One Switch Per Plug—or One Tower for Everything?

A four-socket strip lets you switch each appliance separately. An eight-socket tower adds three USB ports but turns everything off together. Both have two-metre leads; decide how you want to control a crowded desk.

30-second verdict

Choose the Masterplug SWSRG4210N if four sockets are enough and you want a separate switch for each appliance, a slim wall-fixable strip and no built-in USB. Choose the TESSAN B09C29CGMS tower when eight UK sockets and three USB ports are more useful than individual switching, and its upright body can sit securely on your desk. Both selected offers were new, in stock and had active Add to basket and Buy Now controls for London SW1A 1AA on 24 September 2026. Amazon sold and shipped Masterplug; TESSAN Prime sold the tower with Amazon dispatch. Neither increases the wall socket's safe current capacity. Check the current seller, delivery and load rating before buying.

Four Socket Switched Surge Extension

SWSRG4210N · white / 2m · ASIN B07XJFH54B

£9.50 new offer checked 24 Sep 2026

Each of the four shuttered sockets has its own switch, so leaving a monitor off need not turn off a router or charger on the same strip. The two-metre cable and wall-fixing option help position its slim body; power and surge indicators make status visible. The official specification confirms 220–240V operating voltage and describes a one-year product warranty plus a separate conditional connected-equipment warranty. Matching-option feedback mentions the useful cable length and separate switches. Amazon sold and shipped the checked in-stock offer to London.

Eight Socket Surge Extension Tower

Gray · 2 Meter(1 USB C) · ASIN B09C29CGMS

£24.99 new offer checked 24 Sep 2026

The tower places eight UK sockets around four sides and puts two USB-A plus one USB-C connection at the top. One top switch controls the whole tower; it cannot isolate each appliance like the Masterplug. The listing claims 13A maximum, 3,250W and 1,700J surge protection, with separate surge and ground indicator lights. These are product claims, not a guarantee against every electrical event. Gray 2 Meter(1 USB C) feedback mentions its compact shape, top switch and USB ports. The in-stock new offer was sold by TESSAN Prime, dispatched by Amazon and deliverable to London; the seller profile showed 100% positive feedback from 65 ratings over twelve months.

What we researched

We screened Amazon UK's surge-protected extension-lead results, excluding plain non-surge leads and items that did not fit this desk-power choice. Two different manufacturers' exact offers were checked: Masterplug SWSRG4210N ASIN B07XJFH54B and TESSAN's Gray 2 Meter(1 USB C) tower ASIN B09C29CGMS. The selected Masterplug listing showed 5K+ bought in the past month and 1,207 global ratings; TESSAN showed 2K+ and 3,670. Those changing counts describe the chosen listings, not UK market share or sales rank; rating totals may cover other variants. The real decision is individual AC control versus more sockets and integrated USB in a taller footprint.

Key findings

Count controls, not just sockets

Four independently switched sockets can be more useful than eight shared-control ones when the desk includes devices that must stay powered while others are turned off. TESSAN makes more sense if chargers and plugs outnumber your available sockets.

High

The cable is the same length

Both selected offers have two-metre leads. The placement difference is a slim wall-fixable strip versus a tower that needs a stable surface and vertical space; measure the safe route to your wall socket.

High

More outlets do not create more circuit capacity

Both are UK 13A leads. Electrical Safety First advises checking the combined load and never chaining one extension lead into another. A surge claim is not a substitute for those limits or for inspecting damaged cables.

Pre-purchase checklist

Confirm Masterplug SWSRG4210N white switched-and-surge ASIN B07XJFH54B or TESSAN Gray 2 Meter(1 USB C) ASIN B09C29CGMS.
List appliances that need their own switch and count AC plugs separately from USB cables.
Check a safe two-metre cable route and whether the strip can be mounted or the tower can sit securely.
Keep the combined load within the lead's 13A rating; never chain extension leads.
Look for a UK fused plug, read the indicator lights and stop using a lead with heat or cable damage.
Recheck new condition, seller, delivery, Prime eligibility and any warranty terms at checkout.

Amazon UK · matching TESSAN owner feedbackFive-star verified UK review dated 30 June 2025 marked Gray and 2 Meter(1 USB C). Feedback mentions the compact tower, switch on top and USB-A/USB-C ports as useful in a desk setup. This is about layout, not a test of surge protection.

Manufacturer exact-model specification

Masterplug · SWSRG4210N-MP product specificationOfficial SWSRG4210N-MP page confirms four individually switched shuttered sockets, 2m cable, wall fixing, power/surge indicator, 220–240V operation and BS1363-2 certification. It lists a one-year product warranty and a separate three-year connected-equipment warranty of up to £1,000, subject to terms.

Seller profile

Amazon UK · TESSAN Prime seller profileThe exact listing's seller profile identified TESSAN Prime, 100% positive feedback from 65 ratings over the prior 12 months, and the business name HONG KONG TESSAN INNOVATION LIMITED. The offer was fulfilled by Amazon; seller feedback is a trust signal, not product-safety testing.

Independent safety guidance

Electrical Safety First · extension-lead safety guidanceExtension leads must not exceed their current rating; do not chain leads. The charity recommends a UK three-pin fused plug, a reputable retailer, product registration and checking for heat, burns or cable damage. This guidance does not certify either selected product.

Method
On 24 September 2026 we used Amazon UK Best Sellers sorting only to discover candidates, then opened the exact Masterplug and TESSAN ASIN pages. We checked selected variants, new condition, active purchase controls, stock, seller, shipper and London delivery. One five-star verified review matching each variant informed the layout notes. The Masterplug exact-model page and TESSAN seller profile were checked separately; Electrical Safety First supplied general UK extension-lead guidance. We did not electrically test either product, verify TESSAN's surge-joule claim independently or assume an Amazon Prime badge from a seller name. Recent-purchase labels and aggregate ratings describe listings, not market rank. Product selection was independent of affiliate eligibility.
