A micro USB external battery pack with the specs : 1900mAh with output 5.0V 800MA

but my friend told me that these types of products will damage my phone's battery life. I want to fact-check on this?

thanks!

hi guys... i recently got my s2 and released that it was not my phone that is slow but my own unifi wifi is damn slow.  i don't know why is this the case as my home computer connected through wifi is fast 600++ kB/s Download and 1000++ kB/s Upload.

Anyone has the same issue?  Need help to fix this.
