I had bought this one back in 2020 and it's still working great till this day. It's being using in my restaurant for computer and other devices everyday. Great quality. Will be repurchasing this. Highly recommend. Review: Quite a premium product and very solidly built. - I travel frequently on work and carrying a good extension board with long wire is very much necessary for me to work in hotel rooms (several hotel rooms do not have enough sockets at right place and on international travel this helps a lot for me by carrying only one AC adapter and connect it to the extension board, which helps me connect all my gadgets with their stock Indian plug) What I liked - Very well packed - Solid and very premium built quality. - The length of the wire - Quality of the wire seems very solid - should be capable of withstanding higher load than most other extension boards - Very good space between sockets - so ample amount of space to accommodate big plugs - Premium finish What could have been better I just received the product yesterday and only used it for a few hours now and I am really very satisfied. So at this point, everything seems very good.. will be able to say more, may be after using it for a few months. The only thing I am a bit skeptical is about the switch, as there is only one switch for all the sockets and it is a push button type, though the product brochure says that it can withstand upto 10,000 times on/ Off. It would have been good to have individual switches for each socket. ## Features - 100% Pure Brass Bar Inside; No Wiring Reduces Risk of Short-Circuit - 10 Ampere, 2500 Watt Rating; Suitable for Most Home Appliances (such as rice cooker, fan, refrigerator, machine and other appliance of around 220W) - 5000 Cycle Insertion Tested and 10,000 Cycle On/Off Testing - Push Button Switch with Silver Contact Point; Ensures Longer Life Against Normal Rocket Switch - Rubber coated 0.75 mm2 copper wire of three cores with 24 strands in each core (3 meter wire length) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01N9VA8ZT | | Best Sellers Rank | #95,274 in Electronics ( See Top 100 in Electronics ) #307 in Extension Cords | | Country of Origin | China | | Imported By | Ramptel Solutions Pvt Ltd, GW-06, Sector 135, Noida, UP - 201303 (Ph: 8860009345) | | Included Components | Extension Board | | Item Dimensions LxWxH | 28.6 x 6.5 x 3.2 Centimeters | | Item Weight | 480 g | | Item model number | GNIN-N1040-30 | | Manufacturer | Gongniu Group Co., Ltd., Gongniu Group Co., Ltd., East Industrial Zone, Guanhaiwei, Cixi City, Zhejiang, China | | Net Quantity | 1 Count | | Packer | Gongniu Group Co., Ltd., East Industrial Zone, Guanhaiwei, Cixi City, Zhejiang, China | | Product Dimensions | 28.6 x 6.5 x 3.22 cm; 480 g | ## Images ![- Gongniu (Formerly Bull) Extension Board; 4 Socket, 1 Switch, 3 M Wire, 250 Volts, Assorted - Image 1](https://m.media-amazon.com/images/I/41zw4pw0v1L.jpg) ![- Gongniu (Formerly Bull) Extension Board; 4 Socket, 1 Switch, 3 M Wire, 250 Volts, Assorted - Image 2](https://m.media-amazon.com/images/I/61rIYZUn7uL.jpg) ![- Gongniu (Formerly Bull) Extension Board; 4 Socket, 1 Switch, 3 M Wire, 250 Volts, Assorted - Image 3](https://m.media-amazon.com/images/I/515-yv5VEpL.jpg) ![- Gongniu (Formerly Bull) Extension Board; 4 Socket, 1 Switch, 3 M Wire, 250 Volts, Assorted - Image 4](https://m.media-amazon.com/images/I/61UgfkO3m6L.jpg) ![- Gongniu (Formerly Bull) Extension Board; 4 Socket, 1 Switch, 3 M Wire, 250 Volts, Assorted - Image 5](https://m.media-amazon.com/images/I/5111myBvJnL.jpg) ## Questions & Answers **Q: Can this be used to plug in a desktop and speakers?** A: yes we can use **Q: How can i claim warrenty if got damaged.

Worked smooth for my monitor, cpu, wifi extender together which was kept on for whole day since lot of months as working from home. 3. Length of wire is as described, long, useful. 4. Worth the cost Given 4 star and 1 star less because the plug switches are a bit close to eachother so if you are thinking to use all 4 switches it might be a bit difficult. ## Frequently Bought Together - Gongniu (Formerly Bull) Extension Board; 4 Socket, 1 Switch, 3 M Wire, 250 Volts, Assorted - GONGNIU Bull () 4 Socket Extension Board with 4 Switch and Wire | Power Extension for Home, Office | Extension Socket - GONGNIU Bull Extension Board - 5 Socket, 5 Switch, 3 M Wire | Universal Extension Socket 3M for Home, Office | Power Strip with Universal Compatibility --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/64863277-gongniu-formerly-bull-extension-board-4-socket-1-switch-3](https://www.desertcart.hk/products/64863277-gongniu-formerly-bull-extension-board-4-socket-1-switch-3) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-06-04*
