The Brain Stimulator Basic tDCS Kit The Brain Stimulator is a high quality constant-current regulated tDCS device. The product features an LED light to indicate wether the device is on or off. Attached to the device is approximately 3 feet (1 metre) of lead wire so you will have plenty of room to get comfortable during a session. Additionally, we've implemented an internal capacitor to filter out any unnecessary AC (alternating current). We use only precision components in our circuitry to produce high accuracy and consistent reliability. Additionally, all of our components are professionally soldered onto a specially designed printed circuit board, and securely mounted to a durable plastic enclosure. We've improved the design of the circuitry and internal layout of this device over time, to ensure that the probability of any component failing is enormously reduced. Included with The Brain Stimulator Basic tDCS Kit, are four Professional-grade self-adhesive electrodes, so you can get started with tDCS right away. If you want to get creative and explore other placement areas, we sell several adapters that allow the device to be used with more comfortable sponge electrodes. The Brain Stimulator features a battery life of around 175 hours of continuous usage, and every device is hand made in Southern California using parts sourced from companies located in the United States.
