Compact waterproof alloy step-up converter with short cable

GCON

GCON DC 12V to 24V Step-Up Converter 10A 240W Adapter

SKU CH-H3EW-5DT1H

Converts 9–20 V DC input to 24 V output at up to 10 A with waterproof housing and multiple protections

  • Steps 12 V up to 24 V for vehicle systems
  • Accepts 9 to 20 V input for flexible sources
  • Delivers 10 A continuous at 240 W output
  • Waterproof alloy housing suits harsh environments
  • Built-in protections guard against faults and heat

Vehicle Power Conversion

This GCON step-up converter transforms a 12V DC vehicle supply into a stable 24V DC output rated at 10A and 240W. It suits installers who need 24V power for accessories on trucks, boats or solar setups without adding a second battery bank.

9-20V Input Range

The unit accepts any DC input between 9V and 20V, so it tolerates voltage sag during engine cranking or fluctuation from alternator regulation. Supplying less than 9V or more than 20V will trip protection or damage the converter, making this range the single figure that decides compatibility.

Compact Wiring and Protection

Flying leads roughly 12cm long keep the wiring tidy inside tight compartments, and the waterproof alloy housing resists moisture and vibration. Built-in over-voltage, under-voltage, overload, over-heat and short-circuit protection shuts the module down before components fail, so most installation issues reduce to confirming correct polarity and adequate input current.

Questions about this item

What does the 240W rating mean for devices I connect?

The converter can supply up to 240W of continuous power at 24V, so any load drawing 10A or less will run without tripping the overload protection.

What input voltage range does the 9-20V spec actually accept?

It accepts any DC source between 9V and 20V, so a 12V vehicle battery, a 24V system dropped to 12V, or a solar panel within that window will all work.

How much space do I need for the 12cm cable and housing?

The unit has a 12cm lead and a slim waterproof alloy case, so it fits in tight vehicle cavities, control boxes or marine panels without extra brackets.
