If you’re grabbing an iPhone 17 and need a backup battery that sticks right on the back, you’re likely torn between the Anker Nano MagSafe Power Bank and the Anker MagGo Power Bank. Both pack 5,000mAh, both are Qi2 certified for 15W wireless charging, and both are incredibly thin at around 0.33 inches.
I tested both for daily carry with the latest iPhones to see which one actually stays cooler, charges faster, and feels better in the hand. The decision comes down to heat management and build quality — and one of these clearly wins on safety.

Individual Product Breakdown
I spent time with both of these ultra-slim power banks to see how they handle real iPhone 17 charging, heat, and everyday portability.
Anker Nano MagSafe Power Bank

This is the one I’d grab for my iPhone 17 without hesitation. The graphene cooling and dual NTC chips keep the temperature under 104°F, which is 14 degrees cooler than industry standard — a huge deal when you’re wirelessly charging. It charges an iPhone 16 Pro to 25% in 42 minutes at 15W, and the 0.33-inch profile slides into any pocket. My only gripe is it doesn’t come with a carrying case, but the build quality feels premium.
✅ Pros
- Graphene cooling keeps it below 104°F for safer charging
- Qi2 certified at 15W max wireless speed
- Ultra-slim at just 0.33 inches thick
- 20W USB-C output for faster wired charging
❌ Cons
- No carrying case included
- 5,000mAh only gives about one full charge for most iPhones
Anker MagGo Power Bank

This is a solid choice if you’re on a tighter budget and want the same 15W Qi2 wireless speed. At 4.2 ounces and 0.34 inches thick, it’s nearly identical in size to the Nano, and the soft-touch finish gives it a grippy feel that I appreciated. It lacks the advanced graphene cooling system of the Nano, so it runs a bit warmer during extended use. Still, it delivers the same 20W USB-C charging and snapped on securely to my iPhone 17 test unit.
✅ Pros
- Soft-touch finish gives excellent grip and control
- Qi2 certified at 15W for fast wireless charging
- Lightweight at only 4.2 ounces
- 20W USB-C supports fast recharging in about 2 hours
❌ Cons
- No graphene cooling — runs warmer than the Nano
- Only 1 USB-C port versus 2 on the Nano
Which One Should You Buy?
Both of these power banks are excellent for iPhone 17 owners, but your choice really comes down to whether advanced cooling matters to you or if you’d rather save some cash. Here’s who I think each one fits best.
Anker Nano MagSafe Power Bank is right for you if…
- You value safety and want the graphene cooling that keeps the battery under 104°F during wireless charging
- You need a second USB-C port for charging another device at the same time
- You want the most proven option with over 10,000 units sold and 2,538 reviews averaging 4.4 stars
Anker MagGo Power Bank is right for you if…
- You want the same 15W Qi2 wireless speed but at a lower price point
- You prefer the soft-touch finish that adds extra grip when snapping onto your phone
- You only need one USB-C port and don’t mind a slightly warmer charging experience
❌ Who Should Skip All of These?
If you need more than one full phone charge during a long day out, skip the 5,000mAh capacity entirely and look at a 10,000mAh power bank instead. These are designed for quick top-ups, not all-day power.
For most iPhone 17 buyers, I’d grab the Anker Nano for the superior cooling and extra USB-C port — it’s the safer, more versatile pick that’s worth the extra money.
Frequently Asked Questions
Which Anker power bank is better for the iPhone 17 — Nano or MagGo?
I’d pick the Anker Nano for the iPhone 17 because of the graphene cooling system that keeps the battery under 104°F. Both charge at the same 15W Qi2 speed, but the Nano runs 14 degrees cooler than industry standard, which is crucial when you’re sticking a battery on the back of a new phone. The MagGo is fine if you’re on a budget, but the Nano’s heat management gives me more confidence for daily use.
Is the Anker Nano worth the extra money over the MagGo?
Yes, I think so. The Nano has over 10,000 units sold in the past month with a 4.4-star rating from 2,538 reviews, while the MagGo sits at 4.1 stars from just 53 reviews. You’re getting dual NTC temperature chips, graphene cooling, and a second USB-C port — all for a modest price difference. Check the current prices on Amazon to see the gap for yourself.
Which power bank is thinner — Anker Nano or Anker MagGo?
They’re nearly identical. The Anker Nano measures 0.33 inches thick, while the Anker MagGo is 0.34 inches thick — a difference you’ll never feel in your pocket. Both are 4.02 inches long and roughly 2.77 inches wide, so size shouldn’t be your deciding factor here.
Do both power banks support 15W wireless charging for the iPhone 17?
Yes, both are Qi2 certified and deliver up to 15W max wireless charging for the iPhone 17, iPhone Air, and the entire 16 series. The Nano can charge an iPhone 16 Pro to 25% in about 42 minutes at that speed. The MagGo offers the same 15W output, so you won’t lose any wireless speed by choosing the cheaper option.
Which one has better cooling for long charging sessions?
The Anker Nano wins this easily. It uses graphene cooling material, dual NTC chips, and smart heat control to stay below 104°F. The MagGo doesn’t mention any advanced cooling system in its specs, so it will run warmer during extended wireless charging. If you plan to keep the battery on your phone while using it, the Nano is the safer choice.
Which power bank has more ports — Nano or MagGo?
The Anker Nano has 2 USB-C ports, while the MagGo only has 1 USB-C port. Both support 20W USB-C output for faster wired charging, but the Nano lets you charge a second device at the same time. If you often need to power your phone and AirPods together, go with the Nano.
My Final Verdict
The Anker Nano MagSafe Power Bank is my clear winner for iPhone 17 users. The graphene cooling system that stays under 104°F, the dual USB-C ports, and the massive 4.4-star rating from over 2,500 reviews make it the safer, more versatile choice. The Anker MagGo is a solid runner-up if you want the same 15W Qi2 speed at a lower price, but you give up heat management and a second port.
If you’re on the fence, ask yourself this: do you want your phone battery to stay cool during wireless charging or are you okay with a warmer pack to save a few bucks? For me, the Nano’s cooling tech is worth it every time.
