Take a tip from what Pro Photographers do, they carry extra batteries when doing their photography
This is a fast charge battery and will charge your phone 1.5 times faster.
The newer Smartphones have fast charging. I can charge my phone up with the charging unit or this battery back up unit in about an hour. That is much faster than my old charging system.
How the phone hooks up to the battery. Cord comes with battery.
Sometimes you don’t have time to charge your phone on the go. Or you are close to an AC outlet to charge up your phone. That is where this fast charging backup battery comes into play. I just grab it and go. While in the car it is fast charging my phone.
Keep in mind you must have the right charger to charge up both the battery and your phone.
The cord has two optional connectors for charging the battery (shown here) or charging your phone.
