A practical buying guide to the Anker 737 Prime Charger 120W: what its three ports can realistically power, who should buy it, and when a smaller GaN charger or power bank makes more sense.
Quick answer
The Anker 737 Prime Charger (120W, 3 Ports, GaN) is worth buying if you regularly charge a laptop and phone together from one wall outlet and want a compact GaN design instead of carrying two chargers. Its 120W total output spreads across three ports, so it is a desk and travel hub rather than a single-device speed charger. If you mostly charge a phone and earbuds at home, a smaller Nano Charger costs far less and does the same daily job.
What the three ports realistically cover
Three ports matter most when your devices have different power needs. A 120W total budget is generous for a laptop plus a phone, but it is not three full-speed laptop ports at once. Before buying, add up the wattage your devices draw and decide which one deserves the largest share. If your laptop is the priority, keep it on the highest-output port and let the phone share what remains. If two laptops are your normal load, this charger will split the budget and slow both down.
Where a 120W GaN wall charger earns its place
GaN technology is the reason a 120W charger can stay small enough to live in a bag pocket. That compact size is the real upgrade for frequent travelers who currently pack a laptop brick plus a phone charger. One wall charger replaces two, and you keep the same outlet for both. The trade-off is that a multi-port charger is a shared resource: the more devices you plug in, the less power each one receives. Treat the 120W rating as a total budget, not a promise for every port.
When a Nano charger or power bank beats the 737
A 45W Nano Charger with a USB-C to USB-C cable is the better call for phone-first buyers, students, and anyone who wants a second charger for a bag. It is smaller, cheaper, and already includes a cable, so there is nothing else to buy. A 35W Nano Charger with a built-in retractable USB-C cable goes further on convenience because the cable cannot be lost, though it is not designed for laptop-level loads. If your problem is charging away from an outlet rather than at one, skip wall chargers entirely and look at a high-capacity power bank such as the 737 Power Bank (24,000mAh, 140W, 3-Port).
Travel and desk setup checks before you buy
Check three things before committing. First, confirm your laptop charges over USB-C, because a 120W GaN wall charger only helps devices that accept USB-C power. Second, count your simultaneous devices: two is comfortable, three is workable, and four means adding a second charger. Third, decide whether you need a cable in the box. The 737 Prime Charger is sold as the charger itself, so plan for USB-C cables separately. If those checks pass, this is a buy-once charger for a desk or carry-on. If any of them fail, a Nano charger or a power bank will serve you better.
Decision rules: which charger fits your setup
- Choose the 737 Prime Charger if you charge a laptop and phone together at one outlet: Its 120W total output and three ports replace two separate chargers in a single compact GaN body, which is the main reason to pay more. Buy it when one outlet needs to serve a laptop plus at least one smaller device.
- Choose a Nano Charger if your heaviest device is a phone or tablet: A 45W Nano Charger with a USB-C to USB-C cable covers everyday USB-C devices and includes the cable; a 35W Nano Charger with a built-in retractable cable removes cable clutter but is not aimed at laptop loads. Spend less and carry less when laptop wattage is not part of your day.
- Choose a power bank if your charging happens away from outlets: The 737 Power Bank (24,000mAh, 140W, 3-Port) covers travel, commuting, and long days out, while a wall charger only works where power is available. Match the tool to the location: wall charger at a desk, power bank in a bag.
- Plan cables and port priority before checkout: The 737 Prime Charger is the charger only, so budget for USB-C cables, and assign the highest-output port to your laptop when several devices are connected. A charger plus the right cables and port order is the setup that actually delivers the rated speed.
Product facts
- Anker 737 Prime Charger (120W, 3 Ports, GaN): The Anker 737 Prime Charger delivers up to 120W of power through three ports, using GaN technology for efficient charging in a compact design. The 120W figure is a shared total across all three ports, so a laptop plus phone setup works well while three high-draw devices will split the budget and charge more slowly.
- 737 Power Bank (24,000mAh, 140W, 3-Port): The Anker 737 Power Bank (24,000mAh, 140W, 3-Port) is a high-capacity portable charger designed to keep your devices powered on the go. If your real problem is charging away from a wall outlet, a power bank solves it; a wall charger like the 737 Prime only helps where you can plug in.
- Nano Charger (45W) with USB-C to USB-C Cable: The Anker Nano Charger (45W) with USB-C to USB-C Cable offers a compact and efficient way to power your compatible devices and includes a USB-C to USB-C cable for immediate connectivity. For phone-first buyers who do not need laptop wattage, this is the lower-cost option and it arrives ready to use without buying a separate cable.
Who the 737 Prime Charger is for
Best for
- Laptop owners who want one compact GaN wall charger for a laptop and phone at the same outlet

Not for
