The review says that the magnets in MagGo Nano Power Bank are strong. But does anyone know if they are strong enough to hold the powerbank to the phone with a case (TPU, thickness 1 - 1.5 mm)?
I have Spigen case for 15 Pro as below. I also bought that Anker MagSafe nano power bank. I have to say, the magnets they put in this tiny thing are one of the strongest I deal with in MagSafe accessory. If I want to remove the power bank from the phone, it is easier to do it by sliding it to the side than by pulling it towards myself. But it won't go away easily, that's for sure.

The only thing I don't like about the nano MagGo is that the LED indicator is very dim. I might have gotten a lemon?
 
Anker's new Nano MagGo Slim Power Bank 5K doesn't look all that impressive. There are other brands offering similar power bank products that are even slimmer and lighter, and for half the price -- e.g. Baseus Picogo Power Bank, 0.3" Ultra Slim 5000mAh MagSafe Portable Charger. Or does Anker's thicker, heavier power bank offer some significant advantage that I'm missing?
The newer model which is Qi2, is $49.99 which isn’t much cheaper than the Anker Nano MagGo Slim 5k power bank.

Isn’t the nano power bank the same as the MagGo power bank? Is this just a package refresh with a different name? Only difference is the available colors. If you buy the one on the Apple site you do save $5.
 
No thank you. Sadly I thought were a good company and fell for flashy marketing and [paid] vlog recommendations.

It's a tad less simple than that.

The US government page that addresses this says:

Units:
About 481,000
...
Incidents/Injuries:
The firm has received 33 reports of fire and explosion incidents. Four minor burn injuries and one report of substantial property damage have been reported.


I mean, it's not irrelevant but it really feels like this kind of very-high selling brands are the only ones that can get statistically relevant data in a 1/14K case of fire hazard. That they themselves reported to the government, which is also reassuring and I'm not sure all brands you'd find on Amazon would, even if they sold enough devices to even notice a pattern.

I have the reviewed powerbank and I use it a lot. It’s thin but even more importantly the magnets are strong enough that it doesn’t come off the iPhone when I put it into my jeans pocket. That makes it a no brainer to strap it onto my iPhone when I leave the house in the morning.

That being said it’s not good at charging up the iPhone wirelessly and instead it’s only really useful to me to keep the charge at 100% for as long as possible. That’s a slow trickle charge that the powerbank can keep up with.

If you slap this on at 20% and expect to get anywhere you can forget that. I tried that as I was out traveling in the summer and the iPhone was already quite warm at that point since I was using it to navigate my way around and the powerbank merely kept it at 20% as both iPhone and powerbank kept heating up. There’s not gonna be any 15W charging with that amount of heat generated.

But of course that’s where you’d need the powerbank the most, when you’re out traveling. Inside with AC there’s no issue but if you test it there be aware it won’t actually perform like that in real life use.

I do still recommend this power bank as it does give me about a 50% extra charge on my small 15 Pro without adding much bulk. You just can’t trust advertising claiming 15W and whatnot, it might do that for a few minutes before it heats up and charging crawls to a halt.

If you turn the display off while it charges from 20% then it does make slow progress. But I really recommend that you keep it on all the time and let it slowly deplete over a few hours. Basically it’s like taking the iPhone off the charger at noon instead of 7am. That’s almost half a day of extra power.

I have tried other power banks and thicker ones always slide off in my pocket way too easily or they’re just too bulky. This one doesn’t do much but it doesn’t get in the way either. It’s a good product overall and I haven’t found a better powerbank yet.

But if you want to charge an empty battery wirelessly it will just generate heat and you’d be sitting there waiting for an hour. With a cable I am sure it works much better but I don’t buy a wireless power bank just so I can connect a cable so I haven’t tried.

It also charges the AirPods charge case wirelessly and holds the case in place but the magnetic force isn’t as good so it will come off more easily.

Perhaps this helps someone decide what they can expect and whether to buy this. I think it’s good enough as I explained and I recommend it overall. Definitely will disappoint customers who just expect real fast 15W typical charging. It can do that in lower temperatures for sure but not indefinitely. By the way, the iPhone never shows the slow charger warning, seems the powerbank does communicate full 15W capacity. Simply from the very long charge time I can deduce that it’s definitely not doing 15W continuously.
 
I recently picked up the Anker Nano 10k magsafe for wired charging of phone/airpods/laptop/watch

I consider the magsafe feature to be my convnience/backup for charging.

I also have Apple's original magsafe battery and the new Air magsafe battery for my Air. I prefer either one of those for magsafe battery extender / charger.
