If I had a 12V 7Ah NiCa battery fully charged how long could I charge or how many times could I charge my phone using a "modified" car charger?(Phone has a 1500mah Li Ion battery) Also im open to suggestions about using a different battery Im trying to go for best bang for the buck but im also considering using a cheap 20$ Li Ion drill battery that is 12V opinions constructive criticism or other ideas are all welcome.
If you had a power circuit made up of multiple batteries in parallel charging electronics like cell phones and one or more of the batteries from the main power circuit are removed after some time, recharged and put back into the circuit, could this be harmful to the electronics being charged?
Can anyone better explain to me wattage, I just need some examples of how much power 1,5,15watts is. I want to use solar panels to charge batteries but im not sure how much wattage I need. In my head the more the merrier but I know that cant be the best idea.
My goal is to make portable solar power source to take with me into the woods and not only charge my cell phone and my friends cell phones at the same time but also act as a fan for me. Ideally I would leave the solar panel outside during the day charging the batteries when im not in the tent, and charge our phones as well as keep myself cool during the night.
Does anyone think that it would be a good idea to try and save battery life with the fans and use a capacitor that would kind of pulse them instead of run them on nonstop?
And finally, does anyone think that this setup with the up to 15 watt solar panel has the power to run an inverter and maybe charge a laptop or just use something that needs to be plugged in?
Thanks for sticking around and reading all of this any and all suggestions are greatly appreciated, Thanks again.
