The Blushield U1 Ultimate Portable 2nd Edition is the best of the best EMF protection in a mobile package. The U1 is a quantum leap in portable EMF protection technology, breaking through what was previously thought possible. It offers the same generation of the dual band circuit as is found in the C1 Cube,  Premium Ultra and B1 Premium Cube.

Blushield has updated the algorithm to provide the best portable protection against 5G radiation available with a coverage range of 5 meters or 16.4 feet in all directions. Read more about the Phi Ratio Frequency in a great article from our friends at Blushield USA.

The U1 Ultimate Portable 2nd Edition is precision CNC machined out of aircraft grade alloy, creating the most durable and wear-resistant Portable that has been produced thus far. Housed inside the case is a highly efficient 500mAh battery which runs this unit for up to 5 days of continual use. We have also removed the power button so the Portable cannot be turned off accidentally in your pocket. Less moving parts, less to be concerned about.

The U1 is designed for short outings or travel between protected zones in order to keep one balanced and protected without experiencing the contrast associated with going from one protected zone to another. It is our most powerful Portable model.  The U1 is the ultimate portable protection for people who travel a lot in electric trains or who drive electric vehicles.

We recommend reading through our Blushield Product Guide to determine if the Ultra Premium Portable, or one of our other portable units, is the optimal choice for your lifestyle.

The U1 comes with its own USB charger and braided USB C cord to enable the best charge time. The U1 model is for use outside your B1 Premium Cube or Premium Ultra protected area and is not intended for use inside your home/office as a substitute for the B1 Premium Cube or Premium Ultra models.

The U1 is not water resistant and needs to be in your pocket or purse and used between protected zones, not as a stand-alone protection device. The warranty does not cover water damage or damaged power buttons from being dropped.
