Anyone can advice 3.3v dc booster for battery powered project on ebay ?
I found this http://m.ebay.com/itm/231083181020 and this http://m.ebay.com/itm/231062865700 and i send message to the seller for idle power consumption and i am waiting response. If anyone has any suggestions I would be glad.

Soldering on the second one looks a little suspect...
DC to DC circuits are not very efficient...

What is the input voltage and what voltages do you require?
