Unboxing and testing the 20V Parkside cordless soldering station from Lidl. Sorry for the background noise at the middle of the video. It was my neighbor butting some steal.
Never did a time test but I've used it extensively and the battery had no issue keeping up with my work. After every use I push the power button to preserve the battery and if I need to use it again I push the power button again and in less then a minute is hot and ready to use.
