Question Im trying to connect a Presario CQ70 laptop to a 200watt solar pannel, the plug supplied woith the solar pannel didnt match up, what do I do now?

So the plug from the solar panel manufacturer was too big to plug into my laptop, I've already bought a universal adapter with a 2 way cable, but what is the proper way I should do this, my presumption was that the solar panel will never produce enough electricity anyway to blow my laptop so all I need is some kind of universal adapter?

With the adapter you seem to need a multi pin adapter AND female to female (2 female ends ) capability to match up all the wrong plug and hole sizes just male to female wont work is that correct? So why are most universal adapters just one way, i.e. male to female only?

Thanks guys !

Are the panels connected to anything between them and your laptop?

This is the laptop

no?, the solar panel has these fundamental wires with 2 plus and minus inserts into the solar panel and 4 different types of plugs for whatever it charges, the problem was that of the 4 plugs supplied none of them fit my laptop, and they are hard fixed into the fundamental plus and minus connecting wires

if you guys could give me a link to an amazon product that would work for me that would be awesome

Can you describe how you plan to use this total system? Camping? Are you transporting in a vehicle or in a semi fixed location?

Knowing how you use will help come up with options.

Seems the better option, if it fits your use, would be to charge a battery source that can power other devices, like phones.

My idea as a "noob" is to buy this, is that going to fail or will it work but just have a chance of blowing up my laptop?

Just plain camping on the floor no 4x4. Fixed location.

So no lugging about. Once setup, fairly static?

You can try an adapter kit like that, but I am struggling with the wisdom of connecting the panels directly to the laptop charging port. Seems you need a charge controller/power bank type device in the middle (like the Amazon link shows in the images).

Your solar panel is designed to be connected to a "power station" not directly to a laptop and at 5.3kg, it's not exactly light weight.

From what I can see, these power stations contain batteries and their own regulator circuits, to cope with the wide range of voltages generated by a solar panel.

In full sunlight, your panel provides a claimed output of 200W at 23.6V DC (see below).

"The high quality MC4 output connector offers the highest output power in the industry of 23.6V and 200W. "

I cannot see any sign of a voltage regulator module built into your panels, so you'll get a wide range of voltages on the output leads, depending on available sunlight.

Laptops need a fixed DC supply voltage, typically 18.5V for old-style laptops like your Compaq or USB-C PD for modern laptops, e.g. 20V @ 3.25A (65W) or 20V @ 5A (100W).

This is what I would have considered for one of my newer laptops.

This panel comes with a regulator which provides USB-C PD (Power Delivery) of 20V at 3.25A (65W) which would suit my smaller laptop. It's a much lighter solution and easier to carry, but not compatible with your Compaq.

My idea as a "noob" is to buy this, is that going to fail or will it work but just have a chance of blowing up my laptop?

This option will not work. You need a voltage regulator module to generate a fixed voltage output of 18.5V from the panel's wide ranging output voltage.

In weak sunlight or cloudy weather, your panel might output 9 to 12V DC. In reasonably bright conditions, 15 to 18V. In full sunlight, 20 to 24V.

If you connect 24V to your laptop, it might go bang. The CQ70 needs a fixed 18.5V at up to 3.5A. Feed it with significantly less than 18V and the laptop will not charge its battery. Really low voltages might kill the laptop.

You could spend more money and buy a Power Station such as this unit with a DC5521 connector that suits one of your solar panel's four output leads.

It's not an ideal solution, but would provide power when the sun goes down.

The power station has a cigarette lighter DC output socket rated at 9 to 12.6V @ 10A. This should be enough to feed a third item, namely a 12V to 18.5V DC-DC converter suitable for your Compaq laptop:

It's a messy heavy solution, but workable. I just hope you don't have to lug this kit
too far to the camp site with a tent, sleeping bag and stove.

If you're camping with a car or a motor bike as I do, all you need is the 12V to 18.5V converter.

This little kit actually worked only thanks to the female plug being the same as the solar panels, otherwise id of have to have bought a female adaptor kit for the bigger nob.

Thanks for all the help, Chums!

Understood. Good news. Have fun!
