==Updated==
X306 is updated to <span class="tb_red">V1.5 version</span> on August 21st 2025: A higher-quality 18650 battery holder is used, making battery installation and removal easier and more robust. X306 is updated to V1.3 on May 28th, 2024.</span>
Please check the information on the page on the sales platform to confirm the version you will get.
* Removed 4-pin header for external power swtich and always-on power option(Users have less need for this. Can can solder it yourself if needed)
* Smaller size, simplified use

* 4 blue LEDs indicate battery charging and discharging levels of 25%, 50% , 75% and 100%
* Red & green LEDs show the status of power on/off and charging status
* On-board push button to control power on /off (<span class="tb_red">'''Press-ON, Hold the button pressed at least 3s -OFF'''</span>)
* Ultra-low standby power consumption of μA to maximize battery life
* Advanced system power path management avoids frequent charging and extend battery life
* <span class="tb_red">When use with X306 '''V1.1''', '''DO NOT''' connect any device to the Micro USB OTG port of Raspberry Pi Zero 2W</span>, or the USB2.0 ports of X306 is not available to use.

==Matching Case==
The Geekworm X306-C1 is a premium metal case specifically designed for use with the Raspberry Pi Zero 2W and Geekworm X306 V1.3 UPS board. Crafted with precision and durability in mind, this case provides a sleek and protective housing for your Raspberry Pi Zero 2W project. [[File:X306-C1-IMG-97429736-Packing-List.jpg|700px500px]] ===Test of the impact of the casing on WiFi signals===It should be noted that the metal shell will have a certain shielding effect on WiFi, and the farther the device is from the router, the greater the effect will be. We tested the effect of metal casing on Wi-Fi signal, and the results are as follows: '''Test Result:'''{| class="wikitable"! With X306-C1 metal case !!

'''Test subjects''': X306-C1 metal case '''Test Method''': We flashed the Raspberry Pi OS Legacy (6 May 2025) version and used the script [[File:Wifi-signal-monitor.zip]](download and unzip it) to obtain the WiFi signal strength with and without the X306-C1 metal case. '''Other notes''': The Raspberry Pi Zero 2W motherboard is about 3.5 meters away from the router, with no obstructions in between. Use the script wifi_signal_monitor.sh to test '''2.4GHz or 5GHz frequency band''' :Since the Raspberry Pi Zero 2W only supports the 2.4GHz IEEE 802.11b/g/n WiFi band, you can only access 2.4GHz SSID hotspots. Based on the above test results, we can draw a conclusion: X306-C1 can meet the needs of devices using 2.4GHz Wi-Fi '''when close to the router''', which should be attributed to the larger heat dissipation hole design on the surface of the X306-C1 shell.
