Description

The BLUETTI Apex 300 Versatile Portable Power Station + 2x B300K Expansion Batteries is a high-capacity, modular energy storage system that provides reliable power for home backup, off-grid living, motorhomes, outdoor adventures, and emergency preparedness. Combining the powerful BLUETTI Apex 300 with two B300K expansion batteries gives you a massive 8,294.4Wh of total energy storage capacity, allowing you to run essential appliances, electronics and power-hungry devices for extended periods.

Built with a second-generation automotive-grade LiFePO4 battery, the BLUETTI Apex 300 is engineered for longevity, offering a lifespan of up to 17 years under normal use. Its plug-and-play design ensures quick setup, while UPS functionality with a ~20ms switchover helps keep critical devices running during power interruptions. Whether you're preparing for outages or optimising your energy usage, it delivers dependable, uninterrupted power.

For renewable energy users, the system offers impressive solar compatibility. With support for high-capacity solar input via SolarX technology, it can be integrated into existing solar setups, making it a powerful tool for reducing electricity costs and increasing energy independence. Combined with high-capacity generator compatibility, it ensures continuous power availability even in prolonged outages.

B300K Expansion Batteries:

BLUETTI B300K Expansion Batteries are high-capacity energy storage modules designed to seamlessly expand the power capacity of compatible BLUETTI portable power stations, including the Apex 300. Featuring a substantial battery capacity of 2,764.8Wh per unit, the B300K significantly extends runtime for appliances, tools, electronics and essential home devices, making it ideal for backup power, off-grid living and outdoor use.

Built around an automotive-grade LiFePO₄ battery, the B300K delivers exceptional durability, safety and long-term performance. With an impressive lifespan of over 4000 charge cycles to 80% original capacity, it is engineered to provide years of reliable energy storage while maintaining excellent battery health. Combined with BLUETTI's advanced AI-powered Battery Management System (AI-BMS), robust aluminium casing and efficient cooling technology, the B300K is designed to perform in demanding environments while protecting your investment.
