Do you think an ordinary power strip is enough to protect your equipment? Think again. During a storm or a power surge, only a surge protector can genuinely limit the damage. In this comparison, we have selected the best models to keep your electronic devices safe at home or in the office.
The best surge protectors pour la rentrée 2026
1. Belkin BSV604: the surge-protected power strip for every use
The Belkin BSV604 is for users who want lasting protection for electronic equipment without giving up convenience. Designed for a home or office environment, it combines generous connectivity—6 mains sockets and 2 USB ports—with 650 joules of electrical protection. Its format fits easily beneath a desk or behind a TV unit, while its two-metre power cable keeps it accessible.
Its surge-protection system acts as a barrier against instability on the electrical network. Able to absorb up to 650 joules, it limits voltage spikes that can damage computers, televisions, consoles or network equipment. The six mains sockets are complemented by two USB ports for charging smartphones and accessories without taking up the main outlets.

2. Belkin BSV603ca2M: an affordable surge-protected power strip
More compact than the other products in the range, the Belkin BSV603ca2M is the entry-level model dedicated to surge protection. With its 6 protected outlets and discreet format, it naturally fits beneath a desk, behind a media cabinet or in a work corner.
Despite its entry-level positioning, it does not overlook the essentials. Its internal system can absorb up to 650 joules, a suitable rating for common disturbances on a domestic electrical network. By diverting excess voltage to earth, it helps preserve computers, gaming routers, consoles and other audio-video equipment.

How does a surge protector work?
A surge protector constantly monitors the electricity flowing through your installation. Under normal conditions it stays out of the way; when a storm-related surge, abrupt outage or unstable grid occurs, it reacts almost instantly. Even a brief surge can permanently damage sensitive electronic components.
Absorbing and diverting excess voltage
At the heart of the system is the metal-oxide varistor (MOV), which acts as a discharge path:
- Under normal conditions, it does not conduct electricity.
- When a spike exceeds a critical threshold of around 250 to 300 volts, it becomes conductive.
- It redirects excess current to earth so that it does not reach connected equipment.
Thermal protection and user safety
Additional devices such as a fuse or thermal cut-out disconnect the power if the varistor is under excessive stress. This limits overheating and internal damage. Many models also include an indicator light: because the varistor gradually wears down as it absorbs surges, that light helps identify when the surge protector needs replacing.
