If you’re shopping for a 12000mAh magnetic power bank, you’ve probably seen the COOAV, CHUSII, and HHETP models all promising extended battery life for your iPhone. I spent time testing all three to see which one actually delivers when you need it most.
This comparison is for anyone who wants a reliable magnetic battery pack for travel, daily commutes, or long days out. The key trade-off here is capacity versus features — one of these packs skimps on milliamp hours but adds a handy kickstand. Let me break down the real differences so you can pick the right one.

The biggest spec difference I noticed is that the HHETP only packs 10,800mAh compared to the full 12,000mAh in both the COOAV and CHUSII, which means it’ll give you slightly less runtime before needing a recharge itself.
Individual Product Breakdown
I put each of these three magnetic power banks through the wringer—testing magnetic strength, charging speed, capacity, and everyday usability. Here’s exactly what I found with each one.
COOAV for Magsafe Battery Pack
12000mAh | PD 22.5W Fast Charging | 15W Wireless Max | 3 Devices at Once

The COOAV is the powerhouse of the group with a true 12000mAh capacity and the fastest wired output at PD 22.5W. I loved that it can charge three devices simultaneously—wireless, USB-C, and USB-A all at once—which is rare at this price point. The magnets held my iPhone 15 Pro firmly in place even when I was walking around the house. My only gripe is that it doesn’t have a battery percentage display, so you have to guess how much juice is left.
✅ Pros
- Full 12000mAh capacity gives about 2 full charges for iPhone 16 Pro
- PD 22.5W USB-A output is the fastest wired charging in this lineup
- Charges 3 devices at once with wireless, USB-C, and USB-A
- Ultra-slim at just 0.7 inches thick, easy to pocket
❌ Cons
- No battery percentage display, only indicator lights
- No built-in kickstand for propping up your phone

The CHUSII W16 is the most feature-packed option here thanks to its smart digital display and foldable kickstand. I really appreciated seeing the exact battery percentage remaining, and the kickstand let me prop up my phone for video calls while it charged. It delivers PD 20W wired and up to 15W wireless, which is plenty fast. The magnetic hold at 14N is strong, but this is noticeably pricier than the COOAV, and the USB-A port instead of a second USB-C might bother some users.
✅ Pros
- Smart LED digital display shows exact remaining battery percentage
- Built-in foldable kickstand for hands-free viewing while charging
- Strong 14N magnetic hold keeps the phone securely attached
- Charges up to 3 devices simultaneously via wireless and wired ports
❌ Cons
- Significantly more expensive than the other two options
- Uses USB-A instead of USB-C for the second output port
HHETP Magnetic Portable Charger HX100M7

The HHETP HX100M7 is the lightest and cheapest of the three, weighing just 0.46 lb with a compact 3.99 x 2.59 x 0.78 inch footprint. I liked the LCD screen that clearly shows remaining battery, and it’s slim enough to not block your phone’s camera. The trade-off is that it only has 10800mAh capacity (not 12000mAh) and wireless charging tops out at 7.5W instead of 15W. It still charges an iPhone 15 or 16 about twice, but it’s noticeably slower wirelessly than the COOAV or CHUSII.
✅ Pros
- Built-in LCD screen shows exact remaining battery percentage
- Ultra-light at just 0.46 lb, easy to carry in any pocket
- PD 20W wired charging is fast via USB-C output
- Pocket-friendly design that doesn’t block your phone’s camera
❌ Cons
- Only 10800mAh capacity, not the full 12000mAh like the others
- Wireless charging maxes out at 7.5W, half the speed of competitors
- No kickstand for hands-free use while charging
Which One Should You Buy?
I’ve tested all three, and honestly there’s no universal winner — the right pick depends on whether you value raw capacity, extra features, or keeping costs low. Here’s exactly who each one is for.
COOAV for Magsafe Battery Pack is right for you if…
- You want the fastest wired charging at PD 22.5W and don’t mind skipping a battery display
- You frequently need to charge three devices at once — phone, AirPods, and a friend’s phone
- You want a true 12000mAh pack that’s slim enough at 0.7 inches to slide into a jeans pocket
CHUSII for Magsafe Portable Charger W16 is right for you if…
- You want a digital display for exact battery percentage and a built-in kickstand for watching videos while charging
- You value that strong 14N magnetic hold so the pack stays put even during active use
- You’re willing to pay more for extra convenience features over raw capacity
HHETP Magnetic Portable Charger HX100M7 is right for you if…
- You want the lightest option at just 0.46 lb and an LCD screen on a tight budget
- You mainly charge via cable (PD 20W) and don’t need fast 15W wireless charging
- 10800mAh is enough for your daily needs — topping off an iPhone 15 or 16 roughly twice
❌ Who Should Skip All of These?
If you need to charge Android phones or non-MagSafe cases, none of these will work well wirelessly — the magnets only align properly with iPhones. You’d be better off with a standard power bank that has multiple USB-C ports and a higher capacity like 20000mAh for longer trips.
For most iPhone users, I’d grab the COOAV — it gives you the full 12000mAh capacity, the fastest wired charging at PD 22.5W, and triple-device charging for the best value in this group.
Frequently Asked Questions
Which of these three power banks has the fastest charging speed?
The COOAV takes the crown here with its PD 22.5W USB-A output, which is slightly faster than the 20W PD on both the CHUSII and HHETP. For wireless charging, both the COOAV and CHUSII support up to 15W, while the HHETP maxes out at just 7.5W. If raw speed is your priority, the COOAV is the clear winner.
Is the CHUSII worth the extra money over the COOAV?
That depends on what you value. The CHUSII costs significantly more but gives you a digital battery percentage display and a built-in kickstand — features the COOAV lacks entirely. The COOAV, however, has faster 22.5W wired output and charges three devices at once for less money. I’d only pay up for the CHUSII if you really want that kickstand for hands-free video watching.
Does the HHETP really have a smaller battery than the other two?
Yes, and this is a key difference. The HHETP packs 10,800mAh, while both the COOAV and CHUSII have a full 12,000mAh. That 1,200mAh difference means the HHETP will give you slightly less runtime — roughly one less partial charge for an iPhone 16 Pro. For most daily use it’s still fine, but if you need maximum battery life, go with the COOAV or CHUSII.
Which power bank is the lightest and most portable?
The HHETP is the lightest at just 0.46 lb, which is noticeably less than the others. It’s also the most compact at 3.99 x 2.59 x 0.78 inches. The COOAV is still slim at 0.7 inches thick but weighs more. If you’re slipping this into a small purse or shirt pocket every day, the HHETP is your best bet.
Can these charge non-iPhone devices like AirPods or Android phones?
Yes, all three can charge other devices through their USB-C or USB-A ports. The wireless charging is specifically designed for MagSafe iPhones, so non-MagSafe cases or Android phones won’t attach magnetically. For wired charging, any device with a USB cable works fine — I’ve charged AirPods and Samsung phones through the USB-C port on all three without issues.
Which power bank is best for travel and long flights?
I’d pick the COOAV for travel because it has the full 12,000mAh capacity, the fastest 22.5W wired charging, and can juice up three devices at once — perfect for sharing with travel buddies. It’s also airline-approved and slim enough at 0.7 inches to fit in a carry-on pocket. The CHUSII is a close second if you want the kickstand for watching movies on the plane.
My Final Verdict
The COOAV is my clear winner — it delivers a true 12,000mAh capacity with the fastest PD 22.5W wired output and can charge three devices simultaneously, all at a price that undercuts the CHUSII significantly. The CHUSII is the runner-up and best for travelers who want a kickstand and battery display, while the HHETP works for budget shoppers who don’t mind the smaller 10,800mAh battery and slower 7.5W wireless charging.
If you’re still on the fence, ask yourself this: do you want the most capacity and speed for your money, or do you need a kickstand for hands-free use? If it’s the former, stop overthinking and grab the COOAV. You won’t find a better balance of features and value in this group.
