## Questions & Answers

**Q: Can i use it to charge a samsung galaxy watch active?**
A: No.  As watch active charges on this charger it overheats and the watch shuts down the charging and says to use the correct charger.  If I remove watch from charger and let it cool down then return to charger it charges a little farther then shuts down again.  Contacted seller and they said this charger is NOT for the watch active.

**Q: Does this work on galaxy 4 watch?**
A: Yes

**Q: Does the watch display the message "Use Original Charger" with this charger?**
A: Not for me. Works exactly like the one that came with watch.

**Q: Does this unit overheat**
A: If you plug it into a USB outlet on a PC for example, it does not seem to get too warm.  I have used it with a low output power block (1 MAmp) and found that it can get very warm.  The seller recommends using a USB outlet for it.
