Double Plug Adaptor 13A MSCIEN 4 AC Outlets and 3 USB Wall Extension (Black)
Product description
The essentials
A wall-friendly multi plug extension is one of those everyday fixes you don’t appreciate until you need it. This Double Plug Adaptor from MSCIEN is designed to give you more plug sockets plus built-in USB ports, while still only taking up a single wall socket. On paper, it’s aimed at home charging and powering small appliances more neatly than trailing bulky extension leads.
The pitch here is pretty clear: you get 4 AC outlets and 3 USB ports in one compact setup. That means you can charge phones or tablets and run standard devices at the same time, which is especially useful in kitchens, home offices, living rooms, or anywhere wall space is tight.
That said, it’s not a “unlimited power” solution. Multi plug adaptors always come with an upper load limit, so it’s worth being sensible about what you plug in.

Key takeaways
What stands out most is the mix of regular power sockets and USB charging. The adaptor includes three USB ports that are intended to detect charging devices and dynamically allocate current, with a maximum current of 2.4A per USB port. In real life terms, that’s the kind of feature you notice when you’ve got a phone and a tablet on charge at the same time.
It’s also built around a non-blocking, space-saving idea. Instead of needing extra space for the extension lead, the design is described as only occupying one wall socket on the panel, which can help if your wall has limited room around the sockets.


Safety measures are explicitly called out: a built-in 13A fuse, a safety door, and flame-retardant material. None of that makes it indestructible, but it does matter on a wall-mounted adaptor that’s likely to be used daily.

What it’s like to use (everyday scenarios)
If you’re working from home and your desk is a mess of chargers, this adaptor is the sort of thing that can clean things up. Picture this: you plug the adaptor into the wall, then use the USB ports for your phone and tablet, while your laptop charger or a small monitor takes one of the AC outlets. With the rest of the setup staying on the wall, you avoid adding another long lead across the floor.
In a kitchen or living room, it can play a similar role—think TV setup plus a router/smart hub and a couple of USB charges for accessories. The “single socket occupancy” angle is particularly handy where there isn’t much clearance next to the existing plug.

Where it shines (and where it may feel limited)


This is a sensible buy if you want a compact multi plug extender that covers both charging and mains power in one go. It’s especially relevant if you’re trying to avoid clutter and don’t have space for a traditional, bulky extension lead.
However, it can be the wrong move if you routinely need to power high-load appliances. The stated maximum capacity is 3250W at 250V/13A, so if you’re thinking of running heavier devices, you’ll want to double-check their wattage first. Also, the description mentions 4 AC outlets, so if you need lots of spaced-out connections (or bulky plug heads), it’s worth considering how your plugs fit physically—non-blocking helps, but layout still matters.

Buying verdict
It’s not a bad choice for day-to-day home use if you value convenience: multiple AC outlets plus USB charging, with safety features like a 13A fuse and flame-retardant material, and a design that aims to use only one wall socket.
You may want to skip it if your use case is heavy-duty or you plan to plug in higher-power appliances without checking their ratings. And if your priority is controlling or monitoring power per outlet, this description doesn’t suggest any advanced controls—so you’d likely be happier with a more feature-focused power solution.
It makes most sense for people setting up charging and everyday electronics in kitchens, offices, or living spaces—where cable tidiness and mixed charging needs are the main problem.
