Hi @ sami.jayne,
If there is no led display on the T95, use a DMM (digital multimeter - voltmeter function) to check if the power adapter’s voltage output is OK.
As best that I can determine the voltage / current output for a power adapter for a T95 box is +5V DC / 2A (2000mA). It should be stamped on the adapter itself.
If it is OK and if the T95 is new out of the box, contact the seller as there is a problem in the box.
What is the “brand” name of the T95 Android box that you have?
