മൈക്രോമാക്സ് കാൻവാസ് 2 A110 ചാർജ്ജിങ്ങ്

Electronics

എന്റെ മൈക്രോമാക്സ് കാൻവാസ് 2 A110 ഫോണിന്റെ കൂടെ കിട്ടിയത്, ഒരു ട്രാവൽ ചാർജർ ആണു്. ഭിത്തിയിലെ സോക്കറ്റിൽ കുത്തുന്ന ഒരു ഭാഗവും, അതിൽ ഒരു USB പോർട്ടും ഉണ്ട്. ഒരു മൈക്രോ USB കേബിൾ ഉപയോഗിച്ചാണു് ചാർജ്ജിങ്ങ്.
സംശയം എന്താണെന്നു് വെച്ചാൽ, USB വഴിയുള്ള ചാർജ്ജിങ്ങ് ഭയങ്കര താമസം ആണെന്നു് പലരും പറഞ്ഞിട്ടുണ്ട്. ഇവിടെയും, അതു് തന്നെയല്ലേ നടക്കുന്നതു് (കാര്യം, ഭിത്തിയിലെ സോക്കറ്റിലാണു് കുത്തുന്നതെങ്കിലും, USB വഴിയാണല്ലോ ചാർജ്ജിങ്ങ്).

1. മേൽപറഞ്ഞ ചാർജർ കേടുവന്നാൽ ഞാൻ പുതിയതു് വാങ്ങിക്കണോ അതോ കമ്പ്യൂട്ടറിൽ നിന്നും ചാർജ് ചെയ്താൽ മതിയോ? പുതിയതു് വാങ്ങിക്കുന്നതു് കൊണ്ട് ചാർജ്ജിങ്ങ് സമയത്തിനു് എന്തെങ്കിലും വ്യത്യാസമുണ്ടോ??

2. ചാർജറിന്റെ പുറത്തു് എഴുതിയിരിക്കുന്നതു് 5V,1A എന്നാണു്. ഇതു്, ആ USB കേബിളിലൂടെ കയറിയിറങ്ങി വരുമ്പോൾ, കറണ്ടിനു് കുറവു് സംഭവിക്കില്ലേ?

3. ഒരു USB പോർട്ടിന്റെ ഔട്ട്പുട്ട് സ്പെസിഫിക്കേഷൻസ് എന്താണു്?

    USB based charging has advantage over a regular charger because it is a A trickle charger ie , it charges the battery using very low current which is good your battery . I don’t have much high opinion about the travel charger which you mentioned . Most of that products are not creating the right voltage and current and in turn damaging to your equipment. So either go for a regular charger or a usb cable based charger ( which is the one I recommend ) .

    regarding the question of similarity in charging using travel charger and system based charging , the travel charger will just act like a normal charger irrespective of the fact that you are plugging a USB type connector. The same cable when you are plugging to the system will deliver the power provided by the USB port of the system which will A trickle charge the mobile .

    by the way how is your user experience of Canvas 2 ?

      Ok. Thanks a lot. So I will stick with using my system for charging.

      Canvas is a good phone. I have not experienced any big issues or problems with it. The two drawbacks I felt are (അല്ലെങ്കിലും ആദ്യം നമ്മൾ കണ്ടുപിടിക്കുക കുറ്റവും കുറവും ആണല്ലോ )
      1. The 8 MP camera is not at all up to the mark
      2. No default Malayalam suport, and no Cyanogenmode support ( 🙂 )
      3. Battery, even though provides a good duration of life, takes comparitively more time to charge.

    Regarding your question on charging specification of USB port ,

    charging port supplies up to 500 mA at 5 V, up to the rated current at 3.6 V or more, and drop its output voltage if the portable device attempts to draw more than the rated current. The charger port may shut down if the load is too high. Source : Wikipedia

    If you want to charge faster go for a high Amp charger such as 3A usb charger. Such chargers are available in market. normal car chargers are 1A and apple are 2.1A and Unstandardised chargers come in different variants from 500Ma onwards, Read the out put spec before you buy a charger

    Hello there,

    Point No.1
    Your charging cable may look like a USB or otherwise, the charge voltage and current is a matter of the AC/DC adapter (the box) at the beginning end of it. So, the adapter may be supplying typically a constant voltage, say 5.0 Volt or 5.0 Volt or any constant voltage between them.
    (This voltage may be different for different phones and their adapters. For eg: the HTC phone adapters I have, uses typically 5.0 V capable of delivering up to 1.0 A. One HP Tablet (Touchpad) I have, uses a 5.3 V 2.o A adapter.)

    When you use such adapter/USB cable set to charge a phone, the charging rate is much faster. The adapter is able to deliver a higher current than it will from a COMPUTER USB PORT.

    Usually, USB ports of a computer/notebook are readily available power supply sockets too. However, their maximum output current is limited by 0.5 A (500mA) by design. At this rate, a phone will take much more time to charge up. However, it is much safer because the computer port outputs are almost always accurately 5.0 Volt, electrically more reliable and short-circuit protected. You may also use a USB port from a battery-charged notebook even when the main power is not available or during travel.

    In the scenario given above, you can use the adapter+USB Cable from a main plug and charge the phone faster or use just the cable (without adapter) from a notebook PC to charge much slower but safer.

    Many off-the-shelf cheap adapters may have slightly different voltages despite the rating they show on the label. If not designed well, they may also have lots of harmonics and noise. However, I would not say “Made in China” directly means bad quality. It is a matter of ‘make’ and ‘cost’.

    Some manufacturers may provide a special cable, that looks like a USB cable but with extra wires inside. HP is notorius for this. So when you find a replaced cable does not work, check if it is a ‘special cable’ (through a web search) before judging that the adapter has turned faulty. Same applicable for Notebook PC adapters themselves too.
