What I like:1) 3 different ways to charge a deviceYou can charge either using the USB-A/USB-C ports on the side or the Qi charger on the front. This means I can always grab this power bank when I'm heading out, and it will be able to charge every device I have without having to put too much thought into what particular cables I'm bringing. It's even more convenient for me since I have a few devices that use Qi charging, so I don't usually need to bring a cable at all.2) The screenAll of the other power banks I have use 3-5 lights to indicate their level of charge. This will give you the level of charge down to the granularity of 1%. It's nice to have when discharging, but also unexpectedly nice to have when charging in a hurry, since you can see exactly how close to 100% it is (unlike other power banks, where the last light is blinking but you're not sure how much longer there is to go).3) Good MagSafe integrationI use an iPhone 12 Pro Max with a non-MagSafe case on. Even still, the magnets on the power bank are still strong enough to easily align with the iPhone through the case and begin charging it without too much fuss. Putting my iPhone on the power bank also triggers the MagSafe charging animation in iOS, which is nice to see.The power bank has a depression at one end to accommodate the giant camera bump, and the screen is also located here. That's a subtle way of incorporating the camera bump into the design in a way that isn't obvious, which leads me to my next point...4) Well-considered physical designThis was a bit of a surprise to me, since most power banks are just plastic enclosures around a battery and some ports. But this power bank actually had some effort put into its design, which I noticed right away.The power bank is very solidly built - no flexing or creaking anywhere. The plastic has a soft matte texture that doesn't attract fingerprints, and there's a subtle circular symbol to indicate where the charging coil is centered for non-MagSafe devices. The interior of both the USB-A and USB-C ports have matching orange accents, which is a really nice contrast with the black. There's a small light blue LED (a nice departure from the typical dark blue LEDs on electronics, by the way) on the side of the device, between the USB ports, that illuminates solid when the device is awake if you can't see the screen (e.g., if your phone is on top of the power bank). And the white LEDs used to display digits on the screen have a nice retro look and are invisible when the screen is off.Of course, none of this really matters that much from a functional perspective, but I do appreciate products that have clearly had care put into their design, and this is one of those. Not enough companies do this.What I don't like:Honestly, I have no real complaints from my time with it so far. It serves its purpose with flying colors.Other notes:The battery goes to sleep and the screen turns off to conserve power after a minute or so. There's a nearly flush button on the side of the power bank to wake it up. The button is quite large and easy to find/press.I haven't field tested the battery backup/charger to see how long it holds its charge. I have used it to charge my phone at home when a couple of my cords went bad.My primary complaint upon initially working with the product is that the manual is printed in the tiniest of fonts sizes and is nearly impossible for my 60-year-old eyes to read, even with my bifocals. Really, the font could stand to be a few points larger.I like the fact that it fits perfectly and looks good with the slim design on my iPhone 13, but it is a little thick when on, although not too thick to where you can't hold it in your pocket. One thing I don't like but doesn't bother me a crazy amount is the fact that the display faces the phone when attached. It is a little bit annoying to have to take it off or rotate my phone every time I want to check the percentage on the charger. It also charges fairly slowly but doesn't lose percentage when on and charging which I think is a really important detail. It does charge while on and charging but really slow. I know this sounds (from how I described) kind of a bad product but overall for 30$-40$, this is a really fair and decent product. The display and magnets really give you a luxurious feeling and a great addition with the small amount paid. Thank you for taking the time to read my review.Great for a spare of the moment charge. Back up only. Not capable of fast chargingMy boyfriend loves it he uses it everydayWorks like a charmGreat battery pack! I used this with my iPhone 12 Pro and an otter box MagSafe case. Magnets stick pretty well but aren’t the strongest I’ve seen.Product is a little misleading.. THIS IS 10,000 mAH AT 3.7V! Since our phones typically use 5V you have to convert it…10,000mAh x 3.7V / 5V = 7,400mAh.The charger does really charge with PD 20W. Charged my iPhone 12 Pro from 0% to 55% in 30 minutes and drained the battery pack down to 76%.Fully charged my iPhone twice with 2% left on the battery pack.Fast charge attaches in pocket together while charging. Agreeable that the magnetic is weak but charges faster than mag safe apple charger 15w. So far so good, phone should be idle or one place to be charging common sense lol theirs other crap batteries for sale with strong magnetic if that’s what you’re looking for ?
