those cheapo chinese supplies can be hit or miss.  some do introduce interference.  I have also heard that they are more prone to cause a fire if they fail.

I just use eneloop rechargeable in mine.

I do have some of those cheap chinese supplies around though, but I try not to use them.

Rechargeable AAs are the safest best. I normally only use OEM PSUs, but they're horribly expensive in the case of the TE, so replacements were the better choice for me.

Here are a few pictures of the internals:


Nothing too worrying except for the lack of a fuse.

After a bad experience with a switching power supply (introduced electrical interferences in my SFAMICOM) I don't think I'm buying anything different than original regulated power supplies and, in my case, a stepdown.
Ouch. What type did you use? Did you make sure the voltage and amperage were exact?
Well, it has the exact voltage but gives a little more A than the SF needs, so it's ok in terms of characteristics. At the beginning I thought my PVM was having the failure, then I changed the power adapter for a generic brick and voilĂ , no noise into the image. Here I saw myself saying "what the frak, stepdown and end of story".

Now the effin switcher is somewhere in the just-in-case-bin.

I have a couple of cheap 3 in 1 AC adapters that cause interference on SNES, NES, Master System, Genesis, etc.

Yeah, I wouldn't go aftermarket for consoles where it's so easy to get cheap OEM PSUs. This TE PSU seems to be good though, and doesn't cause any interference or other issues. It's exactly the same as AAs in my tests, both on my 2.5" TFT and when plugged to a TV. I'm only recommending it because TE PSUs are so expensive. If you can get OEM inexpensively, I'd say go for it. If not, these will do.

Mine arrived today, worked fine through about 30 minutes of use.

The cord is a bit shorter than my official AC adapter or my Naki one. It might be a good idea to buy an extension cable with this one with all the money you saved.

Thanks guys!

As long as the TE is centre positive then it has the right voltage and enough ampage. Seems cheap but if it lasts a while good enough.

Thanks, I can't find any other choices tbh in Europe or Uk that are not more than 20 pounds (and they are all unofficial). Problem is I am not entirely sure what to search for too ;(

Awesome, thanks again Wildfruit. I have never seen that before. I think I will go for it and if I do, I will report here impressions.

Edit: btw, it looks exactly the same with the cheap chinese one in the photo :S http://www.ebay.co.uk/itm/221227273063?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

It probably is the same one.
