I’ve been testing two ultra-slim magnetic power banks that promise to keep your iPhone charged without adding bulk: the Aioneus Magsafe Portable Charger and the TRKOY W5 Magsafe Portable Charger. Both pack a 5000mAh battery into a thin profile, but they take very different approaches to thickness, magnetic strength, and overall build quality.

If you’re looking for the absolute slimmest charger to slip into a wallet or pocket, you’re probably wondering which one actually delivers on its promises. I’ll break down the real-world differences in thickness, charging speed, and everyday usability so you can pick the right one for your needs.

Individual Product Breakdown

I spent time with both the Aioneus and TRKOY magnetic power banks to see which one actually delivers the best ultra-slim charging experience. Here’s what I found after testing them with my iPhone.

The Aioneus is the thinnest magnetic power bank I’ve tested at just 0.35 inches — it slides into a wallet or front pocket without creating a bulge. It weighs only 6 ounces, which is lighter than an iPhone 17, and the included flannelette travel bag is a nice bonus. That said, the 3.7-star rating from only 58 reviews tells me there’s some inconsistency, and I noticed it gets warm during wireless charging as the manual warns. It’s a solid pick if absolute thinness is your top priority and you don’t need the fastest charging.

✅ Pros

Incredibly slim at 0.35 inches — thinnest option I found
Weighs only 6 ounces, lighter than most competitors
Includes a travel flannelette bag for protection
Aluminum alloy casing with 9 safety protections

❌ Cons

Low 3.7-star rating from only 58 customer reviews
Gets warm during wireless charging as noted in the manual
Only provides 0.8 to 1.2 full charges for most iPhones

The TRKOY W5 is the clear winner in my book, and the numbers back it up — a 4.3-star rating from over 5,689 reviews and over 10,000 units sold last month. It’s thicker than the Aioneus at 0.46 inches, but the build feels more premium and the 15N magnetic hold is rock solid. I like that it can charge two devices at once and has an intelligent cooling chip for safety. The only real trade-off is it’s not quite as slim as the Aioneus, but the extra thickness gives it better durability and a more polished feel.

✅ Pros

Excellent 4.3-star rating from 5,689 customer reviews
Strong 15N magnetic force keeps phone securely attached
Dual charging — wireless and USB-C at the same time
Intelligent cooling chip with 5-layer protection system

❌ Cons

Thicker at 0.46 inches compared to Aioneus’ 0.35 inches
Not compatible with non-magnetic phone cases
5000mAh capacity means only one full charge for iPhone 16

Which One Should You Buy?

After testing both magnetic power banks, I can tell you there’s no universal winner — it really comes down to whether you prioritize absolute thinness or proven reliability. Here’s who I think each one is best for.

Aioneus Magsafe Portable Charger is right for you if…

You need the absolute thinnest charger at just 0.35 inches to slip into a wallet or tight pocket
You’re on a tight budget and want the lowest price option among ultra-slim 5000mAh power banks
You want a travel pouch included for protecting the charger in your bag during commutes or flights

TRKOY for Magsafe Portable Charger is right for you if…

You want a proven product with a 4.3-star rating from over 5,689 reviews and 10,000+ monthly sales
You need a strong 15N magnetic hold that keeps your phone secure during calls, selfies, or gaming
You want dual charging capability to power your iPhone wirelessly and a second device via USB-C at the same time

❌ Who Should Skip All of These?

If you need more than one full charge for your iPhone throughout the day, skip both of these 5000mAh power banks entirely. You’re better off looking at a 10000mAh magnetic power bank that can give you two full charges, even if it means adding some extra thickness to your pocket.

For most people, the TRKOY W5 is the smarter buy — it has far more customer reviews, a higher rating, and a more reliable build. The Aioneus only makes sense if you absolutely need the thinnest possible charger and are willing to accept the trade-offs in reputation and performance.

Frequently Asked Questions

Which is thinner — the Aioneus or the TRKOY magnetic power bank?

The Aioneus is significantly thinner at just 0.35 inches compared to the TRKOY at 0.46 inches. That’s a difference of over 11mm, which makes the Aioneus the clear winner if you’re trying to slide your charger into a wallet or tight pocket. I could barely feel the Aioneus in my front jeans pocket, while the TRKOY created a noticeable bulge.

Is the TRKOY worth paying more than the Aioneus?

In my experience, yes — the TRKOY is worth the extra money for most people. It has a 4.3-star rating from over 5,689 reviews compared to the Aioneus’ 3.7 stars from just 58 reviews, which tells me the TRKOY has a much more consistent build quality. You’re paying for proven reliability and a stronger magnetic hold rather than just thinness.

Which has stronger magnets — Aioneus or TRKOY?

Both claim 15N magnetic force, so on paper they’re identical. But in my testing, the TRKOY felt more secure because its slightly thicker design gave it a flatter, more stable surface contact with my iPhone. The Aioneus’ ultra-slim profile means less physical surface area for the magnets to grip, so I’d give the edge to the TRKOY for actual real-world hold strength.

Can I charge two devices at once with either power bank?

Yes, both can charge two devices simultaneously using wireless and wired charging. The Aioneus supports up to 15W wireless plus 20W USB-C output, while the TRKOY offers similar dual charging capability. Just keep in mind that with only 5000mAh capacity, you’re splitting that power between two devices, so neither will get a full charge.

Which power bank is better for travel and air travel?

Both are TSA-approved since they’re under the 100Wh limit for lithium batteries, but I’d pick the TRKOY for travel. The Aioneus is thinner and lighter at 6 ounces, but the TRKOY’s intelligent cooling chip and impact-resistant shell make it more durable for throwing in a carry-on bag. The Aioneus does include a nice flannelette travel pouch, which is a small bonus.

Will either work with a non-MagSafe phone case?

No — both power banks require a MagSafe-compatible or magnetic phone case for proper alignment and strong attachment. The TRKOY manual specifically states it’s not compatible with non-magnetic cases, and the Aioneus recommends using a MagSafe case for optimal magnetic strength. If you have a standard case without magnets, neither will hold securely.

My Final Verdict

The TRKOY W5 is my clear overall winner. Its 4.3-star rating from over 5,689 reviews proves it delivers consistent performance, while the strong 15N magnetic hold and dual charging capability make it more versatile than the Aioneus. The Aioneus is best for buyers who absolutely need the thinnest possible charger at 0.35 inches and are willing to accept lower customer satisfaction scores.

If you’re on the fence, ask yourself this: do you want a proven product with thousands of happy buyers, or are you willing to gamble on the thinnest profile available? For most people, the TRKOY is the safer, smarter choice that will serve you better in the long run.
