Home Electrical Basics: PDU vs Power Strip

Understanding the battle of PDU vs Power Strip is essential when it comes to organizing and supplying power to your devices. Both have their unique roles in managing electricity for various setups, but it's easy to mix them up or not know which suits your needs best. This article will uncover these power solutions, explaining what PDUs and power strips are, highlighting their differences, and guiding you on whether a PDU or a power strip is the right choice for your home. 

What Are PDUs and Power Strips?

PDUs, or power distribution units, and power strips are both devices that offer additional electrical outlets from a single source, essentially expanding the capability to plug in multiple devices. Power strips are commonplace in both professional and residential settings, essentially functioning as multi-outlet products, which are typically used to provide a convenient number of additional outlets and often come with surge protection. They are simple solutions when you need to plug in several devices, especially when outlet space is scarce.

On the other hand, PDUs are tailored for more complex and demanding environments such as industrial settings or data centers. They not only offer additional outlets but also come with extra features that allow for remote access, monitoring of power consumption, and efficient energy distribution to multiple devices.

What Are the Differences between a PDU and a Power Strip?

Understanding the differences between a PDU and a power strip is important for selecting the appropriate tool to meet specific power distribution needs. Some differences to note include:


  • Outlet Types:PDUs offer a wider range of outlet types, including both domestic (US Nema, UK BS1363, Schuko, etc.) and industrial-grade outlets (IEC C13 / C19). In contrast, standard power strips typically only feature domestic outlets specific to certain countries.
  • Outlet Quantity:PDUs can have anywhere from 4 to 48 outlets, accommodating the higher demand for connected devices in professional settings. Power strips, however, generally provide 2 to 8 outlets due to limitations in amperage and power quality when distributing electricity across multiple points.
  • Inlet Types and Cordset Thickness:Both PDUs and power strips support domestic inlets, but PDUs also cater to industrial-grade inlets (IEC 60309, NEMA L6-30P/20P, etc.) and offer thicker cordsets that allow for more current to be carried, reducing resistivity and improving electricity flow.
  • Inlet/Cordset Quantity:While standard power strips have a single cordset, PDUs may come with dual configurations, including Dual Feed and Automatic Transfer Switch (ATS) options, providing added power redundancy.
  • Power Phase (Voltage):Power strips typically provide 110V / 208V / 230V single-phase power suitable for homes and offices. PDUs, on the other hand, also offer 208V / 400V three-phase power, delivering more power capacity and supporting heavy workloads in industrial applications.


  • Usage Environment & Installation:PDUs are optimized for IT and data center environments, designed for power distribution to servers, network equipment, and other rack-mounted devices. They are usually mounted to server racks, in contrast to the more versatile location options for power strips.

Physical Differences

  • Form Factor and Materials:PDUs are available in both vertical (0U) and horizontal (1U / 2U) configurations, made from robust materials like steel, which is indicative of their industrial usage. Power strips usually have a bar-shaped form factor and are often constructed from plastic.

Safety and Advanced Functions

  • Safety Devices:PDUs are equipped with industrial-grade safety features such as resettable fuses or magnetic circuit breakers, and additional protective measures against power quality issues. While some advanced power strip models do incorporate basic safety features like surge protection, they lack the comprehensive protections found in PDUs.
  • Advanced Functions:Basic PDUs and power strips share similarities in providing a multitude of electric outlets, but PDUs can also include intelligent features for controlling and monitoring connected devices, adding another layer of functionality not available in standard power strips.

Should You Have a PDU or a Power Strip for Home Use?

For most home environments, a standard power strip suffices for the simple task of providing additional power outlets for common devices such as desktop computers, AV systems, lights, and kitchen gadgets. These scenarios typically do not warrant the advanced features, increased power capacity, or enhanced safety protections PDUs offer.

However, for individuals with high-end home offices, particularly those involving server equipment or other advanced tech requiring reliable, redundant power sources, a basic PDU could be a worthwhile investment. It not only ensures a stable power supply but also offers more outlets and better integration into a tech-centric setup.

If you decide that a power strip fits your home office needs, consider the Anker 727 Charging Station (GaNPrime 100W) for a sophisticated yet compact power solution. Ideal for tech-savvy professionals, this sleek device merges the functionality of multiple charging ports with advanced safety features.

Equipped with 2 USB-C and 2 USB-A ports alongside 2 AC outlets, it supports simultaneous charging for up to six devices. Its impressive 100W output can rapidly charge high-demand gadgets like a MacBook Pro 16” to 50% in just 43 minutes. Moreover, its slim profile and ActiveShield™ 2.0 technology make it not only space-efficient but also exceptionally safe for all your charging needs, whether at home or on the go. 


In conclusion, the distinction between PDU vs power strip is essential for anyone looking to manage electrical devices effectively. While a power strip often suffices for everyday household use, PDUs emerge as the go-to for complex or technology-intensive tasks. This understanding not only promotes safety but also leads to informed decisions that cater precisely to personal demands, ensuring energy distribution meets both consumer expectations and the necessities of the devices. 


Here are some commonly asked questions about the PDU vs Power Strip. 

Is a PDU safer than a Power Strip?

A PDU (Power Distribution Unit) is generally considered safer than a power strip because it is designed for managing power distribution in a more sophisticated and reliable manner in environments like data centers, where consistent power delivery and protection are critical. Unlike basic power strips, PDUs often come with features for power monitoring, remote control, and circuit protection, enhancing overall safety.

Does a PDU have Surge Protection?

Not all PDUs come with built-in surge protection. While a PDU is primarily focused on distributing power to multiple outlets, surge protection is an additional feature that some, but not all, PDUs may offer. It's important to check the specifications of the PDU to determine if it includes surge protection capabilities.

What are the different types of PDU?

There are several types of PDUs, including basic PDUs which simply distribute power; metered PDUs which also monitor the power being used; monitored PDUs that provide remote monitoring capabilities over the network; switched PDUs that allow for remote power on/off capabilities for individual outlets; and smart PDUs which offer the most comprehensive features including power monitoring, environmental monitoring, and remote control capabilities.
