There's no shortage of iPhone battery packs on the market, but few are as well thought out as the NomadPlus. This smart backup battery sits between your phone's charging cable and the wall wart itself, letting you slide the white pronged square into its black body and connect your charging cord to the other side. Plug it into the wall, and once it's done charging your iPhone, it'll fuel up its internal 1500 mAh battery, giving you a 70% additional charge when you need it the most without forcing you to use a bulky battery case or carry around an extra power brick.

This slim, pocketable device connects to your phone over Bluetooth, and should you be approached, with a single button press takes a picture using its built-in camera, initiates a flashing light and audible alarm, and dispenses the highest concentration of pepper spray available to law enforcement. In addition, the picture, your GPS location, and any other authorized information is automatically sent to the 24/7 monitoring service, which can then notify the authorities.
Hardcore handymen can tell you that thermal imaging is a lifesaver for finding water and air leaks, spotting overloaded electrical connections, and many other household issues.
