The Anker 737 GaNPrime 120W is the charger we reach for when we need to power a laptop and two phones from a single wall socket without compromise. Three ports, true 120W total output, and intelligent power distribution that actually works — not theoretical marketing specs but measured under load with a USB-C power meter.
The power distribution is the differentiator
Most multi-port GaN chargers advertise their total wattage but silently downgrade each port when you plug in more devices. The 737 negotiates PD 3.1 and PPS dynamically — plug in a MacBook Pro 16 alone and it pulls 96W; plug in an iPhone 15 Pro on the second port and the MacBook drops to 90W while the iPhone pulls 27W. No other 120W charger we’ve tested redistributes this cleanly.
The foldable plug and size
At 65×65×32 mm and 195g with a foldable plug, it’s smaller than the 140W Apple brick and lighter than the UGREEN Nexode 140W. It fits in a laptop sleeve without rattling.
Who should skip it
If you only charge one device at a time, save $40 and get the Anker Nano 511 20W or the 100W Anker 736. If you need 140W+ for a MacBook Pro 16 M3 Max under sustained load, step up to the UGREEN Nexode 140W.
Bottom line: Best 120W GaN charger for powering a laptop + 2 phones at once. Worth $85.
