Questions about voltage, battery, ma

[ImbaWind]

I have 3 batteries :
2x 950 mAh + 1x 1150 mAh (all of them are 3.7v)
And I'm going to connect them together and make a portable recharge-able battery charger for my phone

My question is :
1. Can I charge them directly with computer USB port?
2. Can I charge my phone directly using these batteries ?

If not, what do I need?

Hmm, I think you may have to charge them seperately in your phone via USB, unless you can have the wires at the right ohms. Interesting idea though

Hmm, you might be able to use a 3rd party charging dock

1. No - Li-ion batteries have 3,7V and USB have 5V, second is Li-ion needs special charging control microprocessor - without it the can overcharge and explode, don't try it!!
2. No - you need an step-up circuit to get 5V on the output which is need to charge the phone.
