the advantage is the durable design and the flashlight
disappointment with the quality of the cells, after 2 years noticeable loss of capacity, after 2.5 years it has inflated and is K. O. Only about 50 cycles used.
noticeable self-discharge, almost empty within three weeks
faster charging with better USB(takes more stored energy)
wireless charging did not work even after thoroughly reading the instructions(possibly a defective piece)
after prolonged use I find that the capacity decreases (less recharging)
solar panel after 6 hours in strong sun did not make even one diode of capacity (weak solar panel)-on the way to the end unused (7-day hike to the mountains, so there was no way to charge)
