800 Watt balkony power stations are generally listed at low hundreds of euros, not thousands; cheap enough to be a no-brainer and sold in budget shops like Lidl.
Mine cost €350, of which €50 was delivery, and €50 of which was a set of brackets to mount on the outside of balcony railings, i.e. it sacrifices perhaps 10 square *centimeters* of balcony space taken up by the overhang in normal use.
(As it happens I have a house with a driveway and chose to not to mount them on the outside of the balcony, but the brackets are supposed to be used that way, I just didn't; YMMV).
