ESRfor MagSafe Power Bank, 0.55 in Ultra-Compact 5,000mAh MagSafe Portable Charger, Qi2 Certified 15W Ultra-Fast Battery Pack, 20W USB-C MagSlim Charger with Cable for iPhone 17/16/15/14/13/12, Black

Great item, esr do produce good quality products, magnets are strong, sits on the phone nicely, charges quickly, not too heavy, and very stylish. Charges very well and quickly.

It’s not too big and heavy and doesn’t make your phone uncomfortable to use or carry in your pocket.

This power bank has many positive features.For example, it provides very fast charging speeds, which is useful when you need to quickly charge in a short space of time. It also is very easy to use and works well, turning on as soon as it comes into contact with an iPhone. and comes with very clear instructions on how to use the product and what the lights mean. The capacity of 5000mah is enough for normal usage and allows an iPhone to be charged enough to get you through the day.It doesn’t get too hot when charging; it just gets moderately warm, which is good compared to most other MagSafe power banks that I have tried. The design looks very good, with a nice clean design. It feels very high quality and well designed. It also is fairly light and doesn’t add too much extra weight to your phone.However, there are some things I don’t like about it.Firstly, the size. It is a fairly chunky product. Granted it is slimmer than a lot of other MagSafe power banks, but I was personally looking for a very slim one, and this wasn’t quite slim enough. The size of this product can be seen in the photos (with iPhone 13 Pro for reference)Secondly, the button. The power button on the side of the product is slightly loose. This doesn’t sound like a big deal, but when you receive a notification, you notice it. It just makes the product feel a little cheap, even though every other aspect of it is amazing.Overall, I would still recommend this product, although the button is something I would like to see improved upon in the future as it is a little annoying.

This is the fastest power banks I’ve had - wired I’ve seen it charging at 23w. Wireless it went as high as 13. I think your phone can limit the charge rate. It can also charge your laptop for a brief period. I highly recommend this as a charger.

Good works well

Great price and well built. Perfect.

I'm very unsure with this product. It heats up my phone quickly and my phone becomes unusable.

Charger works and looks nice but is second hand so I don’t know if it’s at full battery health or not. Does get quite hot but I hear that’s normal for wireless charging.Edit: increased stars as ESR customer service replied straight away and were really lovely and helpful.
