Features + Benefits

  • 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 U.S. lab tested against thermal runaway (no flammability issues like traditional lithium batteries), along with 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.
  • POWER AND CAPACITY – 4,000 watts continuous (6,000 peak watts) power and a capacity of 2,611Wh provdes power for devices and most all home appliances. This SST battery is rated to 4,000 cycles to 80% (11+ years, 7 days of everyday use.)
  • 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 16 expansion batteries, allowing the ability to match just about any capacity needs of up to 40kWh.
  • POWER ON THE GO – Truly Portable at 53.6 lbs. this power station is great for camping, emergencies, or overlanding adventures. Features UPS (Uninterruptible Power Supply) backup with two 15W wireless charging pads, app for remote access via Wi-Fi or Bluetooth. Quiet, emission-free, and reliable. Stay connected on the go.
