Wow; this battery is an astounding waste of gelt. You can get somewhat less pretty but very rugged battery banks with a solar panel for 1/3-1/2 that price, FFS. Excellent example ($39.99, 16,000 mAh, solar panel, “ruggedized”): https://www.amazon.com/OUTXE-16000mAh-Flashlight-Waterproof-Portable/dp/B01MDR2LDK/ref=zg_bs_2407762011_2?_encoding=UTF8&psc=1&refRID=CENAR69RCQXMKYV946EC. There are many other perfectly legit offerings, as well. For example, the KMASHI 10,000 mAh offering — possibly the one mentioned above by jlw —is $13.99!
Seriously, Boing Boing…?!
