5100mAh capacity for extended use and multiple charges
For Samsung devices with Fast Charge,** charge your battery from 0 to 50% in about 30 minutes*
Qualcomm Quick Charge 2.0-enabled for high speed charging compatibility on even more devices
Charge non-Fast Charge and non-QC 2.0 devices at up to a 2A speed*
The battery charger - first use - charged my cell phone twice without being recharged. Now, I get one cell phone charge out of it. I wouldn't recommend it for any other devices as advertised or for needing more than one charge!
