How benchmarksutra rates extension boards and surge protectors: maker-stated specs and Indian prices only, nothing guessed.
Quick Verdict
The benchmarksutra Power Strip Score rates 7 extension boards and surge protectors sold in India. Every spec comes from the maker's own product page, and every price from an Indian retailer's listing. We never use test results from other sites, and we never fill a gap with a guess.
Researched, not hands-on tested. Scores use only the specifications on each maker's own product page (checked 14 November 2026) and prices at Indian retailers (checked 14 November 2026). We did not test these extension boards and surge protectors ourselves. How the benchmarksutra Power Strip Score works.

Price. Lowest price we found, against the cheapest board in the list.
Buyer profiles
What we checked
We read each maker's own product page for sockets, USB ports, surge rating, load, cord length and warranty. Retail listings are used only for the price. Where a maker leaves something out, that row is left out and the weights re-spread. A product is ranked only if its maker states at least 4 of the 7 rated specs.
Buying safely in India
Extension boards fall under the BIS standard IS 1293 for plugs and sockets. Look for the ISI mark and the CM/L licence number on the board. Do not run an AC, geyser or room heater on a 6A board: those need a 16A socket.

What the score does not measure
How much of a real surge the board stops. That needs a lab test.
