Are my AC to USB power supplies interchangeable?
Background......I have two AC to micro USB power supplies. One says blackberry on it and has an output of 5v-750mA, the other says plantronics on it and has an output of 5v-600mA. They look very similar, so I am worried that I may accidentally use the BB charger on the plantronics device or vice versa.
My 2 Questions.....
1) How important is that 150mA difference in the two power outputs? Should I worry about damaging either device if I charge it using the wrong charger?
2) I have a USB to micro USB adapter cable. Can I use this cable plugged into my laptop's USB port (that has an output of 5v-500mA) to charge the above mentioned devices without fear of damaging them or my laptop?
I realize that you can make no promises on either of these questions, and that nobody can ever 100% accurately predict how any device may react to even minor differences in charging mA's. My questions are basically just about what one might expect to be the case based upon the limited info given. Thank you for any help you may provide.
FOLLOW UP : Ok I get that I can use the laptop to charge either device, but it will likely take longer than if I used the charger. However, I still don't know if either of my devices can be harmed by using the incorrect charger as inquired about in question one.

the 5vdc/750 mA supply can replace the 600 mA supply if the connection & polarity are OK but the 600 mA one maybe overloaded & burn out.

there's a evaluation of the product from a shopper who offered the product. "i offered the computing device potential to bypass and expected the 9 hours of prolonged battery existence on my computing device. regrettably the product isn't waiting to potential laptops for that long...or maybe close. it provides you with one extra 0.5 hour of computing device battery existence. this is it. i'm returning this product the next day. The product works nicely for smaller electronics like cellular telephones and ipods yet no longer laptops. do no longer anticipate the international from this product."
