Please Help, How Can I Use This Mini Solar Panel by Weirdberg1: 4:30pm On Feb 02
Hi guys, I need help setting up this mini solar panel. I got it with the intention of using it to charge my phone and power Bank. But the panel has no usb port. Instead, it comes with a 5.5x 2.1 mm DC plug hole like in the picture below.
I have no experience using solar panels.
Does anyone have an idea on how to use it?

it is an 18 volts, 15 watt panel.

You need a dc to dc converter with it, you can buy from jumia.
But I'll advise to get a small battery with it, maybe 12v 18ah, or 12v 12ah.
You'll enjoy it with your phone for years

There are some dc converters that converts directly to 5v from solar panels too.

can you recommend one from jumia? along with a small battery. I did a search for dc to dc converter on jumia and got confused.

18v 15w panel is for charging a 12v battery.
You will need a 12v inverter. Most of the small inverters comes with lights/radio and multiple 5v usb ports for phone charging.
The smallest ones are about 13k on jumia and comes with solar panel similar to yours.
You could sell your panel and buy the complete set. (I haven't seen the inverter sometimes called solar lights being sold separately)

Thanks.
I found this after doing a search on jumia. Can I get that one?
if not, can you recommend one?...am asking because I have zero knowledge on stuff like this hence want to make sure I am getting the right device.

NO!
That inverter was made for cars.
It is designed to be fed from a battery and not from an 18v panel.
It doesn't even have a receptacle for you to plug in the solar panel.

This is what the proper complete pack looks like:

The alternative is for you to buy : 12volts battery (60 amps should be about 20k). and inverter of about 100 watts (another 15k)
This should power your phones, lights and even your laptop for minimal time.
OR
Buy a simple low capacity solar phone charger:

so these are all you need plus battery, the converter without usb is for charging your battery.

This is exactly what I want. I can connect the solar panel directly into this converter right? and the plug would fit.
can I use these without a battery? or a battery is Needed.

Well depending on your choice of module, but you can also cut away the solar connector and connect wires directly.

It can work without a battery.
