Addtam AD5110 Surge Protector Outlet Extender with 6 AC Outlets and 4 USB Ports

If you need more places to plug in and charge devices at one wall outlet, this extender combines AC sockets and USB charging in a single unit. If your priority is high-speed USB-C charging, its charging limits matter more than the number of ports.

The Addtam AD5110 has six AC outlets and four USB ports, including two USB-C ports. Its 1800-joule surge protection and widely spaced AC outlets make it suited to a desk or shared charging area.

One specific caveat: the USB-C ports are not Quick Charge 3.0 and do not support devices that require 9–22V charging.

The essentials

This outlet extender is designed for a duplex wall outlet and has a center screw to secure it. The six AC outlets are spaced 2.2 inches apart, which may make it easier to connect plugs that crowd standard, closely spaced sockets. The four USB ports let you charge compatible USB devices without using the AC outlets for their adapters.

The USB-A output is rated at up to 5V/2.4A, while USB-C is rated at up to 5V/3A. The listing specifies 125 volts, a 15 A maximum current, and 1800 joules of surge protection, it is also ETL listed. Those details help set expectations, but the USB-C limitation is relevant if a device needs a higher charging voltage.

Buyers describe the outlet and USB combination as useful for home offices and say installation is straightforward. Feedback on the fit is mixed: some find it sits securely, while others say it does not sit flush or can come loose. The included screw is intended to help hold it against a duplex outlet, so the actual fit is worth considering for your setup.

Best use cases

This design is most useful where a duplex outlet needs to serve several everyday electronics, such as a home-office desk with chargers and plugged-in equipment. The wider spacing can also help when bulky plugs would otherwise block neighboring sockets. A practical setup might use the AC outlets for a monitor, lamp, and other compatible equipment, while phones or other USB devices use the USB ports.

Unlike a basic splitter that only adds AC sockets, this one includes USB-A and USB-C charging plus a stated surge-protection rating. A separate charger or power solution may make more sense if your devices need USB-C charging above 5V or if you need a different outlet arrangement.

Who it’s for

It’s a great fit if you want to consolidate AC plugs and USB charging at a duplex outlet, and the 2.2-inch outlet spacing suits the plugs you plan to use. It may also appeal to dorm rooms or workspaces where a single wall location has to handle several everyday devices.

You may want to skip it if your USB-C device requires 9–22V charging, or if your outlet setup is not a compatible duplex receptacle. The manufacturer notes that the plastic support prong must be cut off before use with USB receptacles and GFCI outlets. Buyers’ differing reports about fit also suggest that a secure, flush installation is not guaranteed in every setup.

Before you decide

How many devices can it connect? It has six AC outlets and four USB ports. The listing describes it as able to power or charge up to ten devices at once, the devices and their power requirements still need to be compatible with the outlet’s ratings.

Does USB-C support Quick Charge 3.0? No. The listed USB-C output is up to 5V/3A, and the manufacturer says it does not support devices requiring 9–22V charging.

How is it secured to the wall outlet? It plugs into a duplex outlet, and the center screw can be used to secure it. The manufacturer also describes a plastic support prong, with a note that it must be removed for USB receptacles and GFCI outlets.

Buying verdict

Choose the AD5110 when the main need is a compact wall outlet hub with six spaced AC sockets, four USB ports, and a documented 1800-joule surge rating. Its mix of USB-A and USB-C is convenient for common charging needs, but it is not a fit for devices that require higher-voltage USB-C charging. The mixed reports on how securely it sits make the outlet’s shape and installation a meaningful part of the decision.
