Fattafa's early stage
The Company was found in Hong Kong at 1979 as a venture acting on secondary market of mobile multimedia devices (photo-,video cameras etc.) Nowadays it is focused on producing batteries for mobile electronic devices.
Reasons of going to battery market. Source of rapid growth
Cell phone evolution
Cell phone evoution
Being an IC based device Cellphone is an illustrative example of the Moore's law i.e. each two years it's IC components doubles computational power (or becomes two times smaller) the beginning of XXI century a handset had just started to pretend to have some multimedia functions. Within next several years by integration audio and photo functions with main functionary (calendar, making phone calls) smart phones became a real alternative to classical media devices. Nowadays all smart phones are equipped with audio and video players, high resolution photo-video cameras, FM radio, able to communicate both via cellular link and via low-range interfaces (Bluetooth, WLAN 802.11b). Of course it has led to increasing the power consumption. For instance all this improvements has made available for users various on-line services that have a need for a large amount of data to be exchanged

Main article: Rechargeable_batteryPower source part is probably the only one that does not belong to the microelectronic industry. Efforts in electrochemistry are way behind from circuit's ones. Since the middle of 90ths all improvements in electro-chemical power sources were about reducing drawbacks but not about increasing specific energy. All the batteries for mobile phones are either of Li-ION or Lithium-ion Polymer type. Every manufactures hope very much for nano-technologies to leave this stagnation time. Last big results have been achieved by Yi Cui and colleagues using silicon nanowires as the anode of a lithium-ion battery that increases up to 10 times the volumetric charge density.
Smart phone design trend
The trend of smartphone design developing is to make the phone look more fancy and give more function to it but by not increasing the dimensions of the device because all previous time has taught a consumer that bigger means older. here is a very illustrative example of this topical question:
"When we looked at 3G, the chipsets are not quite mature, in the sense that they're
not low-enough power for what we were looking for. They were not integrated enough,
so they took up too much physical space. We cared a lot about battery life and we cared
a lot about physical size. Down the road, I'm sure some of those tradeoffs will become more
favorable towards 3G but as of now we think we made a pretty good doggone decision."Steve Jobs[2]
As you can see from a small table below, Apple included 3G support one year later but they were forced to make it at the cost of battery size.
Model Year Battery capacity iPhone 2007 1400 mA·h iPhone3G 2008 1150 mA·h iPhone3GS 2009 1219 mA·h iPhone4 2010 1420 mA·h for iPhone it is not so crucial because it has enough battery capacity to stay on-line about 12 ours but it is still enough to go in a business trip. but see HTC Desire HD as an example.
Additional capacity demand
Not the main part of smartphone holders but still a big one needs to stay on-line all day long using mobile Internet, watching movies etc. but the stock batteries can not provide it. Here is several ways to solve the problem.
- to always carry a charger in a pocket and looking for a socket
- to use a mobile phone's public charger (see an ill.)
Public charger - to use a relacement battery
- to use an extended battery
The market niche of Mugen Power is to provide last two options.
Production
In spite of big number of replacement battery manufactures, Mugen Power still stays one of the few brands which products go over all product life cycle phases Two type of products (see external links to some illustrative reviews)
- replacement battery (a high quality battery that has the same size, a bit bigger capacity and lower price then original one)
- extended battery (a high quality battery that has a several times bigger capacity and respectively bigger volume then the original one)
all the products pass the quality control and get the CE mark and satisfy the Restriction of Hazardous Substances Directive(RoHS)
