The interesting points on this backup battery model:
- The presence of a USB port on the battery, allowing the need to recharge a device with a port other than mini-USB (on some batteries, it is limited by a cable "imposed").
Points to review:
- The thickness of the battery. Other models, thinner but wider range themselves more easily into the bag.
- Another pressure switch! Why the manufacturers do not they use the switches in the form of slide "On / Off", which informs easier on battery activity?
