IPhone 5s charger keeps breaking?

So I know a lot of people have problems with the chargers and I've already gone through 3, my original charger and 2 replacements. One if the replacements wasbt compatible and my sister broke the other one and her original one. I decided to get the most expensive one at walmart, it was like 28.60, with tax it was almost 30. So I'm guessing its a good brand and I'm testing it out now and it works great. I want to make this one last because I can't afford to buy a new charger every month, I'm a teen and my allowance isn't that high. Any suggestions or tips to keep it from breaking?

Is there a charger for iPhones that you just the place the phone on it to charge?

My iPhone 5 just died thanks to what I believe is a faulty charging port. I was looking to buy a new one ahead of my upgrade because the battery life was also giving me a hard time, but I have pictures on my dead one that I have not transferred to my computer and would like to recover.

I believe I've seen devices where you place the phone on some kind of device and it will charge. I don't really know how to describe it because I've tried to Google what I could and without success. Can someone confirm there's a product like I'm trying to describe and if it would still charge my phone despite the bad charging port?

How to get photostream photos back on an iPhone 5?

So I took a picture ages ago on my iPhone 5 and I then deleted it from my photo album, but since then I have took loads more photos and since photo stream only holds 1,000 photos, the picture has now deleted from my photo stream. I now want the photo back. I haven't backed up my phone since I took the photo so I couldn't get the photo back through that. Is there any other way to get the photo back?
