Recently, Sanwa Supply, a small Japanese electrical appliance company, posted a power outlet on its crowdfunding page. The seemingly basic item, which cannot be further improved, unexpectedly received the attention of the community. The product has a unique design, helping to solve the inherent problem of conventional devices, which is that there is a hole but it cannot be plugged in.

In just a short time, Sanwa has reached the amount of money needed to commercialize the product. On the Makuake platform, the company earned 11.32 million yen ( 2 billion VND ), 740 times higher than the original goal.

With long sockets with many holes, users will take up a lot of space when installing large plugs or electronic device chargers. Therefore, even though there is still space, users are frustrated because they cannot plug more things into the power source.

With its clever design, Sanwa's socket can be inserted vertically, horizontally, or in between two holes and still work normally. The product comes with 8 holes. But each of these positions has 4 instead of the usual two slots. It can also be expanded when two adjacent holes have enough space to insert an additional plug in the middle.

In addition, the manufacturer also arranged two additional USB-A and USB-C charging positions as modern standards. It comes in two colors, black and white, with a 1.5-3 m cable option.

The company says it took them three years to come up with the initial idea. The technical problem was to arrange the contacts at twice the normal density, while still ensuring electrical safety, avoiding contact, short circuit or overheating. This socket was born to handle situations that users encounter on desks or under TV cabinets, locations that require a lot of peripheral devices and chargers.

According to the announcement, this item has received Japanese electrical safety certification. The product also prevents fire spread and lightning. The socket is currently sold on e-commerce sites for 3,600 yen (850,000 VND).

This item was shared on Reddit and was highly appreciated by many international users, praising it as a genius idea. However, its design is only suitable for countries that use the standard two-prong flat plug. The product cannot be applied in markets that use three-prong plugs. In addition, the round-pin shape, which requires more space, is also a technical challenge for Sanwa when converting.
