INTELLIGENT DESIGN: UPS for Raspberry PI 4B / 3B+ / 3B. Built-in power path management, support side-loading, load high current line compensation function. There are two USB A port power output, and also adds type C output. It provides uninterruptible power for the Raspberry Pi to make your Raspberry Pi still work while moving, and its design is so smart that you can get rid of troubled of a mass wire.You can check the Wiki link in the Product guides and documents at the bottom of the page.

MULTIPLE PROTECTION: Support output overcurrent, overvoltage, short circuit protection; input overvoltage, overcharge, overdischarge, overcurrent discharge protection and machine overheat protection. Safe and reliable

USE AND NOTE: This product belongs to the power supply device. Please keep it out of the reach of children. Please strictly refer to the instructions for the UPS product, install the battery first, then connect the UPS to the Raspberry Pi. Please do not reverse the battery. If the battery polarity is reversed, it will directly burn the power management chip of the device. Do not add any Components by yourself
