Overview
The UGREEN PB312 (25683) is a 20,000 mAh power bank for keeping phones and tablets going across a trip or a long weekend, with a number display that shows the percentage left. It has one USB-C port for charging and recharging and two USB-A ports, so three devices can share it. It is a wired, everyday power bank rather than a laptop charger.

Before you buy
- It does not deliver 20 W plus 22.5 W plus 22.5 W at once.
- No wall charger is in the box.
- Pass-through adds load and heat; charge a device from the wall directly when you can, and do not rely on pass-through for equipment that cannot tolerate a power interruption. It is not an uninterruptible power supply.
- Allowed in cabin baggage at 74 Wh.
- Use it within the conditions on the label; the power bank or device may reduce output when warm. Built-in protection is a backup, not permission to use damaged equipment or block ventilation.
