My micro-usb port on my phone is no longer functioning. So instead of buying a new phone or waiting weeks for a cheap battery power bank to come in from China (stuck for cash), I was thinking of making my own.
I have this Anker multi-port charger here
I noticed it is certified safe, but I'm not entirely sure what this implies:
"Certified Safe: Anker's MultiProtect safety system ensures complete protection for you and your devices. Worldwide 100-240 volt AC input voltage."
Now, if I was to plug a usb cable into this power source, snip it, and connect the appropriate wires to their respective +/- connections on the battery, will it charge up safely?
Assuming I don't let the cables touch, and I do everything right etc.
I saw this done on the internet but saw a comment saying that the battery will over-charge which is not healthy for the battery.
But I was thinking maybe this Anker "intelligent" multi-port power source would eliminate this problem.
What do you think? Thanks for any answers!
(Really don't want to have to buy a new phone or battery bank)
