Holy Stone 4-in-1 Battery Charger and 4Pcs 3.7V 750mAh Rechargeable Li-Po RC Drone Batteries for F181C

Batteries suck. Get maybe 3 or 4 flights of 3 to 4 mins. Then nothing.

I'm only using this charger now for the first time, and it seems to be working OK. However, there is a significant defect with the unit in that the top plate is rotated 180 degrees (see photo), so that the icon for the USB port is at the opposite corner, and the indicator lights are backwards (the blue light is the power light but appears as port 4, while the light labeled as power is actually port 4, etc.). Unlike other reviewers, I find the lights are bright enough, although this is indoors in somewhat low light. The connectors seem a little touchy, so that if you bump the unit, some of the connectors get disconnected even though they appear to be still plugged in. Not hard to fix, but mildly annoying.

I used this battery charger and the batteries for two years and found that they worked very well and without difficulty.The charging was complete in about an hour. The batteries maintained their charge well. It is a great help to have extra batteries available and charged when flying the HS 200 drone.

I received this as a replacement for the small black one I ordered that didn't work very good (Holy Stone 5 in 1 Max 2.5A Current Input Fast Battery Charger for X5C, 818a,X1,X4,HS170,X300,X400,F181,F180 Quad Copter).This one is a lot better! better built and reliable. I have had no problems with it. Buy this one!As an aside, their support is as good as people say, excellent! This is why I chose Holy Stone for my purchase. I have not been disappointed.
