Cannot find much user experience about Romoss, particularly the Polymos series. I have a Xiaomi 10400. Looking to get another powerbank and considering Romoss Polymos 10000. Anyone bought before? Seeking if any direct comparison experience, or just of Romoss (Polymos) itself in terms of real life capacity impression. There is a guy who mentioned Polymos, but does not sound genuine.

I used both and can say both are good. Currently using XiaoMi 5000mAh for its slim size.

Thanks for all the feedback! Indeed size has now become a factor, when previously i thot i didn't care. wwenze, regarding losing its charge, that's a concern and one way of comparing. But i haven't really go about testing the Xiaomi. Need time to really test the capacity one time, and then after that whether it loses the capacity. Cos they claim 93% efficiency. Have you done some tests? I hope to find a good way to check also, cos I like to test things like this.

Test? I just leave it for 2 months and the charge is empty when I needed to use it.

The one thing about true capacity is that 2A usb chargers take a darn long time to charge my romoss 10400mah powerbank. Dont think there are any powerbanks that can safely accept anything higher then 2.1A input other then those classic AC charger powerbanks.

For XiaoMi 10400mAh power bank, 2A charger takes 5.5 hrs while 1A charger takes 10hrs.

Tough luck for those who are in office in morning but out by lunch. Not many will dare leave the device overnight charging in office.

Haven't tried Romoss before but have Xiaomi 5000mah. Maybe because it's a different type of battery compared to the cylindrical type, i realise it loses capacity faster. I have an anker 2nd gen astro 12,800 mah as well, and it seems to retain capacity better.
