How to Choose a Tower Power Strip: 6 Specs That Matter

1. Check USB-C Wattage

Don't judge a power strip's charging capability by the number of USB ports alone. Check the USB-C output wattage and charging standards.

For phones, tablets, and other USB-C devices, look for USB-C PD or PPS. A 30W USB-C PD port, for example, can provide substantially more charging power than a basic USB port.

Also check whether the advertised wattage applies to each USB-C port individually or to the combined USB output.

If most of your devices charge through USB-C, two high-output USB-C ports can be more useful than several low-power USB ports.

USB-C vs. USB-A

For a new power strip, USB-C is generally the more useful option. Newer phones, tablets, earbuds, and other devices increasingly use USB-C, while USB-A remains useful for older accessories.

A power strip with built-in USB-C charging can also reduce the number of separate chargers taking up space around your desk.

2. Check the Flame-Retardant Rating

A power strip may remain connected to the mains for hours or even days, so the material used for its housing matters.

One specification you may see is UL94 V-0, a flammability classification for plastic materials. V-0 indicates strong self-extinguishing performance under the UL94 test method.

When comparing power strips, also check:

• Flame-retardant material or rating
• Electrical safety certifications
• Rated voltage and current
• Maximum power

Both MiaoLab EU tower power strip models use a V-0 flame-retardant housing, providing the same housing material protection across the two versions.

The important point is to look at the complete product specification rather than judging a power strip by one number alone.

3. Look at Base Stability

The vertical design is one of the biggest advantages of a tower power strip, but it also makes stability important.

A tower with a stable base is less likely to move when cables are pulled from the side or when devices are plugged and unplugged frequently.

When comparing models, look for:

• A stable, well-supported base
• Anti-slip feet where available
• A design that keeps the tower upright during everyday use

This matters particularly on desks, bedside tables, shelves, and other surfaces where cables are frequently moved.

Base stability isn't an electrical safety rating, but it can make a noticeable difference to everyday usability.

4. Choose the Right Cable Length

Cable length is easy to overlook when buying a power strip online.

For many desktop setups, around 2 meters is a practical middle ground. It provides enough reach from a wall outlet to a desk without leaving excessive cable on the floor.

As a general guide:

• Under 1.5 m: may be restrictive for some desk setups
• Around 2 m: practical for many workstations
• Over 2.5 m: useful for larger layouts but creates more cable to manage

Before buying, measure the distance between your wall outlet and the intended location of the power strip.

5. Check Rated Load

For any power strip, rated load is one of the most important specifications.

European power strips may commonly be rated at 16A / 3680W for a 230V electrical system. Always stay within the manufacturer's stated limits and consider the combined power requirements of the devices you connect.

A workstation might include a:

• Monitor
• Laptop charger
• Desk lamp
• Speaker
• Phone charger
• Humidifier

When comparing products, look for clearly stated information about rated voltage, rated current, and maximum power.

A clearly stated rated load helps you understand how much electrical equipment the power strip is designed to support.

6. Look at Outlet Spacing, Not Just Outlet Count

Six outlets don't necessarily give you six usable outlets.

Large laptop chargers and bulky adapters can block neighboring sockets when outlets are packed too closely together.

When comparing a tower power strip, look at:

• Distance between outlets
• Adapter clearance
• Vertical distribution
• Whether larger plugs can be used side by side

This is one area where tower designs can have an advantage. By distributing outlets vertically, they can provide better access and spacing without taking up as much desk width.

The goal isn't simply more outlets. It's more usable outlets.

Tower or Flat Power Strip?

A tower power strip is particularly useful when you frequently access your outlets, use several bulky adapters, or have limited horizontal desk space.

A flat power strip may be better behind a TV console, underneath a fixed desk, or anywhere you want a low-profile solution that can stay hidden.

The tower shape is ultimately about access, spacing, and footprint.
