I travel reasonably often, and would find something like the MagStack (advertised at MacWorld) very handy. However, as far as I can tell, the MagStack and what appear to be identical models under different manufacturers’ names are uncertified by the Wireless Power Consortium (WPS), Apple, etc.
WPS has a database you can search here:
My experience with a couple of Qi-compatible (but not certified) chargers was not very good, resulting in temperatures much higher than what I’m accustomed to with WPS and Apple certified products, and have been enough to put me off saving a few bucks on uncertified products.
I haven’t been able to find something similar to this that is WPS and Apple certified, and if anyone is aware of a folding travel product (ideally with USB-C PD passthrough) I’d really love to hear about it.
Thanks in advance.
