🔌 HKBAYI 50 Pair / 50 Sets 3-pin JST SM Male Female Plug LED Connector Cable for WS2812B WS2812 WS2811 LED Strip Lamp with 15cm Wire Length Review

Inexpensive plugs but as other reviewers say the wires in these plugs are thinner than advertised so you will likely experience some voltage drop. I had to run more power drops than expected to keep the color consistent.

Bought and paid for 50 sets but received 46 female and 50 male ends. Also, I found that many of the sets (which were supposed to ship with 50 pins and 50 pins in one package) were poorly assembled as the pins had to be rearranged within the pin ends to match the pin ends. All in all I can get them to work and I'm not worried about the four missing connectors that I have to return to Revain, but buyers beware, the quality and quantity of these cable/connector sets will not earn many 5 star…

I wanted to use these to power a 300 LED strip. While the ports offered a decent connection when plugged in, I had to sift through a few to find a good one. Unfortunately, the cable got very hot under load. I assume that if I split the 5m strip into 1m strips everything would be fine. But to be honest I was worried about the isolation for the full track. Looking at the wire and comparing it to known AWG I would expect it to be in the 26 AWG range. As a rule, the power is not considered suitable

So I've been looking for a lot of JST connectors and I mean A LOT. After encountering repeated issues with long runs, including with the power supply, I started working on anything that might be causing the problem and then came up with testing these plugs. On average - a plug connected to an outlet, and the included cord has a resistance of more than ONE ohm! The pins in the plug can break in any weather, and the wire should be around 26 AWG - if that. They have a few stranded copper wires…

It wasn't until I soldered these connectors to dozens of prototype panels that I realized how poor the quality was. When connecting the panels in a chain, the voltage drop was also unacceptable on the 2nd panel. Finally, I set up a test setup to measure resistance across a pair of connectors. The average resistance was about 400 mΩ. It's huge. The maximum contact resistance for JST-SM connectors should be around 20mΩ, and the resistance for 1 foot or 22 AWG wires should be around 17mΩ. I cut a…
