I need help buying a laptop charger

In My Humble Opinion
1

I got a good deal on an open box laptop, but it didn’t come with a charger.

So I checked the bottom. It says input is 19.5V 3.34A/4.62A.

What does that mean, does it mean it can accept either 3.34A or 4.62A? Because while looking at chargers I saw some that were 19.5V but they said they could do 3.34A but not 4.62A. Will a 4.62A charger do them both? I know that works out to 65W or 90W, but thats a pretty big difference and I don’t want to buy a 65W charger if its going to try to pull 90W.

Also how do I find out for certain what kind of plug I need to plug it into the laptop itself?

Here is some info about the laptop.

Dell - Inspiron 15.6" 7000 2-in-1 Touch-Screen Laptop - Intel Core i5 - 8GB Memory - 512GB SSD + 32GB Optane - Silver

Model I7591-5476SLV-PUS

SKU :6373038

Should I just buy a universal laptop charger set for 90W that does 19.5V and has a wide range of connectors?

I’ve tried searching the model number, name, SKU, etc and it shows me chargers but I don’t know if those are actually for this particular model.

Here you go - several are listed at 65W 90W for the Inspiron 15 7591.

When it comes to laptop power supplies, it’s generally better to just google the laptop model plus the word power supply. Trying to go by voltage or amperage isn’t all that useful, since you also have to get the exact right plug and everything.

I tried that, but I couldn’t find one that explicitly included my laptop. But I don’t know what factoids need to be included.

Inspiron 7000, Model I7591-5476SLV-PUS. Does all that need to be there?

I’m sorry. I thought it was clear that @SpoilerVirgin had found a compatible charger for your device. My comment was more a general comment about how to find any particular laptop charger. In general you look up the model number for the laptop, rather th

What I found searching was that it does indeed mean it can accept either amperage. The smart chip in the power supply will tell it which one you have. I suspect that higher amperage will charge faster, so I would definitely use @SpoilerVirgin’s link. The only thing I might use instead would be an official Dell charger, but those get expensive:

One thing to consider: it may be able to be powered from the USB-c port (check the manual or specs for something like “USB power delivery”; I’d strongly bet it can, based on looking into buying a similar model four months ago), which means you can buy a kinda-universal USB-c charger. Just make sure it can provide enough power for a laptop and not just a cell phone.

[You can also go full-hog and get a box that connects to the laptop’s USB c port and not only powers it, but also connects an external monitor and keyboard/mouse, if that’s your thing. The official Dell version is a lot more expensive than 3rd party ones]

In my experience, if the AC adapter is under-powered, a Dell system will display a warning before booting that it will run the processor at less than maximum performance.

Thanks, I just ordered one.

thank you, that charger model is working fine. just got it set up.

I’ve successfully bought aftermarket chargers for other laptops before but I was having trouble with this laptop model for some reason.

I have a Dell Inspiron 2-in-1 in the 17-inch version (I’m using it to type this reply), and have ordered several chargers for it, so I knew how to find one. I’m glad it’s working for you.
