Product information

Description

The 4smarts 541626 portable power bank supplies 20000 mAh of Lithium Polymer (LiPo) energy in a compact grey housing. It includes two permanently attached USB-C cables, an extra USB-C port and a USB-A port, supports Adaptive Fast Charging, Hisilicon FCP, Power Delivery 3.0 and PPS, and can charge multiple devices at once while also recharging itself.

Advantages

Built-in dual USB-C cables plus an additional USB-C and a USB-A port let you charge up to four devices simultaneously without extra adapters. Pass-through capability allows the power bank to recharge while powering connected devices. An integrated LCD shows remaining capacity as a percentage and indicates active fast charging. At 321 g and 10 × 7 × 2.5 cm, the unit is compact and travel-friendly while offering 77 Wh (20000 mAh) LiPo capacity.

Suitable for

How to use

Connect your device to one of the integrated USB-C cables or to the USB-C/USB-A ports. If you need to recharge the power bank while still charging devices, plug a USB power source into the power bank’s USB-C input; the pass-through function will supply power to connected devices while the internal battery recharges. Use the LCD to monitor remaining capacity and the fast-charging icon to confirm high-power delivery.

Usage recommendations

For longest battery lifespan, avoid exposing the power bank to extreme temperatures, and store it partially charged if not used for extended periods. Use compatible fast chargers and cables to utilize PD/PPS charging safely.
