So i had the 10k mAh magsafe one and it works decent maybe 3/5 stars.

I say decent bc it does charge, but it doesn't allow for fast charging and won't charge if its connected to a modern fast charger (65W+), it does allow for it to be slow charged and it took about 5-6 hours to fully charge. The magnetic magsafe portion is also pretty strong. I use it to keep my teams awake when I'm at the beach and it'll last me a day or so and it's not a magsafe fast charger either but a slow one(? I think).

It also doesn't charge via my desk's magsafe which is kinda odd.

Also, this 5k mAh one is $14 but the 10k magsafe one that was on sd a week or two ago (just search lisen and it should be one of the top listings) was only $18 so $4 more. I'd rather just wait for a 10k one instead as it has more utility.

Your lightning port is probably clogged with linen, dust, debris. Gently remove visible debris with a plastic toothpick or a soft brush.

Mainly, I like that I can charge my phone in my pocket without worrying about putting pressure on the cord or phone port, but there are other situations where the inefficient charging with worth making the phone and power bank one object vs walking around with fragile nunchucks.

Community Reviews

The slim LISEN MagSafe power bank stands out for its pocketable size, strong magnetic attachment, and handy cable free charging when a phone port is broken or worn out. It fits recent iPhone Pro models cleanly, can charge a phone while the bank itself is charging, and the compact build makes it easy to carry or use in a pocket. The main tradeoffs are slow wireless charging, limited real world capacity, and noticeable heat, with some reports of battery drain or early failure. A compact convenience pick if speed and capacity are not the priority.

ive been looking for a CCC certified one and they seem to be pretty rare in the US. i guess most are in fact CCC certified but they just dont put the logo on there because they dont really need to.

i guess the best way is still just to buy one when u get to China.
Here's one from the same brand. Says CCC certified right in the title. https://www.amazon.com/LISEN-1000...0FLKG7329/

Wireless charging is already very inefficient, I don't know why you would use wireless charging with a power bank. You're already limited on power, might as well charge it the most efficient way.
Shit, I didn't realize it was wireless. Thanks!

Are they both the same thickness?

You'd use the wireless charging if the charging port on your phone was broken. Like mine. Like I do.

Be careful if you are planning to use it in China. It is not CCC certified according to some customer reviews.
People are clowning on this comment but it genuinely helped me, I was planning on getting this to travel to China and wasn't aware of CCC, so thanks.

Or take to a repair shop to clean, but lightning ports don't have a prong to bend so less risky to clean.

Any recommendations for a lightweight, small 10,000 mAh portable charger bank? Thanks.

These are not Qi2 or Qi2.2 so you're getting the slowest (7.5w) possible charging out of them. I just went down the Magsafe PowerBank rabbit hole and ended up going with the Energizer unit from Best Buy (5000 mAh, $17). It's also metal construction and thin but it's Qi2.0 so it can charge at 15w. I'd be nervous to charge faster than that with how hot these can get. https://www.bestbuy.com/product/e...J36C4YX4LJ The 10,000 mAh unit is only $20 but I didn't want the added bulk.

IS it heavy?
No, I purchased some of these 2 times in the past when they have been on sale, 8/25/25 and 1/29/26. I find them to be compact and lightweight. I have been very happy with these and have given them as gifts. They don't have a large capacity but they do fully charge the phone and are light and compact which is why I have bought them, also because of the price. They make my phone a little warm but not hot.
