• ADVANCED SOLID-STATE TECHNOLOGY Solid-state technology (SST) is the evolution in lithium batteries, which provide safer, more compact, and lighter power output than their conventional lithium-ion or LiFePO4 counterparts. The new solid-state battery provides safer and more compact power for off-grid and recreation use.
• SAFETY FIRST - Yoshino solid-state battery cells provide a peace of mind that the competition leaves out; Yoshino has full ETL certification on all its portable power stations and has been tested by Energy Assurance Labs (accredited third-party lab in the United States) undergoing nail penetration tests along with thermal runaway tests (no flammability issues like traditional lithium batteries), over voltage, over current, over charging, over discharging and short circuit protection.
• AWARD-WINNING COMPACT DESIGN - A single solid-state cell holds more than double the capacity of a LiFePO4 battery cell. This maximizes power efficiency in a smaller, lighter, compact unit. Why lug heavy equipment, with Yoshino you don't have to.
• ULTIMATE POWER SECURITY - 4,000 watts continuous (6,000 peak watts) power and a capacity of 5,173Wh provide power for many devices and most home appliances. This SST battery is rated to 4,000 cycles to 80% (11+ years, 7 days of everyday use.) Lasting you roughly 2 days of power for a full-sized refrigerator, lights, and mobile devices - you can scale it up by adding more 2,562Wh capacity expansion batteries!
• FLEXIBLE POWER STORAGE - 48V DC output is available for use when running the expansion battery independently, an adapter is included.
• EXPANDABLE WITH SMART LINK - Smart Link allows the ability to connect additional 2,562Wh expansion batteries together to increase capacity. With integrated Infinity Connect technology, you can link up to 15 expansion batteries, allowing the ability to match just about any capacity needs of up to 41kWh.
• POWER ON THE GO - Truly Portable at 53.6 lbs. (B4000 SST) and 48.5 lbs. (EXB1) this power station expansion bundle is great for camping, emergencies, or RV travels. Features UPS (Uninterruptible Power Supply) backup with two 15W wireless charging pads, app for remote access via Wi-Fi or Bluetooth.
• MULTIPLE WAYS TO RECHARGE - The B4000 SST can be recharged using AC fast charging (0-100% within 90 minutes), and optional solar charging (5.5 hours - with 600W of solar directly in the B4000). The EXB1 can be recharged using AC fast charging (0-100% within 90 minutes when connected to the B4000) and optional solar charging (1200W, 3 hours).
• HIGHER SOLAR INPUT - The expansion battery can accept up to 1200W of solar input for faster recharging when off-grid, camping, or in emergencies. Quiet, emission-free, and reliable.
• SUPPORTS 11 CONNECTIONS - Ports include AC (pure sine wave, 120V x2, 120V/30A RV x1), DC (12V) x2, USB-A x2, USB-Type C (20W) x1, Type C PD (100W) x1, Wireless Charging Pad (15W) x2
