Power bank that can be recharged fast.

Sorry for my typo. They are 30000 mah. I purchase white & black each 1.

Charges: 120W https://www.aliexpress.com/item/4001218252042.html?spm=a2g0s.9042311.0.0.27424c4dhtmdVF
65W https://www.aliexpress.com/item/4000237954145.html?spm=a2g0s.9042311.0.0.27424c4dhtmdVF
If you are not rush try to wait until 11.11. Prices may drop tremendously.

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.

Even found a 150w charger. https://www.aliexpress.com/item/1005001411198892.html?spm=a2g0o.productlist.0.0.71725cd0D6P1IW&algo_pvid=eaf3fdbd-41f4-47db-8d32-f3af66def6d6&algo_expid=eaf3fdbd-41f4-47db-8d32-f3af66def6d6-0&btsid=0b0a182b16018366972544030eda20&ws_ab_test=searchweb0_0,searchweb201602*,searchweb201603*

I use 65w charger more than 120 & maybe I was using more than 2 outputs!

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 fastest way to reload your power bank is to swap in freshly recharged cells, and put the depleted cells on a charger for next time.

45w input.

60w input.

True, but I ran into a few problems with that (as an owner of both XTARs)

- Not so compact. (needs a seperate charger for speedy recharging.

- Not the latest PD or QC support.

  • I’m looking at the 20000+ mAh range. That’s 8 cells or more. That’s getting close to the price of a PB for just the cells.

As a matter of fact I’m already following your suggestion.
4x 10000 mAh PB
1x 26000 mAh PB
8x 18650
1x 26650
1x 21700
1x 20700

The 20000 Xiaomi isn’t the fastest I’ve found but, it’s the fastest known brand.
The 10000 Xiaomi specs are vague. They recommend a 30W charger, but in the picture just below that they say 18W. 18W is very common for this capacity, 30W would be great.
Here it says 18w/4 hours. https://www.aliexpress.com/item/32974071402.html?spm=a2g0o.productlist.0.0.75aee602CiVtLD&algo_pvid=70a3663c-eef7-44ed-92b6-60afe106d319&algo_expid=70a3663c-eef7-44ed-92b6-60afe106d319-1&btsid=0b0a050116018795213606373ea3ef&ws_ab_test=searchweb0_0,searchweb201602*,searchweb201603*

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 :slight_smile:
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.

That’s about the capacity of a regular 10000 mAh power bank.
Looks bulky, how does it recharge?

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.

not necessarily, if temperature limits are kept.

(might require fans for really fast charging)

you can charge to 80% as fast as you can remove the heat, basically.

My take on fast charging. I’m sure someone will kick my butt if I’m talking nonsense…… :slight_smile:

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.

Is TOPK a good PB brand?

Hey there,

I have found an article about the Powerbanks that charge fast. They all have 10000 mAh, so thats pretty nice. Anyhow, hope I was helpful: Powerbank 10000mAh: Test & Empfehlungen - TECHNIKHIWI

Cheers!

Same here about those empty power banks. I found this one recently Page Not Found - Aliexpress.com (24000mAh with DC jack/type c in/out and USB A/C out) and asked the seller if I could get it without batteries inside because of the cheap price. He told me first off they don’t offer support for that but I assured it that was no problem, and afterwards he got back to me with a price quote of about $220. Still way more than I hoped but hopefully there will be more versions like this in the future!

@Frescon
Very steep price… but the charging speed is absolutely great.
It’s not clear what’s DIY about this PB. Nowhere I see I can quickly swap cells.
I’m gonna skip this one because of the section highlighted in red.

Same feeling about the price and capabilities, I hope there will follow other devices like this but with a lower price. Yeah the “DIY” part is probably to attract people to the listing. Cells can’t indeed be quickly swapped, you have to create the battery-pack yourselve using a spot welder (in the case of the PCB/enclosure only quote).

Ah yes good catch I didn’t even notice that…

That looks like the YZX Studio Terminator 11…

There’s some more description & pictures from their Taobao store (use Google Translate):

Oh nice thanks for linking to the Taobao shop! It’s pretty sad they don’t have a dedicated AliExpress store because they have a lot of cool (but expensive) stuff :confused:
