This keeps my server running if there is any power issues or i feel like taking the device with me when traveling. I used a recycled laptop battery pack to source a 18650. I get about 3-5hours runtime from 1 2200mah 18650 with power settings on the pi set low as possible with minimal server utilization. Review: sends no data to the pi, but works well. - fits battery nicely, charges well, pi zero 2w works for hours with no issues. ## Features - Enhanced Battery Holder: X306 V1.5 (Oct 2025) upgrades the battery holder for smoother installation, removal, and long-lasting reliability (battery is not included) - Compatibility: Compatible with Raspberry Pi Zero 2 W ONLY, NOT support Raspberry Pi Zero/Zero W; Model: X306 V1.5; Matching Case: X306-C1 is the compatible case for X306 V1.3 and V1.5 - One-Cell UPS HAT: Ideal Uninterruptible Power Supply (UPS) solution for Raspberry Pi Zero 2W, Max 5.1V 4000mA Power Backup with single cell battery holder(battery is not included) - How to Power: Power via USB Type-C 5V Power In port of X306; 5Vdc +/-5% , ≥3A; Use Geekworm UL listed 20W 5V 4A USB Type-C power adapter - Cooling Solution: Recommend to use with C296 aluminum heatsink for Raspberry Pi Zero 2 W - Packing List: 1 x X306 Expansion Board; 4 x M2.5x5mm screws(Raspberry Pi and Battery NOT Included) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B74NT38D | | Amperage | 3 Amps | | Battery Cell Composition | Lithium Ion | | Battery Cell Type | Lithium Ion | | Best Sellers Rank | #524 in Single Board Computers (Computers & Accessories) | | Brand | Geekworm | | Color | Black | | Connector Type | USB Type-C | | Customer Reviews | 4.4 out of 5 stars 57 Reviews | | Enclosure Material | Plastic | | Form Factor | Compact | | Frequency Range | 50/60 Hz (± 3 Hz) | | Input Voltage | 5 Volts (DC) | | Item Dimensions | 3.03 x 2.56 x 0.39 inches | | Item Weight | 39 Grams | | Manufacturer | Geekworm | | Material | Plastic | | Maximum Power | 20.4 Watts | | Mfr Part Number | TB-2022-56 | | Model Number | TB-2022-56 | | Number of Outlets | 3 | | Output Current | 4000 Milliamps | | Output Voltage | 5.1 Volts (DC) | | Output Wattage | 20.4 Watts | | Power Plug Type | No Plug | | Runtime | 8 hours | | Unit Count | 1.0 Count | | Voltage | 5.0 | | Warranty Description | 3 months | | Wattage | 15 watts | ## Product Details - **Battery Cell Composition:** Lithium Ion - **Brand:** Geekworm - **Color:** Black - **Material:** Plastic - **Voltage:** 5.0 ## Images ![X306 V1.5 5V UPS Expansion Board for Raspberry Pi Zero 2W | Max 5.1V 4A Backup Power, Not Include Raspberry Pi and Battery - Image 1](https://m.media-amazon.com/images/I/718M7n6B6-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice little unit *by J***S on April 6, 2026* I have a mqtt server running on a Raspberry Pi Zero 2W.
