Dimension Engineering PicoSwitch RC RelayLVBoost is a boost converter that can take voltages as low as 0.5V and convert them into higher, more useful voltages like 3.3V or 5V. It has an exceptionally low quiescent draw - typically under .4mA. these features make LVBoost a great choice for powering projects from solar or other renewable energy sources.
From a 3V input, 500mA at 5V out is easily achievable, allowing you to charge nearly any portable device that meets the USB spec.
The output voltage is set with a small screw potentiometer on the side of the LVBoost.
Notes from Dave, this is a neat device. Technically, you could use this with a single lipo cell and drive an RX at 5V. Might be a cool solution for a DLG. It has an input limit of 1.5 amps. In order to buck-up or up-convert the voltage, current will be multiplied by the same factor as the voltage (rougly speaking). So, if you want 5v out but start with a 1.2v Nicad as the source, then 1.5 amp / (5v out / 1.2v in) = max output of 360mah would be possible. Using the same formula, from a single Lipo (operates from 3v to 4.2v when full) if we figure the input voltage at 3.7 it would be 1.5 amp / (5v out / 3.7v input) = 1.11 amps out. So, it stands to reason you could fly a DLG off a 130 or 160mah single lipo used in bind and fly models.
