How can I lodge a complaint with Apple about quality of products?

There is no "complaint hotline" and here is not the right place, either.

You could try <https://www.apple.com/feedback/>, but it might be better to call Apple Support <https://www.apple.com/support/contact/>, or go into an Apple Store (if one is nearby).

However, I would say that if you are going through charges this quickly, I suspect that your electric company's power is suspect. I've only lost 1 charger since my first laptop in 2000 (I've had 5, and my wife has had 6 laptops). I've followed Usenet News Groups and these forums for years, and you are the first person I've read about reporting so many charger failures. So while you may be very unluckly, I still think it might be something in your environment that is affecting the chargers.

I am about to purchase my fifth or sixth charger for my 13' macbook... of this last year and a half!! I am so unbelievably frustrated with the quality of my charger and the fact that these have to be replaced so often for products that, in just a few months, will stop working.

That would be extraordinarily unusual for a charger - virtually unheard of. Are you buying genuine Apple chargers or eBay/Craigslist junk? If you are buying Apple chargers, then you need to have your computer checked. Chargers are simple and there is very little to break there. MacBooks, not so much...

lehath9, I don't know if this is the issue you're referring to, but I, too, am terribly frustrated by the amount of money I've spent on genuine Apple chargers in the last 18-24 months.

I believe the quality of the chargers has declined significantly and have had to replace, several times over, the chargers that came with my 2nd generation iPad, my iPhone 4S and the latest iPod touch. The cables/wires are breaking and fraying.

I thought perhaps I was being too rough on my cables somehow the first couple times that it happened, but I know that's not the case now. For comparison, the cables that came with my first two iPod classics and my first Nano are fine. I also took an informal survey via Facebook to see if others have noticed the same issue and got about 20 affirmative responses, all of which stated the problems started with chargers sold in the last 18 months.

I've purchased four replacements in the last six months and the third of those 4 is now broken, exactly as the previous 2 replacements and exactly like the three before those. The rubber/plastic casing for the wires pulls away from the non-USB part of the charger (the end that goes into your ipad/iPhone/iPod). Once it pulls away the wires are no longer supported and they start to hang at an odd angle (no matter how careful you are plugging, unplugging and positioning the charger in the device) causing them to break and of course preventing a charge from reaching the device.

I bought my first Apple product,a Macpro, just under a year ago, and my charger simply stopped working a few days ago. Having used many windows based machines (Toshiba mostly, Compaq, etc) without any power supply failures over the years, I wonder whether there is a raliability problem with the Macpro adaptor - cheap components, mainly. It is a simple device and should be reliable.

Assuming it hasn't been physically damaged return it for warranty replacement.
