FQA of Vinsic products
1.Vinsic sells a MFI USB cable - I want to know what is MFi？
Mfi, an abbreviation for Apple" Made for iOS”, is a kind of identification license for external accessories of Apple authorized accessories manufacturer based on iPhone, iPod and Pad. The certified MFI USB cables are more reliable, durable and safer. As per Apple regulation, the charging voltage of MFI USB cables connected to the terminal of iPhone should be at 4.75V-5.25V, which can effectively guarantee the voltage is not too high (to protect cell phone chips from burning), or too low (electric current can’t reach to 1A because of low voltage ).
2. Why does the Power Bank and cell phone get hot when charging？
It is normal that certain heat will be generated involving energy conversion. Small amounts of heat will be generated when charging low current equipment. Because the circuit energy is converted into heat energy, that’s why a 2000mAh mobile phone cannot be charged 3 times from a capacity of 6000mAh power bank.
3. What will help the mobile power supply when hot to not be dangerous?
For the high quality power bank, the risk coefficient is relatively small. Vinsic power bank belongs to high-quality ones, so that customers can be assured the risk is not dangerous. However, as a friendly reminder to our customers, please do not charge in the nest or bag, because these places will accumulate heat, so the temperature therefore will then rise in the mobile phone causing more chance for danger; so don’t charge when using the cell phone. In addition, charging should be avoided in the car's compartment higher temperature environment, as well as bathroom, kitchen and other wet environments; as well as not charging, and also avoid charging, in crowded places, & on a bed , so as to prevent danger.
4. Why can’t the Power Bank boot up?
As its run out of power. If you can't turn it on after receiving it, it will be because it has run out power. Please get the power adapter (output current at 1A-1.5A) and micro USB & connect to charge the Power Bank (for around 3- 5 minutes). Then try again, and recharge.
5. For a new power bank, do we need to charge 12 hours to activate it?
As we know, an old mobile phone battery used a nickel metal hydride battery (or nickel chromium batteries), these batteries having memory effect, so they must be fully activated by using long time charging in order to play with greater efficiency. But, nowadays, power banks basically use lithium batteries, with activation having been done in the factory, and so the memory effect is small. Usually, a new power bank contains about 60% power, so what we need to do is to use up all of the power, and then charge it as long as it takes to get filled and show as full. It doesn't need continuous charging.
6. What about the safety of Power Bank? What kind of chips are used in the Power Bank?
Two kinds of chips are used in the Power bank. One is an original Li-polymer battery that is more stable and safe. It has such features as: constant output voltage, intelligent current identification and current control, over-current protection, input overvoltage and current protection, all of which greatly enhance safety performance. The other is an imported 18562 chip, produced by Sanyo, Samsung, Panasonic, Sony and other well-known companies. These companies' products are tested through markets and are of high quality. You can feel comfortable to buy and use our Power Bank.
7. Will a phone be damaged by charging with the Power Bank?
The Power bank doesn't directly impact a cell phone, but can with certain USB cables. Using unverified cables may cause short circuits because of high electrical resistance, and will cause a directly detrimental impact on a phone, as it easily causes a momentary strong current. So customers are encouraged to purchase an original USB cable or MFI USB cable.
8 Which electronic devices can be charged over Power Bank? - Cell phone and tablet?
Power Bank, promoted recently, is mainly used to charge electronic devices powered by lithium-ion batteries, including most cell phones, MP3, game consoles, GPS and digital cameras. Because the output voltage of Power Bank is at 5v, it CAN'T be used to: charge digital video cameras ( whose input voltage is at 9V)，nor part of MP3's using dry battery 7, nor laptops (with input voltage at 12V-22v), nor other large current equipment. The total output current of Power Bank is at 2.1A, so the total charging current amount should be less than 2.1A. Customers can confirm current according to the charging current shows on the adapter.
9. Why can't I charge the cell phone over Power Bank?
Please test it following these steps in-order:
a. Ensure the discharge switch of Power bank is on. b. Verify if the charging connector matches the Smartphone. If not, please replace with right connector or Micro-USB (Charging and PC Connect).
c. Check if the voltage of your electronic device is at 5V.
d. Check if your electronic device has been written into the charging protection program or consult the official, or check if it can charge other electronic devices.
e. Verify if something goes wrong with the charging input port.
f. Verify if the charging IC of this electronic device breaks down and results in high charging voltage. If the alternating current can be normally charged, then the electronic device was purchased quite some time ago.
10. How to calculate the number of charges?
number of charges equals = (Power capacity of Power Bank* battery conversion efficiency* phone inner core conversion efficiency (80%))/ the capacity of mobile phone battery).
Take iPhone 6 for example:
The power capacity of Power Bank: 10000mAh
Battery of power bank conversion efficiency: 3.7V/5V
Phone inner core conversion efficiency: 80%
The capacity of iPhone6 battery: 1810 mAh
(10000mAh x 3.7V/5V*80%)/1810=3.2
So 10000mAh Power bank, the total Number of Charger of iPhone 6 is 3.2 times.
The capacity of commonly mobile phone batteries
iPhone4S:1470mAh , iPhone5: 1440mAh, iPhone5s: 1560mAh,iPhone6: 1810mAh,iPhone6 Plus：2915mAh.
Samsung GALAXY Note: 2500mAh, Samsung Galaxy Note: 3000mAh, Samsung S4/S5:2600mAh.
11. Can car chargers be used to charge a laptop?
No. The output voltage of common car chargers is at 5V, but it will need 14-18V input voltage to charge a laptop. So car chargers can’t be used to charge a laptop.
12. What is a good solar charging panel?
There are two kinds of solar cells on the market right now, that is, amorphous silicon and crystalline silicon. Crystalline silicon can be divided into polycrystalline silicon and monocrystalline silicon.
From the perspective of photoelectric conversion efficiency of these three kinds of material, monocrystalline silicon (can reach to 17%)>polycrystalline silicon (12-15%)> amorphous silicon (around 5%). Regarding solar charging panel, the higher the photoelectric conversion efficiency is, the more efficient the sun's energy converts into electricity. Vinsic solar charging panel uses the monocrystalline silicon material.
13: Why can't my solar charging panel convert sun's energy into electricity?
Direct sunlight is needed for the solar charging panel to work. Cloud, smog and shade will prevent the sun from converting into sun's energy.
