This power supply is a total game-changer for keeping everything charged and organized. It has a solid number of AC outlets and multiple USB ports (including fast-charging), it is great for charging laptop, phone, tablet, and other gadgets all in one place without a mess of adapters. I use it in my shop to charge pool robots, rechargeable lights batteries for my hand tools and outdoor tools. The USB ports makes it great for charging items that come with a USB cord, no need for an adapter. The build quality is excellent—sturdy casing, decent cord length, and no overheating even with several devices running at once. I also appreciate the smart layout: the plugs are spaced far enough apart to handle bulky chargers, and the USB ports work reliably. Great for a home office, bedside setup, or travel. If you’re tired of rotating devices in and out of a wall plug, this is well worth the purchase.

Got the job done!

Size: 5 FT (2 prong plug), Color: White

This was the perfect solution. Old outlet and the single plug didn’t overly strain the wall socket. Lots of plug-ins for all our electronics and a long enough core to reach them all.
