Best split extension cords with USB ports

Top pick: the 12 ft split cord with 4 AC outlets and 4 USB ports (6 ft per side). The split design is the point: one short run to each side of a couch or desk instead of one lumpy strip, and the flat low-profile plug still leaves the wall outlet behind it usable. Four AC and four USB covers a laptop, lamp, phone and tablet at once.

Who the others suit:

• The 8-in-1 multi-plug splitter — if you want the outlets clustered in one block rather than split to two sides.
• The other 12 ft split cords — near-identical layouts, so pick on the plug style and cord length you need.

Check the USB wattage if you're fast-charging a tablet or laptop; these listings don't state it.
