4-Outlet Surge Protector with 4 USB Ports

The Tripp Lite TLM446USBB provides four NEMA 5-15R outlets and four USB-A ports sharing 4.2 amps of charging power. It suppresses surges up to 450 joules across H-N, N-G and H-G protection modes. A 6.0 ft cord with a NEMA 5-15P plug connects to a standard 120V outlet. The metal housing measures 1.75" x 1.87" x 11.40".

Suited for Desk Setups Needing USB Charging

This unit fits home, office or light industrial workstations where a few AC devices and multiple phones or tablets charge simultaneously. The 15 amp, 1875 watt capacity handles typical desktop loads. Buyers who need more than four AC outlets or a higher joule rating for sensitive server gear should look at other models.

450 Joule Surge Suppression Rating

The AC suppression joule rating of 450 joules is the key figure that defines how much surge energy the protector can absorb before it must be replaced. It meets UL 1449 3rd Edition, UL 1363 and cUL certifications and exceeds IEEE 587 category A&B specifications. Maximum spike amperage is rated at 35500A.

Questions about this item

How do I mount the TLM446USBB and which step is often missed?

Use the keyhole slots on the metal housing to screw the unit to a wall or desk; the step people miss is leaving at least 6.0 ft of cord slack so the NEMA 5-15P plug reaches the 120 V outlet without tension.

What part of the TLM446USBB will need replacement after it absorbs surges?

The internal MOV components that provide the 450 joule rating degrade with each spike; once the protection indicator goes out the whole surge protector must be replaced because the modules are not user-serviceable.

What limit appears first when the four USB ports charge multiple tablets at once?

The four USB-A ports share a total of 4.2 A, so connecting several high-draw devices splits that current and each device charges more slowly than it would on a dedicated charger.
