10000mAh Power Bank with Built-In Cables

This 10000mAh power bank integrates three charging cables and an AC wall plug so you can leave extra cords and adapters at home. It delivers 20W USB-C fast charging for iPhone, Android phones, tablets and other USB devices. A digital display shows the remaining capacity at a glance. The slim profile measures 5.9 by 2.8 by 0.55 inch and includes a carrying case for travel.

Capacity and everyday headroom

The 10000mAh cell comfortably recharges a typical smartphone two to three times before the bank itself needs refilling. Tablets and larger devices will consume more of the reserve so expect roughly one full tablet charge. When the bank is depleted you can recharge it directly through the built-in AC prongs without hunting for a separate wall adapter.

Thermals noise and power draw

Passive cooling keeps the unit silent during charging and discharging cycles. The compact enclosure stays warm but not hot under the 20W maximum output load. Power draw from the wall matches the 20W USB-C delivery rating so the AC plug does not demand a high-current circuit. No fan or moving parts means zero audible noise in normal use.

Questions about this item

Will the built-in USB-C cable and 20W output charge my older phone that only supports standard 5V charging?

Yes, the 20W USB-C output negotiates down to 5V automatically, so your older phone will charge at its normal speed using the built-in cable.

How do I confirm the power bank is delivering the 20W fast charge to my compatible device?

The digital battery display shows real-time output status; when a 20W fast-charge session is active the display reflects the higher power draw.

Does the package include a separate wall charger or do I only use the built-in AC plug to recharge the 10000mAh unit?

No separate wall charger is needed; the built-in AC plug folds out to recharge the power bank directly from a mains socket, and a portable carrying case is also included.
