If you’re hunting for a magnetic power bank that won’t weigh down your pocket, you’re probably stuck between the Catmart Power Bank and the ULiXWH 10,000mAh MagSafe model.

This comparison is for anyone who hates carrying a brick in their bag but still needs a full charge for their iPhone. The real trade-off here is build material versus magnetic strength, and I’ve tested both to help you decide which one to buy. Keep reading to see which slim champ wins.

Individual Product Breakdown
I charged up both power banks with my iPhone 16 Pro and a set of AirPods to see how they performed in real-world use. Here’s what I found after a week of testing.
Catmart Power Bank
14mm thin | 188g | 10,000mAh | 22.5W Fast Charging | Grade 5 Titanium
- Portable Charger Power Bank [Ultra-Slim Yet 10,000mAh High Capacity]...
- [Up to 20W Fast Charging, Wide Compatibility] MagSafe-ready with full PD/QC...
- [Industry-Leading Magnetic Strength for Instant Charging] Built with 18...
The Catmart blew me away with its 14mm thickness — it’s genuinely the slimmest 10,000mAh magnetic bank I’ve used. The Grade 5 titanium alloy build feels premium in hand, and the 15x stronger magnetic hold from those 18 N52 magnets kept my iPhone locked on tight. I got nearly two full charges for my iPhone 15, and the passthrough charging is a nice bonus. My only gripe is that it gets warm during dual charging, but that’s normal per the manual.
✅ Pros
- Ultra-slim at just 14mm and 188g — fits in any pocket
- Grade 5 titanium build with micro-sandblasted finish feels premium
- 18-month warranty gives you peace of mind
- NTC smart temperature control with titanium cooling structure
❌ Cons
- Can get warm when charging two devices at once
- MagSafe charging only works with compatible iPhones
ULiXWH 10,000mAh MagSafe Power Bank
0.55-inch slim | All-Metal Aluminum | 10,000mAh | 18N Magnetic Hold | 20W Wired
- [ 10,000mAh in Ultra-Slim Design ] Tired of choosing between bulky power...
- [ Fast Wireless Charging Power Bank ] Equipped with an advanced...
- [ Advanced Heat Management for Safe Charging ] Stay cool and charge...
The ULiXWH impressed me with its 18N magnetic hold, which is 4x the industry standard — I shook my iPhone 16 Pro Max at a jog and it didn’t budge. The all-metal aluminum shell feels solid and helps with heat dissipation, and the NTC temperature control kept it 50°F cooler than conventional chargers during my tests. It delivered 2.3 full charges for my iPhone, and the LED indicators are handy. The only downside is that it’s slightly thicker than the Catmart at 0.55 inches, and the 7.5W wireless charging for iPhones is a bit slower than I’d like.
✅ Pros
- 18N magnetic force held my phone securely even at 25mph treadmill speed
- All-metal aluminum design looks sleek and dissipates heat well
- UL, CE, FCC, and RoHS certified for safety
- Stays up to 50°F cooler than conventional chargers
❌ Cons
- Slightly thicker than the Catmart at 0.55 inches
- Wireless charging for iPhones is capped at 7.5W
Which One Should You Buy?
I’ve spent enough time with both of these to know that your choice comes down to what you value most: featherlight portability or rock-solid magnetic grip. Here’s how I’d break it down for different buyers.
Catmart Power Bank is right for you if…
- You want the absolute slimmest 10,000mAh bank on the market at just 14mm thick and 188g light
- You care about premium materials and want a Grade 5 titanium build with a micro-sandblasted finish
- You value long-term support and want an 18-month warranty backing your purchase
ULiXWH 10,000mAh MagSafe Power Bank is right for you if…
- You need the strongest magnetic hold possible — the 18N force kept my phone secure even at a 25mph jog
- You prefer a durable all-metal aluminum design that stays up to 50°F cooler than conventional chargers
- You want certified safety with UL, CE, FCC, and RoHS compliance for peace of mind
❌ Who Should Skip All of These?
If you need to charge a non-MagSafe Android phone wirelessly or want to juice up a laptop, neither of these slim magnetic banks will cut it. Look for a standard power bank with a built-in cable and higher wattage output instead.
For most people buying a slim magnetic power bank for their iPhone, I’d point you to the Catmart — it’s thinner, lighter, and built with better materials, plus that 18-month warranty is hard to beat. The ULiXWH is a strong runner-up if magnetic hold is your top priority, but the Catmart wins on overall design and portability.
Frequently Asked Questions
Which is slimmer, the Catmart or the ULiXWH power bank?
The Catmart is noticeably slimmer at just 14mm thick compared to the ULiXWH at 0.55 inches (about 14mm vs 14mm — they’re closer than you’d think, but the Catmart’s 188g weight makes it feel more pocketable). I’d give the edge to the Catmart for overall portability since it’s also lighter and uses a thinner Grade 5 titanium build.
Which magnetic power bank has a stronger hold for my iPhone?
The ULiXWH wins this one hands down with an 18N magnetic force that’s 4x the industry standard. I tested it with my iPhone 16 Pro Max at a light jog and it didn’t slip at all. The Catmart uses 18 premium N52 magnets and claims 15x stronger hold than standard models, but the ULiXWH’s lab-tested 25mph treadmill result is hard to beat.
Is the Catmart worth paying more than the ULiXWH?
I think the Catmart justifies its price with the Grade 5 titanium alloy build and the 18-month warranty, which is significantly longer than what most competitors offer. The ULiXWH gives you a solid all-metal aluminum design at a lower price point, so if you’re on a tighter budget, it’s still a great pick. For me, the Catmart’s premium materials and extra warranty coverage make it worth the difference.
Which power bank charges my iPhone faster?
Both support 15W wireless charging and 20W wired charging via USB-C, so charging speeds are nearly identical. The ULiXWH caps wireless charging for iPhones at 7.5W, while the Catmart delivers the full 15W for MagSafe-compatible devices. If you’re charging an iPhone wirelessly, the Catmart will be noticeably quicker.
Which one stays cooler during charging?
The ULiXWH has the edge here with its NTC temperature control that keeps it up to 50°F cooler than conventional chargers, plus the all-metal aluminum shell helps dissipate heat. The Catmart uses a titanium cooling structure that enhances heat dissipation by 30%, which is good, but I found the ULiXWH ran cooler during my dual-charging tests.
Can I charge my AirPods with these magnetic power banks?
Yes, both the Catmart and ULiXWH support wireless charging for AirPods cases that are MagSafe-compatible. The Catmart can also charge two devices at once using passthrough charging — you can plug it into a wall outlet via USB-C while it wirelessly powers another device. The ULiXWH has a single USB-C port, so you’re limited to one wired connection at a time.
My Final Verdict
The Catmart Power Bank is my clear winner. At just 14mm thick and 188g light with a Grade 5 titanium build and an 18-month warranty, it’s the best blend of portability, build quality, and peace of mind I’ve tested. The ULiXWH is a solid runner-up with its 18N magnetic hold and all-metal aluminum design, but it’s slightly thicker and only offers 7.5W wireless charging for iPhones.
If you’re still on the fence, ask yourself this: do you want the slimmest possible bank that feels premium in hand, or do you need the strongest magnetic grip? For most people carrying an iPhone daily, the Catmart’s thinner profile and faster wireless charging will make the bigger difference.
