A power station is a portable storage device for electrical energy that has a built-in rechargeable battery and various outputs. A display provides information about the (charging) status and the energy consumption of the connected consumers. Usually 12 volts DC (cigarette lighter plug), 5 volts DC (USB plug) and 230 volts AC are available as connection options. Depending on the product, the amperage that can be drawn from the individual ports also changes.
Devices with lithium batteries are much lighter with the same storage capacity. In large parts of the world, 230 volts alternating current (AC) with a frequency of 50 Hertz (Hz) is standard. The United States often uses 110 volts AC at 60 Hz. There is little that can be done with that in Europe. This should of course be taken into account when buying.
It goes without saying that such devices are not intended for connecting large loads such as vacuum cleaners, kettles or powerful electrical appliances.
Many radios are designed for an operating voltage of 13.8 volts and do not work optimally with 12 volts. There are therefore additional devices, so-called "DC / DC converters" (or "Boost converters") that serve this purpose.
If you want to operate a shortwave station with such a device, you should first check whether the built-in electronics are not impairing reception due to interference.
