Review: Handy - Charges well for such a small panel. Does not need clear sky to work, which is useful in the uk. I use solar panels for ‘off grid’ van camping to avoid running down the vehicle battery I do have a much larger and heavier 120w ‘portable’ panel but the little Sunjack is just the job for quickly hanging up in the door between the showers which are a traditional part of our English summer.
Review: quite dissapointed, with the total out of 10.4w of of 25w advertised - i saw youtube reviews claiming 16w out of 25w from thie pannels, and i taught thats good enough, but the most i get is 10.4w so dissapointed, i should have bought the 15w smaller pannel instead since 10.4w is soo little for the size in my opinion

### ⭐⭐⭐⭐⭐ My infinite power source 🙌🏻 .
*by M***M on 28 April 2026*

I only tried it once to charge a 20k mAh power bank and it didn't take much time at all to fill it up from 70% to 100%. I don't remember exactly how much time it took, but i think its was around 40 minutes. The experiment was done in an almost clear sunny day. The main reason for getting this product is emergency situation, and it combines the perfect power, and the perfect weight and quality to be used in those kind of situations. I'm very satisfied with this purchase.
