Rechargeable egg lights : curiosity teardown

It's yard sale season again! i found these odd looking egg shaped lights for cheap and decided to see what they are all about. I couldn't find any reference to these online, so it's a complete mystery going in. If you know where these are sold, or anything else about them, leave some info in the comments. ----- My tip jar:   / pileofstuff   My other tip jar (channel membership) :    / @pileofstuff   Buy me a coffee (or a beer): https://ko-fi.com/pileofstuff If you are OK with me getting a commission on your purchases, feel free to use my affiliate links: Ebay: https://ebay.to/33IF7PA Banggood: http://pileofstuff.ca/r/9ajsf Some other links to products may be affiliate links #ElectronicsCreators ----- This isn't the only way to do it.
