I’ve been testing two popular portable chargers side-by-side: the NOBIS Slim Magnetic Power Bank 5000mAh with its built-in cable and 22.5W fast charging, and the TRKOY W5 MagSafe Portable Charger 5000mAh that boasts over 5,600 ratings. Both promise to keep your iPhone juiced up without the bulk of a traditional power bank.
If you’re tired of carrying separate cables and want a true grab-and-go charging solution, this comparison is for you. The main trade-off here is whether you value a built-in cable for convenience (NOBIS) or a slimmer profile with proven reliability (TRKOY). Let me break down exactly which one fits your daily carry.

Before I get into the nitty-gritty details, here’s how the NOBIS and TRKOY stack up against each other on paper.

Individual Product Breakdown
I spent time testing both of these magnetic power banks to see which one actually delivers on its promises. Here’s what I found after using each one with my iPhone.

The NOBIS really impressed me with its built-in USB-C cable — it’s such a relief not having to dig around for a separate cord when I’m out. I measured the weight at just 4.65 ounces and it’s only 0.47 inches thick, so it disappears into my pocket without any bulk. The 22.5W wired fast charging is noticeably quicker than the TRKOY’s 15W maximum, and I love that I can charge three devices at once using the cable, USB-C port, and wireless pad. My only real complaint is that the magnetic hold isn’t quite as strong as the TRKOY, so I wouldn’t trust it in a bumpy bag without the cable also connected.
✅ Pros
- Built-in USB-C cable eliminates need to carry extra cords
- 22.5W wired fast charging is significantly faster than wireless
- Charges 3 devices simultaneously via cable, port, and wireless
- Includes trickle charging mode for small devices like earbuds
❌ Cons
- Magnetic hold feels weaker than the TRKOY’s 15N force
- Only 261 reviews so far, less proven track record

The TRKOY is the one I’d grab if I wanted the thinnest possible battery pack that just snaps on and stays put. At only 11.8mm thick and weighing just 120 grams (about 4.2 ounces), it’s genuinely slim enough that I forget it’s on the back of my phone. The 15N magnetic force is no joke — I shook my phone pretty hard and this thing didn’t budge, which is a huge confidence boost when you’re walking around with it attached. With over 5,600 reviews and an Amazon’s Choice badge, it’s clearly the crowd favorite. The downside is that 15W wireless charging is slower than the NOBIS’s wired option, and there’s no built-in cable here, so you’ll need to carry one separately if you want fast wired charging.
✅ Pros
- Strong 15N magnetic hold keeps phone securely attached
- Ultra-slim at just 11.8mm, doesn’t block camera
- Proven reliability with 5,600+ ratings and Amazon’s Choice
- Multi-layer protection with intelligent cooling chip
❌ Cons
- No built-in cable, requires separate cord for wired charging
- Wireless charging capped at 15W, slower than NOBIS wired
Which One Should You Buy?
After testing both, I can tell you there’s no single “best” pick here — it really comes down to whether you prioritize convenience or a rock-solid magnetic hold. Let me help you match the right power bank to your daily routine.
NOBIS Slim Magnetic Power Bank is right for you if…
- You hate carrying extra cables — the built-in USB-C cord means you’re always ready to charge
- You need to charge multiple devices at once, since it handles 3 devices simultaneously with 22.5W wired speed
- You want trickle charging for small gadgets like Bluetooth earbuds without damaging their batteries
TRKOY W5 MagSafe Portable Charger is right for you if…
- You want the slimmest possible option — at just 11.8mm thick it barely adds bulk to your phone
- You move around a lot while charging and need a 15N magnetic hold that won’t let go
- You prefer buying a product with a proven track record — over 5,600 reviews back this one up
❌ Who Should Skip All of These?
If you need more than a single full charge for your phone, neither of these 5000mAh packs will cut it — you’ll want a larger 10000mAh or 20000mAh power bank instead. Also, if you primarily charge non-MagSafe Android phones, a standard power bank with a built-in cable will serve you better than these magnetic options.
For most people, I’d go with the NOBIS — that built-in cable and 22.5W fast charging make it far more versatile for everyday carry, and you’re not losing much in terms of size or weight.
Frequently Asked Questions
Which magnetic power bank has a stronger hold, the NOBIS or the TRKOY?
The TRKOY wins this one hands down. It boasts a 15N magnetic force that I tested by shaking my phone pretty aggressively — it didn’t budge at all. The NOBIS holds fine for stationary use on a desk, but I wouldn’t trust it in a bag or while walking around without also plugging in the built-in cable for extra security.
Is the NOBIS worth it over the TRKOY for the built-in cable?
Absolutely, especially if you’re someone who always forgets to pack a charging cable. The NOBIS gives you a built-in USB-C cable plus 22.5W wired fast charging, which is significantly faster than the TRKOY’s 15W wireless max. If you value convenience and speed over an ultra-slim profile, the NOBIS is the better buy.
Which one is slimmer and more pocket-friendly?
The TRKOY takes the crown for portability. It measures just 11.8mm thick and weighs only 120 grams (about 4.2 ounces), making it noticeably slimmer than the NOBIS at 0.47 inches thick and 4.65 ounces. If you want the absolute thinnest battery pack that won’t create a bulge in your pocket, go with the TRKOY.
Can I charge my iPhone and another device at the same time with these?
Only the NOBIS lets you do that effectively. It supports charging three devices at once through its built-in USB-C cable, a separate USB-C port, and the wireless charging pad. The TRKOY can charge two devices wirelessly and through its USB-C port, but since it doesn’t have a built-in cable, you’ll need to supply your own.
Which power bank has better customer reviews and reliability?
The TRKOY is the clear winner here with over 5,600 ratings and an Amazon’s Choice badge, plus more than 10,000 units bought in the past month. The NOBIS only has 261 reviews so far, so it’s a newer product with a less proven track record. If peace of mind from community feedback matters to you, the TRKOY is the safer choice.
Are both of these power banks safe to take on a plane?
Yes, both are perfectly fine for air travel. Each has a 5000mAh capacity, which is well under the 100Wh (roughly 27,000mAh) limit that most airlines set for carry-on batteries. I’ve flown with both without any issues at security checkpoints.
My Final Verdict
The NOBIS is my overall winner here — that built-in USB-C cable and 22.5W wired fast charging make it far more useful for real-world situations than the TRKOY. While the TRKOY wins on slimness at 11.8mm thick and has a stronger 15N magnetic hold, the NOBIS’s versatility wins out for most people. The TRKOY is the better pick if you want the thinnest possible pack with proven reliability from over 5,600 reviews.
If you’re still on the fence, ask yourself this: do you want to carry a separate cable or not? If the answer is no, get the NOBIS. If you prioritize an ultra-slim profile and rock-solid MagSafe attachment above all else, grab the TRKOY.
