Is the PCB available in the market? Would like to DIY mine with at least 2 additional parallel batteries.

[@DooMMasteR]

Can you check if this power bank supports passthrough (input+charging while using an output)? The design could allow for it since USB-C1 and (USB-C2 and USB-A) are split. This check would also be a nice addition to the general device capabilities introduction at the beginning :-)

[@VladStefanXPopa]

Probably does support pass through. Because has 2 different chips for each usb c. The only problem is the capacity probably is 37wh at 30w output... i had something similar and was disappointing

[@VladStefanXPopa]

@DooMMasteR If you look at the rated capacity is 11000 at 5v. While others are 12000 or 13000... so this powerbank has less capacity

[@VladStefanXPopa]

Plus at 100w these cells output almost 7 amps continuous because there is no parallel there are only 4 in series.. thus i think greatly reduces the lifespan

[@DooMMasteR]

@@VladStefanXPopa I mean the cells are rated for 1C continuous only so yeah, quite some overdrive. But true the DC-DC efficiency of the UCB-C2+USB-A part at 5V is very disappointing.

[@heyholetsg0]

​@@VladStefanXPopaHi, you sounds knowledgeable about powerbank, can you help recommend me a good properly rated powerbank with a good lifespan?

[@fishersam1464]

Can you tell me the price of this power bank please?

[@wildeden7216]

59$

[@julianst28]

This Powerbank supports Xiaomi 120W Hypercharge

[@Datvi]

If 4 li ion 5000mah batteries connected in series you cannot get 20000mah, its still 5000mah only voltages are added not the capacity.

[@DooMMasteR]

it is very common to only advertise total 1S capacity, regardless of the configuration, it is at least somewhat comparable, but Watthours are what counts.

[@DarkZerol]

The name of the brand is "CukTech"? Seriously? 😂

[@EWWP10]

the cuk represents the recognition of the Čuk circuit, a special type of DC-DC circuit topology proposed by Slobodan Čuk in 1976.
