I specifically did not want the auxiliary batteries directly connected to my starting batteries, for obvious reasons, and this charger did exactly what I needed. It’s not the highest-output charger available, but for my application the 18 amps is enough, and it charges my auxiliary batteries just fine. The built-in engine shutdown detection is especially useful because it can detect when the engine is running by monitoring the voltage coming from the starting battery and alternator. When the engine is running and the alternator raises the voltage, the charger can charge the auxiliary batteries, and when the engine shuts down, it stops charging so it doesn’t drain the starting batteries. Victron is a brand I’ve had very good experience with, and the Bluetooth connection to the VictronConnect app makes it easy to configure the charger and monitor what’s going on in real time. For my purposes, this was exactly the right solution: reliable, isolated charging for my auxiliary battery bank without risking my truck’s starting batteries. Five stars. Review: Works well! - Installed on my 2018 Ford Transit to charge leisure battery. Works well and fairly easy yo wire. The Bluetooth app lets you monitor charging. Pretty cool stuff for the DYI camper van person. ## Features - PROFESSIONAL DC TO DC CHARGER: The Orion-Tr Smart DC-DC Charger is a professional charger that uses three stages to efficiently and safely charge your batteries. - DUAL BATTERY CHARGING: The Victron DC to DC charger is ideal for vehicles or boats where the alternator and start battery are used to charge the service battery. - BUILT-IN BLUETOOTH: The DC to DC charger can be monitored and cotrolled with smartphone or tablet via Bluetooth and the VictronConnect App. This allows you to see the charger's status and make adjustments as needed. - FLEXIBLE POWER SOLUTION: The DC DC charger is suitable for both lead acid and lithium batteries and unlimited multiple units can be connected in parallel to increase output power. - EASY TO INSTALL: The screw terminals provide a convenient and easy installation process, eliminating the need for specialized tools. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0851TPKV7 | | Amperage | 18 A | | Battery Charge Time | 1 hours | | Best Sellers Rank | #37,976 in Automotive ( See Top 100 in Automotive ) #189 in Battery Chargers | | Brand | Victron Energy | | Built-In Media | Victron Energy Orion-Tr Smart 12/12-Volt 18 amp 220-Watt DC-DC Charger Isolated (Bluetooth) | | Color | Blue | | Connector Type Used on Cable | Screw Terminals | | Current Rating | 18 A | | Customer Reviews | 4.7 out of 5 stars 906 Reviews | | Input Voltage | 12 volts_of_direct_current | | Item Dimensions D x W x H | 2.8"D x 7.3"W x 5.1"H | | Item Highlight | Bluetooth Battery Charger for Dual Battery Systems | | Item Type Name | Victron Energy Orion-Tr Smart 12/12-Volt 18 amp 220-Watt DC-DC Charger Isolated (Bluetooth) | | Item Weight | 1.2 kg | | Manufacturer | Victron Energy | | Mfr Part Number | ORI121222120 | | Model Number | ORI121222120 | | Number of Items | 1 | | Output Voltage | 12 volts_of_direct_current | | Product Dimensions | 2.8"D x 7.3"W x 5.1"H | | Warranty Description | Warranty | ## Product Details - **Brand:** Victron Energy - **Color:** Blue - **Item Weight:** 1.2 kg - **Output Voltage:** 12 volts_of_direct_current - **Product Dimensions:** 2.8"D x 7.3"W x 5.1"H ## Images ![Victron Energy Orion-Tr Smart DC-DC Charger 12/12V 18A 220W Isolated - Image 1](https://m.media-amazon.com/images/I/71Cf-mwN0uL.jpg) ![Victron Energy Orion-Tr Smart DC-DC Charger 12/12V 18A 220W Isolated - Image 2](https://m.media-amazon.com/images/I/71MWDeSwY8L.jpg) ![Victron Energy Orion-Tr Smart DC-DC Charger 12/12V 18A 220W Isolated - Image 3](https://m.media-amazon.com/images/I/61Zxc4IvjrL.jpg) ![Victron Energy Orion-Tr Smart DC-DC Charger 12/12V 18A 220W Isolated - Image 4](https://m.media-amazon.com/images/I/61dNVPii8gL.jpg) ![Victron Energy Orion-Tr Smart DC-DC Charger 12/12V 18A 220W Isolated - Image 5](https://m.media-amazon.com/images/I/512s1rwpLpL.jpg) ## Questions & Answers **Q: This unit has been triggering my RV's low voltage proection, likely from random spikes. Anyone have an idea on how to disable it?** A: Yes, the same thing happened to me with my 30A Victron dc-dc on my 2021 Ford Transit starter battery. The answer is to use the 18A victory dc-dc charger. I learned this the hard way. Some cars can't handle that draw. **Q: Would it harm this victron 12-12-18 if I mounted it in a pickup truck engine compartment, connectors at the bottom and air space around it?** A: For good cooling effect, the Oion is designed for vertical mounting only. Other mounting methods may impair cooling and reduce the service life of the product. **Q: Can I connect the input and output ground together?** A: Yes if not trying to isolate like in a boat for galvanic corrosion. If you don't need the isolation feature just purchase the non-isolated model and save a few dollars. If you already own the isolated model and installing in a RV you can ground both to same ground connection. **Q: I'm looking to find a dc-dc charging solution that also accepts solar input. i'd rather have victron vs redarc or ctek?** A: I use two separate devices. Solar is in series so the input ranges up to 100 volts. It’s nice seeing both via Bluetooth. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Solution for Charging Auxiliary Batteries Without Draining the Starting Batteries *by W***D on July 11, 2026* I bought this Victron Orion-Tr Smart DC-to-DC charger to charge auxiliary batteries I was installing on my truck.

Since it cannot be limited I went with the 12/12 18A instead of the 12/12 30A to ensure I don't blow 12V aux fuses when the batteries are low. We upgraded the batteries in our Jayco 312BHOK to LiPo4 batteries and I wanted to make sure the trailer was "adapted" instead of worrying about back feeding or charging issues. I simply disconnected the Aux Charging leg of my 7 way from the trailer, ran it to the input side of the 12/12 18A, connected the - input leg to the ground coming off the 7 Way, and then ran the +/- outputs directly to my battery bus bars with a 30 amp breaker on the positive leg. It pretty much worked out of the box with one minor adjustment needed for my 2500 CTD Tow Vehicle - I had to change the Alternator detection from "Smart Alternator" to "Standard Alternator", but that was it. It detected that it was charging lithium batteries on its own and it does isolate the camper from the tow vehicle. Doing it this way I am limited to 18A of charge current from the my truck, but that's more than enough to run my 12V fridge going down the highway. We don't really do any boondocking or dry camping so I liked this solution of being able to tow it with any truck rather than using a bigger charge controller with extra dedicated high amperage 12V plugs that would limit me to only being able to charge with my truck towing it. ## Frequently Bought Together - Victron Energy Orion-Tr Smart DC to DC Charger (Bluetooth) - 12/12-Volt 18 amp 220-Watt - Battery Charger for Dual Battery Systems - Isolated - Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - Charge Controllers for Solar Panels - 100V, 30 amp, 12/24-Volt - Victron Energy SmartShunt Battery Monitor (Bluetooth) - Victron Smart Shunt - 6.5V-70V, 500 amp --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/231905882-victron-energy-orion-tr-smart-dc-dc-charger-12-12v](https://www.desertcart.sn/products/231905882-victron-energy-orion-tr-smart-dc-dc-charger-12-12v) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-19*
