Geekworm X306 V1.3 UPS Expansion Board for Raspberry Pi Zero 2W (Not Include Raspberry Pi&Battery)

I really like these things not only does it add portablity to your pi zero projects but it adds some usb ports and it acts as a UPC when plugged into mains power.

UPS worked great. However, I could not get USB hub to work at all, so I had to return.

Maybe it's obvious to everybody else, but you have to use the batteries without a button top.

I got the v1.3 variant of this board (only compatible with Raspberry Pi Zero 2W).I should have paid more attention to another review that mentioned the battery holder is very tight because mine snapped with no warning while trying to insert an 18650 cell. The plastic is brittle and the metal contacts don't bend much at all, leading the plastic holder to flex tremendously while inserting the battery. The manual's only information on what 18650 cells to use is in the FAQ "What 18650 battery is recommended?", and the answer is just dimensions in millimeters. To anyone unfamiliar with 18650's, the recommended length of 65.3mm would probably disqualify all 18650's with built-in protection circuitry. After my experience, this "recommendation" should be a requirement that's clearly listed on this product page.Battery holder aside, this seems like a good UPS for the pi zero 2 that adapts the power in to USB-C instead of the Zero's disappointing micro USB. If the battery holder could be made more robust, this would be a solid recommendation. But until then, don't buy unless you're comfortable risking breaking the brittle battery holder.

Does the job.

Careful, even cap-less 18650s are a tight fit and I have had the crack that cheap plastic carrier...Also, make the damn USB carrier data!Also, sell one without USB and double 18650!!

Works great with a Pi Zero

Works great as a portable power pack for the Pi Zero 2, and that is the primary reason I bought this. Unfortunately, none of the USB ports on the hub are working at all. This wouldn't have been a big deal since I'm fine with using the onboard micro-USB port on the Pi but when this product is installed, the micro-USB port doesn't work either. So at this point I have no USB capability at all which means I cannot use this product for my purpose. Hopefully customer service gets back to me with a solution.
