What is the difference between X1205 and X1200:

• X1205 uses a wide voltage power input (9V-18V);
• Solves the overheating problem of DC jack power supply
• Uses a higher capacity 21700 lithium battery to provide longer power supply time;
• The power supply capacity through the DC jack is greatly increased from 5.5A of X1200 to 10A

Misc	Connects to the Pi via convenient pogo pins, eliminating the need for additional cabling Designed to be attached on the bottom, allowing the use of favorite HATs alongside it XH2.54 connector available for adding your own power button
Power Supply Tips	The Wide 6-18V Input allows the user to choose the power supply flexibly. The required current is greater than or equal to 3A. The reserved 6-18V XH2.54 connector provide convenient power supply when integrate this ups shield with other products. A good quality power adapter is very important,Most of the problems you encounter are usually caused by using a poor quality power supply.Strongly recommend Geekworm 12V 5A Power supply
Notes	Only DC Jack power is enough, DON'T apply power to your Raspberry Pi 5 via the Type-C USB socket. Do not use 21700 battery with built-in protection circuit.

Hello, I am using a PoE and NVME hat. Can I still use a X1205 as UPS?

Yes, you can use them together.

You'll just need to check physical mounting compatibility, GPIO pin compatibility, and avoid any serial port conflicts. Also make sure your power supply is sufficient, since your setup has a relatively high load.

We don't have enough details to give a more precise answer. If you need further help, please email us at support@geekworm.com with a full description of your issue — ideally with photos or videos included.

Hi, i'm would like to know, if i can use this HAT without RPi 5 on pogo pins and only XH2.54 5V socket used, since i'm have another board. Thanks!

Hi there! The X1205 doesn’t support this function for now, and we’d recommend you consider the X1206 instead.

The X12-UPS series has an auto power-off function when no Raspberry Pi 5 is detected, while the X1206 lets you set the "Always Power On" mode – it keeps working even when your Raspberry Pi is shut down.

Please refer to Interface ⑩ ALON in the picture[1].

You can also consider the [2]X-UPS1—it features a GPIO Pin-Connected standalone design (refer to the pic [3]) with high flexibility for installation and adaptation.

i bought the x1205 a few months ago, has been working fine until last week, when i started having shutdowns. i use it with geekworm dual nvme hat. i disconnected the board and sprayed contact cleaner, after which it was working ok for a day, then suddenly one of my nvme's dropped off. i previously had a similar issue with x1200 which is the reason why i upgraded

Hello! We’ve received your question. To pinpoint the issue, our first step is basic troubleshooting:

① What are the specifications of your power supply?

② Are there any other devices connected to this UPS?

We initially suspect the shutdown of only one NVME drive is due to insufficient power supply. We recommend trying a DC-powered power supply rated at 12V/3A or higher.

Based on the current information, we can only make a basic assessment—we’ll need your additional feedback to further identify the root cause (Contact us at support@geekworm.com if needed).
