The built-in battery with 3000 mAh will accompany most of us well through the day. And if the battery is still empty, it can be further steamed with Passthrough while charging. As intended for the evaporator heads, the battery carrier outputs between 20 and 40 watts. The Unimax 25 Kit is playfully easy to use. You do not have to pay attention to any technical settings. The "Direct Output Mode" regulates the power automatically, depending on the battery charge level. If performance is more important than runtime, Constant Voltage Mode will provide full power until the battery runs out.
