When you’re constantly on the move, the last thing you want is to lug around a bulky power bank. That’s where the Anker Nano 5K MagGo Slim comes in. This ultra-thin powerhouse promises to deliver reliable power without the added weight, and after putting it through its paces, here’s my full take on whether it lives up to the hype.

First Impressions: Ultra-Thin Yet Surprisingly Durable

At first glance, the Anker Nano 5K MagGo Slim looks like it might be some sort of charging pad, not a full-fledged power bank. Measuring just 0.34 inches thick (about as thin as a standard iPhone), it immediately stands out in terms of portability. The size is almost too compact, but once I held it in my hands, I realized that it’s much sturdier than I expected.


The matte finish feels soft but premium, offering a good grip despite its slim profile. What’s impressive is how Anker has managed to pack a 5,000mAh capacity into a device this thin, while maintaining solid build quality.


The MagSafe compatibility ensures that it sticks to the back of my iPhone without any fuss, and the USB-C port, power button, and 4-LED battery indicator are all integrated without adding bulk. This is a power bank designed for those who need something portable but don’t want to sacrifice functionality.
Charging Performance: Quick, Efficient, and Reliable
I was skeptical about how well a power bank of this size could actually perform, but after testing it, I’m impressed. Despite its compact design, the Anker Nano 5K did not disappoint when it came to charging my devices.

During a test with my iPhone 15, the Qi2 wireless charging topped my phone up from 60% to 80% in just 30 minutes, and I had it at 100% in just under an hour. The charging speed is on par with much thicker power banks I’ve used, and the fact that it supports MagSafe means it magnetically attaches to the back of my iPhone, offering quick, hassle-free charging.
I also gave the USB-C wired charging a spin. Using the 20W USB-C output, I was able to juice up my phone quickly even when I was on the go. While the 5K MagGo Slim is not meant for long-term, heavy-duty charging, it provided just enough power for my day-to-day use, easily getting me through a full day of work without issues.
Real-World Use: Convenient, Pocket-Sized Power
What I really loved about the Anker Nano 5K MagGo Slim was how easy it was to use throughout my day. Whether I was running errands or at a coffee shop, it slid effortlessly into my pocket, and when my phone’s battery started running low, I just stuck the power bank on the back of my iPhone, and boom—instant charge.

One standout moment was when I left the house with only 30% battery on my phone. By the time I got to an event later that evening, my phone was at 80%, and I barely felt the weight of the charger in my bag. It was like carrying a credit card with the charging power of a full-size power bank, which, honestly, feels like magic.
Who Is It For?
The Anker Nano 5K MagGo Slim is perfect for anyone who needs an ultra-portable, reliable power boost during the day. Here’s who will benefit the most from it:
- Commuters & City Travelers: Lightweight and compact enough to carry around without feeling weighed down.
- Students: Great for keeping your phone charged during lectures, study sessions, or long days on campus.
- Content Creators & Social Media Enthusiasts: If you’re vlogging, posting, or streaming, this power bank ensures your phone stays powered for content creation on the go.
- Daily Users: Anyone who needs a quick charge without the bulk, whether at work, on a walk, or during errands.
If you’re looking for something with more capacity for long trips or multiple charges, you might want to look at a 10,000mAh or higher model. But for day-to-day use, the Anker Nano 5K MagGo Slim is perfect.
The Verdict: A Winner for Everyday Life
At $85.90 the Anker Nano 5K MagGo Slim isn’t the cheapest option, but considering the performance, portability, and sleek design, it feels like a great value. It’s not intended for heavy-duty, off-grid adventures, but if you’re looking for a slim, magnetic power bank that can keep your phone charged through busy days without taking up space, it’s a solid investment.
