Re: Need help with solar powered mobile charger...please see!!
Just an update, quite surprisingly, my new cellphone charges just fine and as expected with the same solar panel setup. I don't know why why previous Xperia acted so odd with the same setup.
So far, all the devices are working without the help of power from the molex connector.

Hello Peter, I don't know where the cables come into the picture in my case. I, as an installer, did not come across any such cables. It's just an expansion card which goes into the...
Hello hello.
It's working just fine without the molex connector. All the devices, including the flash drive that was replaced, are working fine without the connector. The connector is a Molex 8981 Power connector (female). I am 100% sure I had connected the connector with the correct...
I just measured the short circuit current output from the USB ports and also the open terminal voltage.
Without molex connector the current is about 2.4A (SHORT CIRCUIT CURRENT!) and voltage around 5.3V.
With molex connector, the voltage showed to be 12.33 V!!! I was worried about short...
I bought a USB 3.0 PCI-e internal expansion card off eBay because my computer didn't have USB 3.0 ports. It also has a molex 4-pin connector.
I installed in on my machine (also plugged the molex 4 pin connector to an unused one branched off the hard disk connector) and plugged my brand new...
I already stated in my reply that for the sake of the discussion here, it's not one of the concerns whether or not the circuit will continue or stop operating. I simply ask whether or not the power usage will vary.
And how is it that power doesn't affect the capacity? If the capacity is a...
I still can't seem to buy that. What does the statement "A 1400mAh cell or battery should be able to supply 1.4A for 1 hour" even mean? For a battery of 7.2Ah, a load which demands 7.2A from the battery if connected to it will run for one hour and then suddenly stopping after an hour? It would...
So, in other words, if I have a DC circuit which consumes a certain amount of power from a battery thereby depleting it and now, for any arbitrary reason, I want the battery to last longer and thus reduce the amount of power drawn from the battery so as to prolong its runtime (disregard the...
Re: Need help with solar powered mobile charger...please see!!
Still waiting for your solutionnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn :S
Suppose there are two circuits as described below:
a) A 12 V Battery to which connected are a 10Ω and 20Ω resistors in series thereby completing the circuit.
b) A 12 V Battery to which connected are a 10Ω and a 100Ω resistors in series thereby completing the circuit.
Both of the above...
Re: Need help with solar powered mobile charger...please see!!
I had bought 2600mAH solar panel powered battery bank off ebay and it arrived today. I just now tried charging my phone with it. Funny thing is that the android app now shows the charging current to be around 100 to 140 mA but the...
Re: Need help with solar powered mobile charger...please see!!
Hmm... and how shall that be done? If I am using Darlington pair such that solar panel serve serve as the source of energy that will be used to create the load current, then what will drive the base of the darling ton pair?
Re: Need help with solar powered mobile charger...please see!!
Yes, I am using it. But how do I use the solar panel to BOTH drive the load (that is the phone) and also provide the base current? What purpose will that serve?
