Compact and portable battery. Button control charge and discharge of 3 light level. USB port to charge the phone and micro USB port to charge the external battery. A USB to Micro Usb provided for both actions, handy if you have a phone with micro USB. Battery 2600mAh / but for me not load my phone 2300mAh / as 80%. Charge 2:30 I find a bit long. Some connection bug first use, charging the phone off and then resumes. No longer do so since to do with time.
Compact, lightweight and convenient for short trips because it lacks a bit of power for my phone but for the price it satisfied me for emergencies or battery phones is increasingly lacking.
