20 000mAh portable charger

This power bank stores 20 000mAh of capacity and delivers up to 30W output through a built-in USB-C cable. It is suited to travellers and daily commuters who need reliable top-ups for phones and similar devices without carrying separate cords.

Capacity and charging limits

The 20 000mAh cell can charge an iPhone 15 up to 4 times or a Galaxy S24 3.79 times before the bank itself needs recharging. A 30W output brings an iPhone 15 from 0 to 57% in 30 minutes, while 20W input refills the bank quickly; devices that require more than 30W will not reach their maximum charging speed.

Built-in cable durability

The integrated 5.98-inch USB-C cable is rated for over 10 000 bends, eliminating the need to pack a separate lead. Users who prefer a detachable cable or need a longer reach for awkward sockets will find the fixed short cable limiting.

Questions about this item

Will the built-in 5.98-inch USB-C cable charge my iPhone 15 at the advertised 30W speed?

Yes, the integrated cable supports the power bank's 30W two-way fast charging, delivering up to 30W output to compatible devices such as the iPhone 15 series.

How can I confirm ActiveShield 2.0 is monitoring temperature during a charge cycle?

ActiveShield 2.0 performs 3 million temperature checks per day and automatically adjusts power output; normal operation with no overheating indicates it is functioning correctly.

Does the package include a separate wall charger for the 20W input recharge?

The box contains the Zolo Power Bank with its built-in 5.98-inch USB-C cable and a welcome guide; a 20W or higher USB-C wall charger must be purchased separately to achieve the fastest recharge speed.
