  need mo 5v 500ma yung parang cellphone charger na fast charge

• awakeruze on May 20, 2013 05:47 AM

  Kung 13-port hub, dapat at least 6 amps yung 5v adapter.
  
  Kasi bawat USB port, 0.5 amp ang maximum current.

• jonathanbersola on May 20, 2013 05:47 AM

  kaya na kaya ipower lahat yun?

• jonathanbersola on May 20, 2013 05:49 AM

  anong adapter kelangan ko? san po ako makakabili nun?

  actually power booster lang yung power plug dun may power na yun galing usb kaso hindi naman kayang supplayan lahat yan kaya may external power

• jonathanbersola on May 20, 2013 06:13 AM

  gusto ko sana kaya mag power ng external drive sa usb hub

• awakeruze on May 20, 2013 06:21 AM

  @silentorange18
  That may be so, but it's better to be safe.
  
  You can't simply assume that the USB port the hub connects to has power to spare.
  
  I stand by my suggestion.

  lahat naman ng usb hub na hindi lumalagpas sa 4 ay sa usb din kumukuha ng power

  Bawat Ext usb ay may 2 pcs usb connector para higher current ng 5V supply at signal communication. So kung may extra 2 usb port sa pc mo ay di mo kailangan ng 13 port usb port. Laki lang gastos dahil bibili ka pa ng dc 5V adapter at di mo pa sure kung ilang ampere ang available na mabili.
  
  Ano model number ng usb drive mo? Ilan usb connector meron ito? Dapat malaman mo power consumption para malaman natin at dapat piliin na power source.

  1 cable lang po from external hard drive. WD My Passport USB3.0 po. para na rin po sa controllers, bluetooth dongle, printer, mga flash drive po. 4 ports lang po kase USB ng mobo ko. Sira po kase front panel usb ports ko.

  ^ Kung sa Desktop PC mo gagamitin mga iyan. Baka mahirapan ka bumili ng +5V regulated DC adaptor na 6A capacity. Sa PC psu ka na lang kumuha ng +5V at lagyan both side ng connector para sa 13 port dc input.
  
  2 feet lang wire gamitin mo same sixe ng wire sa psu para wala masyado voltage drop sa wire.

  ayun lang. wala ko alam sa electronics sir. kala ko may pwede bilhin na power adapter para dun

• awakeruze on May 20, 2013 04:34 PM

  Sira po kase front panel usb ports ko.

  
  Palitan mo na lang yung Front USB ports mo.

• Pentium4_630 on May 20, 2013 04:36 PM

  Hanap ka na lang dc adaptor na +5V 3Amp na lang. Pero bilhin mo yun may nakasulat na +5V DC Regulated. Hwag bibili ng may selector switch pagpili ng voltage. Hindi totoong voltage regulated iyon. Kung walang load ang adapter ay abot ng +7V output nun. Sisrain yun mga usb device mo.
  
  Either bili ka ng DC regulated adaptor or pagawa ka na lang ng wire na may connector katulad ng advice ko. Na mas mura , mas safe.
