What to know first
- Four ports total: 3 USB-C plus 1 USB-A.
- Up to 150W total output across the charger, with up to 100W from a single USB-C port.
- Not foldable, so it’s more “bag charger” than “pocket charger.”
- Supports USB-C Power Delivery style charging profiles up to 20V, plus PPS support is listed.
- Wide input range (100 to 240V) for use in many countries with a plug adapter.
What the Anker 747 Charger (GaNPrime 150W) is
The Anker 747 Charger (GaNPrime 150W) is a multiport wall charger designed to power several devices from one outlet. It has four ports total: three USB-C ports and one USB-A port.
Its headline spec is total output up to 150W. In plain terms, that’s enough capacity to run a laptop charger level of power while still leaving room for smaller devices like a phone, earbuds, or a tablet, depending on what you plug in and how the charger allocates power.
This model is part of Anker’s GaNPrime lineup. The point of GaN-based chargers is typically to deliver higher power in a smaller charger than older designs, while managing heat and efficiency better. The 747 is still a substantial brick, but it’s meant to replace multiple separate chargers.
Why it stands out
The big reason to buy the Anker 747 Charger (GaNPrime 150W) is port flexibility without giving up laptop-level charging. You get three USB-C ports (the ports most modern laptops, tablets, and phones want) plus a USB-A port for older cables and accessories.
A single USB-C port can output up to 100W (on USB-C1, USB-C2, or USB-C3). That matters because many laptops can charge over USB-C at high wattage, so you can use this as your main laptop charger instead of packing the manufacturer brick.
When you plug in more than one device, the charger shares power across ports up to 150W total. Anker lists combinations like USB-C plus USB-A up to 100W + 22.5W, and three USB-C ports sharing up to 150W. For everyday carry, that’s the whole appeal: one outlet stop can top up everything you’re carrying.
What it is like to own
In daily use, this is a “leave it in your backpack” charger. It’s not foldable, so it won’t pack as flat as some smaller travel chargers, but it’s still a single item to grab instead of juggling multiple bricks.
The workflow is straightforward: plug it into the wall, then plug in up to four devices. If you’re charging a laptop plus smaller devices, you’ll typically want the laptop on a USB-C port and everything else on the remaining USB-C or the USB-A port.
Because it’s a shared-output multiport charger, what you plug in affects what each device gets. That’s normal for this category. The upside is fewer chargers and fewer outlet hunts. The downside is that you’re managing one shared power budget instead of giving every device its own dedicated brick.
What to know before you buy
First, the plug is not foldable. If you’re trying to build a super slim pocket kit, that matters. For most people, it’s still a good backpack or desk charger, just not the flattest option.
Second, don’t confuse “150W total” with “150W to one device.” A single USB-C port tops out at 100W. The 150W number is the combined maximum across ports, so if you’re charging multiple devices at once, the charger is dividing that total output.
Finally, the USB-A port is capped lower than USB-C (22.5W max). It’s great for older cables and accessories, but your fastest charging for modern devices will generally come from USB-C.
The specs that matter
You can charge a laptop and still have ports left for a phone, earbuds, or a tablet, all from one wall outlet.
This is the overall power budget. It’s what makes the charger viable as a single-brick solution for a laptop plus smaller devices.
A 100W USB-C port is in the range many USB-C laptops can use, so this can replace a typical laptop charger for a lot of setups.
USB-A is handy for older cables and accessories, but it’s not the port you’d pick for high-power laptop charging.
It can work in many countries with the right plug adapter, which is useful for study abroad or travel.
It’s compact enough for a bag, but it’s still a noticeable brick compared with tiny single-port phone chargers.
It’s not weightless, but it can still reduce overall carry weight if it replaces multiple separate chargers.

Anker 747 Charger (GaNPrime 150W) FAQ
How many devices can the Anker 747 Charger (GaNPrime 150W) charge at once?

Can the Anker 747 Charger (GaNPrime 150W) charge a laptop?
Yes, it can. Each USB-C port can output up to 100W, which is laptop-charger territory for many USB-C laptops. Your laptop also needs to support charging over USB-C.
Is the Anker 747 Charger (GaNPrime 150W) good for travel?
It can be, especially if you want one charger for multiple devices. It supports 100 to 240V input, so it can work internationally with a plug adapter. The main travel downside is that it’s not foldable.
Does the Anker 747 Charger (GaNPrime 150W) support fast charging?
It supports common USB-C power profiles up to 20V and lists PPS support. In practice, fast charging depends on your device and cable, and how the charger is splitting power when multiple devices are plugged in.
What’s the difference between 150W total and 100W per port on this charger?
150W is the maximum the whole charger can deliver across all ports combined. 100W is the maximum any single USB-C port can deliver to one device. If you plug in multiple devices, they share the 150W total.
Should you buy the Anker 747 Charger (GaNPrime 150W)?
Buy the Anker 747 Charger (GaNPrime 150W) if you want to simplify your bag and your outlet situation. The combination of three USB-C ports, one USB-A port, and up to 150W total output is exactly what you want when you’re charging a laptop and a couple of smaller devices in the same day.
Skip it if your life is mostly phone-only charging, or if you care more about a fold-flat plug than having a high-output, four-port setup. For everyone else, this is a practical way to replace a pile of single-device bricks with one charger you can rely on.
