LinkTronix's original offering opened on October 1, 2021 and was completed on December 1, 2021. Except for the Updates section which may contain more recent information, the information on this page was accurate as of December 1, 2021.


LinkTronix has developed a magnetic smart outlet that can significantly reduce electrical injuries, save energy, and improve the daily lives of consumers.


The wall outlet has not evolved in over a century. Yesterday's outlet is an exposed electrical hazard that can cause unintended injury. The existing, outdated outlet has limited ability to stop/restrict the flow of electricity.

Aligning the elongated prongs to fit perfectly into the outlet is hardly ideal. Think of all the hard to reach spots in a household that regularly obstruct your path. Everyday items such as:

  • Entertainment center
  • Nightstand
  • Couch
  • Work bench

Current safety outlet covers can easily become lost and are inconvenient to replace after continual use. Most appliances consume excess energy while being plugged in and not in use!

Outdated & Lack of Safety

Electrical Safety Foundation International reported that there are approximately 2400 children a year treated in the ER for injuries pertaining to electrical outlets.

The electrical outlet and connection has had very limited development in nearly a century. There are not enough safety mechanisms to prevent unnecessary harm and risk from exposed electrical connections. With limited advanced safety mechanisms, any simple protrusion can be inserted into existing outlets and cause an undesired result.

National Fire Protection Agency (NFPA) reported:


Inconvenient & Inefficient

Households have many outlets, with many being in inconvenient locations. Behind couches, entertainment units, under desks, and high up on walls. Aligning the prongs in these situations can be difficult and frustrating.

Current outlets draw unnecessary power to idle devices. Wasting energy, taking money right out of your pocket. Why are smart capabilities limited to only a few products?

The Department of Energy states that 10% of your power bill is considered wasted energy. All those devices or appliances plugged in that are not being utilized still draw energy!

Yesterday’s Outlets

  • Higher risk for injury/death
  • Inconvenient to use
  • Can only be used manually as user plugs in/out
  • Bulky, difficulty aligning prongs
  • Consumes excess energy, costing homeowners money
“Almost all electrical injuries are accidental and often, preventable.”
- National Center for Biotechnology Information

- Million Insights


Total Housing Units in the U.S.

  • Reonomy, a leading provider of commercial real estate insights, estimates there are 58 million commercial properties across the U.S. The U.S. Census reports there are 140 million housing units, totaling 198 million total spaces between the two!
  • A 2019 report from Statista revealed there are about 9.2 million family households with children between three and five years of age living in the household.

LinkTronix has a tremendous opportunity to provide an innovative product to a wide array of demographics. From elderly people with dexterity issues to young families with children, our goal is to provide an innovative, safe solution. Protect people, improve the efficiency of daily tasks, and save hard earned money.

Price Points

Outlets vary in price, ranging anywhere from $3-$75+, depending on several factors:

  • Number of prongs
  • Volts & Amps
  • Smart-outlet features
  • Child-safety options

We aim to position ourselves competitively in the market. Many people, families, and businesses could benefit from LinkTronix. Our goal is to make our Magnetic Wall Outlet accessible to the masses.
