Built one into a portable field charger and the wide 3.5-35V input range meant I could use whatever battery I had lying around. Easily pushed 5 amps continuous without the module even getting warm.

Took a 12V battery down to around 4V and this thing still pushed out a steady 24V for my LED strip setup — that 3.5V minimum input range really saves the day. The board runs surprisingly cool even at 2A draw, so no heatsink needed in my enclosure.

Works perfectly for my 24V solar charge controller project; the input range from 3.5V handles my panels even on cloudy days. Fits nicely in a small enclosure too.
