I purchased a fleaby knock off canon 240V AC to 8V DC PSU. I really only wanted it for the DC out lead and small right angle connector that plugs into the canon DSLR dummy battery.
I took it apart to lo and behold...no protection cctry, extremely poor soldering very poorly laid out and design, no input AC filtering....an absolute disaster in waiting. Probably I expected this but it was really a shock to me. Naturally I just used the lead and tossed the rest.
But some people rely on these to power their DSLRs.....if only they knew....
