Review on 🌞 DOKIO 160W 18V Portable Solar Panel Kit - Compact Folding Charger for Camping RV Boat - 2 USB Outputs & Controller for 12V Batteries/Power Station by Tim Burns

To me, this product (DOKIO "150" despite the part number "160") has the widest range of uses I can think of: maximum power for direct input to the Bluettie AC50S and a working PWM controller turned on, which I immediately checked by hooking it up to the battery of a car that had been sitting for a week. The initial charge was 14V at 7A, which gradually decreased as the battery was charged. I leaned the panels against the car for pretty good sun alignment. I then connected the 12V cooler to the car outlet and the USB phone to the charge controller, which handled the extra load with ease. Swiping across the screen showed all inputs and downloads quite accurately. The open circuit voltage of the panels was 22.5V. Although there were no small rings to hang the panels in the case I am VERY happy with this kit. However, I will still get an MPPT controller like BELEEB, but I don't feel I need it now. UPDATE: The included 10A PWM controller just doesn't match these large panels - easily overheats and overcharges the batteries - unless you cover some of the panels to lower the input voltage. I bought a 20A Rich Solar MPPT that can easily handle the full power output of the panels in golf cart batteries. UPDATE REDUX: Using a 10 AWG SAE to DC8 cable to connect these panels to my new Bluetti AC50S, it peaked at 115 watts right after the sun was at its zenith and I was struggling to move the panels . The maximum input power for the AC50S is 120W, so I feel justified in giving it a higher rating. I can try to break the parallel connection between the panels by increasing the voltage and the possible maximum MPPT point.
