the crimping plier is not suitable for JST XH connector. JST XH connector require a naarow die thickness, this plier is suitable for only dupont connectors. Since JST XH conectors also part of the kit, they should have included JST XH die for this Plier. otherwise the kit is good for Hobby work.

sekar amir its very sad to note Banggood also going along with supplier by removing the photo. they should take proper judgment and if supplier is designed it wrong which causes damages to the battery, Banggood should raise their voices along with customers instead of protecting them!!!

I would not recommend using this power bank with standard Li-Ion batteries as it is configured to charge up to ~4.4V. This significantly decreases the life expectancy of the cells and increases the risk of a fire while charging. Luckily, you can desolder a SMD resistor, as shown in the attached picture, to set the final charging voltage to 4.2V. Other than that, the power bank is ok. Build quality is not super accurate but good enough and once you've assembled the unit, it's really hard to pry it open again. That means that changing the cells is difficult, but the unit should be able to survive falling off a (small) table. I could not get the power bank to charge with QC3.0 though. The maximum it seems to be using is 9V with 1.7A, so roughly 15W. And when using a second power bank of the same type to charge the first one, it will only charge with 5V and 1.9A. At 15W it will take 5-6 hours to charge it up completely if you are using ~3000mAh cells. Charging other devices with the power bank seems to work fine, though, I don't have any QC compatible devices to try that. A Oneplus 3 will be charged with 5V and approximately 1.4A. Various other devices (Action camera, EBook reader, ...) are charged with 5V and 0.5A up to 1A. One other weird thing is, that the power bank will somehow calibrate it's percentage display during the first startup (inserting the first battery). If the cell voltage is around 3.6V, it will show 3.8V as 100% charged. You need to insert cells with a voltage of 4V in order to have a remotely correct value.

This powerbank uses a charging voltage of 4.4V. After testing, I can confirm, that this powerbank will not stop charging, when the batteries are full (4.2V) and continue charging, so your batteries will overcharge and they might even explode. Luckily the charging voltage can be corrected to 4.2V, by removing one of the tiny SMD resistors. By the way, quickcharging the powerbank seems to work only with 9V ~1.7A. Sadly, I got no other quickcharge capable devices, to test the output of the powerbank, but as I ordered two of these powerbanks, I connected one of them to charge from the other one and there was not quickcharge at all (5V 1.9A).
