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.

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.

How do you keep teams alive?
display auto-lock time set to never. Open teams and leave the screen on.

An actual machine audit will give you away due to button clicks and/or movement screenshots on your computer so ymmv

My iPhone 13 started having problem charging with cable and but ok w wireless charging. I have a power bank which can charge iPhone while itself is charged. That is very useful
Mine too. Cable port is too janked up from using the cord to fish the phone from between the bed and the nightstand. And full of pocket lint.

Not good at all. Heats up very quickly and does not even charge an iphone 12 for 50% battery. Returned back to Amazon after giving it few tries.

Can't help but laugh at their big selling point in one photo that says "Lasts at least 2 years" 😂

The slim one sucks. It charges wirelessly so slowly that it barely breaks even with flagship phones from the last couple years.

If one was looking for Slim ones which ones are to go for?
