Convenient for DIY -- You can use this module to DIY an output-adjustable car power supplyInput voltage: DC 10V-32V, Output voltage: DC12V-35V(adjustable)Input current: 16A (MAX), Output current: 10A (MAX)Conversion efficiency: 94% (For reference: when Input 19V 2.5A Output 16V)Easily charging for 60W, 90W etc. laptops which is less than 150W, industrial grade ( -40 degree to + 80 degree) work temperature, suitable for AC adapter, power supply and so on
Yes, step down, but..... it can take varying input as low as 7v and can still maintain 12v output, it just cant push the amps at that low of voltage.
here's the step up version, the input/output voltages are pretty close to the step down

modifying them to accept external voltage is both cheap and effective.
I have 4 dc boost modules, one per axis + single extruder. with the printer running and the heated bed off (since it cycles on and off when it only needs to be at 60degC), the control board + the boost modules + the fans + the heater cartridge + the LCD screens (I have a TFT28 and RepRap discount controller hooked up at the same time), the printer consumes about 84 watts when printing (measured at the AC input).
You could do what I did a lot easier by using just one unit like this 150W one: https://www.amazon.com/Gowoops-10-32V-Converter-Adjustable-Voltage/dp/B00J1X4XXM/ref=pd_sbs_328_1?_encoding=UTF8&refRID=GBF90A2DQJT7VEMF415F&th=1
or perhaps even this one since it's about 100W

I think the total power consumption at 30V is around 60-65 watts (at the AC Input), so with air cooling that should work fine.
A step-up voltage regulator would do it. You'd need a rather high amperage though.

The lipo chargers others have recommended will work fine but you can't plug the batteries right into the arduino. You will need a step-up convertor between the battery and the Vin pin.(The pin requires 7V-20V, the battery only supplies less that 4.3V).
Use this to supply power with Vin pin : https://www.amazon.com/dp/B00J1X4XXM/ref=cm_sw_r_cp_awdb_4HHpzb38W89HY
