What should I do if low-current devices cannot be fully charged?
This charger supports low-current devices from mainstream brands (e.g., Apple, Samsung, Huawei). However, for niche devices like electric shavers or hearing aids, we recommend using the USB-A port alone for a better charging experience.
What should I do if the charging icon on my MacBook is delayed?
When charging a MacBook with a third-party wall charger, you may see a plug icon first. After about one minute, it will switch to a lightning bolt. This is normal and charging continues normally.
Why is it charging slower than expected or why doesn’t the charger reach 70W?
Charging speed varies depending on battery level, temperature, and how the device is being used. Maximum output is usually reached when the battery is low and the screen is off. This is normal and can occur even with the original charger.
Why does my laptop charge slower than expected?
A “slow charging” notification can appear if your laptop’s power requirement exceeds this charger’s maximum C1 port output of 70W. For best performance, please check your laptop’s original charger to confirm its rated power.
Power Your MacBook at True 70W Speed: Each USB-C port delivers 70W max of power—enough to charge a 14-inch MacBook Pro (2024) from 0 to 50% in 35 minutes. Compared to a standard 65W charger, it offers faster performance and better compatibility with the latest M4 models.
Mini Size and Travel-Friendly: At just 2.09 × 1.68 × 1.24 inches, the charger is 41% smaller than a standard 70W USB-C charger—making it effortlessly portable. Slip it into a pocket, handbag, or travel pouch without taking up valuable space, so you can stay powered up wherever you go.
Fast Charging That Stays Cool: With TÜV Rheinland certification and ActiveShield 4.0 thermal monitoring, surface temperatures measure up to 50°F (10°C) lower than international safety benchmarks for charging devices.
Elegance in Every Charge: A textured shell, glossy finish, and premium metal frame create a clean, modern look that blends seamlessly with your workspace or travel setup.

Charges so fast I’m Pretty Sure it Bent Space-Time
I bought the Anker Nano 70W charger because I needed something powerful. What I didn’t expect was a tiny brick of pure charging wizardry. This thing is so fast I’m convinced it siphons energy directly from the sun. I plugged in my phone and blinked — suddenly it was at 80%. I don’t even think I can recover that quickly after a nap.The three ports are a lifesaver. I can charge my phone, my tablet, and my laptop all at once, and it doesn’t even break a sweat. Meanwhile, I’m over here struggling to carry all my groceries in one trip. The charger is clearly the superior lifeform.It’s also ridiculously compact. How Anker fit 70 watts of power into something this small is beyond me. I’ve seen muffins bigger than this charger. And unlike muffins, this won’t crumble under pressure.If you want a charger that’s fast, reliable, and possibly powered by ancient alien technology, this is the one. Anker really said, “What if we made a charger that could jump‑start your productivity and your entire household?”Highly recommended. My devices have never been happier — or more afraid.

Perfect compact 70w charger. More than enough for a laptop and phones.
Great 70w output charger. I bought this to carry versus my MacBook Pro charging brick which is much heavier and larger. This is compact and lightweight and perfect for a small bag or your briefcase. It is versatile and easy to use with two USB-C and one USB-A ports making it very functional for multiple devices. i used it for 5 hours straight powering my MacBook Pro and the heat level remained minimal which was great given the fact that it is so compact and delivering 70w of charging power. As a bonus, it comes with a USB-C cord as well. I used to buy whatever was the cheapest product was for charging devices but found you get what you pay for. I have since grown to trust Anker products and buy them often for their quality, price and broad product line. Definitely a trusted brand and one i search out first in my household.

Another W from Anker’s Nano series
What can I say, Anker delivers once again. The Nano line of hardware is by far the best value you will find if you want to buy Anker products due to their reliability and reputation. The Prime stuff is cool and powerful and premium looking, but Nano is cheaper while also delivering consistent power output, solid heat-dissipation, and fast charging capabilities for all but the most high-end devices. This is such a steal for what you get. 70W in a very small package is exactly what the average tech-savvy user realistically needs. I can fast charge my MacBook air fully, I can fast charge my phone and watch while also using my laptop on power. Don’t let the size fool you (and yes, it’s very small for a 70W 3-port charger), it’s very capable.

Reliable and Fast — Great for Travel
This charger works exactly as expected. It delivers fast, consistent charging and is a great option for travel thanks to its compact size. Anker continues to be my go-to brand for all my charging needs because their products are dependable and well-made.

Great Charger for Multiple Devices
This is a great charger block. We keep it plugged in on a kitchen counter so we can quickly charge when needed. It has two fast charge USB-C ports and one slow charge USB-A port. It’s easy to use and access because the ports face the same direction. Feels like it’s good quality and looks nice. The fast charging ports do charge quickly. Where we keep it plugged in, we can’t see the block (behind stuff), so we use different types of wires for the different ports — we use a textured wire for the fast charging ports, and a smooth wire for the slower port — so we know what to expect when charging. Works great so far. We use it for iPhones, Androids, and iPads.

Solid Performer. Quality feel.
I really like Anker products and this one is no exception. This is a solid performer. Nicely compact, with folding plugs. Quality feel and is a bit heavy, but to be expected for a 70W charger. Fits nicely in my computer bag.Charges my Dell computer when I don’t have the Dell charger with me. However, when my iPhone and computer are plugged in at the same time, the charging capacity for the computer is less. Still not an issue, though.I often have two iPhones charging at the same time and it performs well.

Great quality and fast charging
This charging block charges my devices significantly faster than a regular charger or when it’s plugged directly into the outlet. I have not noticed it getting hot at all since I started using it. The charging time for my iPhone, iPad, and my MacBook Air have all been cut down by almost half. I think the only thing I didn’t notice a difference with was with my Apple Watch, but that may be due to the cable. It’s easy to use and I like that it has two USB-C ports and a USB-A port so I can charge multiple devices at once. I also like the included bio-braided cable— it’s so much more durable. I happened to get this on price drop of $40, so it’s a great deal.

Great for Travel…leave your other chargers at home
First of all I’d like to first say that over the years I’ve found Anker products to be number one in quality and durability, including chargers and cords. This charger is ideal for travel because of its small size replacing the need for multiple charging devices including my MacBook Pro charger. Since I’ve just purchased it I can’t speak of it’s reliability but because it’s an Anker I feel confident that Ill be using it a long time.

I have been using the Anker Nano USB charger for a few days not and it has never failed. It charges faster than the Iphone adaptor i have been using. I even tried other cheaper ones from local shops but this takes the prize. It recognizes all wires i plugged in it. I found a few Anker adaptors on sale this month so if you can get this one on a discount it would be even better.

Anker products never disappoint and this product is no exception. It is much smaller than expected and still producing 70W of power. Very satisfied with this purchase.

Charges fast, stays cool, and does exactly what it promises. Anker never misses. This is one of those gadgets you buy once and forget about because it never gives you problems.

This is a small, compact charger that doesn’t get hot while charging. I love it as a USB-A connector for older devices. The plug stays securely in the wall.
