Compact three-outlet surge protector

The Tripp Lite SK30USB is a direct plug-in surge suppressor that provides three 5-15R AC outlets and two USB ports sharing 2.1A total output. It absorbs up to 540 joules of surge energy and filters EMI/RFI line noise to protect connected electronics. A green diagnostic LED confirms active protection and alerts to wiring faults before equipment is damaged. The unit is UL 1449 3rd Edition listed and RoHS compliant.

Verify your wall receptacle

Ensure the installation location has a standard NEMA 5-15P grounded outlet rated for 120V and 15A service. Confirm that the combined draw of all plugged-in equipment does not exceed the 1800W capacity of the suppressor. Check that any USB-powered devices are compatible with a shared 2.1A supply and do not require proprietary fast-charge protocols. The flat, wall-mount form factor requires a clear vertical surface without obstructions.

Plastic housing with wall-mount design suits tight

The black plastic enclosure measures 4 inches wide, 2.63 inches deep and 5.63 inches high, weighing 1.1 units. Its direct plug-in construction eliminates a separate power cord, reducing clutter behind furniture or on a bench. The three flat AC outlets accept standard North American plugs side by side. The integrated USB ports sit on the face for convenient phone or tablet charging without an extra adapter. A connected-equipment guarantee of $5000 lifetime is provided by the manufacturer.

Questions about this item

Does the SK30USB come with any cables or do I need to buy a USB cable separately?

The package contains only the surge suppressor unit itself. You will need to supply your own USB charging cables for the two 2.1 A ports.

Should I choose this 540 joule model or look for a higher rating?

The 540 joule rating covers the three AC outlets and two USB ports in a direct plug-in housing. If your equipment draws more than 1800 W or you need a longer cord, a different form factor would be required.

What does the 2.1 A USB output actually deliver when I plug in a phone and a tablet?

The two USB ports share a total of 2.1 A at 5 V, so a phone and tablet will split that current between them. The green LED confirms the surge protection is still active while charging.
