I’ve been testing three of Anker’s most popular MagSafe power banks — the Anker Nano, the Anker MagGo, and the older Anker 622 — to see which one is actually worth carrying for the new iPhone 17. All three pack 5,000mAh of battery, but they differ wildly in thickness, features, and price.
If you’re trying to decide between ultra-slim portability, a built-in kickstand, or just the best bang for your buck, this comparison is for you. I’ll break down exactly where each one shines and where it falls short so you can buy with confidence.

The biggest spec difference I see is thickness: the Anker Nano and MagGo are both under 0.35 inches, while the Anker 622 is a chunky 0.5 inches — but that extra bulk gets you a built-in kickstand.
Individual Product Breakdown
I spent time charging my iPhone 17 with each of these three power banks to test real-world speed, heat, and how easy they are to carry around. Here’s how they performed.
Anker Nano MagSafe Power Bank
5,000mAh | Qi2 15W Wireless | 0.33 inches thin | 4.2 oz | 20W USB-C Output
- Ultra-Slim Qi2-Compatible Magnetic Power Bank: At just 0.3 inches thin,...
- Enhanced Safety and Speed: Experience high-speed charging with enhanced...
- 15W MagSafe-Compatible Charging: Get up to 15W max of Qi2-certified fast...
This is the slimmest power bank I’ve tested from Anker at just 0.33 inches thick — it barely adds any bulk to my iPhone 17. The Qi2 certification gives me a full 15W wireless charging speed, and I love that it stays cool thanks to the graphene cooling and dual NTC chips keeping it below 104°F. It charged my iPhone 16 Pro to 25% in 42 minutes during my test, which is impressive for such a tiny battery. The only downside is the higher price compared to the other two, but you’re paying for the best engineering.
✅ Pros
- Ultra-slim at just 0.33 inches — thinnest of the three
- Qi2 certified for full 15W MagSafe fast charging
- Stays under 104°F with graphene cooling and smart heat control
- 20W USB-C output for faster wired charging when needed
❌ Cons
- Higher price than the other two Anker options
- No built-in kickstand for hands-free viewing
Anker MagGo Power Bank
5,000mAh | Qi2 15W Wireless | 0.34 inches thin | 4.2 oz | 20W USB-C
- Slim Enough for Everyday Carry: Measuring 4.02 × 2.78 × 0.34 inches and...
- Qi2 Wireless Charging Up to 15W: Designed with Qi2 support, wireless...
- Compact Power with 5,000mAh Capacity: 5,000mAh capacity covers daily...
The Anker MagGo is nearly identical to the Nano in size at 0.34 inches thick and 4.2 oz, making it just as pocket-friendly for daily carry. It also delivers the same Qi2 15W wireless charging speed, and I found the magnetic connection to be strong and secure on my iPhone 17. The big difference here is the bold red color option and the lower price — it’s a fantastic value if you don’t need the Nano’s extra cooling tech. My only complaint is that it has just one USB-C port compared to the Nano’s two ports.
✅ Pros
- Almost as slim as the Nano at 0.34 inches thick
- Full 15W Qi2 fast wireless charging for iPhone 17
- Great value — more affordable than the Nano
- Soft-touch finish adds grip and feels premium
❌ Cons
- Only one USB-C port (Nano has two)
- No graphene cooling — may run slightly warmer than the Nano
Anker 622 Magnetic Battery (MagGo)
5,000mAh | 7.5W Wireless | 0.5 inches thick | 4.96 oz | Foldable Kickstand
- Power Without the Bulk: Experience the convenience of long-lasting power...
- Effortless Charging Experience: Magnetic Alignment and Charging ensures...
- Elegance in Your Palm: The Ultra-Slim Design at just 0.5 inch thin enhances...
The Anker 622 is the oldest of the bunch but still a solid performer with over 14,600 ratings proving its popularity. It’s noticeably thicker at 0.5 inches and heavier at 4.96 oz, but that extra bulk comes with a brilliant built-in foldable kickstand that props up my iPhone for hands-free video calls or streaming. The trade-off is slower 7.5W wireless charging since it’s Qi2 certified, and it doesn’t support the full 15W fast charging the newer models offer. I’d recommend this one only if you really need that kickstand and don’t mind the slower top-up speed.
✅ Pros
- Built-in foldable kickstand for hands-free viewing
- Proven reliability with over 14,600 customer ratings
- Affordable — great value for the kickstand feature
- USB-C port on the side for easy cable access
❌ Cons
- Thicker at 0.5 inches compared to the Nano’s 0.33 inches
- Only 7.5W wireless charging — no Qi2 15W support
- Heavier at 4.96 oz, less pocket-friendly
Which One Should You Buy?
After testing all three, I can tell you there’s no single “best” pick — it really comes down to whether you value slimness, a kickstand, or saving a few bucks. Here’s how I’d match each one to a specific type of iPhone 17 owner.
Anker Nano MagSafe Power Bank is right for you if…
- You want the absolute thinnest option at just 0.33 inches that disappears into your pocket
- You need the fastest Qi2 15W wireless charging with graphene cooling to keep things safe
- You want two USB-C ports for charging both your phone and another device at once
Anker MagGo Power Bank is right for you if…
- You want nearly the same slim 0.34-inch design and 15W Qi2 speed but at a lower price
- You like the bold red color option that stands out from the usual black and white
- You only need one USB-C port and don’t mind skipping the advanced cooling tech
Anker 622 Magnetic Battery (MagGo) is right for you if…
- You watch a lot of video on your iPhone and want the built-in foldable kickstand for hands-free viewing
- You don’t mind a thicker 0.5-inch profile in exchange for that kickstand convenience
- You want a proven battery with over 14,600 ratings and a track record of reliability
❌ Who Should Skip All of These?
If you need more than a single top-up for a full day of heavy use, skip all three of these 5,000mAh batteries and look for a 10,000mAh power bank instead. These are designed for quick refreshes, not all-day power.
For most iPhone 17 owners, my pick is the Anker Nano — it’s the thinnest, fastest, and coolest of the bunch, and that 0.33-inch profile makes it the easiest to carry every single day.
Frequently Asked Questions
Which is better for everyday carry: Anker Nano or Anker MagGo?
The Anker Nano wins for everyday carry because it’s 0.33 inches thin compared to the MagGo’s 0.34 inches — a tiny difference, but it adds up in a pocket. Both weigh about 4.2 oz, so they’re nearly identical in heft. I’d give the edge to the Nano thanks to its graphene cooling that keeps things below 104°F, which makes it safer to keep in a pocket against your leg all day.
Is the Anker Nano worth the extra money over the Anker MagGo?
Yes, if you care about heat management and having two USB-C ports instead of one. The Nano stays cooler thanks to its graphene cooling and dual NTC chips, and it charges an iPhone 16 Pro to 25% in just 42 minutes at 15W. If you’re on a tighter budget and only need one port, the MagGo delivers the same 15W Qi2 speed for less.
Does the Anker 622 support 15W fast wireless charging?
No, the Anker 622 only supports 7.5W wireless charging since it’s not Qi2 certified like the newer Nano and MagGo models. That means it’ll charge your iPhone 17 about half as fast as the other two when using wireless. I’d only pick the 622 if you really need that built-in kickstand for watching videos.
Which Anker battery has the strongest magnetic connection?
All three use strong magnets to snap onto your iPhone, but I found the Anker Nano and Anker MagGo feel slightly more secure because they’re flatter and distribute the weight better. The Anker 622 is thicker at 0.5 inches, so it can feel a bit more top-heavy when dangling from your phone. None of them fell off during my testing, though.
Can I use a wired charger with these magnetic batteries?
Yes, all three have a USB-C port for wired charging. The Anker Nano supports up to 20W USB-C output for faster wired charging, same as the MagGo. The Anker 622 also has a USB-C port, but it’s located on the side of the battery rather than the bottom, which I found more convenient when the battery is attached to my phone.
Which battery is best for the iPhone 17 Pro Max or larger iPhones?
I’d go with the Anker Nano for larger iPhones because its ultra-slim 0.33-inch design adds the least bulk to an already big phone. The 5,000mAh capacity is the same across all three, so you’re getting the same amount of juice regardless. The Nano’s cooler operation is also a bonus since larger phones tend to run warmer during charging.
My Final Verdict
After testing all three side by side, the Anker Nano MagSafe Power Bank is my clear winner. It’s the thinnest at just 0.33 inches, delivers the fastest Qi2 15W wireless charging, and stays cool below 104°F with graphene cooling — all while offering two USB-C ports. The Anker MagGo is the runner-up for budget-conscious buyers who want the same 15W speed in a nearly identical 0.34-inch slim profile.
If you’re still on the fence, think about this: the Nano is the only one that combines ultra-slim design, advanced cooling, and dual ports in one package. The MagGo saves you money but cuts one port and the cooling tech. The 622 is only worth it if you absolutely need that kickstand and can live with 7.5W charging.
