Just a friendly reminder to everyone that many countries don't allow you to fly with power banks over 100-160wh in your cabin bag (and power banks can never go in a checked bag). Some countries (like Turkey and India) can be quite strict about it. Answer from thekindwillinherit on reddit.com

Embrace Unlimited Power With 20000mAh Power Bank - Anker US
A 20,000mAh power bank offers enough capacity to charge a wide range of devices multiple times. For example, it can typically charge most smartphones 4–6 times, provide 1–2 full charges for tablets, and power up smaller accessories like wireless earbuds or smartwatches dozens of times.

20,000 mAh Power Bank recommendations? - USB Power Devices - BudgetLightForum.com
Looking for something with QC3.0 output that is known to use quality cells and delivers the advertised capacity. I know HKJ favorably reviewed the Ravpower one. It is currently $45 on Amazon. I’m just wondering what else is out there worth considering, hopefully under $40. More on budgetlightforum.com

Should I swap this 20000 mAh power bank for the 27000 mAh version instead?
Depends on your use case. Do you need the extra capacity? Would the extra weight be an issue? More on reddit.com

Anker Prime Power Bank 20,000mAh Mini Review
Welcome to power banks numbering. This bank has 20000 mAh at 3.6V input, so at 5V output it's only rated at 20000/5*3.6 = 14400mAh. 80% of your battery is 3481mAh. If this took 33% of the bank, then its' effective capacity is only 10548mAh, meaning charging efficiency is only 10548/14400 = 73%. This is below average for a power bank (typically the good ones have around 80-85% efficiency). Though, as this is only first charge there maybe shenanigans with the bank's report feature and it's actually not that bad. More on reddit.com

Is 20000mAh power bank enough?
This depends on your actual need. Generally speaking, a 20,000mAh power bank is generally considered sufficient for most people's everyday charging needs. However, if you have power-hungry devices or plan to charge multiple gadgets simultaneously, preparing a higher-capacity power bank like the 24000mAh Anker 737 Power Bank (PowerCore 24K) or wired chargers for Samsung or other phones might be more suitable.

Is a 20000mAh power bank better than 10000mAh?
Whether a 20,000mAh power bank is better than a 10,000mAh one depends on individual needs and preferences. A 20000mAh power bank can store more energy but are also heavier and bulkier than a 10000mAh power bank. So, if you prioritize portability, a 10000mAh power bank is ideal. But if you prioritize capacity, a 20000mAh power bank is the better choice.

How long does a 20000mAh power bank last?
How long a 20,000mAh power bank lasts depends on the battery capacity of the device being charged and the frequency of charging. In general, a 20000mAh power bank can provide 4-6 charges for an average smartphone. This would imply a duration of 4-6 days if you charge your phone daily using the power bank.

r/onebag on Reddit: Best 20,000mah USBC power bank?
October 10, 2025 -

Hey everyone, thanks in advance for any discussion and help. I appreciate it a lot

I’m coming from the anker at 325 (20,000mah which has 2 USBA, and 1 micro + 1 usbc In only to charge)

Since my new devices are all the USB-C (AirPod, iPhone etc) I’m looking for a power Bank that maybe has only USBC or maybe one USBA and the rest USBC

I’m leaving to backpack around Asia and Latin America(again) for the next couple years and want something that’s both reliable, and rugged. I recently got the ultra slim anker 5k MagSafe for day trips, but often times I do multi day hikes, or spend extended periods of time in the Amazon rainforest where having that larger capacity is invaluable.

I’m only travelling with my phone and AirPods (not kindle, no laptop etc)

What power banks would you suggest that aren’t wide in thickness like the newer block type ankers 5(akward to fit in my tech pouch). I also don’t want a built in cable

Thanks again!

Edit- I chose the I ended up going Iniu p62-e1. Was exactly what I was looking for
