So I just bought a anker usb car charger. To replace a $2 deal extreme cheap charger that I did not trust for charging expensive devices.

I just took a reading off the anker charger, and it is putting out 5.24 volts with and with out a load.

All my other chargers wallwarts and car chargers put out 4.8 - 5.08v.
Any idea if 5.2v+ is a little too much for a device that only wants 5.0v??

No it's fine, just don't forget to unplug your device after charging is completed.

This is not too much. Most of modern 5V devices are supposed to support charging over USB.
For example, according to USB wiki page: "The specification provides for no more than 5.25 V and no less than 4.75 V (5 V 5%)"
So your charger even meets USB requirements .
In fact usually the charging process is controlled internally by the device, so this internal controller will limit the charging current and stop charging if needed.

don't worry, during charging the tension will drop to 5v
