Bluetti ac180 power station. Have only used it 2 times. The display shows weird when ac is turned on. U can use tour phone app which is what i did any way to see everything going on. The unit is fully functional. Took the whole family camping and it kept everything charged and music playing. Only reason i am selling is bc i want something bigger as i wanna upgrade my over all off grid set up. Make an offer. Have the dc and ac charging plugs as well
