Issues:

• 12V supply is below the minimum compliance voltage of 20V for tDCS; insufficient for tDCS.

• When the device is turned off, the device is still running in the background—causing the battery to drain.

• LED does not display the true output, no real time current level.

• No ramp-up feature, can be uncomfortable for some users.
