Will increasing trasmit power of WNDR3800 brick the router?

When I upgraded from Chaos Calmer to 18.06, I noticed that the transmit power drop down option now has 794 mW. CC had upto 398 mW. Is it safe to choose the max tx power option? Has anyone having a WNDR3800 choosen the 794 mW without damaging the router?

thank you.
