Desk power strip: space for adapters, a cable, and convenient access

A good desk power strip fits the plugs you actually use, reaches the wall outlet along your chosen route, and keeps frequently used sockets accessible. The number of sockets is the starting point for your choice. The shape of the adapters, the orientation of the sockets, and the position of the housing determine how conveniently you can use those sockets every day.

For a workspace that you rearrange or move, a standalone power strip is a practical starting point. You can plan its position alongside your laptop, monitor, and desk lamp without choosing a furniture module for installation. In the power strips section, first look for a version that suits your specific desk layout.

Start with the plugs you already have

Place the power adapters for the devices you’ll use at the same time in front of you. One power supply may be wide, another long, and a third may have a cable that exits in an inconvenient direction for the chosen location. Counting them is useful, but looking at their shape is just as important.

Sort them by daily use: which ones stay plugged in all the time, and which ones do you connect only occasionally? If you often take your laptop with you, its socket deserves a more convenient position than the one for a monitor that stays plugged in. This way, your choice of housing is linked to how you work, rather than just the number of sockets you want.

The BACHMANN CONNECT LINE B420.0012 power strip is specified as having four earthed sockets with a 35° orientation. The angle is useful information when considering plug placement. However, it does not confirm that four adapters of any size can be used at the same time. To assess this, also compare their dimensions with the housing.

Two-meter cable - along the actual route

Measure the route from the wall outlet to the planned position of the power strip. If the cable will run behind a cabinet or along the edge of the desk, include that route in your measurement. The straight-line distance across the room may seem sufficient but may not match the layout you want to achieve.

For the B420.0012, the manufacturer specifies a 2 m power cable, H05VV-F 3G1.5 mm². The catalog listing for the CONNECT LINE B420.0021 also specifies a 2 m cable. So cable length alone does not determine the choice between these two options; if your route requires something different, look for a suitable version at this stage.

The dimensions of the B420.0012 are 311 × 53 × 52 mm. This gives you a specific basis for assessing the space beside or under the desk. Also allow for space above the housing for the included adapters and for their cables to exit. The size of the empty power strip does not describe the total space the setup will occupy.

A switch, USB, and protection are different features

A power switch is convenient if you want to control the connected equipment all at once. When arranging the setup, decide whether it will be easy to reach. If the housing is hidden behind furniture, having a button listed in the description won’t by itself make it convenient to use every day.

For the B420.0012, the official product table specifies an on/off switch and no surge protection. The CONNECT LINE family includes various models and optional features. Check the specifications for the relevant reference: a series feature should not automatically be assumed to apply to every model in it.

The catalog lists CONNECT LINE B420.0021 with five 2P+E outlets, a switch, and two USB-A ports. This is a different configuration from the four outlets on the B420.0012. If USB is why you prefer this option, check the charging port specifications against your devices separately. Their presence is enough to compare the configurations, but not to promise a particular charging speed.

What the choice looks like for one workstation

Consider a desk with a monitor, laptop power supply, and lamp, to which you sometimes add a charger. For this setup, first check the four physical plugs. If the laptop adapter is bulky, how they fit together matters more than the nominal number of outlets. Next, check the cable length along the route and the space for the housing itself.

Someone else might prefer USB ports for a separate device and leave the outlets for other power supplies. In that case, the USB option is worth comparing, but only if its charging specifications are suitable. That’s a specific need, not a reason to equip every desk with the most ports.

What to include in your brief

• List the devices used at the same time and the shape of their power plugs.
• Measure the route to the wall outlet and the space for the housing with the adapters plugged in.
• Need for an accessible master switch, USB ports, or specifically stated protection.
• Confirm the permitted total load and conditions of use in the documentation for the selected model.

If you’re comparing more office setups, also consider Legrand power strips and adapters for the same requirements. Keep your priorities in mind: enough usable outlets, a cable that reaches, and access where you need it. A well-organized desk starts with the right layout, rather than yet another rearrangement of adapters.
