-Other voltages like 9v and 6v are less common.  If you have multiple devices that use the same odd voltage you might want to buy a DC-DC buck converter and adjust it for the desired voltage.
+Other voltages like 9v and 6v are less common.  If you have multiple devices that use the same odd voltage you might want to buy a DC-DC "buck" converter and adjust it for the desired voltage.
 Inexpensive ones ([[https://amzn.to/2QFmHOx|example]]) typically have a "pot" (screw to turn on a potentiometer) to adjust voltage, so bring your multimeter.  They are so inexpensive you might keep a few pre-tuned and labeled for specific voltages.

 If you have an adapter with a weird output voltage and don't want to mess with buck converters a very small, inexpensive inverter might be the thing.  Even one small enough to run from the cigarette lighter ([[https://amzn.to/3gWOKni|example]]).
+==== boost converters ====
+It's rarer still for devices to use adapters that make more than 12vdc.  Increasing voltage from 12vdc to a higher DC voltage requires a "boost" converter ([[https://amzn.to/33bM39j|example]]).  The laptop adapters mentioned earlier are boost converters.
