2Pcs DC Power Adapter Cord Tip 7.4mm x 5.0mm Male Plug Connector Adapter Pigtail Cable for DELL HP Laptop Power Adapter Replacement 30cm

Fit my Dell Wyse 5070 perfectly, not too loose or too tight. I had one minor issue but I don't know if it was related to the power supply I used or these plugs, the color-coding wasn't white to white and brown to black with my power supply so I had the polarity reversed...but again that might have been the power supply I used not these, not sure. Sends the correct blue wire data signal so the CPU isn't throttled, so this works great. A good deal and I bought another set that I've also used.

What really impressed me was the quality of the materials used to manufacture this plug. Soldered and attached well to the existing cable on the Dell OEM power supply. Does it's job well. Keep in mind the blue wire on the power supply side is more there for reinforcement and contains stranded nylon cords which smell and char if not removed before you attempt to solder them. They are only on the Dell power supply side and in my application the blue wire is otherwise non-functional in my application.

No problem splicing in and it has been working well.

I bought this which came in a set of two hoping to use another adapted for my Dell. What I did not know is the center pin sends a special code to your computer letting it know that it's a Dell adapter connected and the specifications of that connection including voltage and wattage.I had to return mine because the off-brand adapter did not have the proper dell signaling to work properly. That's my fault. That being said, these are quality replacement tips, and fit well in the DC port. So, if your plug is broken, this is the one to get.

Not even close to a Dell adapter. Far too big. Going back.

Excellent for replacing damaged tips on certain Dell laptop chargers. These fit snug when pushed into laptop's charging port. Each includes 3 wire conductors with tinned wires.

The original adapter has 5 wires: two black, two white and one green. I spliced one of each of the black and white wires of the original adapter with the black and white wires of this cord, and the green wire with the blue wire ("signal" wire). Now my laptop is charging again and I avoided buying a new adapter from Dell which costs around $200.

My Philips Dreamstation 2 CPAP now has an emergency power alternative since I wired this to a pair of alligator clips. A deep cycle, trolling battery should give me a full night's rest even when the grid is down.
