PiSugar 2 Plus 5000mAh Portable UPS Battery Pack for Raspberry Pi 4 3B+ 3B

5000mAh Raspberry Pi Battery for Pi 4B/3B+/3B, 5V 3A Stable Output- The PiSugar 2 Plus is a reliable Raspberry Pi battery pack with a 5000mAh rechargeable Li-Po cell, delivering stable 5V 3A output for NAS/VPN servers, screens, SSDs, and SDR/LoRa dongles. Extensively tested on Pi 4B/3B+ for stable, reliable, cool operation, it gives 46 hours of backup on light headless loads (runtime varies by workload) ideal for Pi-hole, retro gaming, and 24/7 projects. The PH 2.0 cell is field-swappable for easy replacement. ^^ Hardware Raspberry Pi UPS with 0ms Switchover & Safe Shutdown- A hardware Raspberry Pi UPS detects power loss and switches to battery in 0ms with no reboot, triggering auto safe shutdown to protect your SD card and data.

Supports charge-while-discharging (pass-through charging) and auto-powers on your Pi when utility returns. Keeps Pi-hole, IoT, field monitoring, and headless servers online through outages. ^^ Live Battery % in WebUI, HTTP API & On-board RTC- Unlike basic fixed batteries that cannot report charge, the PiSugar 2 Plus shows live battery %, status, and voltage in the WebUI or over HTTP, so you always know runtime. An on-board RTC keeps time offline and schedules timed auto boot with no network. The adjustable I2C address helps avoid conflicts with other HATs.

^^ Magnetic Tool-Free Mount, Full GPIO & Cooling Friendly- Secure magnetic alignment plus four screws lock the board to the back of your Pi and hold the bottom SugarPin pogo pins firmly in perfect contact, with no shifting on portable or in-vehicle builds. The 4-screw, solderless, tool-free setup needs no extra hardware, uses zero of the 40 GPIO pins, and never blocks the CPU heatsinkleaving full room for Ice Tower coolers, fans, sensors, LoRa/SDR dongles, LED strips, and any Raspberry Pi HAT. ^^ Dual Charging, Custom Button & Expandability- USB-C and Micro USB dual ports support pass-through charging, with pads for solar and Qi wireless charging for off-grid use.

The programmable button maps single/double/long press to any shell command. The WebUI and HTTP API also let you set low-voltage shutdown and charge limits for safer, smarter power management. ^^ Wide Compatibility for Every Pi Maker Project- The PiSugar 2 Plus Raspberry Pi UPS powers popular
Pi builds: NAS/VPN servers, Pi-hole, retro consoles, cyberdecks, weather stations, trail cameras, IoT deployments, and STEM kits. Works with Raspberry Pi 2B/3A+/3B/3B+/4B (NOT for Pi 5, Pi Zero/Zero 2 W, or Orange Pi), with guided WebUI setup that makes it the smart UPS battery upgrade for makers who monitor, schedule, and automate power.
