10 Pack Ac Power Cord Charger Laptop Adapter Tip Connector Converter for HP Stream Spectre Pavilion Envy EliteBook Split Chromebook EliteBook Folio Female 7.4x5.0mm to 4.5x3.0mm

Tried a few of these and this is the only one that actually charged, at a decent rate, our 135w laptop, 2 others maintained power when using the laptop and 1 slow charged but this one almost duplicates the original in charge speed so brilliant. Highly recommend.

Perfectly converts the older HP laptop supply into a more useful bluetip. Advise using some heatshrink to provide a more robust connection between the two.

Bought to allow flexible use of existing, rather than specific charger.Seems well made and works, not much else to say.Cheaper than buying a new charger!

Works perfectly to charge my laptop. Only reason it's not 5 start is because the metal contact sticks out further than the original charger, but this does not impact the usage at all. I imagine it's probably to be more comapatible with other models perhaps

Happy with the Amazon delivery and return process. This connector is advertised as working for HP but does not work with my HP EliteBook. if there are exceptions on the compatibility it would nice to report it in the notice avoiding to buy and return goods.

Great little converter will save the expense of a new cable when you upgrade your machine. Eco friendly!Also handy for this times when you can find your charger... But it's not the right one!

It really does provide a perfect connection, great quality product and works well with HP ZBook Studio G3.

Works well converting old Dell power supply to new 15 XPS laptop.On the 90W power supply get warning message since expect 130W, but still charged laptop without problems.
