Which is better for a dorm room?

Either one. Both give you 4 AC outlets and 4 USB ports on a 12 ft split cord, which covers a desk lamp, laptop, phone and monitor from one wall socket. Neither has surge protection, so add a surge strip for a desktop PC.

Is one worth more than the other?

No. Both are $35.99 at Amazon as of November 6, 2026, and the specs match. Pay more only if a listing bundles a surge protector.

Do these protect against power surges?

No. Listing A says it is designed without surge protection, and B states none. They protect against over-current, over-charge and short circuits only.

How fast do the USB ports charge?

Listing A rates total USB output at 5V/4A, about 20W shared across all four ports. A single phone charges fine; four devices at once will be slow.

Will the flat plug fit behind a sofa?

Yes. Both use a 0.31-inch flat plug at 45 degrees, which tucks behind furniture and leaves the second wall outlet free.

Can I take either on a cruise?

Listing A says it complies with major cruise line policies. Non-surge splitters like these are usually allowed, but check your line's rules since cords are sometimes restricted.

Split Extension Cord 12ft with 4 Outlets and 4 USB vs 8-in-1 Multi Plug Outlet Splitter

These are the same product under two listings: both are 12 ft split cords (6 ft per side) with 4 AC outlets, 2 USB-C and 2 USB-A ports, a 0.31-inch 45-degree flat plug, and a fire-resistant ABS shell. Both cost $35.99 at Amazon as of November 6, 2026, so there is no price reason to pick one. Buy whichever listing you can confirm ships with the 24-month warranty and the outlet count you need. Neither has surge protection, so neither belongs on a desktop PC or TV setup.
