Universal Spare Battery Charger With USB Port

Spare battery chargers allow you to keep a fully charged battery available so can avoid long charging times.  When your phone's battery is running low, just replace it with the fully charged one and you're ready to go.

Features

• Adjustable charging prongs and sliding holder allow you to charge any cell phone battery
• Plugs directly into a wall outlet.  Folding prongs for easy storage.
• USB port allows you to charge your phone simultaneously with a USB cable (sold separately)
• LED indicator shows when the battery is charging and fully charged

Instructions

• Slide the 2 adjustable charging prongs so they line up with your battery's positive and negative conectors.  Many batteries have 4 connectors total so you can determine which are positive and negative with trial and error.  It is often the first and third connector.
