General Information
The E.FLEX is a sleek solar charger incorporating a simple plug-and-play feature to keep
USB devices charged. Charge devices such as smartphones, tablets, and MP3 players
faster and efficiently thanks to the new smart auto-optimization feature. With its ultralightweight and compact design, take the E.FLEX anywhere for a true on-the-go charging
experience.
Key Features

Included suction cups for easy window charging
Smart Auto-Optimization Charging
When charging through solar, the charging rate changes based on the presence of clouds
or shadows cast by trees and objects. This causes the solar power to underperform and
reduce the rate of charge. Upon recovering the full solar charge, many chargers will not
increase the charge, but instead continue to charge at their reduced levels. This means
that your USB devices would be taking longer to charge and you (unknowingly) would
have to disconnect the device and plug it back in to recover the lost charge. Thanks to
the smart auto-optimization technology in the E.FLEX, this issue is resolved automatically
giving you a worry-free charging experience.
The E.FLEX analyzes the power flow being received to make sure the USB device can
charge as efficiently and as quickly as possible based on the solar power provided. This
smart auto-optimization technology will be able to recover reduced power (caused by
shade) by integrating a 90-second power flow check. When illumination increases, the
E.FLEX will determine the power requirements of the USB devices and recover charge
accordingly.
Be mindful that heat affects all electronic devices. Therefore, it is heavily
recommended that charging devices not be exposed directly under the sun. Apple
products are known to activate their heat protections which makes charging unstable.

Operation
To charge USB powered devices, simply unfold the unit on a nice sunny day and plug
your device into. For stored charging, connect a USB powered battery to have longerlasting power.
As an added bonus, turn your E.FLEX into a window charger that you can conveniently
use inside your car or at your home.
Note that this may not work with windows that have UV resistant tint
