How much power does the SmartphoneGrip provide to charge my smartphone while riding?
The SmartphoneGrip delivers an inductive charging power of 7.5 watts (1.5 A@5 V) with an efficiency > 67%. The efficiency depends on the distance between your smartphone and the SmartphoneGrip. The charging power via USB port is 5 watts (1 A@5 V).
In rare cases and depending on the manufacturer, your smartphone may demand more charging power during inductive charging than is standard and provided by SmartphoneGrip. If inductive charging via the SmartphoneGrip does not work for this reason, you can alternatively connect your smartphone to the SmartphoneGrip via USB cable to charge it.
