This is an awesome device. After some quick tests I can say it fully meets my needs and expectations. Yes, it is expensive, and at $150 I didn't think I could justify it. I got it on sale for $100 and I believe it was definitely worth it.
The display is fantastic and really provides all the information you need in order to know what is going on with the inputs and outputs.
My main use will be for charging the 50wh battery in my Surface Pro 8. The Anker 737 will charge it at a 55w rate via either of the two Thunderbolt ports (the supplied Microsoft charger is rated at 60w through the Surface connector), and it appears that the conversion efficiency is about 80%, meaning that it can fully charge the Surface and have capacity left over to charge a phone or two.
(An interesting note about conversion efficiency based on some quick tests and calculations: If I charge my Surface Pro 8 from my Jackery 300’s PD port, it takes about 60wh to fully charge the 50wh battery. It appears that the Anker 737 will need to supply almost 70wh to fully charge the 50wh battery. If I connect the Microsoft AC adapter to the Jackery 300’s AC port and charge the Surface that way, it requires about 90wh to fully charge the 50wh battery. The more up and down conversions you do, the more you lose.)
The supplied cord is rated for 140w and is 60cm long (NOT 6 cm as some have said), or about two feet.
I had limited success with pass-through charging, YMMV. I connected a 45w charger and the Anker started charging at 42w. Then I connected a phone, which started charging at 10w, but the input to the Anker then dropped to an identical 10w. A different charger and a different load might give different results, I don't know.
Others have complained about having difficulty charging DJI batteries. Here's what I think is going on (my best guess, anyway): I have the Mini 2 battery charging hub and three batteries. The hub appears to be happiest with an input of 12v, 1.5a. (The supplied DJI charger is rated at 9v, 2a and 12v, 1.5a.) USB-C PD 3.1 does not appear to support 12v, and when connected to the hub, the hub and the Anker can't seem to negotiate an 18w charging rate at 9v. HOWEVER, when I connect the hub to the Anker's USB-A port using the supplied DJI cable all is well and the hub charges at 18w.
Some users have panicked over the USB-A port showing 0.1a with no load connected. Anker explains this on their support page (which takes some digging to find). 1. Make sure Trickle Charge mode is off (tap the button twice). 2. Wait two minutes after disconnecting a load from the USB-A port. 3. Relax.
Some users have experienced less than expected charging rates. Not all USB cables are created equal. (In fact, back in the early days of USB-C there were some cables that didn’t meet the standard and were risky to use.) Make sure your cable supports the rate your device requires. I bought a six foot, 140w Anker cable to go along with the 737. That, plus the cable supplied with the 737, should meet all my needs.

I purchased and tested both the Anker 737 and the Shargeek Storm2 Slim. All tests were done using either the provided USB-C to USB-C cable or an official cable that came with the device. I plugged in the devices and waited 60 seconds for the charge rate to settle before recording the listed wattage.Being charged via a 140w Apple laptop charger (at 50% battery):- Shargeek via USB-C: 65w (max rate)- Anker via USB-C: 120w (near max)Charging my M1 Macbook Pro (at 50% battery):- Shargeek via USB-C: 91w- Anker via USB-C: 95w- Shargeek via USB-C to Magsafe: 58w- Anker via USB-C to Magsafe: 111wCharging my iPhone 12 Mini (at 30% battery):- Shargeek via USB-C to Lightning: 11w- Anker via USB-C to Lightning: 10w- Shargeek via USB-A to Lightning: 11w- Anker via USB-A to Lightning: 10wResults are close enough that I consider them equivalent. Note I was not able to get my iPhone to fast charge at a supposed 20w with any charger I own but the results are included anyways.Charging my Airpods 3 (at 20% battery):- Shargeek via USB-C to Lightning: 2w- Anker via USB-C to Lightning: 2wPorts:- Shargeek has 1x C and 1x A- Anker has 2x C and 1x AScreen:- The shargeek screen looks fantastic with extremely detailed information about both voltage and amperage draw. Holding down the button lets you access additional information such as individual battery cell voltage and change some settings. My largest complaint is the input section is always displayed even when not being charged leaving only a single area that you can cycle between USB-A and USB-C charge information when both are being used. The screen also has a timer that appears to only ever count up power on time; A statistic I find quite useless.- Anker screen is extremely minimal displaying each plugs wattage and a timer showing you estimated time until fully discharged or charged. While compared to the Shargeek the information is minimal being able to see the wattage of every port and a functional battery life timer wins it for me.Price:- Anker: $100 (black friday)- Shargeek: $140 (black friday)Capacity:- Anker 24Ah - 6x internal batteries (4Ah 21.6v / 86.4Wh)- Shargeek 20Ah - 4x internal batteries (5Ah 14.4v / 72Wh)In summary I decided on the Anker due to the ~30% lower price, 20% higher capacity, almost double charge rate, and higher discharge rate.

- It can charge my Macbook Air 2021 to from 0 to 100% in about 65% of capacity so probably higher than advertised 1.2 laptop charges, more like 1.4 on these M1 Macs.
- You could probably do a week of charging for a normal Smartphone off one 100% battery charge.
- I have a Steamdeck and it's able to give me about 4.5 hours playtime depending on what I'm running.
- It "rapid charges" every device I've tried - Macbook, OnePlus 7 Pro, iPhone 13, Google Pixel 7 Pro, Steamdeck.
- The little screen on it seems like a gimmick but has proved to be very useful and unobtrusive. It's useful to see how much battery is left, what rate devices are charging at etc. Really useful.
- It's noticeably heavy in the hand so I was a bit worried about travelling, but in a backpack I have to say I barely notice it and it's been more useful than carrying around some of my other packs because it rapid charges and I don't have to leave my smartphone in my bag so it can trickle charge for hours.
- Build quality is A++ - it's a really nice finish, well built, looks nice if you actually care what your battery pack looks like!
- Comes with a short USB-C - USB-C charging cable (about 6" long) and a little cotton carry bag. I would personally get some high capacity, longer charging cables. I bought some rated for 100W which it can deliver although highest I've managed to find is a 40W draw off the Mac.
A few things to note before buying:
- There's no charger boxed in so you will need a 40w USB-C charger to charge it at highest rate - most modern smartphones or laptops will have one rated that high. It will not charge off low power USB-C connections, e.g. the hub in my Dell Monitor (which my MacBook Air will charge off), so you may want to factor this into your purchase.
- It is a more expensive device relative to others but I think if you travel a lot and you need the capacity this is an excellent device. They have not skimped on the quality and it is now part of my daily carry.
- The quoted "120W" charging is an aggregate of all 3 ports (1xUSB-3.1, 2xUSB-C) at full rate. So for example you could charge a laptop, a smartphone and a camera all at once, all at full power (I think. I can't say I've ever tried to do this!). You can't plug a kettle into it ;)
Thanks.

Anzeige der Restdauer beim Laden der Powerbank auch sehr gut gelöst.
Die Materialanmutung ist leider nicht so gut, wie bei bspw. beim 735 GaNPrime Charger. Das Teil ist ein richtiger Handschmeichler. Diese Powerbank wirkt im Plastik-Vergleich dazu "billig".
Kleine Gumminoppen auf der Unterseite wären noch gut gewesen, damit das Teil nicht so herumrutscht. Kann man aber auch selbst nachrüsten.
Aufbewahrungstipp: mit dabei ist zwar ein "Beutelchen" zum Verstauen. Ich habe allerdings , weil es aktuell noch kein anständiges gibt, ein Case für einen Anker SoundCore 2 zweckentfremdet. Die Dinger haben sehr ähnliche Abmessungen, sind lediglich etwas länger. Passt wunderbar.

Talked with their support that I needed a replacement as soon as possible and got back saying they would send a new one before receiving the defective one. When I asked the expected delivery date they then said it would be one week after they received it. Very poor customer service for an very expensive powerbank. Had to buy another one from another brand and returning this to Amazon
