Best Surge Protector for Home Electronics: 2025 Expert Review
Oli
owner of OR Electrics & 18th Edition Electrician
Most homeowners in Leeds, especially those in older properties with limited wall sockets, rely heavily on extension leads. But there is a massive difference between a cheap plastic multi-plug and a proper surge protector. The former just adds sockets; the latter sacrifices itself to save your expensive TV, PC, or gaming console from voltage spikes.
Electrical faults aren't just about nuisance tripping; they can fry sensitive circuit boards in milliseconds. While a surge protector won't fix a wiring fault in your consumer unit—that's a job for me—it acts as a vital goalkeeper for your appliances against grid fluctuations and switching surges.
In this review, I've looked at three options that offer genuine protection. I've categorised them by budget value, build quality, and clever design solutions for messy cables.

Specs vs. The Real World
The Spec: "Joule Rating (e.g., 900J)"
"The higher the number, the more energy the device can absorb before failing."
This is true, but protection degrades over time. Just because the light is on doesn't mean it's working at 100%. If you take a big hit, the unit sacrifices itself and needs replacing immediately.
The Spec: "Lighting Strike Protection"
"Marketing suggests these devices protect against lightning strikes."
No plug-in device can stop a direct lightning strike—the voltage is too high. These are designed for grid switching surges and internal spikes. For lightning, you need Type 1 SPD installed at the consumer unit.
My Top 3 Recommendations
Three options to cover different needs and budgets
POWSAF Extension Lead with 4 USB Slots (3.4A, 1 Type C and 3 USB-A Ports)
POWSAF
This is a solid option for student digs or bedrooms where you have loads of low-power gadgets to charge. With 8 sockets and 4 USB ports, it solves the 'not enough sockets' problem effectively without breaking the bank.
The Good
- Huge capacity with 8 plugs and 4 USB slots
- Includes USB-C port which is becoming standard
- Wide spacing allows for chunkier adapters
The Bad
- Can encourage overloading if high-draw appliances (heaters, kettles) are plugged in together
- Build feels a bit lighter/plasticky compared to premium brands
Installer Tip:
With 8 sockets, it is very easy to overload the single wall socket this connects to. Never plug heaters, kettles, or washing machines into this. It's strictly for TV, internet, lamps, and chargers.

BESTEK
BESTEK makes serious kit. The individually switched sockets are a massive safety feature, allowing you to isolate appliances without unplugging them. The 900J rating offers substantial protection for expensive PC setups or home cinema systems.
The Good
- Individual switches allow you to isolate power vampires easily
- High 900J surge protection suitable for expensive electronics
- Wall-mountable design helps keep floors tidy
The Bad
- Significantly more expensive than standard leads
- The switches can be fiddly if you have large hands
Installer Tip:
The individual switches are brilliant for basic fault finding. If your RCD trips, you can turn off all switches on this lead, reset the RCD, and switch them on one by one to see which appliance is causing the fault.

Anker
If you are tight on space—common in Leeds back-to-backs—this tower design is a lifesaver. It keeps cables organised vertically rather than sprawling across the floor. Anker's charging tech is also top-tier for protecting phone batteries.
The Good
- Tower design saves significant floor space
- 20W PD fast charging eliminates the need for extra phone bricks
- Anker's build quality and internal safety shutters are excellent
The Bad
- Can become top-heavy/unstable if heavy plugs are all on one side
- Not wall mountable
Installer Tip:
Use this on a desk or solid table rather than the floor. Position it so the cable has slack; tension on the main flex can pull the tower over, which is a nuisance and potential hazard.
