I’m looking for advise on power bank that can be recharged quickly.
The power bank itself not the devices connected to it.
I have an EasyAcc 26800, which takes 2x 2A input for regarging itself.
That’s 20W input, I’m looking for a (way) faster solution.
And yeah, it would be great if that solution is availble for cheap on AliExpress
(yep I’ve seen the Anker with 27W input)
20000 mAh and up is what I want, but it even crossed my mind to buy 2x 10000 mAh so the combined charging speed (A input) is higher.
Dubbed as the “World’s Fastest Recharging Battery,” the Yakuma 10,000mAh portable battery recharges ten times faster than other power banks on the market. In as fast as 30 minutes, it can pack up enough power to fully juice up your devices multiple times
RC battery + usb adapter?
Or battery from 18v cordless tool with usb charger. Power tool chargers are equipped with fan and batteries have sort of shroud for air circulation, that’s the reason why they can provide 5-6amps charging without overheating.
Probably, power banks with serial connection and spare higher voltage ac-dc charger do exist, but I’ve never heard about them.
But most likely you need a power bank with all cells in series and a proper balancing board for fast charging
Most power banks still got all cells parallel
Found a black Yukuma for e60 and two types of pink for e30
Yep, it’s going to be the next best thing. And before it is a lot of intermediate version I think.
Right now graphene power banks don’t exist because it’s very expensive. The graphene PBs we see now seem to have like 5% mixed in with old style chemistry.
So I wonder how fast pure graphene will be. And… what kind of charger can supply the explosion of energy to fill them
Perhaps, but I don’t care
I wonder how much shorter.
I also wonder if it’s the battery that dies first. My current PB is still good at charging, but 2 out of 4 charging points are physically dead.
The two recharging ports work fine but some cables fall out because the connector is wearing out.
BTW the graphene ones charge fast and have much longer (claimed) life.
What info are you looking for? All I know is what’s on that page, and I don’t know how accurate that is.
Anyway, that 30000mAh power bank has a 65 Watt output and more important in this thread, it recharges itself with 60 Watt, in about 3-4 hours.
I’m done waiting 6+ hours to recharge
Found another one. 20000 mAh, recharges itself, with 60W, in 1.6 hours.
I think the 1.6 hours is overly optimistic comparing with other power banks.
A picture shows it has 8 cells, which works out at 2500 mAh per 18650.
Replacing them with 3500 mAh ones would bump up capacity to 28000 mAh.
I wish there would be empty banks for sale with top notch input/output ports….
They’re 3000 mah in fact I’m using the provided 100w cable plus 120w gan charger. It takes 3.5 hours per fully charge. If I use 65w gan charger it takes 4-4.5 hours!
