The fuel cell of the United States is a small battery that can charge more than ten times.

Brookstone, a US retailer, is known for its unique design novelties and products that are hard to find on the market. Recently they announced that they will sell a new type of portable fuel cell that can fully charge your smartphone more than ten times, used for up to two weeks.

The battery was developed by fuel cell maker Lilliputian Systems, which today announced that Brookstone will be its first retailer.

It comes with a USB port that can charge any device that supports the USB cable, and its size is close to that of a thicker smartphone. The size of the fuel cartridge is comparable to that of a lighter. Although it is still unclear about its pricing, it can be understood that its fuel cartridge is a plastic casing with butane, costing only a few dollars, "similar to the price of Starbucks coffee." Vice President of Business Development, MouliRamani said that the product will also be tested by users, and it is expected that the specific release date will be announced later this year.

People can purchase boxed fuel and fuel cells online through the Brookstone catalog, or go to the store to buy boxes. After the fuel is used up, the fuel cartridge can be recovered through the municipal recycling program.

LilliputianSystems is a spin-off company from the Massachusetts Institute of Technology. It has a history of ten years. The successful development of this battery is a huge advancement in the company's portable fuel cell technology. Several fuel cell companies are developing portable power systems, but most of them have failed.

"The problem with equipment before is that they usually use methanol or sodium borohydride as fuel, but when made into actual products, their properties are better than lithium-ion batteries." Ramani said that the fuel cell of the residents of the country is using a box. The fuel can be fully charged 10 to 14 times for an iPhone 4. For many people, a box of fuel can be used for two weeks. Ramani points out that the small country is the first to place a solid oxide fuel cell membrane in silicon. In order to produce a special silicon chip for the film printing of the villain, Intel has already modified a fab in Massachusetts.

‘’Xiaorenguo’’ expects that the first customers of batteries will be early technicians. Their portable and charging capabilities will attract more people and spend a lot of time on portable game consoles such as travelers, college students and teenagers. Ramani said: "All those who want to liberate themselves from the use of wall outlets will love this fuel cell."

The battery's boxed fuel will be produced by the lighter manufacturer and can be carried on the aircraft. Currently, ’’ Xiaorenguo’’  is looking for other retailers to build a wider distribution channel. The editor believes that compared with the almost all-colored lithium-ion battery on the market, the fuel supply capacity of Xiaorenguo's fuel cell is much stronger than that of the same volume of lithium-ion battery; the lithium-ion battery is just a "power storage station", charging electricity. In the process of storage and discharge, there is also the problem of power loss and battery capacity attenuation. The fuel cell is a “power plant”. After the fuel is exhausted, it is only necessary to replace the fuel cartridge, which is a more efficient and reliable mobile power device.
