140W USB C Charger, Anker Laptop Charger, 4-Port Multi-Device Fast Charging, Advanced GaN Power Adapter, Intuitive Touch Controls, Compatible with MacBook, iPhone 17 Series, Samsung, Pixel, and More

I bought this charger a few weeks ago, and chose it based on the good reviews, its power output, and significantly the brand name, which I have used and trusted for many years. First impressions were of its nice, simple design. I can’t really call it petite, as it’s about twice the size of a simple, single-port charger, but they have managed to keep it slender and elegant (due largely to its boasted GaN technology, which I’ll mention later), and considering its huge power output, I couldn’t really expect it to be any smaller. The handy mains plug pins fold out easily and feel spring-loaded to hold their position. The display is at the outer, opposite end, and the ports are all on the underside. It’s worth bearing in mind that this is the type which plugs directly into the mains socket, rather than a plug and cable to the charger, which may be a consideration for the following reasons: 1. If you would prefer a charger you can place a distance away from the socket, such as on a desk or bedside table. 2. If you need to use a mains socket with limited clearance beneath it. Because all four ports are located on the underside of the charger, a gap of a couple of inches is needed to accommodate the plug and grommets at the end of the USB cables. I have just one mains socket in my house like this (see photo’s above), and it’s in my kitchen so not really an issue for me at all. A possible solution to this could be to buy small L-shaped end connectors, which are available fairly cheaply, but for most households this scenario is pretty unlikely anyway. The product description states it's an 'Advanced GaN power adapter'. GaN, which stands for Gallium Nitride, is a newer semiconductor material that is replacing the traditional silicon used in older chargers. This means that chargers can be made smaller relative to their wattage, and it also helps the charger run cooler, so GaN technology is a major reason why this charger can be so compact in relation to its 140 W power. You may notice IQ3 printed on it (PowerIQ 3.0 technology). This is just Anker's own bespoke brand term, not a generic, scientific abbreviation. They don’t define what the letters ‘I’ and ‘Q’ actually stand for, but describe it as “Anker’s proprietary fast‑charging technology, which intelligently identifies your device to deliver the fastest possible charge”. This applies to all three USB-C ports, with the USB-A port using the older IQ2 version. It also supports PD 3.1, which is the latest industry-standard USB charging system (not an Anker invention). Unlike the older PD 3.0, which was capped at 100 W, PD 3.1 raises the limit to enable this charger’s full 140 W output at 28 Volts and 5 Amps (28 V × 5 A = 140 W). In practice, this means it can power large devices such as laptops while still remaining compatible with lower-powered gadgets like phones. The way it shares its power changes by the second, adjusting based on the needs of your connected gadgets. The charger provides a TOTAL 140 W of power. This power is then shared among its four ports: • Two USB-C ports: Each up to 140 W individually. • One USB-C port: up to 40 W. • One USB-A port: up to 33 W. The charger doesn't just split its power evenly; it communicates with each connected device to determine how much power it needs. A big factor in this is the device's battery level: • Low Battery %: When a device’s battery is low (e.g. under 50%), it will draw maximum power to recharge quickly. This is the true “fast charging” phase often highlighted by advertisers — which, as you may have noticed, is why they quote “0–50% in xx minutes”, rather than 0–100% which would be greater than the sum of its parts. • Higher battery %: As the battery fills up, the device's internal system will reduce the amount of power it requests from the charger to protect the battery’s lifespan. The charging rate will gradually reduce, as you’ll notice on the charger’s display. • Almost Full Battery: Once a device is nearly full, it will only draw a very small amount of power to top up the battery, probably showing in single figures on the charger’s screen. Because of this type of communication, the charger automatically prioritises and allocates power where it's needed most. For example, if you connect a laptop with a 10% battery and a phone that is 90% charged, the charger will dedicate a larger portion of its 140 W total to the laptop. As the laptop's battery fills up and it requires less power, the available wattage can then be used for other connected devices. The charger continuously adjusts this in real-time, never exceeding the total 140 W limit. In fact, seeing the full 140 W displayed will probably be a rarity, unless you have several large gadgets charging simultaneously, or a high-end laptop such as the MacBook Pro, and even then only while their batteries are at a low percentage. When charging MULTIPLE devices, the ports are prioritised by output in this order: C1 > C2 > C3 > A1. Anker’s full specifications detail the various scenarios below (scroll down a couple of paragraphs if this is too much info): Two ports active • C1 + C2: 70 W + 70 W (total 140 W) • C1 or C2 + C3: 100 W + 40 W (total 140 W) • C1 or C2 + A: up to 100 W + 33 W (total 133 W) • C3 + A: 12 W + 12 W (total 24 W). Three ports active • C1 + C2 + C3: 65 W + 45 W + 30 W (total 140 W) • C1 + C2 + A: 65 W + 45 W + 30 W (total 140 W) • (C1 or C2) + C3 + A: 100 W + 12 W + 12 W (total 124 W). Four ports active • C1 + C2 + C3 + A: 65 W + 45 W + 12 W + 12 W (total 134 W. Yes, slightly below 140 for safety management to avoid overloading). Phew…Therefore, when ALL four ports are in use, try to connect in the order of this example as a rough guide for best results: • C1 – high-power laptop • C2 – medium device (smaller laptop or tablet) • C3 – smartphone • A1 (USB-A) – Small gadgets (watch, earbuds etc.) When charging just ONE device, always use port C1 if possible. In reality, if only one or two small devices are connected, they will most of the time receive their maximum dose of wattage anyway. For example, iPhone 15/16 standard models can charge at a maximum of 20 W. This capped threshold is built into the phone's software to protect the long-term battery lifespan, and probably only then hitting this limit while the battery is lower than 50%. All this makes sense when viewed in detail on the display. There are four different screens, in this order: • Current total power output • List of all ports with respective live wattage • Charger temperature status • Total time used (hours from day one) You cycle through these by touching the lower part of the screen, highlighted with a circle. The screensaver kicks in after 60 seconds if no further contact is made, turning off to black while charging continues as normal. You can also rotate the direction of the display to up, down, left or right by long-touching it for 2 seconds, which is handy if it’s plugged in at a non-standard angle, although I’ve sometimes triggered this with accidental touches. The temperature display, which Anker have trademarked ActiveShield™ 2.0, refers to the charger itself, not the connected device(s). It doesn’t show degrees Celsius, but rather one of three states: • Excellent • High performance • Cooling mode Which is a fancy way of saying warm/warmer/warmest respectively. It still works in cooling mode, just at a slower rate, known as “throttling”, to avoid overheating until its temperature reduces. Devices like iPhones also regulate their own temperature during charging, but this info isn’t shared with the charger since USB-PD only negotiates power; each handles its own safety independently, which is reassuring to know. All good so far. -Pros: • Extensive, live information display • 140 W total power • Foldable plug pins • USB-C cable included • Trusted brand -Cons: • Not cheap (£89.99 at the time of purchase) Overall, this is an excellent charger. I'm not keen on the term "future-proof," because it's always a matter of time before it becomes untrue, but this gadget certainly feels "future-resistant." It's about as state-of-the-art as anything you can buy at the moment. Its bells and whistles are not just cosmetic novelties; they are genuinely helpful and reassuring, providing real-time information on exactly what is happening for all connected devices and even for the charger's own temperature. It's not the cheapest option, and if you usually charge just one device at a time it may be an extravagance, but if it's within your price range, and you need to charge multiple devices simultaneously, I would certainly recommend it, so it's a full five stars from me. Thanks for reading, I hope you found this review helpful.

Really love Anker products and super happy with this charger, I love the real-time energy throughput display and the ability to charge 4 devices at once. Works well for USB-C power driven laptops. The charger is good value for money, nice and small, not too heavy and easy to take when travelling abroad. Saves you having to bring 4 chargers

I purchased this item to charge various camera equipment, paranormal equipment, lighting and also boost my laptops battery. First impressions. I really like the way the pins fold neatly away. It means when placed in a bag or case the chance of damage is greatly minimised. Makes it great for portability. The build quality seems fantastic. The unit feels solid and has the standards you would expect from Anker. With 3x USB C ports and 1x USB A port it’s got options to keep it functional but not overcomplicated with things you are unlikely to use. The intelligent charging seems to work well and I find it throws the power where it’s needed well! I do appreciate the display showing the wattage draw of each item plugged in. It’s quite surprising what some units use, but likewise you will be surprised at how little others use. It’s great for gauging what items are expensive/power hungry to charge if you’re energy conscious. The unit measures and can display the heat in realtime. It does get hot under heavy load but not to any level I would be concerned. It seems heat dissipation is quite good on the unit. All things considered it’s a great unit, good build quality and works very well. It’s not what I would consider cheap but it does go above and beyond your standard charger. I expect likewise this will last well. I would gladly buy again if given the chance.

Very good item. Charging super fast 2.0 two devices in the same time. USB A port is not fast but it is working fine. I didn't tried to see if it is able to charge my ASUS laptop but I will try soon. After a few weeks, no complain at all.

This charger is really impressive. The build quality is solid and it feels very premium. Charging speed is excellent — it charges my MacBook Pro 16” M1 Max perfectly without any issues. Even under heavy use, it keeps the battery topped up smoothly. I also like the multiple ports, which make it very convenient to charge other devices at the same time. It’s compact for the power it delivers, so it’s great for travel as well. Overall, I’m very satisfied with this purchase and I would definitely recommend it to others.

A fantastic charger for everything in my house
