At 60% and 30% smaller than Apple's 67W and 140W power bricks respectively, INVZI touts its competing accessories as the "world's smallest" chargers with those specs. However, they are rated to supplant their first-party rivals in their entirety by packing GaN power technology and the USB-PD 3.1 standard.
In the case of the slightly larger variant, the INVZI is also rated to support the "smart" ICs that should control this potentially blazing-fast charging speed in accordance to the requirements of the device plugged into it.
Therefore, a MacBook Pro 14 plugged into its 140W port will charge at its more optimal 100W rate, whereas a 16-inch unit can go ahead and power up at the full rate. In addition, the OEM asserts that they are compatible with the new MagSafe to type-C cable.
The INVZI 67W and 140W started out as Indiegogo rewards. This campaign ended on July 16, 2022 with a total of US$191,035 worth of backing; however, they and their distinctive 3D-pinstripe exteriors can still be found on this site, at prices of US$25 and US$59 respectively at the time of writing.
This graduation to InDemand status might improve the chances of INVZI fulfilling its backers' orders. On the other hand, it should be noted that the chargers' worldwide shipping date has now slipped from an originally projected June 2022 date to August - a month that is now almost over.
In addition, be aware that neither INVZI variant has even 1 type-A port (because that's the way things seem to be going at this stage). Therefore, as with all similar projects, exercise caution before committing to pay for one of these potentially super-portable type-C device companions.
