@Capeman I would suggest that the canakit power supply is probably quite cheaply made inside, I have three of them, and all three of them give a small elecrtic shock if you touch the negative part of the cable output.
I should do a voltage test to determine if infact they are using non isolated AC rails inside.

Aukru does some good stuff too AFAIK, with or without power button :

@spruce_m00se i use two canakits. I like them. I have never zapped myself with them. It might be that you built up static electricity easily in your house. Also could be faulty wiring in your house. If you have an open neutral somewhere in your house you could be getting back feed. Most common is at the panel or if you have a bad gfci.

gfci.

its very possible that there is a problem in the house somewhere. its a rented apartment, so I wouldnt bother hunting it too much, I have also noticed the issue at work when plugging it in, but again, also possibly a bad ground somewhere etc.

@spruce_m00se its actually kind of common in business' with a lot of lighting. Idiots have no clue when they are wiring them up. We used to have fun at a place i worked at. There was a little entrance for employees to go behind the glass counters. If you touched the metal on the counters on both sides of you it would juice you. A neutral wire was grounded out on one of the cabinets lighting system. Before i worked there they paid me to find and fix the electrical problem. Then when they moved, i wired the whole stores electrical to make sure it was done right.

@edmaul69 yeh , well I live in Dubai, and the workforce here that do that kind of thing cannot be commented on. so it could well be what you say.

I was reading into brands this morning, apparently the northpada charger you listed is very well made and tested to be a good quality power supply. The cord is short at only 1m, but 3a output is worth it. I'd say that is a good option also.

Right now the connection from my Pi to the plug anyways is only like .5m because i have an extension leading onto my desk because of my home phone.

Hey guys i ended up getting the Enokay Power Supply 2.5A which is working perfectly right now no power issues at all and just wanted to ask if i get something like this will i have any kind of power issues at all for extending it further or no?

You linked to an HDMI mini to full size adapter. Not sure if that's what you meant to do.

Look at the link again because it shows this alt text

@Ecks It might have power issues if the power wires are thin, but one reviewer there doesn't seem to have an issue. In my super famicom mod, I made my own microusb extender with pc psu wires, but my wiring is much longer. Price doesn't seem reasonable. Try ebay and buy from a chinese seller that lists the AWG size. The lower the number the thicker the wires.

Thanks and the reason why i asked about this as well is because i am thinking of installing my Pi inside of my arcade joystick when i make it which i already have a small extension for HDMI and USB just so i could plug in another controller in the future and also just curious if this could be good to use as well alt text because everything is going to be closed up inside anyways so just would like to have an option of accessing the SD card port still.

cable extensions wont draw any additional power
