This is my circuit (google docs link)
It is powered by (2) 18650 lithium batteries, with protection pcbs. Do the diodes I added provide protection from reverse battery loading and such?
The LM317t should provide 5v and not burn up my iphone?
I dont think any current is drawn in the data lines so resistors work? (An official apple charger had similar design, with resistors so I should be good?) apparently 2 volts at D- and D+ means it draws 500ma
What could potentially go wrong to burn up my iphone?
[or should I buy some cheap chinese portable charger instead?]
THANKs!
