The voltage varies over the charge/decharge cyclus of the batteries. I think fully charge batteries are 7,2 volt and discharged batteries are 5 volt (5 NiMH cells). Thats why I think the diode solution is not ideal. From what I have read on the web the 7805 solution will not work because of the...
Does anyone know if a smartphone has a voltage regulater build in so the phone don't need exact 5,2 volt?
I ask because I have discoverede that a normal 12v usb charger will charge the phone with 6v when delivered 6v. I guess it needs the 7v or above to regulated the voltage. When below it...
I have a bicycle with a 6 volt system. The system is powered by NiMH (4,5 Ah 6V(when charging the voltage goes up to 7,2-7,4v and I guess it goes down to 5vt)).The system has lights, horn etc. I want charge my smartphone (HTC One S). Which option should I go for?
1. Assume that the smartphone...
The DIN 45323 looks like the right answer. Also the correspondent socket looks like the one that sits in the board. Thanks very much. I will buy and try.
