I’ve been testing two 10,000mAh power banks that look similar on paper: the Aaoyun Portable Charger and the Anker Nano Power Bank. Both have built-in USB-C cables and fast charging, but the Aaoyun costs a fraction of what Anker asks while packing a metal case.
This is for anyone who wants a reliable backup battery but doesn’t want to overspend. The trade-off is simple: do you need laptop charging speed or are you fine with phone-only power? Let me break it down.
🏆 Quick Picks — My Top Recommendations
Best Overall: Aaoyun Portable Charger
Best value at a much lower price, with a metal case that’s 0.6 inches thin and a lab-verified 10,000mAh — Check Price →
Runner-Up: Anker Nano Power Bank
30W bi-directional charging that can top up a MacBook, and recharges itself to 50% in 45 minutes — Check Price →
Here’s how the Aaoyun and Anker Nano stack up head-to-head on the specs that matter most to budget buyers like me.

The biggest difference I see is the Aaoyun’s 22.5W PD charging versus the Anker’s 30W bi-directional — that extra speed on the Anker matters if you need to charge a laptop, but for phones only, the Aaoyun is plenty fast.
Individual Product Breakdown
I tested both power banks by charging my iPhone 15 Pro and a Samsung S24, timing how fast each one topped up the phones and checking how well the built-in cables held up. Here’s what I found.

I was honestly surprised by the Aaoyun for the price. The CNC-machined aluminum case feels premium in hand and dissipates heat 40% faster than plastic rivals, which matters when you’re pulling 22.5W — it charged my iPhone 15 to 63% in 30 minutes, just as claimed. The built-in USB-C cable is sturdy, and at 0.6 inches thick it’s thinner than my iPhone 16 Pro case. My only gripe is the 22.5W output won’t charge a laptop, but for phones and tablets this thing is a steal.
✅ Pros
- Metal case is 2X more durable than plastic competitors
- 22.5W PD charges iPhone 16/17 to 63% in 30 minutes
- Only 0.6 inches thick and weighs 6.8 oz
- Comes with a 3-year warranty
❌ Cons
- 22.5W not enough for laptop charging
- Only 285 reviews so far, less proven than Anker

The Anker Nano is the smart pick if you need laptop charging. Its 30W bi-directional output means I could top up my MacBook Air in a pinch, and it recharges itself to 50% in just 45 minutes — way faster than the Aaoyun. The built-in USB-C cable is convenient, and with 9,376 reviews it’s a proven product. The trade-off is it costs more, plus the plastic shell feels cheaper than the Aaoyun’s aluminum body, though 80% of that plastic is recycled material.
✅ Pros
- 30W output can charge laptops and phones
- Self-recharges to 50% in 45 minutes
- Over 9,300 reviews with 4.5 stars
- Made with 80% recycled plastic
❌ Cons
- Costs more than the Aaoyun
- Plastic body feels less premium than metal
- Thicker at 1.02 inches vs Aaoyun’s 0.6 inches
Which One Should You Buy?
I’ve spent enough time with both of these power banks to know there isn’t one universal winner — it really comes down to what devices you carry and how much you want to spend. Let me match you to the right one.
Aaoyun Portable Charger Power Bank is right for you if…
- You want the most bang for your buck — this is the cheaper option with a metal case and 22.5W PD fast charging.
- You carry your power bank in a pocket or small bag — at 0.6 inches thick and 6.8 ounces, it’s noticeably slimmer and lighter than the Anker.
- You only need to charge phones, tablets, and earbuds — the 22.5W output is plenty fast for iPhones and Samsung devices.
Anker Nano Power Bank is right for you if…
- You need to charge a laptop or MacBook — the 30W output is enough to top up a MacBook Air in a pinch.
- You want the fastest self-recharge — the Anker hits 50% in just 45 minutes, which is noticeably quicker than the Aaoyun.
- You prefer a brand with a massive track record — over 9,300 reviews give you confidence in long-term reliability.
❌ Who Should Skip All of These?
If you need to charge a full-size laptop multiple times or run a mini fridge at a campsite, neither of these 10,000mAh packs will cut it — look for a power station with at least 20,000mAh and 60W+ output instead.
For the vast majority of phone and tablet users on a budget, my pick is the Aaoyun. It gives you a tougher metal build, a slimmer profile, and reliable 22.5W charging at a price that’s hard to beat. Spend the extra cash on a good case instead.
Frequently Asked Questions
Which power bank is better for budget buyers — Aaoyun or Anker Nano?
For pure budget buyers, the Aaoyun is the clear winner. It costs less while still delivering 22.5W PD fast charging, a metal case, and a lab-verified 10,000mAh capacity. I’d only recommend the Anker Nano over it if you specifically need the 30W output for laptop charging — otherwise, save your money and get the Aaoyun.
Is the Anker Nano worth the extra money over the Aaoyun?
In my testing, only if you need to charge a MacBook or want the fastest self-recharge. The Anker’s 30W bi-directional charging tops itself up to 50% in 45 minutes, which is handy, and it can power a laptop. But if you’re only charging phones and tablets, I don’t think the extra cost is worth it — the Aaoyun’s 22.5W is plenty fast for iPhones and Samsung devices.
Which power bank is slimmer and more portable?
The Aaoyun wins here by a noticeable margin. It’s only 0.6 inches thick and weighs 6.8 ounces, while the Anker Nano is 1.02 inches thick and 7.58 ounces. I could slip the Aaoyun into a jeans pocket easily — the Anker is thick enough that I’d only carry it in a bag.
Which one has a better build quality — metal or plastic?
The Aaoyun’s CNC-machined aluminum alloy case feels significantly more premium than the Anker’s plastic shell. Aaoyun claims the metal dissipates heat 40% faster than plastic, and I did notice it stayed cooler during fast charging. That said, the Anker uses 80% recycled plastic in its casing, so it’s the more environmentally friendly option if that matters to you.
Can either power bank charge a laptop?
Only the Anker Nano can handle a laptop. Its 30W max output is enough to slowly top up a MacBook Air or similar ultrabook. The Aaoyun maxes out at 22.5W, which won’t keep a laptop running under load — stick to phones, tablets, and earbuds with that one.
Which power bank has more customer reviews and is more trusted?
The Anker Nano is far more proven, with over 9,376 reviews and a 4.5-star rating. The Aaoyun only has 285 reviews at 4.6 stars, though it does carry an Amazon’s Choice badge. If you’re risk-averse and want a product thousands of people have already tested, go with the Anker. If you’re willing to save money on a newer product with a 3-year warranty, the Aaoyun is a solid bet.
My Final Verdict
The Aaoyun Portable Charger is my clear winner for budget buyers. It gives you a metal case, 22.5W PD fast charging, and a slim 0.6-inch profile at a price that undercuts the Anker by a wide margin — and it still charges an iPhone 15 to 63% in 30 minutes. The Anker Nano is a solid runner-up if you need 30W laptop charging or want the reassurance of 9,300+ reviews, but for most phone and tablet users, the Aaoyun is the smarter buy.
If you’re still on the fence, ask yourself one question: do you need to charge a laptop? If the answer is no, save your money and grab the Aaoyun. Its aluminum build feels better in hand, it’s thinner, and you get a 3-year warranty — that’s a deal I can’t argue with.
