The Ancient and New Campbell Bar. ( The Campbell Apartment)
The Grand Central Terminal is one of the iconic landmarks of Manhattantown Midtown for a stroll through a historic site in the city. Or to stop to have lunch in one of the restaurants and fast foods that are under their brick vaults.
In the southwest corner of the station, on the Vanderbilt Avenue, there is an elegant bar, with charm and style. And remember the '20s: The Campbell. Formerly known as the Campbell Apartment. The building is a legendary New York institution that belonged to John W. Campbell, a millionaire jazz amateur who financed the Big Bands of the first decades of the 20th century and turned his private office into a living room. cocktails in 1923.
Located in the Grand Central Terminal
The Gerber Group, leader of the hotel industry that owns and operates many of the most famous bars and restaurants in the city, acquired the Campbell Apartment with the clear objective of restoring its original grandeur.
It is one of the most touristic places in New York and its visitors travel through time until the time of the Big Bands of jazz, at the beginning of the 20th century.
The magnificent restoration was carried out under the responsibility of the prestigious design and architecture studio Ingrao Inc., which managed to maintain the historic architecture of the property. He also introduced elements of contemporary design that create a refined atmosphere but at the same time warm and comfortable.
The Campbell retains details of its past that make it a unique space in New York. Very high ceilings painted by hand, a large stone fireplace, the steel safe that belonged to John W. Campbell. Also an old glass window with its original molding
Today, The Campbell offers three distinctive experiences. The main one, of course, is the bar itself. A timeless office with wooden furniture, mohair and leather in green, blue and dark red colors.
Another one of its spaces is The Campbell Palm Court, an interior room with rattan stools. It also has high coffee tables surrounded by tall palm trees and with views towards the main terminal. Finally, The Campbell Terrace is a large covered terrace with indoor plants and a large drink bar.
For this elegant and individual place, the Gerber Group made an exclusive selection of classic and modern cocktails with fresh seasonal ingredients. Also an interesting wine list and craft beers locally made.
The wide variety of drinks is complemented by a menu of sandwiches, salads, finger food, tapas and specialties such as daily menu.

The Smoky Mountains National Park is the most visited in the country, with eleven million tourists. The large forest located between North Carolina and Tennesse was once an ancient hunting place for Native Cherokee Indians. Today is a home of over a thousand Black …
Martin Cooper, manager of Motorola, made a call to, Joel Engel, of Bell Labs of AT&T on April 3, 1973, from Sixth Avenue in New York, with a prototype of Motorola DynaTac 8000X. That was a mobile phone that weighed approximately one kilo and was about 13 inches (33 cm) tall taking into account the antenna. It was the first call made from a mobile phone.
This prototype mobile phone used about ten hours to charge. Its battery had a range of just 30 minutes. Something that today is absolutely unthinkable
Although the call was made in 1973, it was only in 1984 that the cell phone was released at a cost of USD 3,995. 300,000 units were thus sold. Ameritech Mobile Communications LLC was the first company in the United States to provide mobile phone service. The development of mobile phones was the first stage in the power bank history
Alessandro Volta Battery
Alessandro Volta discovered the pile or column, which he initially called "artificial electric organ", studying the effects of galvanism on frog legs. Volta thought that what he called galvanism was an animal electric current. It was named in honor of Galvani, founder of Nervous Physiology, who established this current by joining two different metals by means of nerves or muscles of an animal. In reality, galvanic current is a direct current (d.c.).
Volta built the first stack that we can reproduce. Volta stacked discs of equal size of copper and zinc, alone or with tin, alternated, with a moistened cloth interspersed between each one. This "stack of discs" begins and ends with discs of different types. By connecting the disks at the ends with a wire, an electrical flow flowed. By impregnating the cloth with certain salts, the current obtained was much higher.
Who invented the Lithium Batteries?
A very important chapter in the history of the power bank, is who invented the lithium battery. John Goodenough invented, in 1980, the basic technology of lithium-ion batteries used in smartphones, notebooks, tablets, cameras and of course power banks. At age 97 he continues to investigate and is a professor of mechanical engineering at the University of Texas in Austin, USA (you can send an email to (email@example.com). (1) John B. Goodenough won the Nobel Prize in Chemistry in 2019 alongside M. Stanley Whittingham and Akira Yoshino for the development of lithium-ion batteries
Smartphone power banks
In 1979, Goodenough showed that by using lithium cobalt oxide as the cathode of a lithium-ion rechargeable battery, it would be possible to achieve a high density of stored energy with an anode other than metallic lithium. This discovery paved the way for the development of lithium-ion batteries, which are now in portable electronic devices and electric vehicles.
The lithium-ion battery developed by Goodenough in 1980 began to be marketed in the 1990s. Today it is the dominant battery technology for almost every portable device, including cars.
What are the advantages of the lithium battery?
Responsibility with the environment
High energy density
Optimum relation weight / Amount of Stored energy
And the disadvantages?
The most notable and dangerous danger of explosion. As has happened with Samsung's Galaxy Note 7 phones, if these types of batteries are overcharged they can explode.
Why do lithium batteries explode?
"Normally, when a power bank explodes the problem lies in the original battery used by the device. The electrolyte they used is inorganic, which is flammable. And if it charges very fast (improper charger) that overheating causes the explosion," he said Goodenough For the American chemist, the important thing is to "monitor the battery operation very carefully" and not charge the cell phone too quickly. In other words, give the battery time to dissipate the heat from the load.
Another factor to consider is the outside temperature. At higher external temperature, lower dissipation capacity and increased risk of explosion. Smartphone cases also contribute to mofify the battery dissipation. For this reason you have to choose the right case for each smarphone within those recommended by each manufacturer. (2) (3) (4)
Who Invented the First Power bank?
History of Power Bank: The Power Banks were first announced in 2001 at the Las Vegas International Consumer Electronic Show, where a student used a portable AA battery set in an electrical circuit. unfortunately we don't know the name of quin fabrico this first power bank
At the beginning of the 21st century the battery of mobile phones had a high duration. Here begins the true history of power bank. So the Power Banks did not really exist until Apple released the first iPhone in 2007. This smartphone could not easily remove the battery. In addition to this, the autonomy of continuous use of the device was 4 hours. This created the market and the demand for Power Banks.
Store the Power Bank in a place where it is not exposed to very high temperatures. If we store it in a place where it is very hot it could be degraded (internal chemical reaction), and could even explode and cause a fire.
Keep the battery charged to a maximum of 60% when it is stored. important. If it is not going to be used for a while, it will not be stored at maximum or below 20%. To extend its useful life, it is ideal to store it with a load of just over half, that is, 55% or 60%.
Check that the charger is of a voltage compatible with the input voltage of the Power Bank. It is important to charge the Power Bank with a compatible charger.
Avoid putting the device that is being charged in direct connection with the Power Bank, as it would raise the temperature of both devices. In this case the power bank degrades very quickly
It is recommended that when a smartphone is going to be charged we set the airplane mode to avoid internet connections. This way it will load faster.
The life of a power bank is measured by full charge cycles. Find out from the manufacturer how many life cycles the expected useful life is.
Solar: They are recharged through a solar panel. Recommended for camping, hiking, etc.
For cars: Ideal for when the car runs out of battery. Also known as "starters." Perfect to carry in the trunk of the car.
Custom: On them you can print your company logo and then you can give them to your customers at any event, fair or congress. There are all kinds. From the cheapest made of plastic to the most exclusive made of aluminum and with the laser printed logo.
