I received an Oukitel P800E power station + PV100 panel 10 days ago and charged it immediately to 100%. For 10 days there is 0% self-discharge, which is excellent. Weight is 5.9 kgs and is very convenient to transport. Comes with its own power cable and a MC4 to DC5521 50 cm long cable. Ports work well, the integrated LED flashlight has 2 power levels + 1 strobe. The 12V cigarette lighter port has a rubber protective cap, but the Schuko socket and the USB ports do not have. It would be nice to put protective dust caps on them too. The item is portable and is very useful on campings, so some dust protection of the bare ports would be fine. The extra covers can be bought separately, by the way. It is also a good idea for users to buy an extra 12V car cigarette lighter to DC5521 charger cable with a replaceable fuse. Delivery was fast, packing was excellent and I would definitely recommend the item and the seller.
