Fermi · Power adapters · GaN3
Four sizes of fast.
Fermi is gallium-nitride charging in four outputs: 30, 35, 45 and 65 watts. One or two USB-C ports, USB Power Delivery with PPS, and the right size for every iPhone generation, iPad and MacBook.

Choose by what you charge.
One family, four outputs. Pick by the device you charge most; every Fermi shares the same GaN3 power stage, protection and standby figures.




Why gallium nitride.
Gallium nitride switches power many times faster than silicon and wastes less of it as heat. That lets the parts around it shrink, so a Fermi adapter carries more watts in less space and runs cooler doing it.
Fermi uses a third-generation GaN topology throughout the range.

Fermi45 and iPhone 17: half full in 20 minutes.
iPhone 17 takes its fastest charge over AVS, Adjustable Voltage Supply, which needs 40 W or more. Fermi45 delivers it: 50% in about 20 minutes.
Fermi30 is matched to the iPhone 16 series, and Fermi65 to a MacBook with an iPhone beside it.

Two ports that share intelligently.
Fermi35, Fermi45 and Fermi65 carry two USB-C ports. Plug in one device and it takes the full output. Plug in two and the adapter negotiates a split with each, for example 25 W + 20 W on Fermi45 or 45 W + 20 W on Fermi65.

Using it well
Match the cable to the adapter: a 60 W (3 A) USB-C cable for Fermi30 to Fermi45, and a 100 W (5 A) cable to draw the full 65 W from Fermi65. Push the adapter fully into the socket and keep it clear of bedding while it works.
