Description

With the Bluebuilt Power Bank with Fast Charging 20,000mAh Black, you can fully charge your smartphone about 4 times. Thanks to fast charging, you can charge iPhone models and Samsung smartphones extra quickly. After half an hour of charging, the battery is charged for 40 to 50%. With the button on the power bank, you can easily check on the display how much battery you have left. The cables for Android smartphones and the iPhone 15 or newer is included in the box. Have an iPhone 14 or older? You need a USB-C to Lightning cable. You can also charge your tablet 1 to 2 times. Want to charge a laptop as well? Choose the BlueBuilt power bank with 27,000mAh. This power bank is less easy to take with you on the go, because it only fits in a bag. Thanks to the useful carrying cord, you can bring your power bank with you even more easily.

A well-functioning and handy product.

Charge Samsung Galaxy S21 more than 4 times
Compact (for its capacity)
Charge mobile quickly
Charges very slowly on its own

Just about fits in your pocket. Quite bulky and heavy, though it is one of the smallest in its category.

Good value for money Charges my mobile (Samsung Galaxy S21) more than 4 times Charges the mobile quickly, but charging the power bank takes a very long time (over 5 hours!)

Handy for on the go

Compact
Fast charging
Only 1 short cable is included

Ideal charger for on the go, but the website and the box state that 2 cables are included. However, only 1 short cable is included.
