Addtam Surge Protector Outlet Extender 1800J
Product description
A basic splitter adds outlets, while this Addtam wall extender also provides USB charging and surge protection. That combination suits a desk or dorm room where several small devices need a place to plug in.
Its six AC outlets are spaced for roomier connections, and four USB ports keep charging bricks off the outlet. The trade-off is that USB-C output tops out at 20W on one port.

For a shared desk, you could plug in a lamp and other everyday equipment while charging a phone and Kindle over USB. It suits you if you want fewer separate chargers around one wall outlet.
Technical details

The extender has six AC outlets and four USB ports: two USB-A and two USB-C. The six outlets are spaced 2.2 inches apart, which gives plugs more room than a tightly packed splitter. Its three-sided layout distributes the outlets around the unit.


The stated surge-absorption capacity is 1800J. Addtam describes a three-level protection circuit using TVS, MOV and GDT components. The housing is fire-resistant ABS, and the product is ETL certified. A removable screw and plastic prong are included to help secure it to an outlet.

USB-A is rated up to 5V/2.4A. USB-C1 supports up to 5V/3A, 9V/2.22A or 12V/1.67A, USB-C2 supports up to 5V/3A. The listed maximum charging output applies when using a single USB port, so don’t assume that each port can deliver its individual maximum when several devices are connected.
Compatibility and requirements

The USB ports are described as suitable for Kindle and most USB devices. That’s useful for phones, e-readers and other modest charging needs, but the listed USB-C1 output is 20W at its highest stated setting. If you need more USB-C power for a particular device, check that device’s charging requirements first.
This is a wall outlet extender, not a portable power bar with a cord. Its fit also depends on the outlet location and the space around it, the product details don’t give dimensions for the body, so there’s no basis to assume it will clear every nearby obstruction.



Usage tips
Use the wider spacing to separate plugs that would crowd a standard splitter, then reserve the USB ports for smaller electronics. For example, an e-reader and phone can charge directly from USB while other equipment uses the AC outlets. For the strongest stated USB charging rate, connect one device to one USB port rather than relying on several ports to share that maximum.

The screw and plastic prong are intended to help keep the extender attached. Make sure the unit is seated securely and that the surrounding wall area leaves room for its three-sided arrangement. Its 1800J rating is a surge-absorption figure, not a promise that every connected device will be protected in every event.
Before you decide
This setup is more useful than a plain multi-outlet splitter when you also want built-in USB charging and wider spacing between AC outlets. A corded power bar may suit a desk better if the wall receptacle is inconveniently placed or you need outlets farther away. Given its design, the Addtam is best considered for adding connections at the wall, not extending power across a room.


It may not be the best choice if your devices need USB-C charging above the listed 20W maximum, or if you need dimensions to confirm clearance before buying. The product information also doesn’t specify a total shared USB output when multiple devices are charging together.
Before buying
Can all four USB ports deliver their maximum output at once? The listing says the maximum power can be reached when using a single USB port, it doesn’t provide a combined output figure for simultaneous charging.
What does the 1800J rating describe? It is the stated energy-absorption capacity of the surge protector, not a guarantee against every electrical event.
Is it suitable for a Kindle? Kindle is specifically mentioned, along with most USB devices. Check your device’s charging requirements if its power needs are higher than the listed USB outputs.
