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)

Product is working great!

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.

Perfect for adapting new styled connectors to older styled cords.

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...

Ordered wrong size, but will keep in the parts bin.

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

Although this can power a Dell Laptop by connecting a Dell Laptop Charger with a 5mm male to a Dell Laptop with a 3.00 mm female connector, this AAOTOKK Tip Adapter Cable cannot charge a Dell laptop because the third center pin wire doesn't not have any continuity which is required by the Dell Laptop circuitry to recognize a Dell Laptop Charger.

It is excellent but i don't need it

purchased two Dell mini PC's from ebay with no power supplies, but I had one HP same output and purchased another Dell power brick of ebay and used this adaptor on both. some laptops may complain about power supply in the bios but my mini PC's didn't.

I really only needed one of these, but have found a use for the other to save space. I will keep it on my tech bench, eliminating another charger/power cord.

Perfecto. Cumple su cometido

Alles OK, passt. Aber Achtung: der Lader muss das bringen was nötig ist zum laden des (neuen) Laptops. Z.B.: mein neuer HP hat ein 230W Lader. Mein alter HP wurde nur mit einem 120W Lader gefüttert. So passt der AAOTOKK-Kabel auf den alten Lader(Kabel), kann den Laptop nur laden wenn dieser ausser Betrieb ist! Beim Arbeiten lädt er nicht! Ich glaubte einen Ersatzlader zu sparen, da ich noch 3 alte (wie neu) hatte ...

I have 2 genuine Dell laptop power bricks with the exact same ratings. Sadly one has a larger plug so I got these adapters. I was hoping to keep one charger at home and one at the office so I won't ever be without one. It fits my charger and laptop perfectly but sadly doesn't work as I'd hoped. The laptop registers that it's being powered but the battery still drains slowly. In the kit are 2 adapters and both of them have this issue. It's much better than no charger at all. On battery alone on medium power settings I could work about 5 hours. With this adapter I can work on full power settings all day and end up with about 1/3 battery left at the end. Which isn't bad but means I won't make it through the next workday.
