Orion XS 12/12-70A DC-DC battery charger (ORI121221040)

Turn your engine's alternator into a smart charging source for your service battery. The Orion XS packs serious charging power into a compact, completely fanless housing — no moving parts, no noise, no maintenance headaches. Choose from 12V or 12V/24V mixed-voltage models, making it a great fit for dual-battery systems or as a dedicated DC-to-DC converter protecting sensitive onboard electronics.

Built to work with virtually any alternator and battery combination, the Orion XS lets you fine-tune both voltage and current output to match your setup exactly. It runs at up to 98.5% efficiency and holds its full rated output even in demanding heat, up to 40°C/104°F — no derating when you need it most.

For vehicles with smart Euro 5/6 alternators, the Orion XS pulls a consistent, predictable load that keeps these alternators from cutting back output, so your service battery gets a proper charge instead of being left undercharged. Its 4-stage charging algorithm reads the battery's depth of discharge and adjusts on the fly, helping maximize lifespan across lead-acid, AGM, gel, and lithium chemistries alike.
