and support your club or charity for free. Bluetti makes portable power stations and solar energy solutions. These are large batteries with a built-in inverter, allowing you to power devices without a wall outlet. They often have multiple connections: 230V outlets, USB, USB-C, and 12V cigarette lighter. Capacity ranges from compact models for camping or on the go to heavy-duty units that can temporarily power home appliances or even an entire house. Charging can be done via mains power, a solar panel, or a car. They are known for their relatively high capacity, solid construction, and quiet operation compared to gasoline generators. Downside: they are heavy and expensive, but useful as an emergency power source or for off-grid use.
