The GM 3257 OOOH 4+1 Extension Board is a 10A power strip configured with four international sockets and one master switch. It features a built-in power indicator and safety child shutters on all outlets.
The safety shutter is the feature worth understanding, because it is the one that matters in a house with small children. Inside each socket, a shutter physically blocks the live contacts until a proper plug is pushed in, applying pressure to both pins at once. A single object — a hairpin, a key, a finger — cannot reach the live parts, because it cannot open both shutters simultaneously. On an unshuttered strip lying on the floor, it can.
International sockets take the various plug types you actually own without an adapter: Indian two and three-pin, and the flat-pin plugs that arrive with imported laptops, chargers and appliances. The master switch kills all sockets together, which is genuinely useful behind a TV or desk where several devices otherwise sit on standby around the clock.

Before You Order — Know the 10A Limit
- 10A is roughly 2,300 W in total across all sockets combined, not per socket
- Do not run high-wattage appliances from it. A water heater, iron, induction hob, microwave or room heater will each approach or exceed that on their own — those need a dedicated 16A wall socket
- This strip is for electronics: laptops, chargers, routers, TVs, lamps, printers
- Never daisy-chain extension boards. Plugging one strip into another is a common cause of overheating
- Uncoil the cord fully before use — a coiled cable under load traps heat

1) What does the safety shutter actually do?
Inside each socket a shutter physically blocks the live contacts until a proper plug pushes on both pins at once. A single object like a hairpin or a key cannot open it. On a strip without shutters, it can — which is why this matters in a home with children.
2) How much can I plug into it?
It is rated 10A, roughly 2,300 W across all sockets combined. That is ample for laptops, chargers, a TV, a router and lamps. It is not enough for a heater, iron, induction hob or microwave — those belong on a dedicated 16A wall socket.
3) What are "international sockets"?
Sockets shaped to accept several plug types — Indian two and three-pin, plus the flat-pin plugs that come with many imported laptops and chargers. You do not need a separate adapter.
4) What is the master switch for?
It cuts power to every socket at once. Behind a TV or a desk, where several devices would otherwise draw standby power all day, one switch turns the lot off.
5) Can I plug this into another extension board?
No. Daisy-chaining extension boards is a common cause of overheating and fires, because the load on the first strip becomes the sum of everything downstream. Plug it directly into a wall socket.
