All this things just to tell us why we shouldnt fall for fake power bank.
Chai op, i give you thumbs up.

Order you 30,000mah power banks from Jumia for only #3000

The best solar panels you can buy will provide 230 watts of power per square metre under direct sunlight



See more on solar panel efficiency here:

http://www.solarpowerrocks.com/solar-basics/how-much-electricity-does-a-solar-panel-produce/



Being very generous, the size of the solar panel on top of this power bank is 7.5cm by 15cm. Multiplying this you get an area of 112.5 square cm. Convert that to square metres and you get 0.01125 Sq metres

Multiplying the area of the powerbanks solar panel by the "premium" power output of 230Watts per square metre; The power output of the powerbanks solar panel is 2.6watts

The standard charging voltage for lithium batteries is 5 volts.. Using the power, voltage, current relationship:

Power= current x voltage

2.6watts=current x 5 volts

Current = 0.52A
Current = 520mA

So charging current from the solar panel (after converting from solar panel voltage to 5v) to the battery is 520mA.

NOT 1A or 1000mA (solar) as stated on the back of the powerbank below

To charge 30000mah:
30000mAh/520mA= 57 hours of full blast sunlight

To charge 4800mAh:
4800mAh/520mA= 9 hours of full blast sunlight

And this is all assuming you have world class solar panels attached to your cheap off the counter powerbank! In reality, you might have to double your charging time for regular grade solar panels of this size

Hello House,

I'm in a dilemma concerning my househelp and Nanny.

I've noticed she has developed a relationship with the neighbours which I'm not comfortable about.

She isn't a live in hand but has been with us for 2 years now.
She is a woman in her early 40s, a Yoruba Christian who stays not too far from my place.

She helps with housechores when we are away at work.
Her job role is to:-

(1) prepare the kids and take them to school every morning.

(2) Return to the house and do housekeep.

(3)Take the kids home after school hours.

(4)Prepare lunch for them and help them with their home work.

Her hours of work is between 7am and 7pm when she resigns to go to her house.

My daughter has told me how they've gone twice to watch TV next door in the home of both neighbours. (Nanny took them there).

Should I be worried about this development or is it part of the growing up phase for the kids?

Seems she isn't challenged enough with the workload and what does she do when she's at the neighbours.

You can get away with murder in Nigeria but not in the United States .

Your fridge is cold? Really? But, be truthful, is this the first time it is happening?

In my home for four years now, it's been two days on and a day off with power supply and even now it has not changed. Why are we pretending that something positively and highly evident is happening?

Change is gradual I agree. But it didn't start now. Our country has been experiencing it in that little amount. To even begin with, if it weren't for the change in policy in the past can we ever have a Buhari as president?
