Sunjack 15W Portable Solar Panel Charger
Sunjack 15W Portable Solar Panel Charger
This Sunjack 15W solar panel actually charged both our phones—when it was in real sunlight. In my tests, I got up to about 11W in direct sun and it took around 2 hours to fill my phone, but in shade it was basically 0–1W and didn’t truly charge. I rated it 6/10: useful in remote multi-day situations, but often a power bank is simpler.
