That Jumia product won't solve it for you. Firstly the usable energy from the battery is around 450wh assuming it's a good brand which is doubtful at that price point. I am not sure the kind of laptop that you have but let's assume it consumes 60W per laptop. Which will result in a total consumption of 180W per laptop.

Regular fans consume around 70W. Rechargeable fans consume around 45W. DC fans consume around 18W. So depending on the type of fan that you have, you could use as little as 18W or as much as 70W.

I don't know the consumption of your speaker. You can check and factor it into the calculation.

When you remove the 180W and the 70W from the battery capacity which is 450Wh, you are left with 200Wh which won't be enough to power them for another hour. Also, the panel is too small to generate enough to power your loads and recharge your battery at the same time.

So that product isn't ideal.

I will suggest two alternatives. Spend more and get value for what you buy.

Get a 200ah lead acid battery for around 160k
A 1.5kva Inverter for around 95k
A powmr charge controller for around 61k
2 300Watts panels for around 91k each or therabout.
Then wires and installation cost.

If budget is an issue, then get

A 60ah 12v lifepo4 battery of around 65k
A 300W panel for around 91k
Charge controller for 61k
Inverter for around 51k

Then manage your consumption very well. You could use only one laptop and buy a DC fans.

Hope this helps.

Pls can we talk on this?
