This portable 15,000 mAh battery is a power bank specifically designed for the visually impaired.  It can be used to charge an array of digital devices including iPhones, iPads, iPods, Android smartphones and tablets, Bluetooth headsets, MP3 players, GPS, and more.
Indicator Features for the Visually Impaired:
Sound or vibration signal for battery level indication
Battery level at any instance is indicated in different sound or vibration patterns.
One to four tones and vibrations indicate the remaining power left in the battery. Fully charged, the battery will sound four tones and emit four vibrations. Each tone and vibration represents 25 percent with a total full battery with four tones being 100 percent to 75 percent full, three being 75 percent to 50 percent full, two being 50 percent to 25 percent full, and 1 being 25 percent or less.
All this can be easily checked by pressing the single button on top one time.
Output power connection confirmation
Sound and/or vibration signal to indicate successful connection between any of the USB outputs and the digital device being charged.
This will be indicated by two tones and vibrations sounding three times separated by several seconds between each sound. After three times, the battery is silent until another action is performed.
 Input power connection confirmation
Sound and/or vibration signal to indicate successful connection between the micro-USB input and the power source for charging
 This is indicated by a single tone and vibration sounding three times with several seconds between each sound. After three times, the battery will be silent until another action is performed.
Reversible USB output ports
User can easily connect any USB charging cable without worrying about the plug's orientation or the cable's direction.
The full sized USB end of your charging cable for your device will go in no matter which way you have it turned. You will never have to worry again about which way you have the USB turned as it will go in the ports whichever way you have it turned. Imagine a USB port that acts like an Apple lightning port where there is no right or wrong way in which to plug in the USB plug. This is a major innovation in USB plugging.
 Optional sound and vibration alert modes
Easily switch between sound and vibration modes by simply pressing a single button.
Press and hold down the single button on top of the battery to switch back and forth from tones and vibration to vibration only. Use it in vibration only mode to be able to discretely check the battery level without alerting or disturbing anyone around you. Perfect for areas where quiet is a must, or when you find yourself in a loud crowded area where tones cannot be heard. Instead, feel the vibrations rather than try and hear the tones. Perfect for any environment or situation you find yourself in.
