Description
Weighing only 53.6 lbs. and delivering 4,000W AC output and 2,611Wh capacity, the Yoshino B4000 SST Solid-State Portable Power Station provides truly portable power wherever your adventure takes you. This sustainable, battery-powered backup system is made for outdoor use, home backup, power tools, and off-grid living, and it’s quiet, with zero gas emissions or harmful fumes.
Solid-state technology: Solid-State Technology (SST) is the evolution in lithium batteries, safer, more compact, and lighter than conventional lithium-ion. The SST battery is rated for 2,500 cycles to 80%, or about 7 years of everyday use.
Power and capacity: 4,000 watts continuous (6,000 peak) and 2,611Wh can power most home appliances, including refrigerators, making it a strong choice for emergency UPS backup. Protections include over voltage, over current, over charging, over discharging, thermal, and short circuit. Integrated GaN technology delivers power more efficiently, and Yoshino’s U.S.-based support is there for any service needs.
Expandable with Smart Link: Connect additional 2,611Wh batteries to increase capacity and match any application, with no limit, whether you need 10-15k Wh or more.
Connections: The control panel has 10 ports, plus two fixed 15-watt wireless charging pads on top, for 11 supported connections. Ports include two 120V AC (pure sine wave), one 120V/30A RV, two 12V DC, two USB-A, one USB-C (20W), and one USB-C PD (100W). The wireless pads charge devices like the iPhone 14 Pro and Samsung Galaxy S22 while you power other electronics or tools.
Power on the go: A built-in aluminum carry handle makes it easy to move, and a bright LED light is included. Optional Wi-Fi and Bluetooth app control gives you remote access. It works as an integrated UPS when all else fails, on a jobsite, while camping, or in an RV.
Three ways to recharge: AC fast charging takes 0-100% in 90 minutes, optional solar charging takes 5.5 hours, and car charging takes 22 hours.
