Anker's new compact GaNPrime chargers put out up to a whopping 150W

Thanks to Gallium Nitride (GaN) With technology, chargers have become more powerful while at the same time shrinking. The latest example of this trend is the new line from Anker GaNPrime chargers with next-generation GaN 3 technology, which the company says is even more energy efficient. GaNPrime products are up to 53% smaller than silicon laptop chargers, says Anker, and with their higher power output, "a single GaNPrime device can charge up to four or even six devices at once, depending on the charger."

Most of the new GaNPrime chargers are available now, including the 737 Charger (120W)but the 747 Charger (150W) will be shipped in August. While I like the chargers themselves, I can't say I'm a fan of the products' names, which is a bit confusing considering previous generation models with similar names.

I've received early samples of both the 737 Charger and 747 Charger, and I briefly assume that the big thing GaN 3 - or GaNPrime, as Anker calls it - offers is a slightly increased maximum power output, up to 150W Better energy efficiency when converting AC to DC (93.6% vs. 92% for GaN 2). You also get some economies of scale. For example the new one 747 Charger (150W) Appears to be similar in size to Anchor 100W 736 USB-C Charger ($85), or at least not much bigger. Meanwhile, the 737 Charger (120W) appears to be only about 20% to 25% more powerful than Anker's 65W 737 USB-C Charger ($60) that uses GaN 2 technology. (The new 65W 735 charger uses GaN 3 but appears to be similar in size to the 65W 737).

There are a few other key features that Anker highlights. The first is PowerIQ 4.0, which gives the new chargers the ability to recognize which device you have plugged into the charger and distribute optimal charging power to each device, giving priority to the device with the lowest battery level. Second, Anker is touting Active Shield 2.0, a thermal sensor feature that monitors temperatures while charging more frequently than the previous generation.

Here's a look at the full range of chargers with prices and availability.

Similar in size to the company's previous 736 USB-C charger (100W), Anker's new 747 GaNPrime charger (150W) features three USB-C ports and one USB-A port.
