Hp Laptop Power Supply Not Charging

Plugged into HP power supply with a 7.4mm plug and was able to charge a HP laptop with with a 4.5mm charge port.

works with and without the power supply. Need the power supply for charging devices.

Laptop shoulder bag provides protection and easy of transportation for my new 17” laptop, power supply, wireless mouse, as well as papers and documents.

It's a power supply.

Fast charging power bank, which charged my laptop at least two times.

I was in need of a power supply for my Fujifilm dual charger because just any supply will not allow simultaneous charging of both batteries which defeats the whole purpose of a dual charger. This one does.

The Celestron PowerTank is a very versatile power supply. It offers a variety of charging and light options. This a useful power source addition to any celestial viewing trip.

This is a handy device. I use two of them. One is attached to an Apple Airport with Time Machine and another is attached to an Airport Express. The former connects to three hard drives and has one plug free to charging a device in a convenient location. The latter connects to two printers (a wide-format pro photo printer and an everyday all-in-one) and has two cables for charging devices. The printers and hard drives are all accessible, simultaneously, from my entire collection of Apple devices. This is amazing! I wouldn't use them all at once as the strain on the wireless network is great but who needs them all at once? The USB hub powers the hard drives and transfers data to the printers fast for faster printing. The charge cables plugged in to it use the devices own power supply (included) and can charge an iPad as fast if not faster than the Apple-supplied power supply. The hubs are small, easy to locate or place, and come with their own power supply to make external or portable hard drives easy to use. It allows fast charging. The plugs are well put together and are not difficult to use - that is, they allow plugging and un-plugging easily. The hub is lightweight and seems well built. It comes with a nice cord to attach to a parent device and if I had to remove it from the device and take it on the road it would be great to toss in to a bag or backpack. Great purchase and would buy again.

Works beautifully, no surprises ... Of course I'm using it , not for a laptop, but a condenser tube mic's power supply that sits at the bottom of a big Atlas studio mic stand on wheels Perfection !

Great power supply.
