Summary: I have reviewed several solar radios so I will compare them to others (listed below). Observations: First I will tell you what all three have in common: a) Powering a lithium battery by solar panels; b) can be used as a USB power bank; c) FM radio. Other differences: a) This one (Greatone) is the only one with dual power, AAA power; b) Lukasa only FM and digital with presets, the other two also work with AM/WBS; c) Lucas also has outdoor lighting; d) es and WDGSSA have manual loading; e) Lukasa 5200 mAh, WDGSSA 4000 mAh and this 2000 mAh. Recommendations: There are many options, even between these three; Take a look around to see what features you need to fit your needs and budget. Pros: Good fit and finish; 9 inch antenna. Cons: 2000 mAh battery capacity (the smallest of the three). Verdict: At $28, I'm rating this phone 4 stars over the other two below. My first recommendation is Lusaka, mainly because of the large solar panel and large battery capacity. The second recommendation is WDGSSA, again for high capacity batteries. Third, this is Greatone.
