Review on 🌞 Himino 20W Waterproof Solar Panel Battery Charger with USB Output Ports - Portable Solar Charger for Car, RV, Boat, Cell Phone & More by Eduardo Reyes

On the 1st photo you can see how it charges external batteries. It can also be other small devices. Figure 2 shows the back. Rear accessory socket included. (Haven't used them) Fig. 3 - Dispense quantity. It has 2 USB ports but depending on what you want to charge it will charge one at a time. It says 12V/5V but I think it's only 5V. Unless it's a wired port on the back. On fig. 4 shows the plate thickness. It is thin and easy to store and carry. I sometimes tie weights in the corners on windy days. What else you need to know: It also charges in cloudy weather and in the shade. Comes with suction cups so you can attach it to a window or a parked car window (under the sun). Great if you're hiking. Monthly test: 26000 mAh external battery provides about 24 hours of sunlight. For 24000mah it takes 14-18 hours. 8000 mAh takes about 4 hours. iPhone SE 1-2 hours. All day long you can charge the tablet at 65-85% (do not forget to turn off all applications on your devices). All in all it's great. I only wish I had 20 watts instead.
