among those brands, remax, Pineng ,....etc
which one is better to use ?
my Rxmxx bought fr Shopeemall quite useless.
how much power is needed ?
Those premium brand like Anker,its too pricey for me.
You get what you pay for.
I just got a new Anker 26500mah 165W last 10.10 sale. Got it because no choice, travelling to china need a CCC powerbank.
Previously been using a few 45W 20kmah Xiaomi ones (black colour), that were very reliable and lasted for many years (still have them and they are ALL still working, some over 5 years old). They are actually not bad for the price now, can find for around 80, less than half what I paid for them when they first introduced.
Those more expensive high capacity, high discharge powerbanks quite likely have better cells, likely 21700 instead of the cheaper 18650 which is why they are expensive and come with extra stuff you dont really need like "smart" digital display, built in cable, etc.
If these high end ones are a bit too pricey, just stick to more established brands' lower range offerings. Anker, Ugreen, Xiaomi have been good to me (maybe cuktech also). Those mega wattage ones only make sense if you intend to power your laptop and phone at the same time. If its just your phone, even my 5 year old Xiaomi 45W is more than enough (it will also power my laptop at 45W, but only 1 device), at 1/4 the price of my Anker
As for max output ratings, take it with a grain of salt. The premium ones will let you know exactly which port and how many devices can share the max output. My Anker for example says 165W max, but single line output is only 130W. Other cheaper powerbank will only list total output and sometimes single line output will max out at a rather low 20-30W only.
And as for the max capacity, you are usually going to get like 70-80% of the advertised capacity only. Better brands will list actual usable capacity. My Xiaomi 20K for example, lists usable capacity at around 13k mah only.
