The newly updated Phi 1 Portable produces an optimized multi band scalar field, which helps protect the body from modern forms of electromagnetic radiation, when used with a home unit as your primary protection.
The Phi 1 has a durable and lightweight black ABS plastic case with a triangular, reinforced hole, which you can use to attach a lanyard, chain or string (not included) for ease of carry. The equipped 350 mAH battery provides approximately 2 days of continuous use between charges.
This portable does not come with a charging cord. Charging cables are everywhere these days, so this portable is designed to work with any USB-C charger, whether it is a fast charger or not. Rather than adding another cord to your junk drawer, the portable comes without a charging cord. If you want a charging cord to come with your new portable, add one of our affordable options to your cart. We have curated ultra durable charging cords that are sure to work, in a variety of colors for you to choose from.
For information on charging and proper operation, check out our Quick Start Guide page.
Our Phi 1 Portable emits a multi band scalar signal, where multiple frequency sets are produced that operate in tandem. You will notice that your Phi 1 emits a solid green light most of the time, but every half minute or so, the light will turn off for a couple of seconds. This on-off pattern is designed to keep the body adaptable and dynamic, ensuring a continual response to the field even after many years of use. The light will blink red to indicate that the battery needs to be recharged.
Our multi band home and portable models are designed to protect the body from more intense forms of EMF, like close range 5G, and also to help it regenerate more quickly from any exposure that may still be affecting the body.

Frequently asked questions
Invisible forces are part of modern life, but their impact doesn’t have to define you. Blushield works quietly in the background, supporting a more stable, balanced internal state so you can focus, rest, and perform at your best.
It doesn't block or shield EMF. Instead, Blushield is designed to support the body's natural response to everyday electromagnetic exposure. By focusing on biological support rather than altering environmental signals, it takes a different approach to EMF protection.
Plug-in units (Premium, Ultimate, Phi) cover your home. Portables cover you when you leave it. Most people start with one of each: a plug-in for the house and a portable for travel, work, and the car. If you're not sure, use our Find Your Device tool or message us.
30-day limited money-back guarantee on every device (restocking fee applies - see our full return policy). Stationary and portable units carry a 1-year warranty. If anything extends past that, contact us.
Yes. EMF meters measure intensity, not biological impact. Even low-level exposure from Wi-Fi, Bluetooth, smart meters, cell towers, and nearby homes accumulates 24/7. Blushield works on the body's response, so it helps regardless of what a meter reads.
Some people feel calmer or sleep better within the first night. For others it's a few weeks of gradual change - better focus, deeper sleep, and less fatigue. A small number notice a short adjustment period as the body recalibrates. Everyone responds differently, so give it time to become part of your daily environment and let the benefits build naturally.
Yes. Blushield is built on decades of research into how the body responds to coherent vs. incoherent electromagnetic signals. We have independent studies, HRV data, and live-blood analyses on our Science page. We don't make medical claims. We point you to the data and let you decide.
