How much power does the SmartphoneGrip deliver to charge my smartphone while the bike is in motion?

The SmartphoneGrip delivers an inductive charge of 7.5 watts (1.5 A@5 V) with an efficiency > 67 %. 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 require more charging power during inductive charging than is standard and provided by the SmartphoneGrip. If inductive charging via the SmartphoneGrip does not work for this reason, simply connect your smartphone to the SmartphoneGrip via a USB cable to charge it.
