Hardwire charger for fleet and mobile use

The RAM Mounts GDS modular hardwire charger converts an 8 to 40 volt DC supply into a regulated 5 volt output at up to 2.5 amps. It connects through a Micro-B USB male plug directly to a GDS dock or any compatible USB device. The unit is designed for permanent installation in fleet vehicles, consumer automobiles, ATVs and motorcycles.

Thermals noise and power draw

As a solid-state step-down converter the charger has no moving parts and operates silently. It draws power only from the host vehicle’s DC system and delivers a steady 5 volt rail without generating audible noise. Typical surface temperature remains low enough for enclosed mounting in vehicle cabins or fairings.

Quick Charge and Apple fast-charge support

The module supports Qualcomm Quick Charge 2.0 and 3.0 protocols alongside Apple 2.1 amp and 2.4 amp charging profiles. Devices that require other proprietary fast-charge standards will fall back to standard USB power. Buyers needing Power Delivery or other voltage negotiation should verify compatibility before purchase.

Questions about this item

How do I install the hardwire charger and which wiring step is most often missed?

Connect the unit to an 8 to 40 volt DC source, then plug the Micro-B USB male connector into your GDS dock or USB device. The step most often missed is verifying the supply stays within the 8 to 40 volt range before powering on.

What maintenance or replacement will the charger need over time?

The converter has no user-serviceable parts and no internal battery to replace. If the Micro-B USB cable or connector wears out, the whole unit is swapped rather than repaired.

What is the first limit reached under sustained use?

The 2.5 amp output ceiling is reached first; sustained loads above that will cause the charger to limit current or shut down.
