This best seller is a fake one. I wrote a review and called them to invest 6 month ago. It is still there. Amazon doesn't care. https://www.amazon.com/Solar-Charger-Power-Bank-36800mAh-Bui...

Buy it, measure capacity, and return it. If they don't make you ship it back you get a free power bank.

Just hope it's safe, and doesn't overheat and catch on fire.

meh it's always handy to have an extra LiPo around even if you don't need the electronics
