I have a Jeep with 160 amp alternator and dual batteries under the hood. I camp with an Ecoflow River 2 Pro (Max input is 50v, 220watts using the solar input). I have the solar input wired direct to the "house" battery and it still only pulls the same low 8 amps as the cigarette lighter. Must be the 14v input limiting my charging.
I can get a Victron Tr-Smart DC-DC for $160 that at max will put out 30v and 240 watts- right up there at the limit and that should get me some pretty quick charging while driving several hours a day. The Victron can be mounted in the engine bay and run DC cables to the Ecoflow in the back. It's also only $160.
The other option is to wire in an inverter and charge via AC. The Ecoflow can quick charge on AC in an hour and pull up to 940 watts doing so. I'm assuming that would mean I need a 1500 or 2000 watt inverter and the associated heavy DC cables plus a place to mount it. Another negative is their size and cost- $200-500 depending on brand.
