One of my most anticipated videos yet and its great, keep up the great work!

Thanks!

[@lokster0986]

probably the only channel wtih actual values when testing! more power to you sir!

[@AllThingsOnePlace]

Thanks for watching!

[@thelaughinghuy]

thanks for the review! very helpful to see actual Wh figures instead of the misleading mAh and claimed Wh from manufacturers. My request for future power bank reviews are Anker A1335 and A1340, Ugreen 90597A, and Aohi AOC-P008. Keep up the good work, cheers!

[@AllThingsOnePlace]

Thanks for the suggestions! Yeah, there are so many power banks out there, I will never get them all done but the next big one is probably the UGREEN 145W power bank.

[@aggellos2001]

Nice, as soon as I saw the new Anker series I waiting for a review. Interesting to see the big one which also have Bluetooth capabilities.

[@AllThingsOnePlace]

Yeah, it's a battery in a box, you keep near you, really don't know why it needs Bluetooth. I don't want any Anker app that's all I know! They have a bad track record.

[@zzevv]

Couple months back I went into the rabbit hole of looking for a power bank that can do 100W to charge my laptop and came across your channel. Watched most of your videos and didn't find any that suit my needs. Went deeper and found out about the ZMI, ended up with the QB826 (no 'G'). Difference is it can only do 100W out and 60W in. Have to say it really is pretty efficient at max output! There's still a good amount of juice left after charging my laptop. I've also been using it as a power supply with a trigger. Have it for about 5 months now with heavy use and is still amazing for its price. Got it for about $90!

[@AllThingsOnePlace]

Nice, yeah, the G was much more requested so I went with this one. Honestly, the performance of what you have makes a lot more sense for this battery size.

[@alexandernl6310]

[@snoeffect]

Yet another great video, thanks AllThingOnePlace! I looking at the ZMI no 20. You mention safety listing for US and ZMI states it too. But of all the videos on KZbin, none actually show the UL Logo on the unit. Is there one on it some place?

[@AllThingsOnePlace]

UL writes or confirms the standards but doesn't necessarily do the testing or mark every product, they do get the recognition. In this case, SGS did the testing and marked the product. There are many companies that do this, technically all equivalent to UL.

Expensive, but still cheaper than the Tanker Extreme from a couple years ago with better performance (if you need to charge a laptop @ 100W). Thanks for the testing! Edit: I went back and checked, that was $250 in 2019, so this thing for $160 is MUCH better!

ZMI price in Thailand much cheaper than Anker, ZMI only 80USD while Anker 240USD. I am going to buy ZMI for my steam deck. Thank you for the final answer, I have been waiting for long. I though Anker was much better because it was more expensive. I got Baseus charger like your comment, it works like King. I always come back to your channel for great education.

[@AllThingsOnePlace]

Thanks for watching! Also, great to hear you've found some good devices!

[@enkeduenkedu]

Appreciates all your time and effort..❤ my question is: did you consider reviewing those products in terms of keeping their performance after usage of 3-4 months..? (Also consider their charge/discharge cycle?)

[@AllThingsOnePlace]

Yeah, I do continue to check them. I haven't had any fail, but if I do you know it will be getting mentioned, ha.

[@Clownfinger1973]

Great side by side in depth review, thanks for your time and effort. What powerbank would you recommend to take on a long haul flight please?

[@AllThingsOnePlace]

I’m going to take this zmi one on a 9 hour flight soon. We will see how it does.

[@cian.horgan]

I assume the charge level misread of the Anker is because it's using a very simple linearish voltage conversion, so that extra half an hour at the end is the constant voltage section of the CC-CV curve. Does that seem reasonable in your experience?

[@AllThingsOnePlace]

It does. If it strictly reads the voltage as the charge level it wouldn't know that it isn't really at 100% yet.

[@himshurai]

Hi, awesome reviews! Have you gotten your hands on P23 CUKTECH P Series 25000mAh? A face-off with the Anker 737 will be cool to see!

[@AllThingsOnePlace]

I wouldn't face off between those two specifically, I probably should, could reuse lots of old footage but that's cheap, I like to face off between new contenders in each video then I compare the data with others. I still need to get a searchable database of power banks going.

[@TwilightSirius]

Speaking of Power Banks that last long (and doesn't overheat quickly), have you tried testing INIU Power Bank B63 (25000mAh)? If not, will you be testing them soon? It seems that there are a lot of people buying it for their Steam Deck/ASUS ROG Ally. Do you think it would be the best value power bank for those devices?

Great video thanks - looks like the ZMI unit is not available on the UK Amazon, I came here looking for a Power Bank that could be used as a UPS for a mobile router that I use as a back up in case of internet failure, there may be a better solution for that - do you have any links to content on this? The mobile router does come with a battery which has failed so it I thought a power back UPS would be a good way round this.

Yeah, I have a few dedicated 'UPS' devices here but haven't made a video yet on them.

[@yazanayman7916]

i have a couple of questions, i live in nigeria and getting these things is a bit hard and a long process i recently ordered this and the 140 watt 737 from amazon. do you advise i wait for them or cancel the order i want to keep one with my mom and one with me thats why i got them both also does the 20k 200 watt prime powerbank support bluetooth and which one supports pass through charging between them thank you please reply.

[@AllThingsOnePlace]

They all support passthrough charging. The power in that mode does vary though. The 737 is still a good power bank and ultimately has more features and a larger battery versus the 20k 200W prime. I didn't see any bluetooth option on the 200W power bank, the 250W definitely has that but I didn't try it out.

[@dinosoarskill17]

I've bought probably 7 power banks this year. It started with a quest to find 30w charging for my drone, and now I've just spiraled out of control. Last one I have coming in is a Shargeek Storm and I think that's it for me...

[@AllThingsOnePlace]

haha yeah, I know the feeling. I tried that one Shargeek power bank that was enough for me, that was a disaster of a power bank, but I didn't check out the storm power bank, I did put it in the too expensive for what you get category. It's still on the list but it's last.

[@FishingWithMookie]

Will the first power bank u showed in the start of the video will charge my go pro without battery in it all day ?

[@AllThingsOnePlace]

That should get you a very long run time out of the gopro. I recommend a battery in gopro still so if the power bank goes flat or a USB negotiation fails the camera doesn't lose power and lose whatever you were working on. That way you can also pull the power bank to recharge it and reconnect as needed. In terms of going 24 hours not sure if it will make it that long. I know the bigger one does. I never actually measured how much power the gopro uses (and for that matter which generation).

[@graxxor]

That ZMI name drop what actually EPIC!!! LOL. Also, is this the Anker Power Bank that was found to be a bit melty?

[@AllThingsOnePlace]

I didn't find anything on these like that, they both shut down safely at reasonable temperatures.

[@CaseySuper19]

On the back of the Anker is says 10,000mah? What does this number mean? Is it the actual usable power? I've noticed all Anker power banks show a different number than what advertised on the back. Like the Anker 737 says 13,500mah on the back. Also you said the Anker power bank should really be a 50 watt powerbank...do you mean 50 watt on each usb-c port or 50 watts total across all ports at the same time? Thanks, love all your videos!!

[@AllThingsOnePlace]

Manufacturers will list the capacity at other voltages, it's confusing since they sometimes have capacity estimates or losses of converters built in but sometimes don't. It would be easier if they said it can supply 60 - 65Wh of energy or something along those lines. It isn't a safety concern so never going to happen. The Anker is very efficient and makes great use of the energy at 50 watts of power. It charges at about 50 watts and doesn't get to warm discharging at 50 watts. So, in relation to the battery capacity and performance it is a sweet spot of operation. At 100 watts (one port multiple port, doesn't matter), it starts to struggle, then at the 200 watts it's marketing nonsense, minutes of operation.

[@CaseySuper19]

That makes sense. Thank you for the detailed response!

[@googoogagaga]

Appreciate this video. Was just wondering which power bank can do 45w super fast charge on samsung phones?

[@AllThingsOnePlace]

The ZMI and this Anker have the mode to do that just from memory. The basic requirement is a 5 amp mode within a Programmable Power Supply, PPS output, typically devices will have between 11V and 21V maximum for the PPS mode if present. The challenge is current, if it can't do 5A it will drop to the 25W charging mode, if it doesn't have PPS then it will drop to an even slower charging mode.

[@GuttzTV]

hi. about PPS, did you observe any powerbank use this feature while being charge? from all i can see, only usb c devices being marketed using the PPS, never the powerbank/powerpack themselves. why is that?

[@AllThingsOnePlace]

I don't have direct experience with the non g variant but I'd expect them to be very similar performance wise.

[@abeetbored]

would this test for ZMI vary very differently for the QB826 model? it's the only model available in my area

[@AllThingsOnePlace]

I think the electronics are a little different, so less power capability overall, but I would expect a company to share as much as possible between them, considering the ZMI only does 100W continuously anyway, the QB826 is probably a better option.

[@andresdelosreyesaguilera3648]

What advantages would the Anker 737 have over the ZMI? Both of them seem to have almost identical performance right? I don't know about the actual 737 battery life, as they said only 300 cycles for 80%, but idk if that's real, as people seem happy and 300 cycles are too litle. Here in Spain the price is identical for both of them btw.

[@AllThingsOnePlace]

Yeah, I think in that case it comes down to form factor. Rectangle or square for an end profile.

[@AlTheEngineer]

I watched so many of your charger and power-bank videos. Honestly, which one do you recommend now in 2024? I would like to buy a wall charger and a power bank before travel, phone + laptop charging. What is your opinion?

[@AllThingsOnePlace]

So, the Anker 100W Prime is probably the better option as a power adapter, for 100W it is very light, you may need to hold it into the airplane seat power sockets since they are so worn out... but you get a decent amount of power for all of your devices, be careful here since it technically exceeds the power allowed at an airline seat, '75 watts', but I'm not sure it's really watts... An adapter would be required for whichever country you are going to. I used it internationally and it was great. The power bank really depends on your needs. I took the ZMI around the world also but that thing is a monster. The Iniu power banks are a bit smaller and yes, have less features, but if portable is the game, they hold up.

[@AlTheEngineer]

@@AllThingsOnePlace I really appreciate your response and help. Yeah I owned the 150W Anker 747 GaN charger and I got rid of it because it really annoyed me on travel, it would basically fall out of every socket! It was so annoying, they give that little suction caps thing with it, but its not really effective as not all sockets have flat surfaces around them for the suction caps to work. So I ended up getting rid of it as powerful as it was. I think I'd like a desktop form-factor charger, as small as possible. I was watching your review on the UGREEN 100W desktop charger with removable cable, do you think there is a better one out there? Maybe higher power but same form-factor? For battery bank, I might actually settle on the Anker 537, size-wise and weight + 24KmAh at 65W might be good enough for my needs, do you have anything against that in your opinion? I appreciate your time and the reply! Thank you!

[@AllThingsOnePlace]

@@AlTheEngineer Yeah, the removeable cable makes sense. There are a few options out there, a lot of them struggle with isolation issues, meaning high leakage AC current through the adapter. I agree the suction cups were terrible. That sounds like a pretty good option for a battery! Plenty of storage and plenty of watts.

[@AlTheEngineer]

@@AllThingsOnePlace I ended up buying the ZMI as per your recommendation after much consideration and using your link! I also ended up buying the UGREEN 160W adapter with a 5 foot extension cord, I'll make it into a desktop charger :D thank you for the help!

[@Millzlane]

Question... So If 100w only last for 10 min then go to 50 "or so", it should take 1hr and 6 min. Do you think it would be better to buy the 67w charger? Bcuz it should charge in 52min if it doesn't overheat. Wait 🤔 You don't think it will overheat, right? Lol

[@AllThingsOnePlace]

The 100W charger will actually be operating in it's most efficient range where the 67W charger would be near it's maximum output, so the 100W charger is the better choice efficiency wise, 67W will probably only add a few minutes to the charge time though. I don't know why it limits the charge speed to 50W after such a short time, it doesn't get hot on the outside but better safe.

[@Millzlane]

@@AllThingsOnePlace I meant as far as for this bank. 🤔 what I was lookin at though was that ok let's say even if the 67w gave me 60w constant. It's better than 100w for 10min followed by 44w for the rest of the charge 🤷🏾‍♂️ (I seen another channel charging it at 100w and it got dropped to 44w. So it's actually less than 50w) But I got the 67w on the way. I'll see what happens. Anker Gan 67w.

[@PeeGeeTips]

Which is the better buy for sustained powering of a 2017 mbp? I’d prefer the flatter profile of the ZMI but if the proper 99Wh of the Anker is best overall I’m content with that. It’d be for a mobile laptop rig when I’m shooting tethered photos to the laptop and I don’t have access to mains power, however, if there’s pass through charging of the power back when I do have access to mains power that’s an even better bonus, what’s your advice?

[@AllThingsOnePlace]

So, the trouble with all of these in pass through is they won't get you full power so I wouldn't count on that. The anker will get you a little more run time for sure. The ZMI is close though so I think it mostly comes down to your preferences and needs. If run time is above all else then Anker.

[@Ender_Wiggin]

While it does allow more power out than in this should be easily address by making sure you always have a large USB C charger and don't over draw to much power from the output. In my case I will pair it with a USB C charging hub and connect my PIs up to it. The battery will always be charging more than discharging and during a power outage it will last as long as the battery. It could also be used for a "router UPS" if you use a USB C to 12V barrel Cable. Maybe a better UPS then most. The last question is value.

[@AllThingsOnePlace]

Yeah, I am actually thinking about setting this up as a router UPS, see how it does, a regular UPS wastes several watts as well so if this is comparable to that it may even be more efficient. I just hope it doesn't try to continuously charge the battery, it'll swell that pack up fast.

[@Ender_Wiggin]

@@AllThingsOnePlace Ya I am also concerned with the continuous charge problem. I now pass-through charging gets around this by bypassing the battery entirely. The question is how the ZMI does the power path management and if it can disconnect the battery completely or if the battery always has a floating 4.2V on it. It is a solvable problem but needs to be thought about at the architectural level. Also, most all-in-one IC do not support it so it is not straightforward. I have considered doing one my self for a while but unless I made many trips to China I could never hit the price point where it would make sense. With that said sometimes all these Chinese markets need is a good reference design to copy from and then the market will be flooded with cheap versions of them.

Theoretically, on the ZMI, you can charge at 100w from th C1 and discharge at 100W on the usb-A (using special supplied cable.". Can you test and confirm?

[@AllThingsOnePlace]

It does not do that. It shuts the USB A port off with USB C port charging.

[@stellarproductions8888]

I don't think our government will ever force these companies to state legit numbers, and none of these fudgy ones. To be honest, I really don't think the 200 watt adapters are ready for prime time. If heat generation is the biggest issue other then cost, then companies should consider making the case entirely out of metal, with heat sink style fins on the sides, and make sure that the case is making contact with the transistor chips with a thermal pad between them. This would dissipate heat quite well! Another thing they could do, is install a small fan inside, like they do on inverter units. But only problem with that, is the fans would draw power off the battery, ruining your runtime, and would make noise, since the fan is so tiny. When a power adapter claims 200 watts, then I want to see a single port putting out 200 watts to power a thin and light notebook. Simple!

[@AllThingsOnePlace]

Yeah, one company did put these in metal cases with fins on the outside, they had to pull them off the market for overheating still, probably like you said, not internally designed to get the heat out either. The other issue is temperature of the case. If it is a metal case it transfers heat better but that also means it transfers heat to you better so the external temperature allowed is much lower for metal cased devices versus plastic. Plastic and a small fan makes the most sense for devices that have to dissipate some heat though concerns of device lifetime then pop up. That or make it way more efficient. GaN should actually be in power banks, it's great for DC-DC converters.

[@alx9r]

Around 7:20 you comment on the “UPS” capabilities. Can you elaborate on the behavior of these? The application in which a power bank can be used depends to a large degree on what it does when connected to both a load and supply. The possible behaviors seem to be as follows: 1. Charge the battery, don’t power the load 2. Don’t charge the battery, power the load 3. Charge the battery, power the load 4. Drain the battery, power the load The Anker 737 does (2) which makes it pretty useless for all applications I have to spec for. I think you meant the ZMI here does (4), but I’m not exactly sure. I didn’t hear you say what the Anker here does, which is certainly something I’m interested in. I think many users will ultimately find that these higher wattage power banks will often be connected to both supply and load. That behavior differentiates the lineup more than most of the other attributes, currently. Thank you for all this testing, I find it very helpful.

[@AllThingsOnePlace]

The ZMI does 3 and 4 as far as I can tell. I don't know the internal architecture though so not sure if it can switch between states. The pack always keeps the power flowing to the output, even if there isn't enough at the input. So, with a larger load versus supply it will discharge the battery slowly. The other unknown is if it will keep the battery at float which isn't great for lithium ion batteries. The anker has negotiation issues with power in and out so does 1 or 2 depending on what was plugged in last. In the supply only case it seemed fine. I am curious if this would get stuck in a loop.

[@alx9r]

That’s too bad about the Anker, I had high hopes for the successor to the 737. I’m still puzzled by what usage configuration, exactly, Anker is imagining for these high power, high capacity power banks.
