Keine macht der Schildkröte

'Nobody does the Tortoise/Turtle' a saying Germany's largest EV YouTuber came up with. When EVs get down to about 5% battery charger, a warning lamp of a tortoise appears & the car will then reduce the Performance.
Over the last two years have got both a tortoise and a turtle from collecting points at a supermarket chain. I always forget the names. One is Schildagard.
But today, I also bought from Amazon a €40 powerbank, also designed to start EVs & ICE cars when normal 12V battery is flat. EVs rely even more on this 'old' technology and particularly certain models from Nissan, Kia & Hyundai seem to suffer from mysterious background usage when car switched off & not being recharged from the main drive battery.
Useful to have on board, hopefully only to help others out! It also has a torch & acts like a normal powerbank for phones etc.
