RE: Teardown/Explanation of a Solar-Powered USB Battery Pack

[proteus-h]

I don't have a ton of experience with boost converters, but I don't believe that the boost converters of any voltage should place significant stress on the battery unless drawing lots of current. Of course to get to 12V you'd need a different circuit than the one presented here.

For example I have a bunch of devices that step up batteries less than 3 volts up to thousands of volts with little drain on the batteries.

Thanks but could u help me with the circuit diagrams of this kind of circuits

Unfortunately I don't really yet have the experience to design any non-crude way to make a boost converter. However, if you look online there are tons of 4 volts to 12 volts boost converters that can take a Lipo voltage up to 12 V (you'll still need the lipo protection circuitry). Here's one:
