I received today 23-Dec-2018. Wire is not silicon as advertised. It is normal plastic casing.

The display I received works for 30 minutes and then goes off. I had another display from another supplier and it is working till date. So I recommend you to buy from Sparkfun, Adafruit or ebay where they give good service. They will replace your products or refund you back. But here, too many questions and and they forget about it.

These modules does not work properly. Over charge the battery. Uses a fake TP4056 chip on them, not the original NanJing Top Power TP4065. Original chip https://lcsc.com/product-detail/PMIC-Battery-Management_TP4056_C16581.html

jinantha Good review Thanks

This board will probably provide adequate power for a Raspberry Pi 3 provided any additional hats, etc consume virtually no power. I plugged the board onto a Raspberry Pi 3 and plugged it into a 5v power supply and allowed the battery to fully charge. I attached a low power USB drive and then booted into Raspbian with a monitor, mouse and keyboard attached. It booted but I kept getting the low voltage warning on the monitor. I checked the power consumption of my set up by attaching it to a bench power supply and it was just under 2 amps, so the UPS hat should have been able to cope. I then took an oscilloscope to the 5v supply coming from the UPS to the Raspberry and found that it was spiking below 5v. I then disconnected the UPS from the Raspberry and power supply so that it was running purely from the battery. I simulated a load of 0.5A / 500mA as shown in photo (1) at which point the 5v supply had a 100mV ripple but averaged about 5.2v as seen photo (2). I then simulated a load of a little less than 1A (actually 918mA) as shown in photo (3) at which point the ripple became slightly increased and the average voltage dropped to 5v as shown in photo (4). After a few seconds negative spikes started to appear as in photo (5) which I think would be enough to trigger the under voltage warning on the Raspberry and potentially cause issues. To summarize, I would not rely on this board to power anything more than just a bare Raspberry.
