Mini UPS Module – 5V/3A or 12V/1.2A Output, Uninterrupted Power Supply for Electronics Projects
The Mini UPS Module is a compact uninterruptible power supply available in two options: 5V/3A or 12V/1.2A. It supports 1–2 Li-Ion 18650 batteries in parallel and provides seamless switching between external power and battery without interruption.
It is suitable for routers, IP cameras, development boards, IoT systems, sensors, mini-PCs, or any device requiring stable 5V or 12V power. During operation, the module can power the device while charging the battery simultaneously. On power loss, the transition to battery is instant, without resetting the equipment.
Available Versions
Mini UPS 5V/3A – ideal for Raspberry Pi, ESP32, Arduino, IoT modules.
Mini UPS 12V/1.2A – for routers, IP cameras, controllers, and 12V equipment.
Main Features
Instant UPS switching (zero delay) – uninterrupted power supply.
Supports 1–2 18650 batteries (in parallel).
Power input via Type-C – up to 3A (higher current than MicroUSB).
Efficient booster: up to 96%, 20W peak / 15W nominal.
Complete Li-Ion protection: over-discharge, overcharge, short circuit, temperature.
Dual LED indicator: red = charging, green = fully charged.
Compact dimensions: 88 × 41 × 22 mm.
