6. Uninterruptible Power Supply (UPS)
Note
To use the UPS function, connect your portable power station to a wall outlet with the AC charging
cable, then press the button and connect your devices via the AC Outlet ports.
This product supports offgrid UPS. When you connect the grid power to the AC Input Port of the
product through an AC cable, you can power electrical devices through an AC Output Port (AC power
will come from the grid and not the portable power station in this situation). In case of a sudden
blackout, the product can automatically switch to the inverter mode within 20ms. As an offgrid UPS,
this function does not support 0ms switching. Please do not connect the product to any device that
requires 0ms UPS, such as data servers and workstations. Please test and confirm compatibility before
using the product as a UPS. We recommend that you only charge one device at a time and avoid
using multiple devices simultaneously to avoid triggering overload protection. Yoshino assumes no
responsibility for any device failures or data losses caused by misuse of this product.

10. FAQ
1. What battery does the product use?
The product uses a solid state Li-NCM 16.2A battery.
2. What devices can the product’s AC output port power?
The portable power station’s AC output ports can power most household appliances. Before connect-
ing an appliance, confirm the power of the appliance to ensure that the sum power of all loaded
appliances is lower than that of the rated power (2000W rated/3000W max).
3. Capacity
Multiply the capacity of the portable power station x 0.95 x 0.9 / device rated power. The 0.95 and 0.9
are DOD (depth of discharge) and inverter efficiency values. Let’s use the B660 SST and a 60W CPAP
machine as an example. The calculation would be 602wh x 0.95 x 0.9 / 60W = 8.5 hours.
4. Can the B2000 SST charge and discharge at the same time?
