What do you guys use (if any) while flashing to stabilize battery voltage?

I'm thinking of getting a CTEK MXS25, which does 25A and has the stable 13.6v supply mode.

Mainly looking for ones when flashing over OBD.

Also, anyone using interesting set ups like modified PC PSUs?

2-5A is enough if all the accessories are off.

I'm currently using a cheap manual (thankfully) 2700mA charger, but I plan to flash some newer cars (EDC17, MED17, SIMOS 10/12/18), and don't want to take any chances. Also, my flash tool doesn't show voltage while flashing, which is bloody annoying.

But I agree, for ME7, MED9, etc.., I expect 5A to be plenty.

AliExpress sell LED drivers (12-16v adjustable and up to 50A).  They're about $30.

https://www.aliexpress.com/item/Best-quality-12V-50A-600W-Switching-Power-Supply-Driver-For-CCTV-Camera-CNC-LED-Strip-Lamp/32605745238.html?spm=2114.01010208.8.4.jH9Gru

That's a 600W one, but they do 400, 200, etc.  They regulate really well and pack a good punch.
