that math at the end tho. no one asked and yet you were a god sent. thank you. all around excellent review! mine arived in one month and it's really good!
@@cendlam Interesting question, yes you are right about the lower capacity but it has a higher nominal voltage of 15.36V, thus it has a high energy of 75 Wh. People do sometimes get confused with mAh and mWh. mAh is the amount of current a battery can provide in 1 hour. mWh is the energy a battery can provide in 1 hour. Energy that goes out to the power bank is the same as the energy that goes in to the laptop, taking away losses in conversion. The power bank nominal capacity is 30000 mAh, but it has a lower voltage of only 3.7V, thus its capacity in Watt hours is 111 Wh. Take 111 and divide by 75 you will get around 1.48 times of charging.
Would there be problems if I charged this power bank with a power supply of 45W or less? I'm from Brazil and the 65w power supply is a bit expensive by the standards here, besides I just bought this power bank
Nice review, thanks for that. But the nominal capacity of 111 Wh may not be the real capacity. To measure so, without the losses of charging a device with the power bank, you should measure the charging of the power bank from ~0% to 100%
Wow, that's dope! Anyway, are u still using that powerbank? Did the batteries capacity degrade? If so, how much? Sorry for asking too many question, im afraid of getting scammed😢😢@@striesDIY
@@striesDIY Then it's still a bad product. If it is advertised to work with high current it should not fail because I used it as intended. I have other powerbanks that still work after 6 years.
@aidartales I bought it to use with the Nintendo Switch, wicht has pretty high power requirements (while playing). I bought my powerbank not long after the Switch came out.
It's a good detailed review. Baseus is more expensive and even if the real cap is 25A, it is a better choice than 20A baseus version
The 20K might not be able to fully charge a laptop, but this one is possible ;)
Awesome detailed review, keep up the great work!
I really liked that you test the capacity and other things. much appriciated!
Very very detail explanation, Love this video. This person needs to be highly appreciated for his dedication 👍👍
what a review 🎉
Did you tired Baseus Amblight 65w 30,000mAh?
Do you recommend Basues Amblight 65w or Usams 65w?

Thank alot..need more people like u... I just subscribed 😊
Even though the laptop battery is 5200mAh, why can a 30000mAh power bank only charge it once? Isn't that quite strange?

No probs, charging time would take longer
Can I charge the laptop while using it? Some power banks only charge when the laptop is off.
Nice review, thanks for that. But the nominal capacity of 111 Wh may not be the real capacity. To measure so, without the losses of charging a device with the power bank, you should measure the charging of the power bank from ~0% to 100%
The most accurate way is to directly measure the capacity of the lithium ion battery
But this power bank battery is very hard to remove, and also dangerous
Very nice ti explain haha
Thanks
Does it work well? Thanks ❤
I have the same, but how can I charge it again its come with it only type C wire!!!
You can connect it to a type c output charger
So we get real capacity around 21.300mAh? Am i wrong bro? If thats the real capacity then i will gladly buy it
Assuming 80% efficiency of the 65W output, the real capacity is near the field of ~26700 mAh
Wow, that's dope! Anyway, are u still using that powerbank? Did the batteries capacity degrade? If so, how much? Sorry for asking too many question, im afraid of getting scammed😢😢@@striesDIY
Z@@striesDIY
could u kindly add a link to the product in the description? i might get one haha
It was added, thank you!
I got this one today to use in Rog Ally and also charge camera and drone batteries
Hopefully it will work for years haha
Everything its ok sir for rog
Does it work well for rog ally turbo 30w ? Thanks
Does it work well?
Still works up till today :)
Excellent reviews indeed. Can we get a 6 months later update? Thank you in advance!
It’s actually almost closing in to 1 year now
How is the battery ? I would like to buy it
Still working great, meets its 18000 mAh @5V 3A rating
@@striesDIY thank you I will buy this
are u from vietnam?
Not really, I’m from Singapore
Hello is it still working?
Still working nicely :)
I got one a year ago. It is dead now. The BMS in this thing is a joke. The overdischarge protection is not working. I don't reccoment buying.
It’s quite common for power banks BMS to fail over time as they have to handle large current cycles

@aidartales RAVpower 26.800 mAh powerbank. The model I have I so longer for sale, I tried looking for it because I would love to have a second one.
