Great compact size for easy travel. The unit can be charged while charging a device. A feature that I could not do on the larger capacity New Trent 120T. The unit is near perfect, the only annoyance I have with the unit is the power button. The unit has one button with 3 settings. Tap to turn on the laser, hold the button for USB charging and longer hold for LED flashlight. The button is so easy to push I have opened up my bag to find the laser pointer on. The laser pointer probably does not use that much energy but I do find it annoying that its draining my power reserves. The unit does come with a travel bag which helps keep the button from being tapped on accident but it does happen from time to time.
