In our old building, sockets are very rare. We have added new sockets here and there if there was already a connection there, but the bottom line is that you always have the feeling that there could be a few more.

Mainly in some places (sofa, etc.) there is no charging option for iPhone, iPad and iPad Pro. That means, I need charging ports with USB-A and USB-C.

On the left in the picture you can see a special flat plug. The normal power plug (right), which can be found on standard multiple socket outlets, protrudes significantly more from the wall (photos: Sir Apfelot).

Solution 1: Multiple plugs and USB power supply unit

Now you can of course help yourself with a multiple plug and an additional USB charger to turn one socket into several including charging options. It works, but it doesn't look good and the local “government” is reluctant to see it.

Power strip with flat plug

No matter how practical it is: Too much tangled cables are not allowed. If you still want to go this way, you can do this 3-way socket distributor with flat plug look at. I use this several times in the office and in the children's rooms so that the furniture can still be pushed close to the wall, even if the socket behind it is used. The power strip works perfectly and the plug is really super-flat. An absolute recommendation that will soon receive its own article.

If you place the power pack behind the sofa, it is advisable to attach long charging cables so that you don't always have to search for a long time to find out where the charging plugs are.

Solution 2: socket adapter with USB charging ports

With the second solution, we come directly to the device that is being tested here: A socket adapter that loops through a socket and also offers charging options with USB-A and USB-C ports.

This has the advantage that it takes up very little space and you still always have a charger available that does not require an additional power cord and does not use a socket.

The Lencent USB socket takes up hardly any space, has a looped socket and offers several USB-A and one USB-C charging ports.

My choice: the Lencent USB socket

There are different versions of these adapters from various manufacturers. I got the model from Lencent, but ultimately there are some other devices that do the same thing and don't cost more.

Why do I mention that? Because the Lencent socket is sold out right now and it is not clear whether it will be available again.

The Lencent USB socket takes up little space, so you can still use a neighboring socket completely.

The best models from my point of view

In order to provide you with a small selection, I have selected a few models that offer both USB-A and USB-C ports and do not require an additional socket, as they have an integrated socket.

But here is my list of the devices that I would recommend:

I chose the Lencent socket adapter because it provides most USB-A ports and a USB-C port.

My choice fell on the Lencent socket adapter, as it provides most of the USB-A ports and one USB-C port.

No model with USB Power Delivery available

Unfortunately, there is no model that works with the USB-C port USB Power Delivery standard could load. That would be nice to be able to charge the iPhone and iPad quickly or to be able to charge a MacBook Pro while it is in use.

According to the technical data, you only get 15 to 18 watts of output power without a USB-PD, which is a bit low compared to the almost 60 watts that a MacBook Pro needs when charging. However, if you measure what is actually queried by the MacBook, you come to about 10 watts. This means that in practice the Apple laptops will not even use the 18 watts described, but considerably less.

If you charge the MacBook via the USB-C port, you only get 10 watts of power. That's just enough for the 12-inch MacBook to charge loooooooooo much. But it is by no means enough for a MacBook Pro.

If you charge the MacBook via the USB-C port, you only get 10 watts of power. That's just enough for the 12-inch MacBook to charge loooooooooo much. But it is by no means enough for a MacBook Pro.

This is because the Apple laptops are optimized for charging with USB PD and the higher voltages associated with it. Charging a MacBook Pro with such a USB socket is completely pointless.

With the MacBook (12 inch) I tried my luck and was able to get 20 percent into the battery within 5 minutes (MacBook in sleep mode).

The USB-A ports deliver up to 3,5 amps - a value that is never achieved in practice when charging iPads and iPhones.

Standby consumption - negligible

If you are concerned about power consumption because you leave the socket adapter plugged in all the time, then you can calm down: My measuring device was able to determine just 0,1 watt standby consumption, which means that even with 24/7 use we are less than 1 cent Costs per year.

I suppose the same is true for the other models as all of these socket adapters work with electronic switch mode power supplies that use very little power when idle.

The standby power consumption of the Lencent USB socket is only approx. 0,1 watts, which is negligible in terms of billing, as the annual costs are less than one cent (photos: Sir Apfelot).

My conclusion on the USB sockets

The output power of the socket adapter is sufficient for iPhone, iPad, Kindle, Nintendo Switch and similar devices. However, if you work with laptops, you should opt for a multiple plug and a larger power supply (like the Tizi gas station or the Anker PowerPort Atom III Slim) so that the device is charged reliably.

I have the Lencent USB socket on the sofa in use and am happy that you can now supply your devices there while you surf or play - provided that the USB charging cable is long enough. We recommend charging cables with an angled plug so that you can hold the iPhone or iPad well. For example, this would be conceivable 3 meter lightning cable from mcdodo or this one 3 meter long USB-C cable from Ugreen.

A charging cable with an angled Lightning plug enables the device to be used even when it is about to be charged.

Until recently, I didn't know there were USB sockets with built-in chargers, but now I think they're pretty convenient. You can also use this as a charger when you are on vacation, since then usually several people have to charge their devices and there are often too few sockets available in holiday homes or apartments.

I am quite satisfied with the Lencent connector, only USB Power Delivery would be the icing on the cake, so that MacBooks can be supplied with power.
