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!
It’s strange the 100w charger charges faster than the 65w charger, because the power bank input is rated at 60w.
The only reason I can think of, is that the 65w charger delivers less that 60w. Or something goes wrong negotiating the power between the charger and PB.
Or less likely, that the input accepts over 60w.
That’s a good possibility.
Also a bit of problem selecting a good charger.
When I’m at home I don’t really care how many chargers are plugged in.
Right now I’m trying to find a lightweight, and fast option to recharge my stuff between flights.
A laptop takes up to 100 watt, so I was happy when I found the 120w charger you also posted.
It got even better with the 150 watt charger.
But once two outputs are used the max output drops greatly. Even if one port only supplies 1 watt.
The first Anker on the list is bundled with a 60w charger, but I can’t find how many watts the PB actually uses. You wrote 45, but considering it has a 60w charger and the charging time is very comparable to the 60w Baseaus I have high hopes it’s 60w
Pitty it has an Anker price tag, and a charger I don’t need. Nevertheless a great find.
The second Anker has great spec, not so great price, odd capacity.
The third Anker with it’s 213Wh isn’t an option. Bulky and only 100Wh is allowed on board a plane.
with a power tool charger, that is a 20v power tool battery, they come in 1.5, 2 , 3, 4, 5, 6 ,9 AH it takes up 1.5 hour to recharge,
yea it is bulky, if you want something portable look for power bank with usb C plug, regular micro usb can not provide enough current to charge fast, usb c can provide for up to 40 watts at 5v.
My take on fast charging. I’m sure someone will kick my butt if I’m talking nonsense……
Some cells allow for a much higher recharge current as their competition. (Sony IIRC)
A 20,000 mAh PB often contains 8 cells.
Very often charged with 2A because that’s the USB micro limit.
My 26800 mAh PB has 2x 2A in. Still very good after many recharges.
It recharges in about 6 hours with 20 watts.
With 8 cells that 4/8=0.5A cell. I think that can be safely upped a bit. Total 8A perhaps.
I’ve yet to find a charger that does 8A at 5v, but using 20v I’ve seen up to 65watt
And as I wrote earlier: If the PB degrades from fast charging, how much, how fast?
10%/year or 1%/year. Big difference. Plus often I don’t care about speed and I could use a less powerful charger.
But when traveling I often want as fast as possible.
While my PBs cells are still in great shape the ports are not. It’s an EasyAcc, which may not be the top brand, but it’s not junk either.
2 ports can hardly/not be used.
2 ports work with certain cables (looks like the plugs are not 100% the same size)
Point being, while the cells may last another 10 years the ports will be dead long before that.
Plus, even if everything was still in mint shape I would still want to go faster.
There’s just a lot of room for improvement in PBs, size, weight, (re)charging speed, new protocols, etc.
