Dave: I love these debunking videos of yours! Thanks!

I've already had quite a few crowd funding campaigns do that actually.
Batteroo are most welcome to send a pre-release one into the Mailbag segment.
I suspect the campaign, even on Indiegogo will be a winner. It's price point is just too compelling for people not to try it.
And it's likely true that you would get your money back in power saved if you used it on just dead batteries.
That doesn't stop the downsides of course, but many will look at it from just that perspective.

Nope, my video will amount to a hill of beans. Target audience for this product is Joe Average, and not electronics design people on my channel. Electronics people can instantly see the many downsides to it, so likely never would have bought it.
You wait, the campaign will go bangbusters.
Actually, I want it to get funded so I can actually get one to check out the miniaturisation and how they are doing that.

IMO they would have been far better off putting it in a clip on attachment for 9V batteries somehow . That is more of a problem than AA/AAA powered devices, and the batteries are more expensive. Plus potentially more room for bigger and better magnetics, less maximum current requirement, and no shorting problem.
SL4P:
When I first saw this thread, it reminded me of a gadget I intended to develop - primarily for kids toys... but almost anything that 'gets left on'...  exactly the same form factor.

A one-shot that turns a FET on with the power switch, and while 'in range' current consumption. (C)2005. MDC/SL4P

If the unit is idle, or over-current for more than a hard-coded period (e.g. idle 2 mins, over-current 5 secs), it shuts off until the power supply is recycled.
Save batteries and kids from grinding their toys to death!

Unfortunately, my situation has me dead in their water for the last few years - so these ideas are just a dream now.  I'll share if someone else's wants to do it!    Call me!

Yes, remains to be seen what the production version can and can't fit into. If it's 0.1mm as claimed then that should be good enough for a majority of products?
