## Customer Reviews

### ⭐⭐⭐⭐⭐ Brilliant product
*by  ***S on 1 February 2025*

I purchased this by chance, the week before a major storm and 3 day power outage. It was really useful for keeping the phones charged and easily positioned to where the sun was shining brightest. Super happy with this impulse purchase at a very reasonable cost.

### ⭐⭐⭐⭐ Charges my jackery slowly, but surely
*by C***E on 10 July 2025*

Its good, it charges, I bought it to charge the jackery & it works, obviously slower than home voltage but yes, it works

### ⭐ Waste of money
*by M***R on 16 March 2025*

Rubbish!!! The charging times are no way near as stated and you definitely can not charge 2 things at once. My Ring camera battery has been on charge for over 24 hours now and is still not fully charged, just plugged my EarPods in and it basically crashed. Don’t waste your money… shame!
