Slim 10,000 mAh Power Bank

The Anker PowerCore Slim 10000 is a 10,000 mAh lithium-polymer portable charger finished in black. It measures 6.01 in by 2.82 in by 0.61 in and weighs 0.53 lb. The unit supplies one USB-C port and one USB-A port for both input and output, supporting fast charging up to 10 V at 3 A. It is supplied with a USB-C to USB-C cable and an 18-month warranty.

Travellers and Daily Commuters

The slim profile and airline-friendly capacity suit people who need reliable phone top-ups during flights, long meetings or weekend trips. Two-way USB-C charging lets the bank itself recharge quickly from the same port used to power devices. Users who require multiple simultaneous high-wattage laptop charges or capacities above 10,000 mAh should consider larger units.

Capacity and Output Headroom

A full 10,000 mAh cell delivers roughly two full charges for an iPhone 15, 1.93 charges for a Galaxy S23 and 1.23 charges for an iPad mini 6. The combined 30 W output comfortably handles two smartphones or a phone plus a small tablet at once. Sustained high-power laptop charging will exhaust the bank after a single partial session.

Questions about this item

What cable do I need to recharge the PowerCore Slim 10000 from a USB-C wall charger?

Use the included USB-C to USB-C cable plugged into the power bank's USB-C input port and a compatible USB-C wall charger.

Can I charge an older phone that only has a USB-A port at the same time as a newer USB-C device?

Yes, the power bank has one USB-A output and one USB-C output, so you can connect a legacy USB-A cable and a USB-C cable simultaneously.

How can I confirm the 10000mAh capacity is delivering the expected number of charges for my iPhone 15?

An iPhone 15 should reach full charge about two times from a fully charged PowerCore Slim 10000 under normal conditions.
