The HyperJuice is among the latest in a line of products made to respond to the demand for ultra-compact power bricks for work and travel that can still fully support devices such as the MacBook Pro 16. This one has been made available via crowdfunding by the Sanho Corporation brand HYPER, and is rated for 100W via either of its 2 USB type C ports.
The charger also has the same number of USB type A ports, although they feature a much less impressive maximal rate of 18W. On a more positive note, this little charger packs GaN as a charging material. This enables it to be about the same size as a pack of cards (according to HYPER at least). This technology apparently gives the HyperJuice a power efficiency of 95%, whereas its closest counterparts deliver 91% at best.
It is also touted to be smaller than 100W competitors such as the Wacom charger, the Zendure Super Port 4 and the Anker Atom PD 4, as well as the 87W or 65W power bricks made by Apple. The HyperJuice starts at US$69 via its crowdfunding platform, on which it has amassed nearly $2.7 million in backing thus far (correct at time of writing).
