Stored power first, with manual generation alongside.

Choose the stored energy for your range

Choose between the 200 Wh and 260 Wh 18650 lithium-ion battery configurations. The battery stores energy for the USB, DC and AC connections, while the external crank provides a separate way to replenish it. The top handle keeps this battery-backed format portable.

Lighting and connections within reach

Two round lamps sit on the side, alongside the charging connection. The front panel provides USB and AC connections; the shared 12 V DC port serves both output and charging, with center-positive polarity.

The 220 V AC output uses a modified sine wave. Select equipment that accepts this waveform, and match the load and connector to the ordered configuration.

ConnectionSpecification
USB5 V / 2.1 A × 2
DC12 V; shared output/charging port; center positive
AC220 V; modified sine wave

See the system at work

The front display brings generation current, generation power and battery status into view. It helps the operator follow the system while cranking and using stored energy.

Three ways to replenish the battery

Use the hand crank or the supplied external power adapter to charge the battery. A solar panel is a separate purchase and must match the required input voltage.

Hand-crank generation varies with speed, from 5–50 W and 1–4.5 A. Generation power describes energy being replenished; battery energy in Wh describes storage. These figures serve different purposes when planning a power supply.
