Yoshino B4000 Solid-State Portable Power Station

Substantial stored energy, with the connections to plan a setup.

The Yoshino B4000 is a standalone 120V power station with 2611Wh of storage and 4000W total AC output.

For selected compatible plug-in equipment, the B4000 gives you separate capacity and output figures to work with. Its manufacturer-described solid-state Li-NCM battery chemistry identifies the storage technology; the load, charging limits and physical size remain the practical checks that shape your setup.

Separate the energy budget from the power demand.

The 4000W total AC figure is the combined output specification, not a rating to apply independently to every outlet. Check the connected equipment and the manufacturer’s outlet and operating limits when planning the load.

The 2611Wh capacity describes stored energy. How long it supports a setup depends on the devices, their operating patterns and conversion losses. This page does not promise a fixed runtime for a refrigerator, appliance or other load.

Choose a charging route that matches the input.

AC charging is listed for 100–120V, 50/60Hz, with an 1800W maximum input. The solar input is listed at 12–60V DC, up to 10A and 600W. Match all applicable voltage, current and power requirements when selecting a charging source.

At approximately 53.6lb, or 24.3kg, this is a substantial unit to move. Plan where it will be used and how it will be carried before choosing it for a mobile setup.

The station and its listed connection accessories.

The accepted package list includes one B4000 SST station, AC charging cable, car charging cable, MC4-to-XT60 solar charging cable, cigarette-car female output cable, standard MC4 solar connection cable and user manual.

Solar panels and expansion batteries are not included. The supplied solar connection cables do not mean that a panel is part of the offer; any panel must meet the station’s input requirements.
