Anker 325 Power Bank (PowerCore 20K) — Black
The Anker 325 Power Bank (PowerCore 20K) is an ultra-high capacity dual-port portable charger built for travelers, commuters, and anyone who needs to keep phones and tablets powered for days without an outlet. Its 20,000mAh cell capacity delivers roughly 5 full charges for an iPhone, close to 5 charges for a Samsung Galaxy S10, and over 2.5 charges for an iPad mini 5. Twin USB-A output ports let you charge two devices simultaneously, while PowerIQ and VoltageBoost technology optimize charging speed for whatever’s plugged in. A Trickle-Charging Mode — activated by pressing the power button twice, or holding it for 2 seconds — delivers gentler charging suited to low-power accessories like earphones and Bluetooth speakers. Anker’s MultiProtect safety system covers overcharge protection, short-circuit protection, and temperature control throughout.
