Hey everyone, I'm curious if I can use a solar panel to charge my UGREEN Nexode Power Bank, which has a capacity of 20000mAh and supports up to 100W. Do I need any special accessories to ensure smooth power delivery while charging? Any tips would be greatly appreciated!

It's important to get the voltage right! Your power bank needs to be charged down to 5V. Since 20 amp hours isn't that huge, any panel that meets this requirement should suffice. Just remember that a USB PD (Power Delivery) controller is key for negotiating the correct voltage, so choose wisely!
To charge your power bank effectively, look for a solar panel that has a USB controller built-in. Brands like Flexsolar and Marbero offer panels that can communicate with your power bank for the best results. Since your power bank is about 74Wh at 3.7V, you should aim for a panel that can deliver at least 15W consistently. This means a 30W-rated panel should do the trick!
Yeah, exactly! USB battery banks usually operate with multiple voltages, so that controller helps prevent delivery issues. It’s definitely worth double-checking that compatibility before you buy.
