I’ve been testing three ultra-slim 5000mAh magnetic power banks side-by-side: the TRKOY W5, the Aobbow W7, and the Magnpter AKD-YD52. All three promise to keep your iPhone topped up without the bulk of a traditional power bank, but they each have their own strengths and weaknesses.
Whether you’re a daily commuter, a frequent traveler, or just someone who hates carrying cables, this comparison will help you pick the right one. I’ll break down the real-world performance, build quality, and key features so you can make an informed choice.

Individual Product Breakdown
I spent a week carrying these three power banks everywhere to see how they actually hold up — here’s what I found with each one.
TRKOY for Magsafe Portable Charger W5
5000mAh | 15N magnetic force | 11.8mm thick | 4.3 stars (5,673 ratings)
- Precise Magnetic Alignment, Rock-Solid Hold: This magnetic portable charger...
- Slim & Portable — Power Without the Bulk: Bulky power banks just don't...
- 5000mAh Capacity, All-Day Peace of Mind: After extensive research and...
The TRKOY W5 impressed me the most out of the three. Its 15N magnetic force is noticeably stronger than the others — my iPhone 15 felt locked in place even when I was walking around taking calls. I also love that you can charge wirelessly and via the USB-C port at the same time, which is something neither the Aobbow nor the Magnpter can do. The only downside is it doesn’t have a battery percentage display, so you have to guess how much juice is left.
✅ Pros
- Strongest magnetic hold at 15N — stays put during calls and photos
- Dual charging: wireless and USB-C output at the same time
- Very slim at 11.8mm and lightweight at 120g
- Over 5,600 ratings with a solid 4.3-star average
❌ Cons
- No battery percentage display — you don’t know the exact charge left
- Only one color option (Graphite Gray)
Aobbow Magnetic Portable Charger W7
5000mAh | 10W wireless / 15W wired | LED display | 4.5 stars (56 ratings)

- Strong Magnetic Snap-On: Built-in magnets align securely with compatible...
- LED Digital Display: The clear LED screen shows the exact remaining battery...
The Aobbow W7 is the most polished option for travelers thanks to its clear LED digital display that shows the exact remaining battery percentage — a feature I really missed on the TRKOY. It snaps on securely and supports up to 10W wireless charging or 15W wired via USB-C. That said, it only has one port and can’t charge two devices at once, and its 4.5-star rating is based on just 56 reviews, which makes me a little less confident in long-term reliability.
✅ Pros
- LED digital display shows exact battery percentage remaining
- Ultra-slim and pocket-friendly design for travel
- Available in three colors: Space Gray, Rose Gold, and White
- 2.5-hour recharge time is fairly quick
❌ Cons
- Only one USB-C port — no simultaneous wired and wireless charging
- Relatively few customer reviews (56) compared to the TRKOY
Magnpter Magnetic Wireless Power Bank AKD-YD52

- 【Ultra Thin - Portable Design】 This 0.25 lb magnetic power bank has a...

The Magnpter AKD-YD52 is the thinnest of the bunch at just 0.3 inches, and it’s the only one that comes with a built-in 2-in-1 USB-C and Lightning cable, which is a genius touch. It also supports 20W wired PD charging, which is faster than both competitors for wired use. However, the magnetic hold isn’t as strong as the TRKOY, and its 4.1-star rating from only 57 reviews makes it feel like more of a gamble. It’s the most affordable option if you’re on a tight budget.
✅ Pros
- Thinnest at 0.3 inches and weighs just 0.25 lbs
- Built-in 2-in-1 USB-C & Lightning cable — no need to carry extra cords
- Faster 20W wired PD charging than the competition
- Aluminum alloy body for better heat dissipation
❌ Cons
- Magnetic hold isn’t as strong as the TRKOY
- Only 57 reviews and a 4.1-star rating — less proven track record
Which One Should You Buy?
I’ve spent enough time with these three to know that your choice really comes down to what matters most to you. Let me break down exactly who each one is for.
TRKOY W5 is right for you if…
- You want the strongest magnetic hold at 15N so your phone stays put during calls and photos
- You need to charge your phone wirelessly and a second device like AirPods via USB-C at the same time
- You prefer a proven product with over 5,600 ratings and 10K+ units bought in the past month
Aobbow W7 is right for you if…
- You want an LED digital display that shows the exact remaining battery percentage at a glance
- You travel frequently and want a lightweight, airline-approved power bank that slips into a pocket
- You like having color options — it comes in Space Gray, Rose Gold, and White
Magnpter AKD-YD52 is right for you if…
- You want the thinnest option at just 0.3 inches that barely adds any bulk to your phone
- You hate carrying extra cables and want a built-in 2-in-1 USB-C and Lightning cable
- You need faster 20W wired PD charging for a quick top-up
❌ Who Should Skip All of These?
If you need more than a single full charge for your phone, a 5000mAh battery won’t cut it — look for a 10000mAh or larger power bank instead. Also, if you have an Android phone without MagSafe compatibility, the magnetic attachment won’t work for you, so you’re better off with a standard power bank and a cable.
For most people, I recommend the TRKOY W5. It has the strongest magnetic hold, the most customer reviews, and the ability to charge two devices at once — which makes it the most versatile and reliable choice of the three.
Frequently Asked Questions
Which is better, the TRKOY or the Aobbow?
I’d pick the TRKOY W9 over the Aobbow W7 for most people. The TRKOY has a stronger 15N magnetic hold, dual charging capability (wireless plus USB-C at the same time), and over 5,600 ratings compared to the Aobbow’s 56. The Aobbow’s main advantage is the LED battery display, but the TRKOY is the more proven and versatile option.
Is the Magnpter worth the lower price compared to the TRKOY?
The Magnpter costs less and includes a built-in 2-in-1 USB-C and Lightning cable, which is a nice bonus. But you’re giving up the stronger 15N magnetic hold of the TRKOY and you only get 57 reviews versus 5,673. If saving money is your top priority, the Magnpter is fine, but the TRKOY is worth the extra for the better build and proven track record.
Which one is the thinnest and most portable?
The Magnpter AKD-YD52 is the thinnest at just 0.3 inches thick and weighs only 0.25 pounds. The TRKOY is 11.8mm thick and weighs 120g, while the Aobbow is also ultra-slim but doesn’t list its exact thickness. If absolute minimal bulk is your goal, the Magnpter wins.
Can any of these charge an iPhone and another device at the same time?
Only the TRKOY W5 can charge two devices simultaneously — it supports wireless MagSafe charging and has a separate USB-C output that works at the same time. The Aobbow and Magnpter only have one port each, so you can only charge one device at a time with those.
Which one has the fastest charging speed?
The Magnpter supports 20W wired PD charging, which is faster than the TRKOY’s 15W and the Aobbow’s 15W wired output. For wireless charging, the Aobbow tops out at 10W while both the TRKOY and Magnpter offer 15W wireless. If you’re plugging in, the Magnpter is fastest; if you’re going wireless, the TRKOY or Magnpter are better.
Do these work with iPhone 17 or the latest models?
All three claim compatibility with iPhone 17, 16, 15, 14, 13, and 12 series. The TRKOY even specifically mentions iPhone 17 Air and 17 Pro models in its listing. Just make sure you have a MagSafe-compatible case — none of these work with non-magnetic cases.
My Final Verdict
After all my testing, the TRKOY W5 is my clear winner. Its 15N magnetic hold is the strongest of the three, it’s the only one that can charge two devices at once, and its 4.3-star rating from over 5,600 reviews gives me real confidence in its quality. The Aobbow W7 is my runner-up — it’s a great pick if you absolutely need an LED battery display and don’t mind only charging one device at a time.
If you’re still on the fence, ask yourself this: do you want a proven, well-reviewed power bank that snaps on tight and charges two things at once? Get the TRKOY. Do you want the absolute thinnest design with a built-in cable to save money? Go with the Magnpter. Either way, you’re getting a solid 5000mAh battery that’ll give your iPhone a full charge.
