Thank to CDR King, I now just bring with me 1 USB cable for my mobile phones and tablets.
My Starmobile Engage has a Mini USB port while my Samsung phones have a Micro USB port. With this 2-in-1 micro/mini USB cable from CDR King, i now have only one cable to bring with me and use only one USB port from my laptop.
Only the Micro USB works for data transfer. But both can be used to charge your gadgets from your laptop. I have tried using this with a USB plug (plugged in to an ordinary electric socket) and I noticed that the units heats up fast. So I quickly disconnected it. I also tried using this cable with a USB cigarette car charger, and same thing, it heats up fast. So I think its just meant for laptops – slow charging.
I also use it to charge my X-mini speaker.
This cable is only Php 100 and hard to find. I bought mine at CDR King EDSA Central Mall.
