Last Updated on September 23, 2021 by Kennedy

Are you planning to buy a new how 20000mah power bank but first trying to know how much power it gets or probably the number of times it going your phone.

I got you properly covered here.

I’m not a technician so I will explain this post based on my research using a 20000mah power bank to charge different phones, and how to long it lasted.

Going straight to the question of the day;

How much power is 20000mah

A 20000mah is very large and can charge a mobile phone 4500mAh for three good times before the battery goes flat. This is to tell you that a 20000mah can last very long though it depends on the brand and the quality of the power bank. 

From my experience, I bought two different 20000mah power bank, and they include the followings;

  1. Anker power bank
  2. Romoss power bank
  3. Rav power

These are the three power banks I bought just to test how powerful, how strong and how much power is 20000mah power bank.

Remember, I’m not a technician so this post will be explained in a lay man’s understanding.

How much power is 20000mah power bank

A 20000mah power bank can last for the entire day before it drains out though everything depends on the battery capacity of a given phone, and the quality of the power bank.

Why did I stress everything also depends on the quality of the power bank?

This is because you will see a power bank of 20000mah but it can’t charge a mobile phone of 3500mah battery capacity for up to two times. Only a single charge the power bank goes flat.

The truth here is that there are lots of fake power bank out there in the market so you need to very wise while making a selection or buying a power bank. Don’t get enticed seeing 20000mah because it may be just 10,000mah in disguise.

Now let’s proceed to the how much power is 20000mah based on my experience with the three mentioned power banks.

1. Anker Power bank

how much power is 20000mah

I bought this very Anker PowerCore Essential power bank for this test and I must admit that I was really impressed with the outcome or the test result.

I used the Anker PowerCore Essential power bank to charge the Samsung Galaxy S21 Ultra which has a battery capacity of 5000mah, the Samsung Galaxy s9 plus with a battery capacity of 3500mah, and the iPhone 11 pro max with a battery capacity of 3969mAh.

This was the outcome and which answers the question of how much power is 20000mah.

The anker power bank was fully charged, and I purposely drained the battery of the Samsung Galaxy S21 Ultra to 15% for this test.

The Anker PowerCore Essential 20000mah power bank charged the galaxy s21 ultra from 15% to 100% for a good three times and still had a charge. On the fourth charge, I was able to get the Anker PowerCore Essential power bank to charge the phone from 15% to 33% before the battery drained out.

Using Anker PowerCore Essential to charge samsung galaxy s9 plus

As the Samsung Galaxy s9 plus battery capacity is 3500mah, I was able to get five full charges using the Anker PowerCore Essential before the battery goes flat.

The fifth charge wasn’t fully charged but at least it was able to reach 65% before the battery goes flat.

This means that the Anker PowerCore Essential power bank has so much power for a phone with a battery capacity of 3500mah.

Asking how much power is 20000mah power bank for such a phone, I will say really suberb and very strong especially if you bought a good quality power bank.

The iPhone pro max has a battery capacity of 3969mAh and it quite very strong i must say because the Anker PowerCore Essential power bank charged the phone from 15% to 100% for three good times, as the fourth charge wasn’t full before the battery drains out.

So if you have the iPhone 11 pro max phone be rest assured that the Anker PowerCore Essential 20000mah power bank will charge your phone for a good three and half time before the power bank goes flat.

The 20000mah Romoss power bank charged my galaxy s21 ultra for almost four good times.

The first three charges was from 15% to 100%, while the fourth charge was 15% to 73% which beats the Anker PowerCore Essential power bank charge of 15% to 33% on the fourth charge.

This tells you how strong the Romoss power is, and asking how much power is 20000mah for Romoss, I will say it is a powerful one, you will never regret buying the power bank.

Ask no further because the Romoss 20000mAh power bank charged samsung galaxy s9 plus for a good six times before the battery went flat. And I’m very much sure that it will charge any phone of such battery capacity for a good six times.

I was really really impressed because I didn’t get such while using the Anker PowerCore Essential to charge my galaxy s9 plus.

Using Romoss power bank to charge iphone 11 pro max

For the iPhone 11 pro max, the Romoss 20000mAh power bank was able to fully charge the phone for a good five times or almost five times as the last charge wasn’t fully charged.

This implies that the power bank will serve any iphone user better including the iphone 12 pro max.

3. Ravepower power bank

This is another suber quality power bank though I prefer the likes of anker and Romoss to it, but there are quite number of persons that prefers the ravepower power bank to anker or any other power bank.

For this experiment of how much power is 20000mah power bank, the race power didn’t disappoint me either and it was really strong.

So below was my experience using the rave power bank to charge my samsung galaxy s21 ultra, s9 plus and the iPhone 11 Pro Max.

Just like the Anker PowerCore Essential, the experience with rave power bank was just the same with the Anker PowerCore Essential power bank.

I was able to get a fully the Samsung Galaxy S21 Ultra fully charged for three good times and the fourth charge didn’t reach 40% and the race power battery went flat.

With a phone like the s9 plus or battery similar to the phone, you will get your phone fully charged for four and half times. It isn’t bad either but the romoss power bank did a great job compared to the rave power.

Using the rave power bank of 20000mah capacity, I was charged the iphone 11 pro max for a good four times and the battey went flat.

I wasn’t able to get a half charge though the three full charges are very good compared to power banks I have used previously to charge my phones.

How many times can a 20000mAh power bank charge an Android phone?

It depends on the battery capacity of the android phone but be rest assured that a 20000mAh power bank will charge an android phone for at least three times before it goes flat.

It your android phone has a battery capacity of 3000mah or 3500mah, a good quality power bank can charge the phone for four good times. Four good times means from 15% to 100%and before the battery goes flat.

I’ve already recommended Anker PowerCore Essential, romoss and ravepower power bank as one of the best 20000mah power bank you can buy today.

This is based on my own experience.

20000mah power bank will always be way ahead and better than 10000mAh power bank in terms of size and capacity.

A 20000mAh power bank can last for a whole day or two depending on the user’s usage as it can even go for three days before the battery drains out.

However, the Romoss 20000mah power bank only last for two days using it to charge my samsung galaxy s21 ultra.
