Common Sense of First Use Mobile Power Bank

    Mobile phones have become a must-have product for mnost people, the power bank can not only charge the phone, you can also charge flat, and notebook,
but there are a large number of people do not know how to use mobile power bank, this essay give a simple introduction about how to use it and something we have to take care.
     1,About Accessories or plugs
In order to adapt to  charge a variety of mobile phones, so most  mobile power bank are equipped with a common connector like Mini,Nokia,Samsung,Ihone4,Iphone5 etc connectors.
Now some mobile power in order to save costs, but also provide environmental protection, generally only configure the MINI, If you buy mobile power to charge Apple may need to purchase additional data cable or adapter. In addition, we must pay attention to, Apple phone using the 5V voltage, we must look at whether the mobile power support or matching voltage.

     2,The first time of use power bank
Mobile power bank for the first time, somewhat similar to the battery. In general, the purchase of mobile power, if it is formal channels of products, generally have some power, please use until battery die out.
After tIf use of finished again on the line. No need for continuous light, and then filled three times to activate the mobile power bank. The reason is that mobile power batteries in the factory,
after aseries of processes, in fact, has done this! Here to say, this must be a regular battery manufacturers of products, only then, if the roadside Make a sign what handmade battery, it does not fly.

   3, the mobile power supply maintenanceMobile power maintenance is divided into two cases, one is continuous use, the general approach is to fill the phone after the charge, until the
light is generally about 95%, in fact, qualified one  to protect the over-discharge, so you can look at the mobile power data, can no longer recharge. At this time and then access
220V or USB for charging. Tips when a re-charge out. Because lithium battery charge and discharge is a cycle, every high voltage charge once, it is equal to reduce the lithium battery life. The current
industry lithium battery, the number of standard charge and discharge is 400-500 times. The figure just for reference not fixed.
As for the charge-discharge 1000-3000 times, it is purely nonsense, not credible. Because the lithium battery charge and discharge to this data, the performance of consumption as early as finished.
The other is not saved. It is recommended to fully charged to 80% or so, you can place the dark dry place for storage, cut into the place where moisture is relatively wet, so the capacity to increase
the capacity of mobile power self-discharge opportunities, loss performance.
Mobile power for the first time common sense

     Today, with the popularity of mobile phones, tablet PCs, digital cameras, MP3 and MP4, and so on a variety of digital products, people's lives colorful, but when we are talking about phone Xing,
phone power off; To see the beauty of non-stop shooting, the camera off the power off; boring to work on the bus to listen to music, MP3 no electricity ... .... Yes, all digital products have a
common problem: the battery is not to force. Mobile power came into being, mobile power bank from last year with the outbreak of iPhone4 so far, less than six months, with lightning speed, quickly
applied to a variety of digital products. Xiaobian today to introduce the first mobile power how to charge?

Many ordinary users can not help their friends love to buy a mobile power, but do not know how the mobile power the first charge, in fact, mobile power to buy back, generally have about60% of electricity,and so exhausted Charge, as the charging method, do not need to charge the new phone as before, as the first three times to be filled with 24 hours to activate the battery.
The mobile power supply needs to be fully charged for the first time because the mobile power supply cell is fully activated at the factory.


Mobile power safety tips: Note that as far as possible when charging mobile power placed in easy to heat the place, remember not to be placed in bed.

Basic Knowledge Of USB Drive Easily Neglect By People

There are still some clients still could not get very familiar with USB combination,today DBH promo engineers team present some basic knowledge about USB Flash Drive.

A USB Stick usually made of housing case,Nand Flash,PCBA and some components and parts.The most important part of USB is Nand Flash,which occupy most cost of a finished USB drive,which responsible for store data.The flash market price greatly affect the USB price finally.

Flash at moment DBHpromo usually adopt Samsung,Sandisk,Micron,Toshiba,Hynix name brand,in actual production,we will adopt one of the chip types based on inventory.

Flash is divided into two types,one is SLC(Single Level Cell) and MLC(Multi-Level Cell),let's see what is difference between this:
Theoretical lifetime:SLC  100k times plug and play,MLC is 10K times
Speed:Usually the same capacity,SLC is faster than MLC
Power Consumption:Under same condition,SLC is lower than MLC
From oversee,the MLC not seems good than SLC,but unit cell store MLC have absolute advantage than SLC,recent years so many chip factory greatly improved the con-structure of MLC,the whole performance seems better and better.

  Another important information is about the controller of the USB,main have Chipsbank,Alcor,SMI,PHISON,Usbest etc,
SMI and PHISON belongs to USB3.0 usually do,2.0 usually adopt Alcor and chipsbank.

Usually if clients need to specific controller and chips,the cost will increase,because this add the time to find the chips matching the controller.

Why a 32GB USB drive memory size NOT have 32GB size ??

Recently lots of clients have a query toward why I bur the USB drive,the capacity not full,is this a fake USB or bad one?
Today,we ask our engineers team to answers this questions below:
Firstly,we have to say this a normal phenomenon and meet the USB stdandards.Main reason is the Binary system and decimal system caused.
1.USB factory adopt binary system:
    1TB=10^3 GB=1000G

    1GB=10^3 MB=1000MB

    1MB=10^3 KB=1000KB

    1KB=10^3 Byte=1000Byte
   
 2.Windows system adopt decimal system
    1TB=2^10 GB=1024G

    1GB=2^10 MB=1024MB

    1MB=2^10 KB=1024KB

    1KB=2^10 Byte=1024Byte
 Based on this system,a 32GB drive actual size should be 32*1000/1024=31.25G,but in actual production process,different factory,the standard is little
 various,in general,if the USB actual size above 90% of the labeling size is good product that meet the USB quality standards.

 DBHpromo USB standards as below for reference:
 Memory size  &  Actual available capacity
 128MB            >120MB
 256MB            >245MB
 1GB              >958MB
 2GB              >1.78GB
 4GB              >3.74GB
 8GB              >7.46GB
 16GB             >14.78GB
 32GB             >29.5GB
 64GB             >58GB
 128GB            >116GB
 Usual speed(USB 2.0 port)
 128MB to 16GB
