Why is my power bank providing fewer charges than expected?
The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker A1610 Battery (PowerCore 5K) offers an estimated 2,750mAh~3,250mAh to power devices.
How can I estimate the number of charges for my device?
To estimate charging cycles, use these formula:
(Power Bank Capacity × 0.5) ÷ Device Battery Capacity ≈ Number of Charges.
For instance, charging a 3,000mAh device using a 5,000mAh Wireless power bank would offer approximately 0.83 charges.
Why does charging stop at 80%?
Your iPhone may automatically stop charging at 80% to protect its battery from overheating, as part of iOS 17’s thermal management strategy. Charging will resume once the device cools down. Moving it to a cooler spot can help speed up this process.
Why is my phone overheating?
It’s normal for devices to warm up slightly during wireless charging, particularly with heavy use like extensive gaming or streaming. Rest assured, this device meets international safety standards for safe operation.

Dependable!!
This is a great product and I am getting much use out of it. I carry it in my edc bag and it comes in handy when my phone is about to die and I donât have access to an electrical plug. I have about 4 of these made by Anker.

High quality and super useful
Super cool device. I absolutely love how light this is. Itâs easy to carry on an outing or while traveling. Kind of feels like an Apple device in that itâs substantial and built well.

Remote charge backup
Itâs Ok, I fully charged before using and used the battery to my IPhone. It charged but not to 100% only 75% charged. Good to have the charge in a pinch.

Beware Of The Overheating of this Anker Battery!
Need to be honest here. I own a lot of Anker products, and have never had an issue with any of them until I bought this battery. You have to be very careful of this product when it’s magnetically attached to your iPhone. This product overheats quickly, and frankly it is alarming. Not only does the battery overheat, it causes the iPhone (a 16 Pro in this case), to overheat to dangerous levels. I have stopped using this battery since purchasing it in 2024 as I believe it’s massively defective.

Not a fast charger, and get very HOT
Works as advertised, just didnt realize it would be such a slow charge, and both phone and charger get VERY hot.If you’re looking for a quick charge, or full charge, this isnt it.Will get you a decent battery charge if you dont use your phone and allow it to charge for 3-4 hours without a cable however.
