I bought this with the intention of using it as a substitute for a custom battery, charger, inverter, solar controller in my campervan project. In theory, the sum of it's parts was cheaper than all of the other items combined, and with a lower wattage requirement (no electric cooktop, 12v lighting, etc) this seemed like the more cost effective route.Overall, I have 2 sets of 120v outlets connected to this all the time, with a 12v circuit running the lights onboard as well. I also have shore power run directly to the compartment this lives in. I have not tested the solar input yet.(picture gives a rough idea, the male outlet off to the side is what powers the onboard outlets, it's just not plugged in in the picture)(fridge is to the immediate right of the Bluetti, for context)(app screenshot is with nothing powered, but for context of UI)It absolutely performs the job as expected, with a few caveats. I'll begin with the good:Good:-Lightweight considering it's the size of a small car battery and provides more power (I know this is an obv difference between gel-cel and lithium batteries, but worth mentioning)-quiet, although it lives under a wooden bench seat. In the open it makes an "amount" of fan and inverter noise.-seems to supply wattage as expected, fast charging from the AC outlets works great, powered a cooler style fridge/freezer (with a compressor, so used ~110w at peak) for 3 hours when full and only used about 10% of the battery.-App has received a revamp recently and is very user friendly, as well as picks up status when re-opened. I find some of these products with companion apps don't persists once the app is closed / device disconnects from BT.-build quality feels high and the foldable handle was a big plus compared to other brands like Jackery with a fixed handle (space saving is important for my application).-built in physical circuit breaker adds peace of mind-surge power is nice to have in case it was needed for something out of the ordinary, although I have so far avoided having to use it.-charges fast from shore power-did not complain *too much* when placed in a warm ambient temperature environment. I keep this device, and the refrigerator under the same bench, so they're basically blowing hot air at each other. Not to mention the inside of the campervan get's quite hot when the AC isn't running (probably 30C+ air temp during the day). I mostly did this as a test to see if it would shut off at a point. As of yet, the device seems to throw warnings in the app, but stay running. Which is good."bad", really just some qualms-eco mode shuts off outputs (AC/DC) when it doesn't detect more than a few watts, so when I turned my camper lights (12v) off at night, the output was off in the morning. I may simply plug in a night light to the USB port on the device to keep it running, but so far I can't seem to disable eco mode without enabling the "power lifting" (surge wattage) mode, only delay it's grace period.-flashlight is all but useless, it's pointing the wrong way for ergonomics and if they really wanted it to be useful, they'd have made a light ring around the chassis to use the device as a lantern instead of a pointed flashlight. More than anything, I'd prefer another 30 min of battery capacity over a flashlight module.Overall, this does what I wanted it to - gave my campervan AC and DC power for less than 400$ and 1/4 of the space. If the app had the ability to turn off eco mode, this would be 5 stars.
