Power charger USB adapter for iPhones 1a 2.4a quality recommendations
I see these chargers and that seems really good deal.
2.4 amp version: http://www.fasttech.com/products/1304/10000105/1244502
1.1 amp version http://www.fasttech.com/products/1304/10000105/1244503
2 things:
What do you think of the quality vs. price of these and
Would the 2.4a version charge quicker? Too quick???
The iPhone chargers are usually 1a. Is that to limit the phone ( would the iPhone draw more current if supplied, or is 1amp the most the phone would draw so 2.4 amp doesn't help any?)

Right - drawn. But is it feasible that the power supply limits the amount of current that a device can draw?
Not questioning you, just taking this to an extreme.... any qualms about plugging in a cell phone or similar to A 100 amp usb supply if it existed? I realize an extreme, but am I wrong to think that the manufacturer could use the max current available from charger as a way to limit (poorly designed?) device?
And another question if you don't mind

Talks about meAsuring current. How are they doing that would you think? With the cell phone connected and DM in line? Tat is only showing the current the cell phone is drawing not the max the power supply could put out? You need a variable load / resistance to increase draw till voltage starts to drop, right? Something draws too much and voltage will drop?.

@BeGentleWithMe-INeedHelp - Thank you. I went to the other post and commented in more depth. I am in my shop right now doing elementary Arduino development and have my big 3A supply on to supply delicate current (turned down the current limiter).
