The Brain Stimulator v3.0 is the newest version of our most popular tDCS device. For this version, The Brain Stimulator has been completely redesigned from the inside out, and has a ton of amazing new features that we’re sure you’ll love.

Push Buttons & Low Battery Indicator

With elegant 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. Additionally, we’ve added a Low Battery indicator LED, which alerts the user when the battery needs to be replaced. But don’t worry, this device will run for over 90 hours at the highest 2mA setting, so you won’t be doing much battery replacing.

Boost Voltage & Constant-Voltage

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 use it!

Current Stepping & Built-In Timer

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.

Advanced Safety Features

When it comes to tDCS, don’t settle for a device which doesn’t put your health and safety first. We believe user safety should be a top  concern when designing a tDCS product. Therefore, we integrated some of the most advanced,  industry leading safety technology into The Brain Stimulator v3.0:

Reverse Battery Protection

Prevents the device from operating should the battery be installed incorrectly and thus potentially damaging the circuitry or producing incorrect results. The device will not power on should the battery be installed backwards.

Over-Current Protection

This feature protects the user from unsafe current levels by limiting the device from ever exceeding 2.25mA at any time. If the device detects an Over-Current issue, the device will immediately cut off current flow and the Low Battery LED will flash RED for 5 seconds. After 5 seconds, the device will shut down and lock for optimal user safety.

Over-Voltage Protection

This feature protects the user by preventing the device from ever exceeding 13-volts at any time. If the device detects an Over-Voltage issue, the device will immediately cut off current flow, and the Low Battery LED will flash RED for 5 seconds. After 5 seconds, the device will shut down and lock for optimal user safety.

Session/Safety Timer

After 30-minutes of use, the device will slowly ramp down the current and power off the device. This feature can be used as a session timer so you can “set-and-forget”

    Insomnia = Yes tdcs works:) I have an underactive thyroid that I believe is the reason for my insomnia. I have taken Zolpidem and Trazadone every night for about 3 years. I’ve gone through a week of about 4 hours/night sleep about 4X a year. Awful. November 2016, insomnia was not being relieved by sleep meds and I was desperate. tDCS was amazing! Immediate effect. Fell into a deep sleep at a 3 setting and woke at the 6am alarm. The effects started to falter a bit after about 2 months but it got me through a bad insomniac period. Since about Feb 2017, I use it about 4-8X a month. If I’m awake after 2 hours, I get up and do the tDCS thing and am able to fall asleep. I love having a plan B. Montage 3 , Red above right eye and black on left shoulder , has been a savior. Hope to learn how to place the wires more easily with my best montage. Best of luck conquering the insomnia monster. I definately recommend tDCs.

    I bought this when the device first came out mostly because of its safety features, which was very important to me. I did a lot of research into tDCS so I knew it was considered fairly safe, but I was still a little nervous about sending current through my head lol. I looked at a few other tDCS devices, but none of they seemed to have a big focus on user safety. I had read 2ma is the recommended maximum for tDCS, but one device I found had a max of 2.3, and another could reach 3ma! The Brain Stimulator sticks to 2ma, and even has an emergency cut off feature if the device malfunctions. There’s even a voltage protection cut off if the voltage goes too high, which I think all devices should have because some of them use like 24 volts which seems excessive. I like that The Brain Stimulator v3 takes a standard 9 volt, but boosts it so the device outputs 12. The other companies say the higher the voltage the better, but I read that high voltage can cause burns. I have never had a problem with this device, and even connected my multimeter during one session once and the device always produced 2.0ma. Overall I’m very happy with the product and it’s a lot of fun!

The feelings experienced during a typical tDCS session can vary from individual to individual, and can be based on several factors such as as the montage (electrode placement) being used, level of current, and length of the session. The most common sensation associated with tDCS is a slight tingling, itching, or “warming” sensation felt at the source of the electrodes. This sensation can often be suppressed by applying additional saline solution, or by applying slight pressure to the sponge electrodes to help saturate the area. Adding additional saline solution usually requires stopping the session and removing the electrodes, however saline can be applied easily and comfortably during a tDCS session by using a saline solution applicator bottle.

In addition the the above, some individuals claim to experience a metallic taste in their mouth, but usually report it to be temporary and only during the start of the session. Sometimes it is possible to experience the appearance of a very flash of white light, however this is very rare and only possible if the device being used does not feature “ramping,” and the electrodes are positioned near the optical nerve (near the eyes). Almost all of the tDCS devices being produced by reputable companies feature this technology. The Brain Stimulator v3.0 features internal current stepping, which another form of ramping technology which results in an incredibly comfortable tDCS session.

Overall, most people describe tDCS as being a relatively positive experience, and some report not feeling anything at all!

Did you find this FAQ helpful?

Reported tDCS side effects are very few, and only experienced by a small number of the population. Some side effects associated with tDCS include a tingling or itching sensation during stimulation, a slightly metallic taste, and occasional redness at the site of the electrodes. Any redness usually fades away shortly after stimulation. An even smaller percentage of the population reports a slight headache as a tDCS side effect, however this also usually subsides shortly after the session is concluded. The most least reported tDCS side effect, which is usually attributed to improper use of electrodes or poorly assembled/prepared electrodes, is skin irritation. Sometimes this irritation can take the form of a small skin bump or lesion. However, it is important to note that even this side-effect is quite minor, and will fade away over a short period of time.

tDCS Side effect organized into an informational graphicWe found a great infographic on tDCS side effects located at, which shows that often most side effects can be attributed to the placebo effect. The results shown below depict that based on clinical trials, those individuals receiving “sham” stimulation (fake, no current) often reported the same symptoms at similar severity levels compared with those individuals receiving active stimulation (real tDCS).

Fisher Wallace produces products that are actually very different from The Brain Stimulator family of products. While our devices utilize tDCS (Transcranial Direct Current Stimulation), the Fisher Wallace Stimulator utilizes tACS (Transcranial Alternating Current Stimulation). In all of the research we have completed on Transcranial Alternating Current Stimulation, it is our opinion that tACS has the potential to produce greater side effects than tDCS, in addition to having less scientific backing. Furthermore, Antal, Boros et al. (2008) found that tACS does not appear to create significant changes in cortical excitability. That being said, we do not dissuade customers from purchasing Fisher Wallace’s products, and in some cases will often recommend their products if we believe it is a better fit for the customer. Furthermore, Fisher Wallace offers a 60-day, 100% satisfaction guarantee.
It is important to note, that while most people believe that the Fisher Wallace Stimulator is FDA Approved, this is not the case. The Fisher Wallace Stimulator is only FDA Cleared, which is quite different from approval. While much progress has been made over the years to gain approval, there are currently no CES (Cranial Electrotherapy Stimulation) devices that have received FDA Approval. The Brain Stimulator is neither FDA Cleared, nor Approved. The reason for this is because The Brain Stimulator is not a medical device, and is not recommended, nor condoned, for use with medical purposes. If you are looking for a CES/tACS, or a device which is FDA cleared for certain medical purposes, we recommend researching Fisher Wallace to determine if their products may be right for you.

Our goal is to produce tDCS devices of the highest quality standards, which operate with precision and guaranteed accuracy, therefore we do not include current meters in our products. Analog current meters are incredibly inefficient, and are only required for tDSC devices which do not have proper current control and management circuitry in place.

Our products include enhanced circuitry comprised of precision components, integrated circuits, and microprocessors (“smart” technology) which controls and monitors current levels several times a milliseconds. The design of our circuitry means that our products do not require a current meter to operate effectively.

However, tDCS devices which use basic, rudimentary circuitry, must include a current meter, as the user needs to consistently monitor and adjust the current flow.

For best results, we recommend you replace your sponges every two weeks, or after 7 tDCS sessions. However the best results can be obtained by using new sponges for each session. Replacement sponges can be found in packs of 10 in our online store. Over time, the sponges within Amrex rubber electrodes can grow brittle and crumble, crack, or split, causing an uneven distribution of current. Worn-out sponges can cause an uncomfortable tDCS session, with increased tingling, itching, and sometimes stinging sensations occurring. A good way to tell if your sponges need replacing is if soaking them with saline solution becomes more difficult, if they start to display a darker/brownish color, or begin feeling “stale.” More importantly, if your tDCS sessions become uncomfortable, or you start to notice sensations that maybe you didn’t before, this is a good sign that your sponges need replacing. You can find 10-packs of replacement sponge inserts for both the 3×3″ Amrex Electrodes and the 2×2″ Amrex Electrodes through our online store.
