Departing from the conventional old school chargers with battery trays, the FOURSEVENS Flex Charger fits right in your pocket to go wherever life takes you. With the USB interface, you have the convenience of being able to charge from a wall plug, laptop, external battery, or pretty much anything that provides power through a USB port.
No need to worry about shorting out your battery with the FOURSEVENS Flex Charger. The contacts are not specific to either the positive or negative terminals; just make sure that one contact is attached to each of the two battery terminals. The magnetic charging leads make sure your battery is always properly connected and receiving power, while the internal electronics of the FOURSEVENS Flex Charger automatically match the output of the charger to the requirements of the connected battery.
Once connected to a power source, the light at the base of the cord will change color depending on the status:
- Blinking Red: plugged in, but not currently charging a battery
- Solid Red: charging is underway
- Solid Green: charging is complete
