AAOTOKK Tip Laptop Power Adapter Cable DC 7.4mm x 5.0mm Female to 4.5mm x3.0mm Male Charging Connector Power Converter Cable DC Jack for HP Notebook Adapter Replacement Power Cord(15.8cm/2Pack)

It is excellent but i don't need it

The adapter worked right away and no drama. Other adapters did not fit the HP computer properly - this one did.

This adapter came up when I searched for Dell 7.4 to 4.5mm adapter, but it is not compatible with Dell, only HP. This is due to it not passing through the middle pin which allows the adapter to tell the laptop how much power it can provide. Both brands use the middle pin for this, but they do so differently. This adapter has HP identification in it for 65w to prevent too much power from flowing through it if the brick it is used with can provide more than 65w. This obviously doesn't work with Dell laptops. The 65w setting can also be a problem if you use a brick than can supply less than 65w in which case the laptop will try to draw too much power potentially damaging the brick.

There are two types of connectors of Dell power. I bought this adapter so that I don't need to buy a new power.

Did not work on my HP Victus 4070 AMD gaming laptop. I checked voltage with my multimeter and I see 19V so prob not the adapter, but some dumb thing about the laptop... thanks hp...

I had several power supplies that were for a previous HP computer, but did not fit my new computer. The amperage and voltage ratings for the supplies and the computer were the same, but the plug was different. I ordered these adapters and they allowed me to use the existing power supplies with my new computer, which saved me a great deal of money versus buying additional power supplies. I have used these adapters for several months now, and they have performed flawlessly. I would definitely recommend this product.

Fits perfectly, able to charge my hp laptops with existing power blocks I already had.

The exposed metal (see red arrow) is a short circuit vulnerability. The laptop power cable barrel plug should be completely insulated when the 7.4mm x 5mm adapter is attached.
