5.0 out of 5 starsExactly as advertised
Reviewed in the United States 🇺🇸 on April 12, 2023
So there's a lot about what I like about this product and just one or two things I don't like so first what I like about it is it's exactly what it advertises itself to be not just for the sake of an extremely fast charging battery Bank to and from but just for the fact that you get all the technical information on the screen which is really really nice because I use this a part of my portable solar pad which I like to read the wattage coming in and it does that perfectly and my solar pad is a 40 watt solar pad which is absolutely able to keep up with the battery bank also I usually just keep mine in my emergency supplies backpack I have kept it charged for the last 4 months and in that time it's only lost about 2% you just have to make sure you turn off the screen before you put it away or else it will drain a few percentage every few days The way you do that is you simply just hold the button down for 2 seconds until the screen turns off also make sure you have the auto sense function off unless you're going to use it pretty regularly
I like the three ports especially the regular type USB port for slow charging things there are a few annoying electronics that require that and I've actually been able to use this specifically to charge them which is kind of nice

The cons... It's a little heavier than I expected but not a problem for me necessarily just consider that

Another con is that I keep seeing from several people that sometimes the screen has gone off for them and it no longer comes back on The battery bank seems to still work and operate exactly as intended however for me that would really really frustrate me because I pretty much got this exactly for the screen itself but it has not happened yet and I've only seen a few people say that they've had that problem so maybe do the research to see if you come across the same thing....

I think the last con that I can think of which I really don't like is the trickle charger mode so here's a couple things that you're not going to be able to find pretty much anywhere when the trickle charge mode is activated if you deactivate it you have to wait 2 minutes for that little light to turn off during that time it will still continue to trickle charge and it'll show that it's losing energy even if nothing's plugged in this is just a natural function of the device so don't fret but I had to do some digging to find that out also if you decide to turn the trickle charge back on it's going to be another 2 minute timer so I would just wait it out also when the trickle charge is turned on it's going to affect the charge rate and the discharge rate of the device so consider that with trickle charge turned on I was freaking out the first time because I thought I broke it 😆 All I had to do is wait 2 minutes still I've hit that stupid trickle charge a few times and it's kind of annoying because it only takes a double press it can happen pretty easily if you're trying to cycle through the menus quickly That's about it That's all I have to say I would absolutely recommend this product. I hope my review helps somebody

3.0 out of 5 starsseemingly Loses charge.
Reviewed in the United States 🇺🇸 on May 26, 2023
The good.
fits in the notch of a steamdeck case.
click the button a bunch, or hold it. There's a monster in there.
Display is nice. It's a decent size and very dense.
Seeing output lets you keep any eye on your cable quality and performance.
It didn't seem to get very hot even at high input/output.

The bad.
Seems like it loses SOC just sitting there overnight. Makes me feel like I need to test it's capacity and/or try to figure out what's going on. It was at 100%, now it's at 94%, and it has done nothing but sit for day or two. I don't want to troubleshoot a battery bank.

Takes a while to turn on when you tap the button. There isn't a physical reset button that I've seen, but it's also never locked up or anything.
I've had a UVP error a few times. I think while attempting to charge it. So it seems more picky than any usb-c bank I've used.

There is no hope in taking it apart to refresh the batteries when it gets old. So it'll be ewaste someday.

I'm returning it. Mainly because it looses charge, and because I don't think I'll ever be able to repair it once it's outside of warranty. The software seems possibly a little buggy and a little too drainy.

It's worth mentioning I have a sharegeek storm 2. I hated it at first because twice, it locked up. Also the company snail mailed me and offered money for a 5 star review..... which I reported. However on sale it was a little more than this, and after a year, I can say it's been my favorite and most used battery bank. I've had to reset it twice. And the display isn't as good (reading the tiny battery SOC is hard). But functionally it's been useful and great overall. I'm also still bitter with anker, because recently it seems they are more interested in marketing, and their offerings are just too unfocused. There are so many products..... I would prefer less products and longer life/support. I'm also still bitter for having purchased a 757 from them :) Which isn't an ups.... So take my review with a grain of salt. But these days, I don't want things, that can't live beyond their intended life span. Old battery banks I've refreshed. Though most have never needed it, it's nicer not to toss things. I for sure don't want to toss things because of software :/ I think in this case, with my limited exposure to this device, I'm not convinced. Perhaps if it wasn't snapped together and could be taken apart non destructively, I'd have given it to my mom. Buuuuut I'm going to get my money back instead. I've seen some people mention they've received poor support for this device. Only available via email. Again, I feel I should trouble shoot/validate mine, and I don't wanna.

2.0 out of 5 stars Not what is advertised, very slow charging
Reviewed in the United States 🇺🇸 on March 5, 2023
Style: Power BankVerified Purchase
I have mixed feelings on this charger, but absolutely do not believe it's worth the full price. They claim 140W charging, but I do not believe that to be true. I can't charge it beyond 45W when using a 65W charger with it (granted it could probably charge faster if I had a faster power brick). Charge speed of the powerbank is not my primary concern.

In a teardown video, it's shown there are 4 batteries at 4,000mAh. So my math shows their battery power is at 16,000mAh, not 26mAh, as advertised. While I've always thought highly of Anker, lying about what you are purchasing is not a good look and has killed my thoughts on the company as clearly their standards are not as high as I thought.

I also found charge times to be so slow, you'd absolutely be better off going out of your way to find power than to use this product. Here is what I found in testing:

> Charging OnePlus 8T (capable of hitting 65W over 10V @6.5A with total capacity of 4500mAh) can only charge between 5-12W with an average of 10.1W. It did hit 20W for the first 10-30 seconds, but quickly dropped. While normal top up from 0-100% takes 30-35 minutes, it took 1 hour and 41 minutes to charge from 15% to 100%, which is the longest charge time I've ever seen on this phone. Even the older style USB cables plugged in on a random USB port typically charge at 18W on average, so this product instantly disappointed. So my phone took around 3.5x longer to charge using this powerbank.

> Charging OnePlus Earbuds on a Rapid Charger typically takes around 10-12 minutes to charge from 0-100%. This product has a 520mAh battery. Charging on this charger they averaged only 2W of output power from the powerbank and took 40 minutes to charge from 30%. So my earbuds take well over 3x to charge to full when you account for the extra 30% the earbuds still had.

> Charging my Dell XPS 13 Laptop with a ~7,027mAh battery was the only time the powerbank came close to it's advertised charging speeds. It was capable of averageing 41.5W, with the max supported XPS charge speed of 45W (so the only product I actually got proper speeds). This depleted the Anker battery quickly and showed that the Anker powerbank is absolutely lying about their battery capacity because it depletes the entirety of the Anker battery before the laptop can charge to 100% after charging the 2 devices above 1 time each, neither from 0%.

Total charge between all the devices: ~3-5x longer than if you have AC power, absolutely does not reach anywhere near 140W of output as most fast charge batteries require cooling to be done on the power brick, which this device isn't capable of. While a theoretical maximum of 140W output might be possible if all the cooling is done on the device end and not the charging end, these are largely false claims made by Anker which I can prove do not line up to normal real world charging speeds unless you happen to have a device that doesn't support standardized fast charging (circa 2023 standards).

Would not recommend product if you are concerned about charging times or actual charging capacity.

3.0 out of 5 stars Great Charger
Reviewed in the United States 🇺🇸 on February 22, 2023
Style: Power BankVerified Purchase
Just bought this bad boy and it's nice, but it doesn't seem to charge my OnePlus 10 Pro 5g at full speed,. It's output for charging is 65w, so I was thinking this charger should be able to charge it at that speed, I'm using the cable that came with the charger,. I also used the cable that came with the phone and it only pulls 10.5w when I'm using the phone and 17w when the screen is off,. Maybe I'm using it wrong idk,. But I feel like I should be able to hit 65w, when I charge the battery itself it only charges at 80w, I even bought the Anker 747 wall charger that does 150w and it won't hit 140w,.so idk it's a good device but I was hoping to charge my phone at least at 65w,. Especially when it costs $150,.even though I got $40 off,. I'm also using the first usb-c port(C1) I tried the other one and it's the same thing,. I know this is for laptops, but it should still charge a phone at the speed a wall charger will,. The Oneplus phones have high charging output compared to other phones so I thought this charger was perfect for that, I use it for other stuff too, but the main purpose was to charge my phone at work,. Overall it's a good battery,. Maybe I'm just stupid and using it wrong loll

3.0 out of 5 stars Glad I own it, but Anker sucks now.
Reviewed in the United States 🇺🇸 on April 30, 2023
Style: Power BankVerified Purchase
I mean it's super nice, but I bought it a few days before Eufy (a subsidiary of Anker) was caught up in a lie about their cameras not sending pictures back to Anker. Anker double AND tripled down on that lue before... Not even admitting they were wrong. But acknowledging that they would change their cameras going forward??? Something like that. Made me lose all trust in their brand, but since I already spent the money I still use it and it's a fantastic little power bank for it's capacity. I just don't trust this company anymore to ever buy anything else from them ever again across any of their product lines.

3.0 out of 5 stars Powerful charger but not sold on 20000+ mah
Reviewed in the United States 🇺🇸 on January 20, 2023
Style: Power BankVerified Purchase
First and foremost. I have way too many power banks. I’m a nerd and had to buy the Anker when it was 100 over the holidays. Mainly bought it for the screen and the different voltage read outs but figured hey it’s a 25000+ battery, this gonna last a while.

I know you never get the full 25000 cause of discharge rates etc. but this only charges my iPad twice. I have another 20000+ power bank that was 30 bucks and charges my iPad 3 times. Lol. Not trying to nickel and dime but this thing cost 150 regular price. Guess it discharges faster combining a high output therefor using more energy. Idk. I got a D in psychic class so this is beyond my expertise.

Pros. You can charge laptops that otherwise my 30 power bank can’t.

Looks super cool.

It does charge my iPad suuuper fast which goes back to my point of whether or not high outputs drain more battery.

Cons. Is it 25000 mah?

It’s pretty heavy. It’s a battery but could be used for battery IYKYN

All around. For 100. I’m not overly disappointed but if I paid retail I’d be like “bruhhhhhh”

3.0 out of 5 stars Have not seen it charge at 140W - Deceptive Marketing
Reviewed in the United States 🇺🇸 on March 24, 2023
Style: Power BankVerified Purchase
The power bank capabilities good, but there's a problem with 140W charging. Unfortunately, I have not seen the charger being recharged at 140W with Anker 765 Cable and Anker 717 140W Charger. I purchased all these products from Anker: 737 Power Bank, 765 USB C Cable, and 717 140 W Charger only for them not to work the way it was promised/marketed. I believe it's a ploy to purchase all their products and sort of created an ecosystem, which is fine. I would love to have the 140W charging capability as advertised here.

3.0 out of 5 stars Software fault - leaking 0.1w on port "A" which cut the charging input/currents to more than half
Reviewed in the United States 🇺🇸 on March 9, 2023
Style: Power BankVerified Purchase
I requested a second replacement unit and the new unit exhibits the same problem as the first one. The battery reports an "output of 0.1w on port A" when no device connected (see pictures from other users).

I have a 100W charger and had observed the charge input at 90 watts on port C1. However, when in this fault, the software/circuit limited the charging input to about 60 watts. I believe the software is trying to support both input/output simultaneously therefore cutting back on input currents. You're stuck with this flaw even though it's advertised at 140watts in/out.

3.0 out of 5 stars Its great if it work for your needs
Reviewed in the United States 🇺🇸 on October 14, 2022
Style: Power BankVerified Purchase
Unfortunately this did nit work for my needs. The most I would get out of either of the usb c ports using the included 140w usb cable was about 85w. I tried this on both my dell xps 15 2 in 1 (90-140w) and an asus flow x13 (90-100w) and neither was able to reach the required rating for proper charging.

It does how power passthrough but with some limitation. First your limited by the power supply being used for example if you use a 65w power supply then you will only roughly get about 30w in through the first usb c port and 30w out to what ever you are charging through the second usb c port. Second limitaion is that it only supports up to 140w overall power which means the max you will be able to get in to charge the battery bank is 70w and the max output you will be able to charge a scondary device through the second usb c port is also 70w.

Hopefully they come out with a version 2 that supports the new 240w usb c capabilities that way when you do plug in a 240w power supply you can theoretically get 120w in and out which should work for most high end laptops.

3.0 out of 5 stars TSA confusion (W vs Wh): May cause issues at the airport
Reviewed in the United States 🇺🇸 on December 13, 2022
Style: Power BankVerified Purchase
This unit may cause an issue for travelers. If you tell TSA that it's a 140W (watts of output) charger, they'll tell you the limit is 100Wh (100 Watt hours of output) and ask you to throw away your nice little charger or miss your flight. This unit is indeed within the TSA limit, you just need to let them know its under 100Wh and that the 140W refers to the charging output max and not the actual capacity of the batteries. (learned this one the hard way)

Also, the battery pack specs for this unit say it has 24000 mAh hours of capacity but that doesn't seem to be the case. If I charge my phone (it's a new iPhone 14 Pro; 3200 mAh) from near empty to full, the battery pack will have 80% left. That's only roughly about 16000 mAh total. Granted, it charges the phone very quickly and the display is quite nice. I'm just concerned this isn't really 24000 mAh.
