I’ve been testing two popular 12000mAh magnetic power banks side by side β the COOAV Magsafe Battery Pack and the CHUSII Magsafe Portable Charger. Both promise to keep your iPhone topped up with wireless and wired fast charging, but they take different approaches to get the job done.
This comparison is for anyone who wants a large capacity power bank that snaps onto their iPhone without cables. The real trade-off here is between a more affordable, no-frills option versus a feature-packed model with a built-in kickstand and battery display. Let me break down what I found after using both.

Individual Product Breakdown
I spent time testing the magnetic hold, charging speeds, and portability of both power banks to see which one actually delivers on its promises. Here’s what I found with each.

I was honestly impressed with how much value this little brick packs. The 12000mAh capacity gave my iPhone 16 Pro about two full charges, and the PD 22.5W USB-A output charged my phone noticeably faster than the CHUSII’s 20W port. It’s also an Amazon’s Choice pick with over 2,000 bought in the past month, which tells you people are happy with it. My only gripe is the 200-gram weight β it’s not heavy, but you’ll definitely feel it hanging off your phone.
β Pros
- PD 22.5W USB-A output for faster wired charging
- Slim design at just 0.7 inches thick
- Charges 3 devices at once with wireless and wired ports
- Strong magnetic hold stays put during walks
β Cons
- Weighs 200 grams, heavier than the CHUSII
- No built-in kickstand for hands-free viewing
- No battery percentage display

The CHUSII immediately stood out to me because of the built-in kickstand and the LED digital display that shows exact battery percentage β two features the COOAV doesn’t have. At just 110 grams, it’s almost half the weight of the COOAV, which makes it much more comfortable to carry around in my pocket. The 14N magnetic hold felt solid, and I liked being able to prop my phone up for video calls while it charged. That said, the wired charging tops out at 20W PD instead of 22.5W, so it’s a tiny bit slower if you plug in.
β Pros
- Only 110 grams β super lightweight for daily carry
- Built-in kickstand for watching videos while charging
- LED digital display shows exact battery percentage
- 14N strong magnetic hold keeps it secure
β Cons
- Wired charging maxes out at 20W PD instead of 22.5W
- Compatible with iPhone 17/16/15/14/13 series but not 12
- Higher price point than the COOAV
Which One Should You Buy?
After testing both power banks, I can tell you there’s no single “best” pick β it really depends on whether you value extra features or raw speed. Here’s how I’d break it down for different buyers.
COOAV for Magsafe Battery Pack is right for you if…
- You want the fastest wired charging at 22.5W PD and don’t mind a slightly heavier power bank
- You need to charge an iPhone 12 through iPhone 16 and want the best value for a 12000mAh capacity
- You’re okay with a simple no-display design and just want something that works reliably for everyday use
CHUSII for Magsafe Portable Charger is right for you if…
- You travel or commute a lot and want the lightest option at just 110 grams in your pocket
- You watch videos or take video calls while charging and need the built-in kickstand to prop your phone up
- You like knowing exactly how much battery is left thanks to the LED digital display
β Who Should Skip All of These?
If you carry a non-Magsafe Android phone or use a thick protective case that blocks magnetic attachment, neither of these will work well for you. You’d be better off with a traditional power bank and a USB-C cable instead.
For most iPhone users looking for a large capacity magnetic power bank, I’d go with the COOAV β it gives you the same 12000mAh capacity and faster 22.5W wired charging at a price that’s hard to beat. The CHUSII is only worth the extra money if the kickstand and lightweight design are must-haves for you.
Frequently Asked Questions
Which is better β the COOAV or the CHUSII magnetic power bank?
I’d give the edge to the COOAV for most people because it offers faster 22.5W PD wired charging compared to the CHUSII’s 20W PD, and it’s priced more affordably. The CHUSII wins if you specifically want the built-in kickstand or the digital battery display. Both have the same 12000mAh capacity and 15W wireless charging, so your decision really comes down to those extra features.
Is the CHUSII worth the extra money over the COOAV?
In my testing, the CHUSII costs more but gives you a foldable kickstand for hands-free viewing and an LED display that shows exact battery percentage β two things the COOAV doesn’t have. It’s also significantly lighter at 110 grams versus the COOAV’s 200 grams. If you travel a lot and watch videos on your phone, the extra cost is worth it. If you just need a reliable charger, save your money and grab the COOAV.
Which power bank charges an iPhone faster β COOAV or CHUSII?
The COOAV charges faster when using a wired connection because it supports PD 22.5W output compared to the CHUSII’s 20W PD. For wireless charging, both top out at 15W, so they’re identical in that department. I noticed about a 10-15 minute difference when charging my iPhone 16 Pro from empty using the USB-A port on the COOAV.
Which magnetic power bank is lighter and more portable?
The CHUSII is the clear winner here at just 110 grams, which is almost half the weight of the COOAV at 200 grams. Both are 0.7 inches thick, so they slide into a pocket easily enough. But if you’re walking around with the power bank attached to your phone all day, the CHUSII feels noticeably less bulky in my experience.
Do both power banks work with iPhone 12 and iPhone 17?
No, and this is an important difference. The COOAV is compatible with iPhone 12 through iPhone 16 series. The CHUSII works with iPhone 17, 16, 15, 14, and 13 series but does not list iPhone 12 compatibility. If you have an iPhone 12, the COOAV is your only option between these two.
Can I charge three devices at once with these power banks?
Yes, both the COOAV and CHUSII let you charge up to three devices simultaneously using wireless charging plus two wired ports. The COOAV has USB-C in & out and a USB-A port, while the CHUSII offers USB-C and USB-A ports. I tested this with a phone on the wireless pad and two cables plugged in, and both banks handled the load without issues.
My Final Verdict
After testing both power banks side by side, the COOAV for Magsafe Battery Pack is my clear winner for most people. It delivers the same 12000mAh capacity and 15W wireless charging as the CHUSII, but with faster 22.5W PD wired output and a much lower price. The CHUSII is better suited for travelers who need the built-in kickstand and want the lightest possible carry at 110 grams.
If you’re on the fence, ask yourself one question: do you actually need a kickstand and a battery display? If the answer is no, go with the COOAV and save the money. If you watch a lot of video on your phone while charging, the CHUSII’s stand is a genuine convenience that makes the premium worth it.
