I've used this power brick 4 times now. It holds enough power to recharge my 14 ProMax 1 time. That's all I needed it for, so I'm happy. I love the ease of use, how I can just attach it to the back of my case and my phone recharges. I like that it's slim and not cumbersome. The whole unit warms slightly when charging the phone, but it's not enough to worry about.

At basically the same capacity as most modern smartphones, its a good option if you just need to top off while on a trip or doing some activity out and about in a pinch. Its fairly light, easy to fit in your pocket, slim and easy to take you with you anywhere you go. But its only going to charge you up maybe once. Don't count on this if you take a long trip and need portable battery power to recharge multiple times or multiple devices. This is meant to be a one charge, one device type of accessory and its great at that!

Works well but can occasionally run very hot.

3/22/25: Update after customer service reached out to me. They offered a replacement or full refund. I chose replacement as I’ve always preferred this brand. So far the replacement has worked well. Great customer service and product is as expected. Would recommend. Huge plus over others is the slim design. Fits nicely in my phone holder in the car. Still gets warm when using but only if you are using the phone while charging it which is to be expected with any charger. I genuinely felt the Anker brand was superior to others so I bought this and gave my son the one I had. For this price, I would not recommend. Fully charged, it charged my phone less than 50% before dying. It took over 2 hours to do that and was hot after a short period of time. It also takes forever to get it fully charged. On the plus side, it is slim and fits nicely in my hand and phone holder.

I never go anywhere without this charger. It is lightweight, thin, and so easy to charge my phone with no cables necessary. It gets used almost every day - if not by me then by a friend nearby who needs a quick power boost!

Mounts to phone with relatively good strength, but positioning is finicky, even in the best case charging is constantly cutting in and out. Wireless charging speed is OK, and battery is plenty durable. It will charge itself and the phone at the same time while plugged in, and the phone correctly detects whether it is plugged in or not. Initially, it was good for about 1 full charge, almost doubling phone battery life, but after less than a year of use, battery life has dramatically declined, being less than half of what it was at the start.

Item stopped recharging after less than 3 months of use. It started having issues after about 60 days, but now won't recharge at all. When it was recharging, it seemed to recharge much slower than other batteries I've owned and then when used it seemed very slow in charging up my iphone. I checked out the troubleshooting and it appears that the lack of recharging issue is a common issue. Its totally unusable after less than 90 days of use and the troubleshooting tips aren't working. Buy another product.

Great product. Very slim and handy to toss in my purse for when I need it.

No queda a la medida en el iPhone 15 pro , buena carga minimalista y delgado pero buscaré otra opción

Leicht, gute Kapazität, sehr gute Verarbeitung (wie von Anker gewohnt). Hat einen Stammplatz in meinem Rucksack und beim Reisen!

Great item and does the intended job. Doesn’t last as long as my previous portable charger but is very handy to have and easy to carry around. It does get a little warm while charging if you’re also using your device so better used when not using your device. Not having a cable to charge is very handy and is less to carry around with you, but does come with its own. Magnet strength is good, charges through a standard case. Good value for money.

Żona zadolona.

Batterie très fine qui ne prend pas de place. Suffisante pour recharger son iPhone une fois.
