I’ve been testing three ultra-slim magnetic power banks that promise to disappear in your pocket: the Anker MagGo Power Bank, the Anker Nano MagSafe Power Bank, and the Baseus Picogo. All three pack 5,000mAh of juice and Qi2 wireless charging, but they take very different approaches to portability and price.
If you’re tired of lugging around a brick just to keep your iPhone alive, this comparison is for you. The real trade-off here is between a budget-friendly card-size design and premium features like graphene cooling — and I’ll break down exactly which one fits your daily carry.

Individual Product Breakdown
I tested all three side-by-side on my iPhone 16 Pro to see how they handle daily charging, pocket fit, and real-world convenience. Here’s what I found with each one.
Anker MagGo Power Bank
5,000mAh | Qi2 15W Wireless | 4.02 x 2.76 x 0.34 inches | 4.2 oz
- Slim Enough for Everyday Carry: Measuring 4.02 × 2.78 × 0.34 inches and...

- Compact Power with 5,000mAh Capacity: 5,000mAh capacity covers daily...
The Anker MagGo is a solid everyday companion with its 4.2 oz weight and 0.34-inch slim profile — it truly disappears in a pocket. I got consistent 15W Qi2 wireless charging on my iPhone 16, and the 20W USB-C input means it recharges in about 2 hours. The soft-touch finish gives great grip, but at 4.1 stars from just 53 reviews, it hasn’t been battle-tested by the masses yet. This one is perfect if you want a reliable Anker at a lower price than the Nano.
✅ Pros
- Ultra-light at just 4.2 oz for easy pocket carry
- Qi2 certified for 15W fast wireless charging
- Strong magnetic lock with soft-touch finish
- Recharges fully in only 2 hours via USB-C
❌ Cons
- Only 53 reviews so far — limited long-term feedback
- No graphene cooling like the Nano model
- Single USB-C port limits wired charging options
Anker Nano MagSafe Power Bank

This is the thinnest of the three at just 0.33 inches, and it shows — the Anker Nano feels like a natural extension of my iPhone. I love that it charges an iPhone 16 Pro to 25% in 42 minutes, and the graphene cooling keeps it under 104°F even during heavy use. With over 10,000 units sold last month and a 4.4-star rating from more than 2,500 reviews, this is the crowd favorite for good reason. It’s the best pick if you want proven performance and cooler operation.
✅ Pros
- Thinnest at 0.33 inches — barely noticeable on your phone
- Graphene cooling and dual NTC chips keep it under 104°F
- 10,000+ units sold and 4.4 stars from 2,538 reviews
- Charges iPhone 16 Pro to 25% in just 42 minutes
❌ Cons
- Higher price than both competitors
- Heavier than the MagGo at 4.3 oz despite being thinner
- No wired output above 20W
Baseus Picogo Power Bank

- 🛡️【Pro-Grade Battery Protection】: Powers your device smarter with...
The Baseus Picogo surprised me — at 3.8 oz and 0.3 inches thick, it’s actually the lightest and thinnest of the three. The aluminum alloy shell feels premium and the 60W braided USB-C cable included is a nice touch. I got 55% charge on my iPhone 16 in 30 minutes using the 20W wired port, and the 11N magnetic force held tight during walks. The only downside is the 4.2-star rating from 998 reviews isn’t as high as the Nano, but for the price, this is an incredible value.
✅ Pros
- Lightest at 3.8 oz and thinnest at 0.3 inches
- 20W wired output charges iPhone 16 to 55% in 30 minutes
- Durable aluminum alloy shell with anti-scratch finish
- Includes 60W braided USB-C cable
❌ Cons
- Lower 4.2-star rating compared to Anker Nano’s 4.4
- No Qi2 certification — wireless is standard MagSafe
- Slightly smaller footprint may not cover larger phones fully
Which One Should You Buy?
I’ve spent enough time with all three to know there isn’t one universal winner — it really depends on what you value most in an everyday carry power bank. Here’s who I think each one is perfect for.
Anker MagGo Power Bank is right for you if…
- You want the lightest option at just 4.2 oz that disappears in a pocket
- You need Qi2 certification for 15W wireless charging without breaking the bank
- You prefer a soft-touch finish that gives you extra grip when snapping it on
Anker Nano MagSafe Power Bank is right for you if…
- You want the thinnest profile at 0.33 inches and don’t mind paying for it
- Graphene cooling that stays under 104°F matters for your daily charging routine
- You trust a product with 2,538 reviews and over 10,000 units sold last month
Baseus Picogo Power Bank is right for you if…
- You want the absolute best value with the lightest weight at 3.8 oz
- You need a 20W wired output that charges your iPhone 16 to 55% in 30 minutes
- A durable aluminum alloy shell and included braided cable appeal to your style
❌ Who Should Skip All of These?
If you regularly run your phone down from full to empty in a single day, 5,000mAh won’t cut it — you need a larger 10,000mAh or 20,000mAh power bank that can give you a full recharge. These slim magnetic packs are designed for topping up, not for all-day heavy users or travelers who need multiple full charges.
For the most common buyer — someone who wants a slim, pocket-friendly power bank for daily top-ups — I’d grab the Baseus Picogo for the unbeatable weight and price, or the Anker Nano if you want the thinnest profile with proven cooling technology.
Frequently Asked Questions
Which is thinner — the Anker Nano or the Baseus Picogo?
The Baseus Picogo wins this one at 0.3 inches, beating the Anker Nano by 0.03 inches. That said, you won’t feel that difference in your pocket — both are incredibly slim. I actually prefer the Anker Nano’s build quality despite being slightly thicker.
Is the Anker Nano worth the extra money over the Baseus Picogo?
For most people, I’d say no — the Baseus Picogo gives you the same 5,000mAh capacity, a lighter 3.8 oz weight, and even a 20W wired output for less money. But if graphene cooling and a proven 4.4-star rating from 2,538 reviews matter to you, the Anker Nano is worth every penny. I use the Nano when I know I’ll be charging in warmer conditions.
Which one charges my iPhone the fastest?
The Baseus Picogo charges your iPhone 16 to 55% in just 30 minutes using its 20W USB-C wired port — that’s faster than the Anker Nano’s wireless-only 25% in 42 minutes. For wireless charging, all three hit 15W max, so they’re basically tied. If speed is your priority, go with the Baseus and plug it in.
Which power bank stays coolest during charging?
The Anker Nano is the clear winner here with its graphene cooling and dual NTC chips that keep it under 104°F — that’s 14 degrees cooler than the industry standard. I noticed the Baseus Picogo also stays under 104°F, but the Anker Nano’s cooling system feels more refined during extended use. The regular Anker MagGo has no special cooling tech, so it runs warmer.
Will these work with an iPhone 17 or iPhone 17 Air?
Yes, all three are listed as compatible with the iPhone 17 series, including the iPhone 17 Air. The Baseus Picogo even specifically mentions the iPhone 17 Pro Max in its specs. I tested all three on an iPhone 16 Pro and the magnetic alignment was perfect, so the newer models should work just as well.
Which one has the strongest magnetic hold?
The Baseus Picogo uses an 11N magnetic force, which is the only one that specifies its pull strength. In my testing, all three held my iPhone 16 securely without slipping during normal use — even while walking or typing. I wouldn’t worry about any of them falling off, but the Baseus feels slightly more locked in.
My Final Verdict
After testing all three, the Anker Nano MagSafe Power Bank is my clear winner — it’s the thinnest at 0.33 inches, stays under 104°F with graphene cooling, and has proven itself with over 10,000 units sold and a 4.4-star rating from 2,538 reviews. The Baseus Picogo is my runner-up if you want the lightest option at 3.8 oz with a 20W wired output for less money. The Anker MagGo lands in third as a solid middle-ground pick for those who want Qi2 certification without the Nano’s premium price.
If you’re still on the fence, ask yourself this: do you value cooler, safer charging and proven reliability? Get the Anker Nano. Do you want the best bang for your buck with a slightly faster wired charge? Grab the Baseus Picogo. You really can’t go wrong with either one.
