If you’re looking for the best of the best EMF protection in a portable package, look no further than the Blushield U1. The U1 is a quantum leap in portable EMF protection technology, breaking through what we previously thought possible.

This is the same generation of circuit found in our Premium Ultra and Premium Cube.

We have updated the algorithm to provide the best portable protection against 5G radiation available.

The new case is precision CNC machined out of aircraft grade alloy, creating the most durable and wear resistant portable we have ever produced. Housed inside the case is a 1000 mAh battery which is the largest ever used in a portable Blushield.

Every detail, from the packaging to the durable charging cable, was built to the highest standards.

This U1 model 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. 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.

The U1 is the ultimate portable protection for people who travel a lot in electric trains or who drive electric vehicles. For protecting a large area, the Premium Cube or Premium Ultra models would be better. Check out our Premium series bundles here.

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

Notes On Charging 

This first generation U1 takes approximately 17 hours to charge from a completely dead battery, to fully charged with the final leg of the charge taking the longest.

We recommend charging your device fully before your first use and plugging it in every night or two in order to keep the battery topped off.

The U1 will run continuously for approximately 5 days on a full charge so charge your unit every couple nights for best battery results.

For faster charging, try using a 2 amp charger.
