Let’s be honest. How many times have you fully charged your “20,000mAh” power bank, plugged in your phone and before you know it, it’s already empty?

Meanwhile, your phone is just sitting at 70–80%. And you’re wondering: “Is my phone battery bad or did I get scammed?”

Let me burst your bubble. You’re not actually getting 20,000mAh.

The Truth Nobody Tells You
That number written on your power bank? It’s not what your phone receives. Not even close.

Most power banks are rated based on their internal battery voltage (usually 3.7V), but your phone charges at about 5V (or more).

What does that mean? Before the power reaches your phone, it goes through conversion. During that process, energy is lost as heat

So What Are You Really Getting?
Let’s break it down: You bought 20,000mAh. After voltage conversion + heat loss
You realistically get around 12,000–14,000mAh usable power. Yes, you lost almost 30–40%.

Why Your Phone Never Charges “As Expected”
Now think about it: Your phone battery = ~5,000mAh. You expect your power bank to charge it 4 times. But in reality? You may only get 2 to 2.5 full charges.

And suddenly: Your power bank “dies fast”. You start blaming your phone Or NEPA (as usual 😄)

The Real Problem
The issue is not always:
• Bad phone battery.
• Fake power bank.
Sometimes it’s simply:
• Misleading capacity expectations.

But Wait, It Gets Worse
Some cheap power banks don’t even deliver the reduced 12,000mAh. Because of:
• Poor internal cells.
• Bad circuit design.
• No proper power regulation.
You might be getting less than half of what was advertised.

So What Should You Do?
Before you buy your next power bank:
• Stop focusing only on mAh.
Pay attention to:
• Output efficiency.
• Build quality.
• Brand reliability.
Because, a “10,000mAh” quality power bank can outperform an f@ke 30,000mAh any day.

Let’s Settle This
Be honest,
How many times does your power bank actually charge your phone?
1–2 times?
2–3 times?
Or exactly as advertised?
Drop your experience. Let’s see who is really getting their money’s worth. 😄

May God deliver Nigeria from the use of powerbank

Great information for people to learn.

I knew this a long time.

A 10,000mah ankers power bank can outperform a 30,000 new age power bank.

Buy the Itel 100,000 mah power go. It can be charged with a solar panel, uses only 10% to power my standing fan from going to bed to waking up. Powers my laptop too, and it costs a little above 100k.

This is the real answer

Most products made for our market are falsely advertised because who is going to test anyway?

What are the factors, ratings, numbers, identifiers to know and measure output efficiency?

Brand quality is a farce, except you buy from source.
Brand reliability is marketing.


Oraimo 20,000mAh failed me.
5000mAh battery, I can only charge fully two times...and that was in the early days of the charger.
Now it only charges full once.

Oraimo una fuckup
