GaN charger manufacturer — Kestner Supply

Q: What wattages and port counts do your GaN chargers cover?

30, 65, 100, and 140 W with 1 to 4 ports (USB-C and USB-A mix), including PD 3.1 EPR on the 140 W units for laptops.

Q: What is GaN and why does it matter?

GaN (gallium nitride) switches faster than silicon, so the charger runs cooler and packs the same wattage into a smaller, lighter housing — the reason a 100 W GaN unit is a fraction of the size of a legacy brick.

Q: Can you build a retail-ready GaN charger to our brand?

Yes. Custom housing, colorway, port mix, retail packaging, and logo — white-label to your program.

Q: What certifications do your GaN chargers carry?

UL 62368-1, DoE Level VI, and FCC Part 15 B, verifiable by file number.

Q: Can I choose the country of origin?

Yes — built in Vietnam or China on one drawing set, origin documented per unit.
