It starts, as so many tech frustrations do, with a drawer. A drawer full of chargers — one large black brick for the laptop, a skinny one for the phone, a USB-A cube from 2017 that nobody's quite sure what it belongs to, and a cable that fits nothing anyone currently owns. If that drawer exists in your house or office, this article is for you.

The Anker 737 GaNPrime 120W charger is a single, palm-sized plug that replaces most of that drawer. It costs around £89, which sounds like a lot for a charger — until you think about what you're actually replacing.

What Is It, Exactly?

It's a GaN (gallium nitride) charger. GaN is the technology that's quietly replaced old-fashioned silicon inside modern chargers, allowing them to be dramatically smaller and run much cooler while delivering the same — or higher — power output. The Anker 737 packs 120W of total output into a block roughly the size of a large matchbox. It has three ports:

  • Two USB-C ports (the main one delivers up to 100W on its own)
  • One USB-A port for older cables and devices

Plug in just your laptop via USB-C and it gets the full 100W — fast enough to charge most modern laptops at full speed or close to it. Add your phone on the second USB-C port and the charger automatically negotiates how to share the power intelligently, without you having to think about it.

Who Is This Actually For?

It's genuinely useful for three types of people:

  1. Home workers with a desk setup. One charger handles everything on the desk. Tidier, simpler, one plug socket used instead of three.
  2. Anyone who travels with a laptop. Swapping out two or three chargers for one compact block makes a real difference in a bag. Hotels typically have one plug socket somewhere inconvenient — this means you're not choosing between charging your laptop or your phone.
  3. Small businesses with mixed kit. USB-C is now standard on most Windows laptops, all modern MacBooks, most Android phones and iPads. If your team uses a mix of devices, one of these on each desk is cleaner and cheaper than a collection of proprietary bricks.

It is not for people who have one device and are happy with the charger that came in the box. If your laptop came with a 65W USB-C charger and you only ever charge the laptop, you don't need this. But most people, if they're honest, are charging more than one thing at a time.

What It Does Brilliantly

The speed is the standout thing. On a MacBook Pro 14-inch or a modern Dell XPS, this charger keeps up — even under load. Many third-party chargers claim high wattage but throttle in real use; this one doesn't, in our experience. It charges a phone at the same time without either device complaining.

It also runs cool. Traditional laptop chargers get warm enough to be uncomfortable to touch. The 737 gets mildly warm — noticeably less so. That's the GaN technology at work, and it's not just about comfort; a charger that runs cooler tends to last longer too.

Build quality is solid. Anker are one of the few third-party brands that take safety certification seriously, and this charger carries all the relevant marks (CE, UK CA). It doesn't feel like something you'd find in a cardboard box on a market stall.

Finally — and this matters more than it sounds — it folds flat. The plug pins fold in, so it doesn't snag in your bag or poke holes in anything.

What It Doesn't Do

A few honest caveats worth knowing before you buy:

  • It doesn't come with cables. You'll need USB-C to USB-C cables, ideally rated for 100W (look for "5A" on the cable or "100W" in the listing). Most USB-C cables people already own are only rated for charging phones. Worth checking before you assume.
  • It won't charge gaming laptops at full speed. High-end gaming machines often want 180–240W. This charger will charge them, but slowly — fine overnight, not ideal during a session.
  • It's USB-C only for the high-power ports. If your laptop still uses a barrel connector (the round magnetic-style plug), you'll need an adapter, and power delivery through adapters is variable. For older laptops, the original charger is still the right answer. If you're unsure whether your laptop supports USB-C charging, it's worth asking someone who can check before you spend the money.
  • One USB-A port. Fine for most people, but if you're still running a lot of older USB-A devices — older Kindles, some older phones, certain accessories — you might find one port limiting.

Honest Verdict

At £89, the Anker 737 GaNPrime is priced fairly for what it is — a genuinely premium, well-built charger that does what it claims. It's not cheap, but it's not trying to be. If you're the sort of person who charges a laptop and at least one other device regularly, this will almost certainly be the most-used thing on your desk within a week of buying it.

The drawer full of chargers doesn't disappear entirely — there'll always be one ancient cable lurking in there — but it shrinks. And shrinking that drawer, even a little, is a quiet but very real improvement to your day.
