Setting the bar for professional power stations. The B4000 doesn’t just deliver extremely high output, it does so with a class-leading power-to-weight ratio. Thanks to solid-state technology, it provides more power per pound than any other power station—and it’s safer, too. With 4,000 watts on tap, it’s perfect for home backup and even includes a 30-amp RV outlet for recreational use. And despite its capacity, it can charge from 0-80% in just over an hour.
- 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 provides 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.)
- LIMITLESS SOLAR - Yoshino portable solar panels feature market leading solar technology, mono-crystalline silicon solar cells with a 23% efficiency rating allowing for even more energy conversion from the sun. These panels are also expandable, you can buy multiple panels and link them to expand the overall energy capacity.
- POWER WITHOUT BOUNDARIES – Whether you are out camping, on an adventure, or in the middle of an emergency, this portable solar generator weighs 53.6 lbs. and provides a great source of power when all else fails. Featuring built-in aluminum handles for easy transport, and 3 compact solar panels that weigh 18.7 pounds and measure 31” x 72” x 0.2” each, unfolded.
- CLEAN, GREEN, ENERGY –Yoshino solid-state portable solar generators provide clean and natural energy by harnessing the sun's power. Perfect for using on outdoor or off-grid adventures. Quiet with zero gas emissions and harmful fumes, keeping you connected, always.SUPPORTS 11
