The CELLER8 Max uses modern solid state technology because it delivers a cleaner, more consistent PEMF signal than older spark gap systems. Spark gap is an outdated method, first used over 100 years ago, that creates a pulse by jumping a high-voltage spark across an air gap, a process that generates large amounts of unwanted high-frequency “electrosmog” and produces an inconsistent, crude waveform that changes with factors like humidity. Solid state electronics, on the other hand, allow precise control over intensity, frequency, and pulse shape, ensuring a reliable and repeatable signal without unnecessary electromagnetic noise. This makes solid state not only more efficient and safer for long-term use, but also better aligned with delivering the clean, research-backed PEMF performance we designed the CELLER8 Max to provide.
