Anker's smart charger launched
In January 2026, Anker launched the Nano 45W charger with a smart display. It shows charging status and communicates its thermal state through different animations.
Why temperature matters for batteries
Battery health is directly tied to temperature. Battery degradation accelerates at higher temperatures, so Anker's smart power adjustment technology keeps things in check before they get out of hand.
Three thermal status displays
Breezing shows the charger is under one hundred thirteen degrees Fahrenheit and operating normally. Floating indicates active temperature monitoring to prevent increases exceeding one hundred forty degrees Fahrenheit.
Cooling mode and Care Mode
When the charger detects high heat, Cooling mode automatically reduces charging speed to cool itself down. Care Mode is designed for night charging to keep temperature below safety limits and reduce battery aging.
Floating mode keeps batteries healthy
If your Anker Nano 45W charger displays Floating mode, it is actively protecting your battery. The charger's internal sensors are doing their job to prevent damage from excessive heat.
“It's not a warning sign or a malfunction, but rather the charger's way of showing that its internal sensors are doing their job.”
The short version
Anker's Nano 45W charger shows thermal status through animated displays. Floating mode indicates active temperature monitoring to prevent battery damage.
