@Twointje, well glad to hear the MAAS-50 is put to good use with others.
Based on the discussion I had with the manufacturer, it is just a device I would not recommend.
That it is proven to work well for others is great and I'm not judging anybody who bought & is using one.

The MAAS-50 and K-PO KPS 50 (same devices) are great value for what you get.
Others love to make something themselves, some just use a regular charger.
Let others decide for themselves what they do - as I said, I'm just the messenger.

My personal consideration is a bit different and my preference would be to go for a bit beefier one like the Telwin's. Just don't feel like risking to bricking one or more computers in my recent 5 series.

I got myself the Telwin Doctor Charge 50 and i must say for me this thous the job wel , i cant put it in diagnostic mode or supply mode and regulated the voltage from 12 volt up til 15 volt and regulated the AMP up to 40 AMP ( I know 40 amp is not that much but i noticed that with the ignition on and the lights on and the AC fan on manual on MAX my F10 draws about 30 amp. If i turn off the AC it drops till 20 amp , i have bin playing wit E-Sys fpr about 2 hours without stopping and coding several things and the car never draw more then 18 to 20 Amp. Then i flashed my NBT module to see waht would happen and if i leave the AC of the car never draw more then 30 AMP flashing the NBT module. So for me this is enough because i would never flashed the intire car in one time , i would prefere to flash the models seperatly maybe 2 at the same time. So for me the Telwin Doctor Charge 50 is good enough and i got in sale for only 230 euro instead of 330 euro. Thanks for the good advice.                             Best regards.
