30000mAh Power bank Review! (USAMS 65W)

[@kostime6780]

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

[@striesDIY]

The 20K might not be able to fully charge a laptop, but this one is possible ;)

[@Kodecco]

Awesome detailed review, keep up the great work!

[@matankabalo]

I really liked that you test the capacity and other things. much appriciated!

[@neetchan6631]

Very very detail explanation, Love this video. This person needs to be highly appreciated for his dedication 👍👍

[@TheUltraDavDav]

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!

[@nevarwilliams1445]

Thank alot..need more people like u... I just subscribed 😊

[@cnn612147]

Mine has an error issue when you push the button it cannot be off until the battery drain out and it took several out with several gadgets to clear it out. Do you know what is happened with mine?

[@luispordeus8341]

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

[@striesDIY]

No probs, charging time would take longer

[@solographypixelcreation]

Which Power Adopter Would Be The Best To Fast Charge The Power Bank??? I Tried So Many Fast Charging Power Adopters But It Took 4-5 minutes to Increase 1% of Charge on Power Bank. So, please suggest me the best Power Adopter to Charge Fast...😢🤦‍♂️🙏

[@striesDIY]

You have to look for chargers that support PD 2.0, 3.0 protocol for fast charging and voltage switching. A regular 5V 2A power supply will take 10 hours to fully charge, but a PD 3.0 with 45W will only take 3 hours lesser to charge :)

[@Yeasir.AraFath]

what a review 🎉 Did you tired Baseus Amblight 65w 30,000mAh? Do you recommend Basues Amblight 65w or Usams 65w?

[@striesDIY]

Baseus Amblight is made of plastic case, whereas the USAMS 65W 30000 mAh is made of aluminium alloy casing, which is more durable. On the other hand, if you prefer to charge many devices simultaneously, the Amblight would be a better option as it has more output ports than the USAMS

[@Yeasir.AraFath]

@@striesDIY ok

[@dhaifanakbar6944]

Very nice ti explain haha

[@striesDIY]

Thanks

[@cendlam]

Even though the laptop battery is 5200mAh, why can a 30000mAh power bank only charge it once? Isn't that quite strange?

[@striesDIY]

@@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.

[@G82S58]

I have the same, but how can I charge it again its come with it only type C wire!!!

[@striesDIY]

You can connect it to a type c output charger

[@tungtrai756]

Does it work well? Thanks ❤

[@fardinahommad]

Hello,is it work nicely ? I wanna buy from Bangladesh?

[@striesDIY]

Yup it’s one of the high-quality power bank builds you can find 😊

[@tiendang6790]

Can this power bank be put in carry on luggage in international flight

[@striesDIY]

@@tiendang6790 No unfortunately, Airlines typically only allow 100 Wh max power bank on flight. But this has 111 Wh, so it exceeds the limit

[@guilhermeferrerdesouza6618]

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%

[@striesDIY]

The most accurate way is to directly measure the capacity of the lithium ion battery

[@striesDIY]

But this power bank battery is very hard to remove, and also dangerous

[@fardinahommad]

Does it hurt iPhone 15 battery health ?

[@striesDIY]

@@fardinahommad No, it doesn’t

[@cendlam]

Can I charge the laptop while using it? Some power banks only charge when the laptop is off.

[@striesDIY]

Yes you can. But when using laptop charging is slow because most uses only 65W Type-C

[@cnn612147]

5:01

[@ruriabrandao]

I got this one today to use in Rog Ally and also charge camera and drone batteries Hopefully it will work for years haha

[@nguyendosia1510]

Everything its ok sir for rog

[@tungtrai756]

Does it work well for rog ally turbo 30w ? Thanks

[@leonchris2016]

So we get real capacity around 21.300mAh? Am i wrong bro? If thats the real capacity then i will gladly buy it

[@striesDIY]

Assuming 80% efficiency of the 65W output, the real capacity is near the field of ~26700 mAh

[@leonchris2016]

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

Does it work well?

[@striesDIY]

Still works up till today :)

[@mamlukavlogs6353]

How is the battery ? I would like to buy it

[@striesDIY]

Still working great, meets its 18000 mAh @5V 3A rating

[@mamlukavlogs6353]

@@striesDIY thank you I will buy this

[@itsmebeyonder]

Excellent reviews indeed. Can we get a 6 months later update? Thank you in advance!

[@striesDIY]

It’s actually almost closing in to 1 year now

[@xaviont5673]

could u kindly add a link to the product in the description? i might get one haha

[@striesDIY]

It was added, thank you!

[@pmpduo3760]

Hello is it still working?

[@striesDIY]

Still working nicely :)

[@jaassil]

are u from vietnam?

[@striesDIY]

Not really, I’m from Singapore

[@AgusSalim-zt6qe]

😢😢

[@FPRuzius]

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.

[@striesDIY]

It’s quite common for power banks BMS to fail over time as they have to handle large current cycles

[@FPRuzius]

@@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.

[@FPRuzius]

@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.

[@FPRuzius]

@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.
