Can't go wrong with tossing this is your bag before a trip or a conference where you need juice! Laser pointer is fun to mess with the cat with but the pack itself is too bulky to be used as a dedicated laser for meetings, etc. I guess it would work as a backup in a pinch but don't buy this for the pointer. The same can be said about the flashlight. The battery pack works great but you need to make sure your phone is good enough on 1A. Otherwise, this pack will drain faster than it can "re-fuel" your device. If that is the case, like say for my ATT S4 which needs 2.1A to rightfully charge, the best way to use it is with the phone turned off and charging, say mid-flight. Worked much better back on my S2 or my Fiancee's S3 (no our last name won't be Samsung).
