Using a switched mode DC/DC converter to transform voltage down and current up. This helps match the load to the source.

Excelent video horrible Audio Speach varying audio volume levels you talk slow and then talk fast and swolow words
great videos, simple and informative
Dear Julian, Thanks for this simple explanation. Even I understood it. I am trying to power a LED PIR surcurity light from a 20w solar cell/12v car battery.
you seem to misunderstand what the current limit adjustment on your dc-dc convertor does. all you have to do is get the voltage right, and then ensure the current limit is set a little higher than the bulb draws in that condition. The only function of the foldback current limit is to protect the convertor if the load has too low a resistance for the chosen voltage.
Well searched and approached subject, As usual. Thanks Julian. Will search for this Solar converter on Ebay.
Thanks Julian; very helpfull.
Very interesting videos
I too have been messing around with these things lately and I think you should try using a much "lighter" dc-dc converter with much smaller inductors etc and no on-board electronics to rob power, many of these power sources have output current limiters that will not start up "heavy" dc-dc converters due to inrush current tripping their protection circuits. I also suspect that their input resistance/impedance will be generally higher enabling a better power transfer from low power/current energy sources. Something like the small 2V minimum input voltage (2- 24v boost) maximum 2A output dc-dc converter, slightly smaller than the ones you have reviewed might work better for you here.
Thanks for some interesting things
Did you make the converter or was it an eBay buy I would like to have one of those.
nice and easy to understand video. thanks
gj is there gonna be part 4?
You are soooo subscribed
nice videos and good information very well explained, good job !!!
