Can I use Kindle or Nikon camera charger to charge my SamSung S7652 Duos? I do not have the charger of this phone and used to charge it with my laptop. Can I use the Kindle Charger (output: 4,9V - 0.85A) or Nikon camera (Output: 5V - 500mA) to charge my Samsung S7652 (requires: 5V - 1A)? I tried to put the charger on and it worked but I am afraid that it may cause problem with my phone in the future. Please help. Thank you!!!
