In brief: The right electrical accessories depend on where you plan to use them. Indoors, a power strip with surge protection and a switch is a practical choice. Outdoors, use a splash-resistant power strip designed for outdoor conditions. Adapters and outlet strips with built-in ground-fault protection add another layer of safety. Our comparison helps you find the right products for your needs.
Your home's electrical system is the invisible backbone of modern life. But choosing power strips, outdoor power strips, and adapters can raise plenty of questions: Which options are safe and practical, and which products live up to their claims? Our 2026 comparison tackles these questions.
We looked at several types of electrical accessories, focusing on products that combine safety with everyday convenience. From a classic desk power strip to a weather-resistant option for the patio, you'll find practical buying advice here.

Indoor power strips compared
A good power strip does more than give you extra outlets. It can also help protect your electronic devices.
Surge protection: an invisible safeguard
Reliable surge protection is essential. It helps protect valuable electronics such as TVs, computers, and game consoles from voltage spikes in the power supply caused by lightning strikes or switching operations. Check the product's energy absorption rating.
Tip: Always plug a surge-protected power strip directly into a wall outlet. Avoid plugging other extension cords into it, as this can compromise the protection.
The
, a 10-outlet aluminum power strip, combines built-in surge protection with a central switch for added convenience. Its aluminum housing also helps dissipate heat.
Placement and everyday use
Where will you use the power strip? At a desk, a slim design and individual switches for each device can be useful. Behind a TV stand, look for plenty of outlets in a compact layout and a particularly low-profile design.
Outdoor power strips compared
Outdoor use calls for extra care. Moisture, dust, and UV exposure are among the biggest risks to electrical safety.
IP rating: a key safety measure
The IP rating (International Protection) indicates how well an enclosure resists dust, other solid objects, and water. For outdoor use, choose at least IP44, which protects against splashing water from any direction.
Warning: Never use an indoor power strip outdoors, even temporarily under a canopy. Condensation or a brief shower can create a life-threatening hazard.
In our comparison, the BANGKOK model
(BANGKOK) and the (TOKIO) stand out because they're designed for both indoor and outdoor use. Their sturdy construction and IP rating make them reliable choices for gardening, parties, and powering tools.
Durability and practical features
A sturdy housing that can handle an occasional knock and a cable long enough for the job are essential. Some models also come with mounting options or retractable cable reels.
Safety first: outlet strips with ground-fault protection
In damp spaces such as bathrooms, kitchens, and garden sheds, a built-in ground-fault circuit interrupter (GFCI) provides an important extra safeguard.
How a GFCI can save lives
A GFCI monitors the flow of electricity. If some of the current takes an unintended path, such as through a person's body, the device quickly shuts off the circuit. This protection can save lives.
The two-outlet units in the "Core" series, including the
, combine this essential protection with a practical flap cover. The cover helps protect the outlets when they're not in use, while keeping the GFCI easy to reach. It's a convenient option for adding protection to an existing setup.
Note: A GFCI or outlet unit of this type should always be installed by a qualified professional. Work on fixed electrical wiring is not suitable for DIYers.
Adapters in practice: When are they worth using?
Adapters such as the
offer a convenient way to connect devices with different plugs to the outlets you already have. However, adapters do have limitations.
Everyday use vs. occasional use
Basic adapters are designed for occasional use, such as when traveling. For everyday use, such as powering an imported device, a permanent solution or a higher-quality adapter with protective earth contacts (SEV) is a better choice.
These help prevent loose connections and ensure a secure fit. A two-adapter set also gives you a spare or lets you connect devices in more than one location.
Tips for assembly and installation
Even for seemingly simple jobs, such as connecting a power strip, there are a few things to keep in mind.
Use the right tools
Make sure the screw terminals on distribution boxes such as the
are tight. Loose connections can overheat. Use the right screwdriver, and always turn off the power before you start.
Check cable gauge and load capacity
Every cable and distributor has a maximum load capacity. Add up the power consumption of all connected devices (in watts), and make sure you stay within the power strip’s maximum rating. This is especially important for high-power appliances such as space heaters and coffee makers.
Buying guide: How to choose the right product
Before you buy, ask yourself these questions to find the right product for your electrical setup.
Checklist to help you decide
- Where will you use it? Indoors or outdoors? This determines the level of protection you need.
- How many devices will you connect? How many outlets do you actually need? Leave room for a few extra devices.
- What will you plug in? Do you need surge protection for sensitive electronics?
- Which features do you need? Individual switches, a master switch, or a cord reel?
- What safety features do you need? Would GFCI protection be useful or required where you plan to use it?
Once you’ve answered these questions, you can choose a product that supports safety and is built to last.
The future of electrical installation: What’s next?
Electrical installations are becoming smarter and more connected.
Smart home integration
Power outlets are increasingly becoming connected devices. Remote control, energy monitoring for each outlet, and integration with automated routines are becoming standard features. Quality construction and safety remain essential.
Sustainable materials and design
Recyclable materials and long-lasting construction are taking center stage. Products such as the aluminum power strips mentioned above and durable outdoor distributors are already leading the way. Ideally, you should only have to buy electrical equipment once.
Ultimately, the best electrical setup is one that meets your specific needs and the highest safety standards. Our comparison gives you the information you need to choose with confidence. Choose quality to help protect your home and devices for the long term.

Frequently asked questions
- What should I look for in an indoor power strip?
- Look for reliable surge protection, a separate switch for each outlet, and enough outlets for your needs. A housing made from flame-retardant material and a long, flexible cord are other signs of quality.
- What’s the difference between an indoor and outdoor distributor?
- Outdoor distributors offer more protection against splashing water and dust, as indicated by their IP rating (e.g. IP44). Their housings are weatherproof and UV-resistant to withstand direct sunlight.
- What are the benefits of a base with a built-in residual-current device?
- A built-in residual-current device (RCD) helps protect you from potentially fatal electric shocks. It detects dangerous residual currents and switches off the circuit within milliseconds. This can be especially useful in damp areas such as bathrooms or outdoors.
- Can I use an indoor distributor outdoors for a short time?
- No. Indoor distributors aren’t protected against moisture, and even splashing water or dew can cause a short circuit or electric shock. For outdoor use, choose a product specifically designed for it.
- Are adapters with a protective earth contact (SEV) better than those without one?
- Yes. Adapters made to the SEV standard (Swiss standard) have a polarized protective earth contact and are often more robustly built. They provide a secure connection and are better suited to everyday use than basic travel adapters.
