Volt conversion with mobile charger ? Answered

Hi,

I have to DC device  a) works with 5.V    (b) 1.5 Volt...  I am using mobile charger as a power supply.  How can i connect them with one mobile charger....as the charger output is 5.V  only.  a) works fine but as the other device require 1.5 Volts . Which type of power  component should i use to supply additional appox. 1.5 Volts ? will any of these can device blast ? Any type of tips n tricks will be very help full.

Battery booster packs are available with 1, 2, or three batteries.
Take a model with a single battery and you have 5V output and 1.5 directly from the battery.

While this works the run time of the battery is limited. But he isn't asking for a battery power solution to allow his mobile charger (likely a rechargeable battery pack) to supply both devices.

Hi, right..not looking for battery pack, though thanks al for the tips... i also tried using 4.3 V ~70mA charger in my in ( a) device it works fine...if i connect it in SERIES ..one after another (a) and then b)

b) requiring 1.5 volts, can i power that device with same charger ..i don't want more but appox...1.5 volts... ? is it possible to work without any resistors? also sorry my mufti meter is not accurate...to test it..

1 charger 2 dc device...appox. 5 volts & 1.5 volts ( normal pencil cell volts ) respectively . Should i try connecting it ? i don;t want to harm my devices ?

Please guide...n suggest...

Thanks Again !

You will want to connect the devices to the plug in parallel. But you will need a voltage regulator like i pointed out in my other comment between the 1.5V device and the plug. Sorry but the regulator and resistor are needed in order to get the 1.5V the device needs.
