Purchased for motorcycle camping unfortunately we have to take a cpap machine with us. We dont pack light lucky motorcycles 1800cc Worked great powered cpap for 10 hours no problem. Had a few problems with the power station shutting off when we had the 40 l Engel plugged in but just connected a tiny pen light in one of the usb so when the compressor shut off on the fridge it didnt turn off the power station. Also we purchased cheap solar panels from another supplier and had to connect a tiny 1.5 amp battery to charge their regulator so that the solar panel would put power into the power station. All working fine now. Power station charges fully within 6 hrs with 200w panels. Im so impressed with this little box perfect for all that we need and some. .
