Update September 29, 2022: This product has been recalled due to a potential fire hazard.
Following a successful Kickstarter campaign, accessory maker Hyper today announced that its stackable 65W and 100W chargers based on space saving and power efficient gallium nitride (GaN) technology are now available.
The new HyperJuice chargers each feature a pass-through AC power outlet that is rated up to 1500W, which can be used to power devices with a pronged power cord like the full-size HomePod, or to stack additional HyperJuice chargers to create a "supercharger" with up to 64 ports and up to 1600W of power from a single wall outlet.
Priced at $69.99 on Hyper's online store, the smaller 65W charger features two USB-C ports rated at 65W and one USB-A port rated at 18W. The larger 100W version retails for $99.99 and is equipped with three USB-C ports rated at 100W and one USB-A port rated at 18W. (The 100W version is currently out of stock.)
Hyper says GaN semiconductor material based on Navitas GaNFast technology allows these chargers to be 10x smaller, 100x faster, and 5x more power efficient than traditional silicon chargers. A report earlier this year claimed that Apple is planning its own GaN chargers, but it is unclear when they would be released.

I have one, from kickstarter. First, it came out many, many months late with little to no good communication (just go to the kickstarter page yourself to read through the comments). There are also reports from many of the backers o issues or dead units. Personally I would wait until generation two of this unit comes out. I am not saying there is a gen 2, just that with the number of returns from the kickstarter, there are definitely some issues.
While mine does seem to work, I cannot travel with it and leave my apple unit at home yet, just don't trust it. Will take a few months of use to get to the point I stop worrying.
The passthrough is great, but not a grounded connection. Not a big deal, but something to keep in mind.
If anyone was for some reason thinking of actually doing this (no, you aren't), keep in mind this might violate electrical codes in the US.
For a 15 Amp circuit (not a 20A kitchen plug etc), the NEC limits a continuous load to 1440W. 15A * 120V * 80% = 1,440W This isn't likely to be a practical issue, so whatever.
I have it from Kickstarter as well. Not bad as I carry it in my travel bag. Just remember the power is shared, you're not going to get 65W / 100W per port if you have multiple devices connected to a single charger

Apple today released several open source large language models (LLMs) that are designed to run on-device rather than through cloud servers. Called OpenELM (Open-source Efficient Language Models), the LLMs are available on the Hugging Face Hub, a community for sharing AI code. As outlined in a white paper [PDF], there are eight total OpenELM models, four of which were pre-trained using the...
Apple has dropped the number of Vision Pro units that it plans to ship in 2024, going from an expected 700 to 800k units to just 400k to 450k units, according to Apple analyst Ming-Chi Kuo. Orders have been scaled back before the Vision Pro has launched in markets outside of the United States, which Kuo says is a sign that demand in the U.S. has "fallen sharply beyond expectations." As a...

looks like the 100W unit is already sold out
