I understand that the iPad charger puts out higher voltage than those provided with the iPhone.
Other than the microscopic type on the units themselves (which my agings eyes cannot discern) is there a way to identify which 'cube' is for which device?
I.e. phone vs. pad?
I have several that have accumulated with the purchase of various iPhones and now an iPad.
Obviously I'd prefrer to use the one that was designed for the iPad to charge that device.
Thanks for any help in telling them apart.
John
