Can I travel with Transcend on commercial flights?

Absolutely!  You are able to fly with your Transcend CPAP device!  Further, because it is a medical device, your Transcend Micro will not count as one of your carry-on items.  Your doctor can provide an official letter stating that you need to carry your device with you, if necessary. Transcend is FAA-approved for inflight use with a battery. Be sure to call the airline in advance to clarify procedures and in-flight policies.
