WINSINN Removable 24V 40W Heater Cartridge 620 Ceramic Hotend Works with Creality Ender 3 5 CR10 CR-10 CR10 Anet A8 3D Printer (Pack of 5Pcs)

These are nice replacements for my CR10S Pro V2 printer. I like the JSTM connectors, converted my heater and thermistor to these connectors. Some have said they are a concern because they theoretically pull 3.33 amps at 12V DC. Doubtful this is an issue at all given the very short time they would ever pull full a full load during initial heating ramp. Rated at 3 amps continuous. At 24V it is even less of an issue only pulling 1.6 amps max. I see other people reviewing about melted connectors. Must have pulled a lot more amps, possibly a dead short in their wiring or some other failure. My connectors and wires don't even get warm at max load.

I used these on my e5+ and this is a much better solution for my printer. I cut the stock wires and soldered this in with the connector closer to the hotend. Now it's easy to replace if I need to.

I’ve had to change multiple heater cartridges in my day and having them quick connected just outside the hotend has been a game changer. No more fishing wires through the entire machine to change a bad heater cartridge. Just unclip it and add a new one to the wiring. Is don’t plan on using the longer wires now that they have been installed but I will use the shorter actual cartridge for easy swaps. All wires on 3d printer should be like this.

I've used these for my neptune 3's they work perfectly. And function as intended.

I ordered these to go with: https://www.amazon.com/dp/B099KRXSX4 - Thermistors. I Popped the 2-pin headers out of their housing and added them to a 4-Pin JST-SM connector with the thermistors for a rewiring project. Initially I was concerned that they would melt based on some of the other reviews. It looks like the ones that melted were 12v cartridges with higher amperage. The JST-SM connectors can handle the lower amperage of the 24v carts, I have been using these for a few weeks now, and the housing for the JST-SM connectors does not get any warmer than room temp.

Connectors on short portion of cables are not JST-SM connectors, as seen in the product description. The ones on the long portion are. Cable quality does not match pictures, they have it wrapped in better heat protection, and wrapped better to the heating cartridge.

Product is exactly as described!

Comes with wrong connector and cheap wire(which is somewhat dangerous) It supposed to be fiberglass sleeving wire but it was not. Idea was good but quality of this item is not.

Good price and quick delivery.

Item is exactly as pictured and fits and works perfect. Most of all I love the idea of being able to change out the heater without changing out all of the wiring each time. Worst thing is that you can guarantee that a time will come when you have to change out the heater and with this it is one click and slide in the new one and you are off to the races and printing again with minimal down time and maximum return.
