I am trying to find a way to recharge my batteries using a car battery (12 volts).
I tried to use a AC/DC converter to get 230V: https://www.amazon.de/gp/product/B076P6WHS1/ref=ppx_yo_dt_b_asin_title_o06_s01?ie=UTF8&psc=1
and then using a 5 in 1 charger:
https://www.amazon.de/gp/product/B07K4BLN4V/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

Didnt work, the converter shows an error and everything kind of restarts..

any ideas?

I have a seperate car battery with an adapter: https://www.amazon.de/gp/product/B014KJZ85I/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

Hi!
You might be better off posting your question in the 'products' section of this forum.
That is way more active.

I did. Can someone delete this one?
