Portable transporter
A portable or mobile transporter was a portable or temporarily placed transporter pad that provided site-to-site transport accessibility where none previously existed. Unlike site-to-site transporters, these devices were large and bulky units. ()

History 
In 2259, in the alternate reality, John Harrison was in possession of a bulky portable transwarp beaming device, a type of portable transporter. He used it to beam himself from Earth to Qo'noS. The device itself did not beam along with Harrison, but remained behind and was found and recovered from the wreckage of his jumpship by , who identified the device and Harrison's location. ()

In 2368, a portable transporter array was installed onboard the shuttlecraft Magellan before it entered into null space, during a rescue attempt to retrieve the  passengers aboard the J'naii shuttle Taris Murn. ()

In 2371, Commander Benjamin Sisko theorized that Morka, Atul, and Bo'rak used a portable transporter to place a piece of surveillance equipment in a bulkhead. However, Constable Odo did not believe the Klingon Intelligence personnel would be seen walking through Deep Space 9's corridors with a large device such as a portable transporter. ()

In 2374, Captain Janeway and a holographic re-creation of  used a portable transport pad, referred to in this case as a "site-to-site transporter", to escape from , an interstellar pirate in the Delta Quadrant, who had stolen a number of goods from the , including the transporter. ()

Later that year, Harry Kim believed that if mobile transporters were brought to the surface of a class Y planet, enough deuterium to get Voyager "all the way to the Alpha Quadrant and back again" could be mined. ()

By the 32nd century, portable transporters were ubiquitous, and were small enough to be worn. They also had the capacity to beam themselves along with the wearer. They could beam much faster than 23rd century transporters, taking only a second for the process to complete, and were harder to trace when rematerializing underwater. ()
