Surge protectors are multi-socket strips and extension leads with built-in protection against voltage spikes, made for computers, TVs, network equipment and other home or office electronics. Our range has over 200 models, including ACAR, Qoltec, Lanberg, LogiLink and Brennenstuhl.
How to choose a surge protector
Number of sockets. Count everything you will plug in and leave at least one socket spare. Our range runs from 2 to 8 sockets, with most variants having 3, 4, 5 or 6. Bulky power adapters can block the socket next to them, so the spacing between sockets matters too.
Cable length. Many models have a cable of around 1.5 m, which is enough for a desk or a TV cabinet. If the wall socket is far away, look for a longer lead: we have models with 3 m and 4 m cables. Coil up any excess rather than leaving it in a heap under the desk.
Current and power. A standard household socket is rated for up to 16 A, which at 230 V is roughly 3680 W. That is the rating listed for many models in our range. It is ample for a computer and monitor, but do not plug several heaters or a kettle into the same strip.
Level of protection. Compare the surge energy rating in joules: the higher it is, the more spike energy the protector can absorb. Some models have an indicator light that shows whether the protection is still working. After a severe storm or many surges the protection wears out, so it is worth replacing.
Switch and extra features. Many models in our range have an on/off switch, which is handy when you want to cut power to a whole workstation with one press. Some models may add USB ports or protection for a network cable, so check the product description.

Frequently asked questions
How is a surge protector different from an ordinary extension lead?
An ordinary extension lead only adds sockets, while a surge protector includes a component that absorbs short voltage spikes. It guards against spikes, not against power cuts. To keep working when the power fails, you need a UPS.
Does a surge protector protect against lightning?
Not completely. It reduces the risk from spikes that travel through the mains, but it will not stop a direct lightning strike. During a storm the safest option is to unplug valuable equipment.
How many sockets do I need for a computer desk?
Usually 4 to 6 sockets are enough: computer, monitor, speakers, and a printer or router. Leave one or two spare, because the amount of equipment on a desk tends to grow over time.
Can I plug a surge protector into another extension lead?
It is better not to. Plug the protector straight into a wall socket, since a chain of extension leads increases the risk of overload and overheating. The protection may also work less well if another power strip sits in front of it.
