Following in the footsteps of Anker, accessory makers Griffin and Aukey are at CES 2020 in Las Vegas this week to show off new portable wall chargers based on a material known as gallium nitride, or GaN. In short, GaN allows semiconductor components to be shrunk down, leading to smaller chargers.

Griffin has three new PowerBlock chargers based on GaN, including a 30W option with dual USB-C ports for devices like an iPhone or iPad, a 45W option with a single USB-C port for devices like a 13-inch MacBook Pro, and a 96W option with a single USB-C port for devices like the new 16-inch MacBook Pro.

Griffin PowerBlock Range
The chargers are anywhere from 11 to 57 percent smaller than non-GaN versions, depending on the wattage, according to Griffin. All of them support USB-C Power Delivery for fast charging, and they all have folding prongs.

Griffin says the new PowerBlock lineup will be available in the second quarter of 2020, with prices ranging from $49.99 to $79.99.

Aukey is also launching a new line of GaN-based chargers in the second quarter of 2020. Full details and pricing have yet to be disclosed, but based on the image below, the so-called Omnia Series will include at least five portable chargers with various combinations of USB-C and/or USB-A ports.

but better technology for charging where it’ll save longevity of battery health.
I've seen no reports that GaN-based chargers affect battery health in any way. Do you have a source/study for that claim?
