The reason I picked the one from Australia is you can customize the specs to what you want and IMO is reasonably priced compared to the Deutronic models which are approx $2K. The Deutronic are adjustable in voltage but I used the specs I posted to get a constant 13.8v. Using 14.2v spec, taking into account ignition on, will be about 13.8v. Again, I just took my specs from what I could find from the Deutronic model used by BMW.

When you turn the ignition to Position 1 this will draw some power. Same if you have any accessories on. Obviously, you don't want to have accessories like the radio, fan, etc on.

The main reason the Australia one is expensive is the shipping which was $75 for me.

Again, I just want to remind everyone my experience so far: all my prior coding was not using any charger or PS. Ask Justin if we used a charger/PS when replacing his instrument cluster at the Connecticut meet. Hint: The answer will be NO.

IMO if your car has a good battery you probably don't need it if your doing the stuff I've been doing so far. The charger/PS, for me, is just a pre-caution in the future.

If you ever had to code a module for an extended time or will be doing extended diagnosis (more than 15- 30minutes), then definitely get the charger/PS.

Hi Twin, if you use SSS to code your bmw, you must have at least 13.5v or higher. Voltage below 13v will not be enough to start SSS program, SSS prompts you to connect a battery charger and restart SSS. In normal case, your vehicle battery (if in good condition) only provides up to 12.5v, no chance over 13v. That's why I am searching for a good but not expensive power supply. I am currently using SSS v31. Right now, I found that the Ctek 7000 model is the best choice, cheap and good quality. Maybe 15000 or 25000 model is better, but much more expensive.

The Australian one is also a good product, I believe, but pretty heavy, 3 kg, and as you said, shipping cost is too high, almost a quarter of the selling price.
