kakahigh wall outlet extender with screw, 8 way outlets with 1680J surge protected and USB ports
Quick take
This wall-mounted extender adds serious plug capacity, turning one outlet into 8 AC outlets plus 3 USB ports (1 USB-C). It is a practical option for dorm rooms and offices where bulky chargers and adapters compete for space, but it is not meant for every outlet type, and some USB devices may charge differently.
Pros and cons
Pros
- Wall-mounted design with a screw and stabilizing rod for a more secure fit.
- 8 AC outlets with widely spaced receptacles to handle multiple bulky plugs at once.
- 3 USB ports (including 1 USB-C) and an LED indicator to show power status.
- Surge protection rated at 1680 joules and fire-resistant polycarbonate housing.
Cons
- Compatibility limitation: it is not designed for GFCI outlets or 2-prong outlet setups.
- USB charging performance can vary by device, with reports that some items did not charge.
- The unit may not look fully flush depending on the wall plate and your outlet area.
What buyers think
Buyer-review evidence points to a consistent theme: the extender is valued for adding both extra AC outlets and USB charging in a compact, wall-mounted footprint. Many comments highlight the thin, space-saving shape and the usefulness of having top and bottom outlets that do not block each other. Installation and stability are also recurring positives, especially where the screw-based attachment is used correctly. On the caution side, review evidence is limited but present for device-dependent USB charging, and there are occasional notes that the screw can loosen if the connection is not secured.
What you get: a high-capacity wall outlet extender
This model is built to solve one common problem: one wall receptacle is rarely enough when you have chargers, laptops, and appliances running at the same time. It provides a total of 8 AC outlets (4 three-prong and 4 two-prong) plus 3 USB ports (1 USB-C and 2 USB-A). There is also an LED indicator to make it easier to confirm the unit is powered.
Outlet layout and plug-friendliness
A major buying reason here is spacing. The outlets are arranged so you can plug in multiple adapters and bulkier power bricks without every plug colliding with the next one. Reviewers specifically mention the usefulness of the top and bottom arrangement, particularly for devices like lamps where the plug angle and clearance matter.
One practical note: because it mounts over a standard receptacle area, how “flush” it looks can vary with your wall plate and the outlet location. Some buyers are satisfied with the aesthetic fit, while others wanted it to cover the existing space more completely.
USB charging: convenient, but device-dependent
The USB section is a key feature for modern desk setups. With intelligent charging, it is designed to detect what is connected and deliver up to a total of 3.4A (17W). That typically works well for phones, tablets, and similar gadgets, and buyers mention it as a reliable charging hub for a small home or dorm charging station.
However, there is limited but real review evidence that not everything charges as expected, even when other devices do. If you rely on a specific accessory with strict charging requirements, it is worth planning to test it with your device mix.
Surge protection and safety build
This extender includes surge protection rated at 1680 joules, and it is intended for indoor use on 125V power systems. The housing is described as fire-resistant polycarbonate, which is a reassuring baseline for a wall-mounted, always-on setup where heat management and protection matter.
It also lists a maximum rating of 1875W for the AC outlets and 15A maximum current. In other words, it is meant for typical household and office charging loads, not heavy-duty appliances.
Installation: screw-mounted for stability
A stabilizing rod and screw design is included to help keep the extender firmly in place. Buyers generally like this approach because it reduces the “wobble” you can get with simple plug-over-the-outlet adapters. One review theme also suggests you should secure the screw properly, because looseness can lead to losing power when you unplug something.
Who it’s best for
- Students and renters who need more outlets on a single wall spot, especially for desks and bedside setups.
- People with many wall-wart chargers who want a cleaner, wall-mounted charging station.
- Home offices where you want both AC power and phone/tablet charging from the same location.
- Buyers prioritizing plug spacing and a low-profile fit over bulky power strips.
Who should avoid it
- If you have a GFCI outlet or only a 2-prong outlet setup, this extender is not designed to be compatible.
- If you need universal, guaranteed behavior for every specialty USB-powered device, be aware that USB charging can be device-dependent.
- If you plan to run high-watt appliances that exceed typical surge-protector loads, you may want a different category of power protection.
Is it worth it?
It is worth considering when you want a compact “plug expansion” solution that also includes USB charging, and you value the convenience of a wall-mounted, surge-protected setup. It becomes less appealing if outlet compatibility is uncertain (GFCI or 2-prong setups) or if your USB devices have unusual charging needs.
If you decide to buy, use the outlet type check as your first filter, then verify your device charging needs with your specific phone, tablet, and USB accessories.
Alternatives to consider
- USB power strip with surge protection: A better fit if you need compatibility with a wider range of outlet types or if you prefer a flat power strip instead of a wall-mounted adapter.
- Multi-outlet surge protector (desktop or floor): Consider this when you need flexibility for appliance spacing, or when you want to avoid any “not flush” mounting aesthetics.
- Dedicated USB wall charger + separate surge strip: If your USB needs are simple (phones only), splitting USB charging from surge protection can reduce device-dependent surprises.
