How cheap is a cheap power supply?

Link to page: http://www.pcbheaven.com/userpages/how_cheap_is_a_power_supply/ I got from ebay a cheap power supply for my canon camera. It appeared as a normal power supply, with the canon brand printed on the label. It worked fine for some time, and then things turned really nasty...


For $5 you could ...
For $5 you could make a much better power supply by hand lol. 1 scrap transformer, 1 bridge rectifier, 1 big capacitor, 1 small capacitor, and a linear regulator.

I bought a cheap car cigarette lighter to USB adapter on eBay, but it makes my iPod charging icon flash, and there's buzzing in the audio. Made in China = garbage.

Yeaaap, you usually get what you pay for, only few exceptions, and far between... However, if you know what you are doing, you may be able to save some bucks here and there. I liked the WWII salvage bit... :P

Basicly you bought ...
Basicly you bought the same thing as an original one. It's just that the one you got does not have those useless filters and additional protection. The capacitor will burn again if you don't make a filter circuit on the low voltage side, after the diode. It's a simple fix and the only other diference will be the short circuit protection will be missing and if you somehow manage to make a short, you will be left with a gaping whole in the power transistor, aswell as few other blown up components.

You are a retard, I can't watch anymore. Your body is transferring the energy from the power adapter. It's amazing how you can make a breadboard but too dumb to realize what's going on. Get a better translator u sound dumb

Wow I could ...
Wow I could probably MAKE a power supply better than that-and electronics isn't even my college major! The scary thing is that it actually has the CANON logo on it despite clearly (from the inside) not being a canon product. So I could go to the store and buy one that looks exactly like a canon power supply but the only way I would know is to probe the output and the store probably wouldn't even know what I was talking about when I said "It's not regulated properly". Jeez
