New ATL thanks to camels. Almost getting to $130 ❤️
For those who are new, this is great for portable gaming devices, a comparable/slightly superior one is the ZMI.

Colonel Mustard, in the Conservatory, with the Anker 737 Power Bank.
Paid sub $132 on Ebay last month
Got this for $132 with an Afterpay promotion on eBay. Absolutely love it. You can recharge real quick too. Takes about an hour with my Belkin GAN charger at home.
I have not been able to achieve the 140 watts it has suggested though.
What are you using that requires 140w? 100w is the highest I have come across. Most cheap power banks struggle with 100w.
I’ve tested in a number of devices, just reporting my observations for anyone who may want that. This is plenty powerful for me.
It's not 140Wh, I explained last time. From Reddit: While 737 is indeed max 140W charging power, it is only 86.4 Wh (or 4000mAh *6 cells = 24000 mAh) capacity, not Watts but, Watt-Hour, so the maximum you'll achieve is is 86w
@King Steuart: I have never seen your article until but this was wonderfully informative.
I wasn’t aware of this.
so the maximum you'll achieve is is 86w
86 Wh ;)
And after efficiency losses you get about 75Wh, which is pretty decent.
After efficiency losses in a device charging from the power bank, you get more like 65Wh in the other battery. (This varies depending on efficient the device is that is charging)
Efficiency is slightly worse at 140W output, so more like 70Wh. Which means it only runs for 30 minutes! (which is also normal and expected)
140W from a single port requires a device that uses 28V, 5A. Some recent laptops (such the MacBook Pro) charge at 28V but most laptops or other devices don't.
You can also charge the Anker 737 at 140W, if you have a 140 (28V, 5A) charger.
You can also get 140W total by using multiple ports. EG, two laptops plugged in via USB-C can both use 20V, and share up to 140W. Or three ports, two USB-C devices can use up to 122W, and one USB-A device can use 18W.
Was thinking of getting this but a decent proportion of the recent Amazon reviews are critical (mostly because the unit does not last long and/or the quoted charge is not achieved) so stayed away
The negative reviews on Amazon are mostly user error, misunderstanding about how it works, or legitimate faults. The number of actual faults seems pretty low.
There are heaps of review that capacity test the 737, but I have as well. It meets the advertised spec, and can output up to 140W just fine. Converting power from a battery, to the voltage required to charge a device incurs losses (mostly as heat). This is normal in every power bank. The exact same thing happens in every device with a battery. The 737 has around an 87% efficiency, which is pretty good.
It is rated for 86.4Wh, and so after efficiency losses, it outputs about 75Wh.
But what many people miss is that any device charging from the power bank also has efficiency losses. EG, when you charge your phone, it heats up. So a a phone might have a 18Wh battery, but requires 21Wh to charge it.
So if charging a device, then you would expect about 65Wh to actually make it into the devices battery. So you might get four phone charges out of it. Or if your laptop has a 90Wh battery, the 737 power bank will only charge it to 72%. This is completely normal, but often people don't take it into account.
What's the difference between legitimate faults and actual faults?
I mean the same thing when I say legitimate faults and actual faults. Just faults with the power bank, rather than user error.
Funnily enough I think the 737 having a screen that tells you the wattage causes misunderstandings for some people. Such as complains about charge speed (EG 12W for a phone or 1W for earbuds) when those are perfectly normal charge speeds for much of the charge cycle.
I suspect some of the rapid self draining complaints come back to tings like people accidentally enabling low current charge mode, or leaving lightning cables plugged in, which can draw a small amount of power and keep the power bank from sleeping.
I have a CY4131PBCHE Cygnett 25k 100W that I am pretty satisfied with, but I like the display information on this Anker.
Can it be trusted as much as a company that sells to bricks and mortar?
The Anker is 635g vs the Cygnett of 499g.
Also worried about the shape as Anker isn't as conventional, more blocky compared to flat shape of the Cygnett that sits nicely in the backpack.
Let me know your thoughts.
The Anker is probably better quality. It has been extensively tested and there are various teardown videos.
There does not appear to be any info on the actual cells used in the Cygnet power bank. It has pretty similar layout and dimensions to the ZMI No.20 and has room for 21700 cells. However quality cells will be ~400 grams alone, and other decent quality power banks with similar capacity and 21700 cells are heavier. The ZMI No.20 is 580 grams.
The Cygnet may just use lighter construction. Or lower quality 21700 cells. Or it may use pouch cells, which are typically lighter than 21700s for the same capacity. Pouch cells can be perfectly fine if high quality, but often don't tend to last as well in heavier use.
I got the Alogic Ark 27k 140w power bank from ebay when the seller had a 20% off sale for $136.70
There is a Alogic Ruck 20k 130w on ebay for $79
https://www.ebay.com.au/itm/256466033923?mkcid=16&mkevt=1&mk…
These might be substantially different in terms of the actual output and sustained output. But it’s entirely possible those are better than the Anker because I don’t know them.
I also place a premium on Amazon vs eBay.
I bought the alogic ruck 20k direct from alogic AU for much more than this advertised ebay price. Both seem to charge at the 90w rate from my belkin Gan charger as shown on their respective displays. My galaxy s22ultra will also charge at the ultra fast rate on these power banks but only fast charge direct to the belkin gan charger.. weird.
The ruck has a clock on its display when you cycle the display info, the 27k Ark does not.
S22+ only requires 45w from googling, and it’s not about the charging wattage, but the discharge.
Most people don’t have devices that require anything higher than 65w, and they are surprised when they eventually need 100w the power bank throttles after a minute due to thermal issues.
That said, if it works for you, it’s a good buy :)
Out of interest, which Belkin charger?
A likely explanation is the Belkin charger can't do PPS, or can't do the specific amperage needed at the specific voltage needed for the ultra fast charging.
IIRC, ultra fast charging (up to 45W) requires PPS, 10V and up to 4.5A.
The Alogic power banks probably do have PPS so do faster phone charging.
It can be frustrating to figure out, as the companies often don't list PPS support, or the full voltages and amperages possible.
The Alogic power banks themselves likely use 20V to charge. The 20k says up to 3.5A (65W) but may do up to 5A if you are seeing 90W.
The 27k does up to 140 (28V, 5A) but if your Belkin charger only does up to 20V, then 100W (20V, 5A).
@Prong: 108W 4-Port PD Power Adapter WCH010
Correction, it fluctuates 90-95W when charging the alogic power banks
Also like the feature of power pass through with the alogic power banks..
@FarQ: Yeah the WCH010 does up 96W from a single USB-C power. 20.5V, 4.7A.
It doesn't list PPS, so might not do it, so won't charge the S22Ultra as fast as a charger with PPS support.
The Alogic power banks do look good. They are Alogic badged version of an OEM power bank that is sold under other brands.
For example, here is a teardown of the 27k model (branded JOWAY). It looks to be well made.

Pass through charging is super handy. Interestingly while it is often reported that the Anker 737 does not do pass through charging, it actually does. I have not tried with a 140W charger, but with 100W input (20V, 5A), it will negotiate with the device on the output to give up to 90W (20V, 4.5A).
Can I fly with this?
Yes - it is 86.4Wh and the carry on limit is 100Wh per power bank. Or 160Wh per power bank if you get airline permission.
International travel to and from Japan?
I have travelled to japan several times with a 26.8k power bank in carry on with no issues
Ooft, this is a good deal.
From the long term test data I have for the 737 its been fairly promising but the biggest limitation was its RRP and price in the Australian market, with this coming down and being much more available than the ZMI 20, its a solid option IF you are particular about wanting the screen and due to availability.
The cells inside have been changing frequently and it does not seem to use just one manufacturers, so I still have some reservations about QC and longevity beyond 12months with moderate to heavy use, thats one place where Id still suggest the ZMI if you can get one on sale.
shame the alogic ark 27k is out of stock. direct from alogic AU with their current 20% off is $159.96 delivered. 168.79mah/$ vs 162.16mah/$ for the 737
Wow !!!
A 140W Anker !!!
My non-Anker one was able to power my laptop for approx 4 hours last time we had a power outage.
Good to have one handy for such situations.
