I bought the Bluetti AC300+B300 combination on Amazon Prime Day (July 11, 2023) after watching Bob Well's videos Choosing the Right Power Station for Van Life! and Cheap Deals on Power Stations During Amazon Prime Sale Days July 11-12, 2023 among other videos. I got a great deal and everything tests fine so far. The instructions say to avoid vibrations, especially when using the AC300+B300 combination. For example, the AC300 instructions say "DO NOT move the unit while operating as vibrations and sudden impacts may lead to poor connections to the hardware inside." Of course, connections can come loose whether or not the system is in use. How rugged and durable are the AC300 and B300? Could one drive in a car, van, RV, etc. using the AC300+B300 to power a fridge, mobile StarLink, etc. without (much) risk of damage to the Bluetti system? Couls one drive on poorly maintained (forest service) roads with little risk? (Having to return the combination to Bluetti for repair would be a major pain.)
