They’re all solved problems!

That doesn’t change the fact that every additional complication adds cost, complexity, failure points, more warranty returns, and time to market.

Saying it’s just a transistor and a TVS ignores the hard parts like sealing the enclosure and building an entire second device to charge it.

Solvable, but less so for a low volume product with unproven demand. You have to be building a lot of a product to offset the costs of developing it.

> $75 for a use once device that could last as little as a few months under normal usage, or $100 for something that could operate for 5+ years.

The retail price of this device is $99. The $75 is only for the promotional preorder period.

It’s already a $100 product. Adding charging ports and a separate charger is going to be even more expensive unless they start shipping 100,000s of these to build at scale.
