tDCS-Ultra is a hand-held battery-powered limited-output direct current source. With precision micro-controllers and medical-grade design and fabrication, the tDCS-Ultra provides quality and precision, which is not something that should be compromised in tDCS. The tDCS-Ultra has a unique and simple user interface that allows simple selection of current intensity (1, 1.5 and 2 mA) and time (10, 20, and 30 minutes). tDCS-Ultra automatically ramps current up at the start of stimulation to the prescribed intensity and down at the end of the prescribed time. This automatic control is critical to ensure a precise dose is delivered and the current ramp on and off provides comfort and consistency. tDCS-Ultra includes an abort feature which allows you to safely interrupt stimulation for any reason. The backlit display clearly indicates stimulation settings, status, and low-battery warning, all features we consider essential for consistent and safe tDCS. Finally tDCS-Ultra uses a proprietary voltage-management system that ensures comfort while guaranteeing target current across expected body resistance. What all this means, is that users can trust the tDCS-Ultra to provide the most precise and reliable stimulation, in a affordable and compact package. Combined with caputron head-gear and electrodes, the tDCS-Ultra made to medical and research standards allows you reproduce any stimulation in any tDCS clinical trial or publication. Capturon, the trusted leader in neuromodulation distribution, is proud to provide the tDCS-Ultra hand-held high performance stimulator.

How it Works

tDCS-Ultra is extremly easy to use. When turned on, the device will default to 1 mA and 10 min. Simply press anywhere on the Intensity and Duration buttons to toggle between the different options, 1 mA, 1.5 mA, 2 mA / 10 min, 20 min, 30 min respectively. When the desired Intensity and Durations are selected, press Start and tDCS-Ultra will take care of the rest. If for any reason you need to stop stimulation, simply press the Abort button and tDCS-Ultra will safely ramp down the intensity.

Device Features

  • Intensity settings - 1 mA : 1.5 mA : 2 mA
  • Duration settings - 10 min : 20 min : 30 min
  • 40 Volts standard - 20 Volts available upon request
  • Dimensions - 4.74" x 3" x .85" - The slim, compact, and durable design of the tDCS Ultra allows it to fit comfortably in your pocket, hand, or backup without worry of damage
  • Weight without battery - 3 oz
  • Weight with battery (One 9V battery required for operation) - 5 oz
  • H3.8 connection, similar to the connection used in the Activadose and most TENS stimulators

no good

the V2 is not working very good, pls refund me

Hello Shelley, sorry to hear that. We have sent you an email to resolve the issue.

Excellent unit and convenient size

I've had this unit for two months and it works flawlessly. Its small enough to fit in your pocket so I can do things during a treatment. Although it doesn't have all the displays of the Active Dose 2, it's cheaper price and smaller size works for me.

simple yet reliable

I try every device that comes out and this one was great. It is super easy to use and bright leds show you exactly what is going on with the device. The current output was incredibly accurate and the device very well calibrated.

recommend by a friend

A friend of mine uses this device and told me to get it. It worked to help with my anxiety!


this device easily fits in my pocket or in my backpack so I am able to take it with me when traveling. I have been using it for insomnia and it has worked wonders. I don't go anywhere wihtout it.
