Any USB charger issues ?

[rolygate]

I'm looking to collect any data on USB charger issues as against mains plug chargers.

Are there more problems with the USB version? If you think so, please post here. For example:

-- Do they fail more than mains chargers?
-- Do they reduce battery life?
-- Do they blow PC (or laptop) USB ports?
-- Any other issues?

Without a doubt they are faster but I'm trying to collect any data that indicates this comes at a price.

Once I used the wrong USB charger to charge a 510 batt. Just before the batt went POOF, my computer switched off. USB port still working. The batt on the other hand died quite convincingly. It did an Osama so to speak.

I just got mine a week ago and the USB plug doesn't make actual contact with the battery in my Ego-t. At first I could twist it a little and it would work. Now it's just a battery that needs charged the usual way. I suppose mine has a 'mechanical' issue.
