All-in-one power bank with built-in cables

The Luvknit PS38K is a 20000mAh lithium-ion power bank that integrates USB-C, Lightning and Micro-USB cables so you can charge phones and tablets without carrying extra cords. It suits travellers, campers and anyone who wants a single device for daily top-ups and emergency backup. A dual LED flashlight adds utility in low-light conditions.

22.5W fast charging via USB-C port

The single specification that decides fit is the 22.5W USB-C output, which can bring a compatible smartphone to roughly 70% charge in 30 minutes. If your device does not support this rate or you need higher wattage for laptops, this unit will not meet the requirement.

Steady output under continuous use

Under sustained load the bank maintains its rated 5V 3A delivery across the USB-C and standard USB ports while powering multiple devices at once. The 20000mAh cell provides enough reserve for several full phone cycles before the integrated solar panel or a wall charger is needed to replenish it.
