A campsite at dusk with a dead phone shows the problem this guide answers: how to step up DC voltage when a battery bank gives fewer volts than the device needs. A small boost converter module sits between the bank and the device and raises the voltage to the level the device wants. The steps below show how to pick the module, set its output and check it with a meter before the load goes on.

How to step up DC voltage in short
Read the voltage the source gives and the voltage the load needs, then pick a boost module whose input range covers the source and whose output range covers the load. Set the output with the module adjustment screw while a meter watches the output, and only then connect the load. The DORHEA module (on Amazon) in the gear section covers 2-24V in and 5-28V out, while the XIITIA module (on Amazon) covers 8.5-50V in and 10-60V out, so the range you need decides the module.
Match the module to the voltage you need
Start with the voltages that matter: the voltage the source gives and the voltage the load needs. A module only works when the source voltage sits inside its input range and the load voltage sits inside its output range. The DORHEA and AITRIP modules take 2-24V in and give 5-28V out, which covers a 5V, 9V, 12V, 18V or 24V load from a low-voltage source. The XIITIA module takes 8.5-50V in and gives 10-60V out, which suits a higher-voltage load such as a 24V device fed from a 12V bank. The EKYLIN converter (on Amazon) is fixed at 12V in and 24V out, so it suits only that pair.
Current matters as much as voltage. The DORHEA and AITRIP modules list a 2A maximum output current, while the XIITIA module lists a 15A maximum input current and a 12A maximum output current. The EKYLIN converter lists 5A and 120W. Pick a module whose maximum current covers the load with room to spare, and remember that a boost module draws more current from the source than it gives to the load.
Set the output before you connect the load
Adjustable modules have a small blue adjustment screw that sets the output voltage. The DORHEA listing describes the first-use routine: with the module unpowered and no load connected, turn the screw counterclockwise to the end, then clockwise more than 30 turns, then connect power and use a meter to watch the output while you turn the screw to the voltage you need. Set the output with no load connected, since the load should only see the voltage it needs.
The AITRIP module (on Amazon) takes its input through a Type-C USB connection, which suits a USB power adapter as the source. The XIITIA module uses screw terminals for input and output, so the wires fasten under screws and come off again without soldering. The EKYLIN converter has no adjustment screw in its title, so its output stays at the 24V its title states.
Check the output with a meter
Connect power to the module with no load attached and put a meter across the output terminals. Turn the adjustment screw until the meter reads the voltage the load needs, then leave the screw alone. The DORHEA listing says to use a meter to monitor the output voltage to reach the voltage you want, and the same routine works for the AITRIP module. A meter reading beats a guess, since a screw turned too far can send the load more volts than it wants.
Connect the load and mind the heat
Once the meter reads the voltage you need, connect the load to the output terminals. The XIITIA module carries 2 heat sinks to move heat away from the board, and its listing says to decrease power and current when the gap between input and output voltage is big. The DORHEA and AITRIP modules state under-voltage lockout, current limiting and thermal overload protection, which guard the module when the output is overloaded. Give the module air around it and keep it away from flammable material while it runs.
How to step up DC voltage: the gear
The modules below cover the ranges and currents in the steps above: the DORHEA and AITRIP modules handle low-voltage sources, the XIITIA module handles higher power, and the EKYLIN converter covers a fixed 12V to 24V step.

FAQ: power away from the grid
Can a boost converter raise 5V to 12V?
Yes, when the module range covers both voltages. The DORHEA and AITRIP modules take 2-24V in and give 5-28V out, so 5V in and 12V out sit inside those ranges. Set the output with the adjustment screw and check it with a meter before you connect the load.
What does the adjustment screw do?
Turning the screw changes the output voltage. The DORHEA listing describes turning the blue screw counterclockwise to the end, then clockwise more than 30 turns, then connecting power and watching a meter while you turn the screw to the voltage you need.
How much current can a small boost module give?
The DORHEA and AITRIP modules list a 2A maximum output current, while the EKYLIN converter lists 5A and the XIITIA module lists a 12A maximum output current with a 15A maximum input current. Pick the module whose maximum current covers the load.
Can a boost converter work as a solar panel voltage regulator?
The XIITIA listing says it can serve as a voltage regulator for solar panels. Check that the panel voltage sits inside the 8.5-50V input range and the load voltage sits inside the 10-60V output range.
