Ultra-Slim Qi2 Magnetic Power Bank

The Anker A1665 is a 5000mAh lithium-polymer power bank certified for Qi2 wireless charging at up to 15W. It magnetically aligns with compatible iPhone models for cable-free top-ups and also provides up to 20W wired output via its USB-C port. At just 0.33 inches thick, it is built for daily pocket carry without adding bulk.

Graphene Cooling and Temperature Control

A graphene cooling layer and dual NTC sensors actively regulate heat during charging sessions. The manufacturer states the surface stays below 104°F, which is 14 degrees cooler than the referenced industry standard. This thermal management supports sustained 15W wireless speeds and 20W wired output while keeping the slim chassis comfortable to hold.

USB-C Cable and Documentation Included

The box supplies a USB-C to USB-C cable for recharging the power bank or powering other devices over wire. A welcome guide covers basic operation and the 24-month manufacturer warranty terms. No wall adapter is bundled, so users will need an existing USB-C charger to replenish the 5000mAh cell.

Questions about this item

How do I attach and charge the Anker A1665 to my iPhone, and what is the common mistake?

Snap the power bank magnetically to the back of a compatible iPhone; the 15W Qi2 wireless charging starts automatically. The step people miss is pressing the side power button to begin the wireless session.

What part of the Anker A1665 will need replacement first with daily use?

The internal 5000mAh lithium-polymer cell degrades over hundreds of charge cycles; the USB-C port and magnetic array are solid-state and typically outlast the battery.

At what temperature does the Anker A1665 throttle output during sustained charging?

The graphene cooling and dual NTC chips keep the surface below 104°F, about 14 degrees cooler than the industry reference, so thermal throttling rarely activates in normal use.
