Note on 10:56, It's misleading to compare the battery capacities since the battery voltages are different. In this case it is twice of the phones and the power bank. Sony a6300's battery is at 7.2v nominal (2 x 3.6v in series), while the power bank and phones have 3.7v nominal. This is why batteries should be always compared in Watt-hours, not milliamp-hours. Power bank and phones companies market their stuff in milliamp-hours since the number looks bigger. If we were to compare the batteries in watt hours: Xiaomi Power bank: 3.7v x 30,000mAh = 111Wh Note 20 Ultra: 3.7v x 4,500mAh = 16.65Wh Galaxy S10+ = 3.7v x 4,100mAh = 15.17Wh Note 10+ = 3.7v x 4,300mAh = 15.91Wh Sony a6300 = 7.2v x 1000mAh = 7.2Wh Tab S5e = 3.7v x 7040mAh = 26.05Wh
What surprised me about this test is this power bank is a little over 80% efficient charging battery to battery which is typically a little over 60% with other power banks.
sure it does. I have an older 10000 TP Link, which is far far smaller and light as a feather, so I thought after years we would see improvements in size and weight 😬 now we will see. Have a portable tyre pump from Mi, which is top of class
Brother, can I press the powerbank button twice and switch to slow charge? If so, do I have to press 2 times before the two first connect to each other or after connecting? (I do not know anything about this, that is why I asked the question) Please reply
Recently i purchased 30000 mah mi power bank. In that when i double clik side button normal mode is not working again fast charging only displayed in my phone. Plz reply
Thank you! All that testing is literally the most important part, what annoys me the most is that popular channels on YT do 'Reviews' without even doing any tests, talk specs and that is it! and get thousands of views lol.
Wow. All I can say is you're always very informative. I appreciate your knowledge! I am trying to convert my lithium e bike to sla batteries. Perhaps, you could suggest a path?
@@TechGuyCharlie Bro my plan is to make a backup for my modem via type c connector...so i can charge the powrbank then electricity goes i can utilize the backup of the powerbank without cutting of my modem
i charge it with 25watt samsung charger and it gets full then i forgot to unplug the charger. My question is will it affect my power bank or it is not a issue?
I don't see a reason why not. Your solar inverter must have a USB outlet that should support the Quick Charge standard, or else it will take hours. Or else just plug in a standard 25watt charger into the AC outlet of your solar system.
This is exactly how a good test must be made! You gave all the info which is needed of this product. Thank you.
Very welcome! Glad the video was helpful. 😊
Parabéns! Esse foi o teste mais completo de power bank que já assiti no RUclips! Excelente vídeo!

Fast, precis and enjoyable review. Can't ask for more!
Thank you! 😊
Can u charge the powerbank using Xiaomi 27w charger
In what speed it charge and how long it take
Can you charge with both the type c and micro port at the same time?
nice, well done 👍🏽 what surprises me is that the 30000 bank looks far larger than 3 10000 banks would add up to.
Thank you, and It sort of does!! By the way, this exact same power bank in the video is still running great till this day!
sure it does. I have an older 10000 TP Link, which is far far smaller and light as a feather, so I thought after years we would see improvements in size and weight 😬 now we will see. Have a portable tyre pump from Mi, which is top of class
@@TechGuyCharliedoes it still work properly?
@@shiferawgadile5337 Of course! I still have this power bank and it still works great.
Excellent work buddy!
Thank you!! 😊

If only I had seen this earlier🤣🙈 Great work as always❤️
Oh, you were looking for a power bank, were you not?? 🙈
Recently i purchased 30000 mah mi power bank. In that when i double clik side button normal mode is not working again fast charging only displayed in my phone. Plz reply
I think u pressed it too fast
Great video Charlie. Really enjoyed the extensive testing and charging you did. Great stuff!

@@TechGuyCharlie thats what makes your content very unique. You're putting in so much of an effort. People are bound to notice soon!
Thank you Bro Nice Video from Tunisia 🇹🇳✌️🌹
Thank you so much bro! 😊

Can i charge powerbank using Usb + type c at one time
Thank you for a very thorough review Charlie. The best review on RUclips for this power bank. Definitely worth my thumb up.
Thank you, means a lot! 😊
Very nice complete review
Thank you! 😊
Perfect, thank you for this video.
Deep Explained Well-done..
Thank you!
note 20 ultra how many time charging possible single charge. bro ??
bro is it quick charge work on output port while charging this powerbank with a quick charge charger to socket outlet?
Yes bro, the power bank supports pass through charging, but don't recommend that as it takes even more time to charge the power bank up.
@@TechGuyCharlie Bro my plan is to make a backup for my modem via type c connector...so i can charge the powrbank then electricity goes i can utilize the backup of the powerbank without cutting of my modem
Hey, I'm back, and android 11 just came out for the Samsung galaxy tab s5e, when are you gonna do a video on that, thanks
good effort bro !
Thank you so much 😀
Hi - has this battery got an álways on' function, please? (so it doesn't go to sleep when not power is drawn)
What is your use case that requires an always-on function with a power bank? Don't think I've ever seen such feature.
So overall is it good considering the price?
It is an awesome power bank!! Go for it.
They also announced someone as crazy as this:200W wired charging and 120W wireless charging😱 Also,great review as always😎🤜🤛👍👍
Was reading about it on GSM arena! I love it when these brands come up with new interesting products and tech, very impressive. And thanks bro!
Hi! Does it still work to this day?
It indeed does! I use it almost every other day.
i charge it with 25watt samsung charger and it gets full then i forgot to unplug the charger. My question is will it affect my power bank or it is not a issue?
Don't worry about it, even if you leave it plugged in for weeks nothing will happen, there are overcharge protection mechanisms built-in.
Still recommended to this day??
Yup! I've still got this power bank, and its working perfectly fine.
Can I charge the Xiaomi battery (Power Bank) with a solar system?
I don't see a reason why not. Your solar inverter must have a USB outlet that should support the Quick Charge standard, or else it will take hours. Or else just plug in a standard 25watt charger into the AC outlet of your solar system.
Would this be able to charge laptop? (the laptop will be the only device plugged in)
Nope! This wont charge a USB C laptop, for that you will need a power bank with much higher output like the new mi power bank hypersonic.
Hey, is it ok if I use Xiaomi Mi 45W USB Type-C Power Adapter to charge power bank ?
Of course! You will be fine as long as you use a fast charging charger.
Please make A video about tab s5e android 11 update
I have the Sony srs xb 20, good one boy!!!
Good review👍🏻👍🏻
Thank you! 😊
Can this power bank be charged and charging a device at the same time?
Yes, this power bank does have pass through charging, but then it takes more time to charge this thing up.
great
Thank you!
First view 😀😀
30000 mAh hoooo mey god
Its crazy! Took me over 3 days to discharge and charged over 6 devices.
@@TechGuyCharlie this could probably charge my Note 10 plus up to 6 times...wow!
