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.

  • The slim MagSafe-style power bank fits iPhone 16 Pro and iPhone 17 Pro/Pro Max without protruding or cutting into the camera bump.

  • The power bank can charge an iPhone while the power bank itself is charging, which improves convenience during travel.

  • The magnetic pocket charging setup can reduce stress on the phone's charging port when cables are inconvenient.

    ThriftyStag5104

  • The power bank can serve as a workaround when a phone's Lightning port is not working, allowing wireless charging instead.

    Estebanuser1

  • The wireless charging speed can be very slow, including charging at the slowest ~7.5W level.

  • The power bank can heat up quickly and may leave heat marks in a dark case.

    jaildecayjatslickdeal

  • The power bank can fail early or drain an iPhone battery even while plugged in.

    chenquistadorhek

  • The power bank does not support fast charging and it can take about 5-6 hours to fully recharge.

I have three of these two from Lisen and one from another. You're lucky to get 3000 out of them. They are hot and will burn a mark in a dark case.

Mine just crapped out in less than 50 charge cycles. Feels good quality but probably isn't.

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.
I got this Baseus 20000mAh [amazon.com] for $23 last month when it was on sale. It has the CCC logo on it but, as expected, it is quite heavy to keep in my pocket.

I have never had problem at any airport custom inspection when traveling around the world with my portable power banks (up to 20000mAh) so far. But I heard that China had recently increased their restrictions so I don't want to risk it. Keep in mind not all power banks sold in China have the CCC logo on them.

Stay away from it! Got the same one — my iPhone 16 Pro's battery drains even while it's plugged into this charger.

You are right. Not a good quality charger

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.
Good point. In my case my phone lighting port does not work, (as many other user, as it is a common issue to god bad) and I do not want to purchase a new phone. Mag safe charger work like a charm as an alternative.

Be careful if you are planning to use it in China. It is not CCC certified according to some customer reviews.
I don't think I've seen a single thing on here that is ccc certified

Agreed. I am waiting on a good deal on a power bank that uses magnetics for attaching itself to the phone and has a built in charging cord.

I think it'll be th best compromise on ease of use and charging efficiency.

There are a few power banks on Amazon like that, but seem overpriced for now.
