How large? Does it need to go on planes? How much output does it need (to charge a laptop or just a phone)? I just bought an INIU Cougar - there are 25ah and a 20ah versions which may be of interest. However they are extremely small and light for the capacity and have high input/output and keep low temps and have high efficiency. Answer from poulan9 on reddit.com

January 25, 2025Best 20,000mah USBC power bank?
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. More on reddit.com

October 10, 2025Help finding a 20,000 mah power bank.
You can carry two 10000’s. That way you eliminate a single point of failure. I use the Nitecore NB10000 which is in the lighter side. FWIW a 10000 will get me through a 4 night trip keeping my phone and InReach charged and I often use my phone frequently for navigation. More on reddit.com

September 10, 2024If I want more battery power (20000 mAh) for my Oculus quest 2, would any powerful power bank work?
Yeah it’ll work, its exactly what I(and many others) do with the quest 1. But IMO a 10000mah one is more than enough, I have never managed to play long enough to drain the quest battery and a 10000mah power bank. More on reddit.com

May 3, 2020How to charge your power bank or portable charger?
Charging a power bank is straightforward. Simply plug the power bank into the charging cable, then connect the cable to a power adapter or USB port on a computer. Wait for some time until the power bank is fully charged. Once complete, disconnect the charging cable, and your power bank is ready to use.

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.

January 25, 2025 -
Hey Guys,
As the title says, I am looking for a reliable, large capacity power bank for travelling, with a good battery life and low self-discharge.
I haven't had much luck with them so far, so decided to reach out to this community.
Please share your thoughts and first hand experience! All and any help is much appreciated! 😎
Update: We would carry it with us on planes. Mostly for phone/tablet and mobile data router charging. Laptop is a plus.

Answer (1 of 2): From a redundancy perspective two is better than one. There will be marginal extra weight to carry around. And a small management overhead in keeping both charged.

Best 20000mah USBC power bank? : r/onebag
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
