A good fit for a desk with one laptop and one phone, and a striking one. If your laptop shipped with a charger above 65W, expect it to charge more slowly on this one.

ข้อดี

Three ports in one GaN body
Folds for travel
US, UK and EU plugs in the box

ข้อเสีย

65W is shared across all ports
Per-port power split not listed by the maker

เหมาะกับ: One laptop and a phone, at home or on the road
ข้ามไปถ้า: Your laptop came with a charger rated above 65W

สเปกหลัก

Output: up to 65W total
Ports: 2 x USB-C, 1 x USB-A
Input: 110–240V
Technology: GaN

What it is

The Alpha65 is a three-port wall charger from GravaStar built on gallium nitride (GaN). It is in our Showcase. This review reads the maker's specs and the USB-IF's Power Delivery figures. It is not a bench test.

The specs

Output: up to 65W in total
Ports: two USB-C and one USB-A
Input: 110–240V
In the box: US, UK and EU plug adapters

GravaStar says GaN makes the charger 50% smaller than a traditional charger of the same power, and lists protection against overcurrent, overvoltage and heat. The body folds for travel.

What 65W covers

65W is the total across all three ports, so a laptop and a phone share it when both are plugged in. GravaStar's page does not list how the power splits between ports, so check the rating of the charger that came with your laptop before you make this your only brick.

For scale: USB Power Delivery topped out at 100W, over 20V and USB-C cables rated at 5A, until Revision 3.1 raised the ceiling to 240W with new 28V, 36V and 48V levels. A 65W charger sits well inside the older range.
