology with optional Wi-Fi and Bluetooth-enabled app control for remote monitoring and configuration. A bright LED light adds convenience in low-light or nighttime scenarios. The Smart Link feature allows capacity expansion, supporting up to 16 additional battery modules for an impressive 10-40kWh capacity, making it perfect for extended off-grid use or high-demand applications.

Recharging is efficient and versatile: 0-100% in just 90 minutes via AC power, 5.5 hours with optional fast solar charging, and 22 hours via car charging. Completely silent, with zero gas emissions and harmful fumes, the B4000 SST is an environmentally friendly and reliable power solution. Whether supporting critical IT systems, providing emergency backup, or enabling off-grid independence, this lightweight, portable, and powerful unit ensures your devices stay powered and protected in any scenario.
