Looks neat but I’m actively avoiding micro-usb port devices, in favor of usb-c.
More than likely this is just outdated tech being flushed out their warehouse to introduce new versions of it with USB-C. I totally agree with you too.
Welcome to woot!
But “anti-skid”??? How can you pass THAT up?
The mother ship has the gold one with usb-c for $15.99: Karecel Rechargeable Hand Warmers, Electric Hand Warmer 5200mAh Powerbank Reusable Handwarmers, Portable USB Hand Warmer Heater Battery Pocket Warmer, Best Gifts for Men and Women in Cold Winter https://a.co/d/dcyBi6J
Is this a USB C version for the same price? $12.99

Lithium-ion batteries sandwiched between 2 heaters is an awesome idea! 
Yeah, that thought occurred to me too. What could go wrong?
Why yes, sure looks like it.
It’s a bonus surprise super heating mode!
Abs so freaking lutely!
One of the USB-C For the same 12.99
