Romoss PMT60 Powerbank Teardown, confirmed with LFP batteries

Romoss PMT60 Powerbank Teardown, confirmed with LFP batteries
This 60000mAh powerbank contains 4 pieces of 48Ah LFP batteries

With its sub $100 price here in my country, it is an excellent purchase considering that it uses LifePO4 batteries. Even better than the Anker 548 which is only limited to 65W max output and double the price. Thanks for this video!

got it for $51 from sale price

Thank you for confirming that it is LiFePO4! I am considering getting one to use as UPS for networking equipment.

Great job. 👍🏻 Thanks!

Your instructions made it much easier for me to disassemble my power bank. Thank you. Unfortunately, my pmt60 broke down after a month and a half of operation. The upper board had a short circuit between b+ and b--. I haven't checked all the elements yet. It is difficult to do this without a scheme. If anyone has a schematic diagram, please share. Found three shorted MOSFETs ETBC015H30. But I don't know what to replace them with, because the marking on them is probably some kind of internal one from the manufacturer. It is impossible to find the datasheet and I still don't know what to put in their place. Other MOSFETs that work as a driver also have a marking G3056 for which I did not find any datasheet.

[@HouseAndSolarProjects]

Sorry to hear. In my opinion, it would be difficult to find the replacement parts. If the balancer part is still good then you can attach the 140w PD modules from Ali to it.

Did I understand correctly that the 100 W limitation is due to the batteries? It is impossible to get more amperes because of the batteries installed in this power bank and everything comes down to this? Is it possible to get 140 W with this board if there were other batteries that allow you to get more amperes at the output? Thank you. You are the only one who took it apart on all of KZbin.

[@HouseAndSolarProjects]

No, it not only due to the number of batteries. The Powerbank in my opinion utilises the Chip in 100W configuration. Unfortunately i don't have access to the datasheet.

Когда заряд паурбана показывает 30 процентов то выдавать он начинает 65 ватт? это правда?​@@HouseAndSolarProjects

[@Роги-п4у]

​@@HouseAndSolarProjectsкогда 30 процентов заряда на паурбанке,то он заряжает в 65 ватт?

[@HouseAndSolarProjects]

​@@Роги-п4у yes, it charges at 65w till 0%

[@silverssonyoutube8438]

I never seen batteries that big before . I thought it had 18650 inside . Do you think this is a quality product made by them ?

[@HouseAndSolarProjects]

Yes, it is value for money, since these batteries have a life of 3000 cycle compared to 1000 cycles for LiPo one's.

[@mennopieters3512]

Thnx for the teardown hope it still works maybe you can try to make it somewhat more waterproof then it was with rubber seals also can see now why they cant do 100 watt over the usb a porta

[@HouseAndSolarProjects]

Yes, it still works. The Chipset does not supports the 100w USB A Prtotocols

[@seffes5994]

Подскажите, какое количество зелёных аккумуляторов внутри? 2 штуки или 4?

[@HouseAndSolarProjects]

Four in series.

[@filipinovines]

how many hours if we going to use 100w?

[@HouseAndSolarProjects]

Around 1.5 hours

[@jokerbest3020]

The manufacturer claims that USB-C supports charging at 100W. I watched other videos testing this device, reviewers confirmed the presence of 100W of power at the connector. Why do you claim the opposite? I'd like to hear your opinion, thank you.

[@HouseAndSolarProjects]

Hmm, I said that the chipset supports upto 140W, here it supports 100W. The manufacturer specifications are correct.

[@jokerbest3020]

@@HouseAndSolarProjects Sorry, I misunderstood, my mistake. After watching the video to the end, everything fell into place. I wonder if it is possible to get 140W with USB-K if the chip supports it. If yes, then how? It would be interesting to hear your opinion. Thanks for the review, only you took it apart and showed the batteries.

[@jokerbest3020]

@@HouseAndSolarProjects so do you know? Is it possible to get 140W from this power bank? from USB-C connector

[@HouseAndSolarProjects]

​@@jokerbest3020unfortunately no, I do not have acces to tools required to do it.

[@Daorson91]

Thanks! Would you recommend this product?

[@HouseAndSolarProjects]

Yes, definitely

[@Daorson91]

Thanks! Ordered both the 40 and 60mah versions. Keep up the good work.​@@HouseAndSolarProjects
