Features
1. PoE UPS Base For CM4: Uninterruptible power supply, powering the CM4 while recharging
2. Connecting With Compute Module 4: Standard CM4 socket and color-coded Raspberry Pi 40PIN GPIO header. Suitable For Compute Module 4 Lite/EMMC Series Module
3. Uninterruptible Power: It is able to charge the batteries and provide power output for the system at the same time from external power supply. Automatically switch over to batteries output if external power supply is unavailable, keeps the system running without any trouble
4. Multi Power Supply Options:
- Three external power supply options: USB interface, wide voltage DC, and PoE
- When connected to the external power supply, the system will be powered and the battery will be charged at the same time, and the battery will be in a disconnected status after being fully charged, so as to avoid battery life damaging caused by frequently charging and discharging
- When the external power supply is insufficient, the battery will provide power output together with the external power supply at the same time to ensure system normal operation
- When the external power supply is connected, the system will keep running normally even when the battery fails or is taken out. When the external power supply is disconnected, it will automatically switch over to batteries output without interrupting the system operation
5. Safe And Stable Circuit Design: Protection circuits for over charge/discharge, over current, short circuit, and reverse-proof
along with the standalone resettable fuse for each battery, more safe and stable
6. Real Time Monitoring: Monitoring the batteries voltage, current, power, and remaining capacity via I2C. (When the voltage dips too low, it is possible to save files properly and then shutdown the system by software, to avoid any data loss)

Note: The 18650 batteries are not included

Great purchase
Material Type: Recycled Polyester, Color: Dark Navy, Size: X-Large
Purchased several shirts, all were great quality. You never know what you’ll get when you purchase sight unseen, these are worth it. Great value, style, and comfort. Color is exactly what you see online. True to size.

For work or casual wear, this polo is a great choice.
Material Type: Recycled Polyester, Color: Port Stripe, Size: X-Large
I really like this polo. I've been wearing it once a week or every other week since November. Its very comfortable and breathable. This polo feels like it should last a while. The fit is good. I typcally wear XL and this XL fits great. I've pruchased it in both burgundy and black so far. I definitely recommend this shirt. For work or casual wear, this will look good.

Great value: These are my go-to work from home shirt
Material Type: Recycled Polyester, Color: Blue, Size: X-Large
I’ve been pleasantly surprised by these shirts and wear them weekly for Zoom calls, since I’m still working from home these days. I figured at the price point it was worth trying them out, and now I’ve bought several in different colors. They aren’t super soft, but they are comfy and look nice. I’m 6’1” ~220 pounds, and the XL slim fit still has plenty of room. I imagine the regular cut is incredibly boxy and oversized. The difference between polyester vs recycled polyester is inconsequential. I typically buy expensive golf shirts, and these definitely aren’t as nice. They are a fraction of the cost though and a great “beater” work shirt / hang out shirt. It’s nice wearing something that looks and feels decent, but if something happens to it, you can toss and it and pick up another for the cost of a chipotle burrito.

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.
