if the connector fits and it does not output higher than 5volts (no usb charger would ever output higher unless a rogue scam product)
and the connector fit a charger can never harm your battery, watt = volt * current
and devices do not draw more current than they were build to charge with, so one can have an overspec'd charger which is able to provide much more current than is being drawn but that will not harm, like your car which can drive 160Km/hour is not harmed by driving 50Km/hour in a city arear.
