## At a glance

- Four built-in cables cover USB-C, iPhone, Micro USB and USB-A connections, according to the listing.
- The listing claims up to 22.5W output and says compatible phones can reach 50% in about 30 minutes.
- A digital display shows remaining charge, and the listing says it supports low-current mode for small devices.

## Pros

- Integrated cables and additional ports can reduce the number of separate leads needed when charging several devices.
- 20,000mAh stated capacity and a charge display help when planning longer days away from a mains socket.
- The stated kit includes a travel pouch.

## Cons

- At 340 Grams, it may feel bulky to buyers seeking a very light pocket charger.
- The manufacturer says it is not compatible with laptops. Its 22.5W maximum output is aimed at phones and smaller devices rather than laptop charging.

## Before you buy

- The manufacturer says carry-on air travel is allowed but advises against packing it in checked baggage. It also says some warmth during charging is normal and to stop use if temperatures exceed 45°C \(113°F\).
- The listing says the fixed USB-A cable can recharge the power bank when connected to a wall adapter. It claims charging up to six devices at once, but the separate connector details specify four built-in cables and four ports while another field lists six ports. The two listed dimensions also differ, so check the selected listing for the exact configuration and size. The claimed 50% phone charge in about 30 minutes applies to compatible phones, and actual charging depends on the device and conditions.
