  • 90 Degree Outlet Adapter: The innovative 90-degree design allows large wall warts and adapters to fit without blocking adjacent outlets, making this electrical outlet extender perfect for tight spaces. Note: It won’t block the other outlet, but two of these adapters cannot fit side by side on the same wall outlet.

  • Space-Saving Design: The compact 3 outlet cube tap (also known as plug splitter or power outlet splitter) is ideal for use behind furniture or in tight spaces, adding additional outlets in hotel rooms, conference rooms, or areas with limited AC receptacles.
  • Versatile Compatibility: Works with 3-prong grounded cords and 2-prong polarized electrical cords, this multi plug outlet solution is perfect for sideways AC receptacles and offers a convenient way to expand power access.
