Cell phone battery charging
« on: July 30, 2016, 08:11:16 pm »
I want to know if I can use a power bank to charge a cell phone battery directly. The output on power bank is  5v 2.1 amps... it's a nextech 8024182

Is there a curcuit I can make to go between the battery and power bank, or a step down converter maybe....???

That's called a battery charge circuit... the choice of which must be done accordingly to the battery type that you didn't mention.

I want to do this so that I can get a second spare s5 battery to charge on the go/fly, so thus I have to fully charged batteries...


Also I already have the power bank

Phone batteries aren't really meant to be swapped out regularly.  Perhaps just a portable charger?

Well I basically just wanted to know how... I guess I can just keep using the battery bank like it is

You could buy one of those universal lithium battery chargers. Their primary target is camera batteries, but if you choose one in which a (typically flat and wide) phone battery fits, I don't see why it shouldn't work... You sure don't want to hook up the battery directly to your power bank.

Samsung sell a pack with both the battery and a table chager if it might help. Had the same kit back when I had an S4.

I wonder why the ebay charger is missing its original packaging? Is defective and was returned? Factory reject? I would never buy it and risk having my home burn down.
