The powerstation is perfect with a lot of details better than the OUTIKEL P2001 EU except of the fan volume. If I switch on the AC-Mode, the fan is running continiously even tere is no electricity consume. The previous version, P2001 EU, the fan was only running with electricity consumers with 1200 Watt and more. I use it in my mobile home and for me it's not good to hear the fan even if I hav non consumer on, or a low consumer on. I this case the older version was perfect and therfore I will not keep the new version. Sorry and best regards.
