The Brain Stimulator v3.0
The Travel Model
Our new and improved Travel Model Version 2.0 is the coolest tDCS device we’ve ever built! We listened to your feedback and made some updates to our original Travel Model. The main change in our new version is the addition of a small, current-indicating blue LED light. Now the Travel Model will have the same ON/OFF visual indicator just like the original Brain Stimulator has. You’ll never again have to worry about leaving your device on and draining the battery! When the device is switched on, the LED will illuminate, informing you that the device is on and current is flowing. When you’re done with your tDCS session, just switch off the device and the LED will turn off as well.
We also programed additional functionality so that the LED indicator light also functions as a low-battery indicator! As the internal 9V battery looses power over time, the internal circuitry will track the available voltage to determine the battery’s health. As soon as the battery starts to loose its effectiveness, the LED light will start flashing, alerting the user that the battery needs to be replaced. We are the first company on the market to implement low-battery technology into a tDCS device. With this new functionality, you can be sure that your tDCS device is always performing at the highest standards possible.
On top of the added LED, we completely replaced the detachable electrode cable which comes with the device. The new electrode cable utilizes a much smaller, 2.5mm jack as opposed to the 3.5mm jack used on the original Travel Model. Additionally, the new white cable fuses the Anode and Cathode wires together, similar to the wires used with headphones. The fused cables have the ability to be pulled apart (so they’re two separate wires) so that you can alter the cables to reach those hard to reach montages.
The Brain Stimulator
With push buttons and 5 indicator LED’s, this device is a breeze to use. The “UP” and “DOWN” buttons are used to select between current levels, while the “OFF” button functions as an “instant-off” feature, allowing the user to immediately end a session. We also added a Low Battery indicator, which will alert you when the battery needs to be replaced (90hr+ battery life).
Just like our other tDCS devices, The Brain Stimulator v3.0 uses a standard 9-volt battery. But to improve efficiency, special voltage boosting technology has been implemented, allowing the device to operate internally at a full 12-volts (+/-0.5V). So regardless of the electrode position you’re using, you can be sure the device will produce accurate current. Additionally, we reprogrammed The Brain Stimulator to include a “constant-voltage” system so the device operates continuously at 12-volts, regardless of battery health. This means that, unlike other tDCS devices, you will receive the same level of effectiveness out of The Brain Stimulator v3.0 each and every time you turn it on.
The Brain Stimulator v3.0 features intermediate current stepping in-between the four selectable current options. In other words, when you increase the stimulation current from 0.5mA to 1.0mA, the current output pauses momentarily at 0.75mA before reaching 1.0mA. This provides for smoother transitions and an incredibly comfortable tDCS experience. Additionally, you can put away that kitchen timer because we integrated a 30-minute session timer! This new feature gently lowers the output current and turns off the device once the time limit has been reached.
Finally, we've included some of the most advanced safety features in the industry, such as Reverse Battery Protection, which prevents the device from operating should the battery be installed incorrectly. Over-Current Protection, which prevents the device from ever exceeding 2.25mA at any time. Over-Voltage Protection, preventing the device from ever exceeding 13-volts at any time, and of course, the 30-minute session & safety timer. Once the time limit is reached, the device will slowly ramp down the current and power off the device.

Depression is like being trapped in the jungle… Like a marine behind enemy lines trying to survive and trying to find something, anything, a freakin’ stick to fight your way out. Well, The Brain Stimulator is a machete. Thanks for my machete, and I wish you luck getting them distributed to my fellow marines!

I bought the Brain Stimulator after reading about the effects of tDSC on mood and depression, and I’ve been very, very surprised by the positive effect it’s had on my mood. My ability to focus has also improved markedly. I’m still sorting out how to most effectively use tDCS, but I was taken aback by how quickly it helped me. Also, just a shout-out to their customer service: I mistakenly purchased the wrong replacement sponges, and when I asked for a return/exchange, the company responded very quickly, with no hassle, and refunded the difference of price. Yay!
