All of my charging cables are INIU. Nice to see the results reflected here as well. I was going to add the bit about capacity but I see someone else has covered that. "Doman Stuff"

@@ProjectFarm I am an EE as well and 'INUI' is a junk brand. i test four of their chargers as a Vine Reviewer on Amazon and while actual A hours capacity new was only a 20% exaggeration, the number of cycles fore failure was abysmal, as low as 100 cycles before failure whereas anker, ravpower and other actual name brands have gone over 500 cycles no problem. if you notice all the long term reviews people have problems with INUI. These are pump and dump companies buying class b or worse cells or quality control fails in bulk. They rely on early reviews that can reflect capacity, but by their nature don't reflect low number of cycles one gets.

I've been looking for a review of those larger banks that you can take with you camping that aren't gas powered. They have at least 1 full 120/240 W outlit.

Thanks, will do! Thanks for the suggestion.

[@lanzer22]

Oh yeah, those lithium power stations are everywhere now and no one knows if any of them are trust worthy. Personally I opted to buy the battery and inverter separately. That way I could swap the battery or add another one if needed, and the inverter never need replacing and will always have more power than those found in the power stations. You can find videos on KZbin showing these DIY solutions. As for the brands, many solar and lithium battery channels test them regularly. Brands like LiTime or Weize get mentioned a lot and I ended up getting LiTime myself.

Biggest takeaway from this one is how shady and misleading these popup companies are with their capacity ratings, knowing most people will never know. Thanks for the tests!

[@ProjectFarm]

You are welcome!

[@Piasecznik72]

Yep, that is why from all chinese brands I chose anker and baseus. They are fairly honest about what they sell, considering how much scam is present in chinese Lion battery market. PF performed 18630 cell tests which shows how far off they can be.

[@Dmeech100]

The mah is listed using 3.7v calculation because that’s what all these cells are, he drained them at a higher voltage which means there are some conversion loses which reduce the mah. Calculate the mah using the batteries cells voltage and you’ll see that they all come close to stated capacity. Now in the real world all standard usb-a devices run on 5v, so yes it’s a clever marketing trick to use batteries 3.7v to show a higher mah rating, but if he set his tester to draw 3.7v on all of these, they would come close to mah capacity stated on battery.

[@nexaentertainment2764]

You're absolutely right that many companies deliberately lie about it. But in many cases it's also semantics. It's like how hard drive manufacturers say 1gb is 1000Mbytes for advertising purposes, but it gets calculated as 1024. Basically these battery ratings are for the ideal max best case. Like the actual power the battery can hold before conversion, heat, resistance, etc, inefficiencies.

[@White000Crow]

@@Dmeech100they are using those magical 9000mAh cells as well. Quite a few of those cheap cells have been proven to deliver 20-30% of their actual rating. Looking at the packaging of these chargers they appear to be using pouch cells.

Anker’s had a decent reputation for a while, but I’ve had good luck with Baseus and INIU recently and it was cool to see how they did.

Any that you’d recommend?

[@ridiculous7935]

It is illegal, just no one goes after them and most of these companies are offshore Chinese companies. Really need to see some litigation and cracking down on false advertising. Now in all fairness, the output capacity is not the same as battery cell capacity. So its reasonable if the pack only outputs around 80% of advertised capacity. But results like 20-60% of actual advertised capacity is a lie and should be litigated in court.

We have the Anker. When we go on family trips it's always a challenge when the kids run out of battery and start asking for chargers at about the same time. The Anker can charge two devices at the same time, and fast, and has a large capacity. So for us it was well worth the money. And it is built well so has lasted over time. We first tried one of the cheaper Chinese brands that came with two, but even though they both worked well enough, they ended up falling apart after just one trip, cases breaking or just stopped working.

[@Nomaxice]

I got that big boi Anker 'cause I needed something that could charge my laptop too (as it has dual input with a classic barrel input and PD input at 100W), glad to see it performed very well in those tests, in line with my experience! Another great review, love seeing the data, I would have maybe enjoyed seeing a price per Wh comparison though, after all while certain brands love to overstate the capacity, they could still be a decent value for their real capacity! Hope to see another review of battery banks around summer to see how (badly) those solar equipped batteries perform for "in the wild" power generation.

Good comparison and useful to a wide range of people. A suggestion for any subsequent comparison - it would be more useful to compare power banks of similar capacities as the different sizes/weights have different use cases - the lighter/smaller ones you would probably carry in a backpack/purse/messenger bag while walking around town/hiking; while the heavier ones maybe would be stored in a vehicle or at home for emergency uses.

Plus phone batteries are getting pretty big these days...a Pixel 7 Pro could easily hog up some of these 5000 mAh banks all by itself!

He does have one on rechargeable AAs that I recall. It was from a few years ago. It would be good to see an update, as several new brands have hit the market since then. I suspect most of those brands are... suspect. I use rechargeable AAs and AAAs for most battery-operated items at home, include A LOT of the kids' toys. Fujitsu has been my go-to brand, but it may not be the best value anymore.

[@lonewanderer3603]

He's already made that video. If I remember correctly, he likes the eneloop batteries. You might want to dig through his playlist.

[@missingnola3823]

​@@lonewanderer3603I think you're right on eneloops being the winner. Here's the story and why I like Fujitsu: Sanyo developed the tech behind eneloops - what made them special is that they don't self-discharge hardly at all just sitting idle, as was very common to nickel metal-hydride battery chemistry. Panasonic bought Sanyo, but due to Japanese anti-trust provisions, the factory that produces eneloops was bought by Fujitsu. Panasonic eneloops are made by Fujitsu. The speculation is that Fujitsu rechargeable batteries use eneloops tech and I've gotten nearly identical performance from them as basic eneloops, but at a slightly lower price. A few years ago, Chinese made ni-mh batteries often had bogus capacity ratings, didn't hold up, and self-discharged quickly. There were some brands that were good on capacity and durability. With all the new brands, I'd be curious which are legit and whether any have closed the gap with eneloops.

In all honesty, they are the one brand I trust to not fry my devices or go up in an Inferno lol...

[@freakyfox5229]

I think the batteries used in the slim models are bad. Had a slim that "only" lasted me 3 years. And some other Anker power banks that still work almost as new, 5 years later. Around 90% of original capacity left.

[@ulogy]

​@@freakyfox5229If you read their product details, you'll note that the slim products are their first generation of LiPo pouch batteries, as opposed to their regular Li-Ion (18650 or similar) batteries. They work well while they last, and output exactly what's advertised (the safe peak), while having the functions described, but yes, longevity is impacted, particularly if you charge at max speed all the time (heat kills batteries, I'd be surprised if any of the devices hitting 15+ watts over their non-standard charge ports last even a year if you stress them daily.)

[@Joe-wk9ow]

Great tech review. I have a zillion USB current testers and a handful of electronic load testers as well. One note: Anytime you start throwing adapters on to convert between A and C (or 5.5x2.1 or whatever flavor) each one takes a bite out of the current draw due to their designs. Many adaptors and short cables can pass only 1 A while others happily do 3-4-A. Stock up on a number and always test them with same load and source and find the ones that lose the least amount of current as they have such a wide range of quality. Also using De-oxit on the connectors can help ensure lower amp loss as well.

[@graffie]

Good point. The cables have a big impact. Should also take into consideration if the charger is actually smart and can switch to higher voltages.

[@DJDTHTRP]

From my experiences, I have used only some older Anker PowerCore 20100 packs with presumably 18650 cells in them, and they have only micro-USB input ports, with the larger 337 (PowerCore 26000) having double inputs. They're all I need for what I have, and hold well considering that I cycle through using them all, and recharge them on different circuits in the house or hotel. At home, they are certainly put to use in power outages. Conceivably, if you can carefully open the casings of these aforementioned models, then you could repurpose them and the circuitry with new 18650 cells when the inevitable happens; though, at that point, it may not be worth the effort, and instead look into making your own power banks with new casing materials and to suit specific use cases. For what it's worth, thanks for covering the 737 model, as that is an impressive one. Anker as a brand tends to hold up rather well on average, and I've yet to have a bad experience with their charging bricks as well as their cables. I'm especially careful to not push these things to their limits, granted, which probably has a lot to do with my positive experiences and reliability. Perhaps we can see those get tested in future videos. I wouldn't mind seeing more of these power banks tested, but there are larger form-factor ones that include full-size AC power plugs on them. I believe there's some you can test like the ChargeTech PLUG, which is generously big and I suspect may have 21700 battery cells inside it; I have one of them, and it's kept specifically for usage during power outages. I believe you will have to draw a line at some point, stopping short of those called "generators", which also have the capability to take solar inputs; those larger ones would be quite an expensive undertaking, especially if you wanted to go into the potential of seeing real-world conditions on how much you can get on using solar panels for the input alone on charging them.

These have to be both effective at cleaning, and not cause damage to delicate circuit components, contact fingers, connectors, printed circuit board traces, components, insulation etc.

[@Jeffcvt]

This is exactly the kind of testing we need on power banks. I don't know just how common the knowledge is that some of them will simply give false ratings for their capacity, but it's something I've known for years to watch out for, and it's pretty much impossible to know ahead of time without other people like you reviewing them and putting the information out there. I would love to see more reviews on power banks moving forward, in both more expensive ones and even in this same price range again. Just to keep a somewhat accurate tally as new ones come out to see what is good and what is not. I'd also love to see some store brands that are from physical stores, with the store they came from included in the review. (For example, the ONN brand from WalMart.) I'm curious if you would find that they're just as bad at not meeting their advertised capacity or if you'd find an affordable option or two that gives you exactly what they advertise.

[@ulogy]

Issue is he's boasting about the power output of some devices with aren't compliant with any known standard and may not be communicating with the host device properly. 12W should be the hard cutoff for any device not advertised as having a specialized charging standard (QC2/3, USB PD, etc.) and definitely shouldn't be outputting more than that with an inline tester that isn't advertised as having such. Faster=/=Better with lithium pouches. I'm trying not to be a wet towel, as PF normally brings the good data, but I feel he may be slightly out of his element with this one. (Evidently the small engine repair god may have low lithium content!)

Good test. Like all on this channel. I love it! Couple of tips: - It would be great to test the ability to quick charge the devices (e.g. support of the common standards such as Power Delivery or QuickCharge). Some mobiles support one way, some the other. Powerbanks with Power Delivery support may actually be able to charge a notebook... we are going to test that! - Another useful feature of powerbank is passthrough charging - when you connect empty phone to a half-empty charger and plug it to power socket, it should ideally start charging up both devices - or phone first, powerbank then - or it may totally go crazy and you need to disconnect "something" for the devices to act properly. How do the tested powerbanks behave? - Quick charging the phone is one thing, but can the powerbank itself be quick charged? Some of the beefy 20 000mAh powerbanks actually do NOT support quickcharging so it takes 20hrs to charge them up! Not Very Impressive!

[@vintagemotorsalways1676]

Thank you for taking the time to test these, there really are a lot of falsely advertised power banks out there! For future power bank comparisons please also consider factoring in their USB PD capabilities (what voltage does it charge at, what voltage can it deliver), plotting voltage droop as current load increases, actual physical capacity (disassemble and see if they are under-provisioning to increase longevity and how much effective capacity loss there is from conversion between the native cell voltage and the voltage being delivered), and capacity over charge discharge cycles (longevity and degradation rate). Some batteries seem to charge over and over without giving out while others can't keep up.

[@ProjectFarm]

Thanks! Thanks for the suggestion.

[@DomanStuff2022]

Interesting video, as always! Very important thing to note; most of the time, maker of powerbank states internal battery capacity, and NOT it's output capacity. So... ieg. company states 5000mAh capacity, but it's battery capacity at 3.7V, so it's 18.5Wh. Now multiply it by about 80% conversion efficiency, and you've got 14,8Wh (ieg. = 2,96Ah@5V). Most of the time this calculation works within 5-10% margin of error.

You're exactly right. The ones that are way lower than that percentage are just lying about the capacity, but the Anker, for example, is spot on what they say it is.

[@dogukancil5128]

Hey man! Fan of the channel here. Love your mechanical stuff but this is like comparing apples and one gigantic orange. PD specifications allow for different voltages and current capability. 5/9/12/15/20/28/36/48 volts at 5 Amps max for PD 3.1, which is the latest revision. These power banks have different PD specs, at different price points, hence the variance between the anker one and the others. This would have been a much better comparison and a product guide if it had mentioned different PD specs. Baseus also has a pd 3.0 power bank capable of delivering over 100 watts, so does Shargeek storm 2. These power banks can do 20V at 5A but the other ones you've tested can do 12V 2A or so. They are not for the same use cases. In order to test properly, you would need a pd protocol tester, power-z from chargerlab, which is another youtube channel, is good. Voltage drop, for which you need a multimeter, and ripple test, for which you need an oscilloscope, are also useful. These power banks employ switching buck/boost converters, so the output might be noisy if the filtering circuit is not adequate, which is not great for devices, hence the need for a ripple test.

[@Snayperskaya]

Great video as always,, but if I may give a suggestion for a powerbank (also applicable to USB chargers): Most powerbanks nowadays offer different standards than just the standard USB charging (up to 5V @ 2.4/3A), such as Quick Charge (QC), Power Delivery (PD), etc. Those modes allow for higher voltages and currents (marketed as Fast/Turbo Charging), but for testing those, you'll need either a USB trigger/decoy device or a USB test device like the FNIRSI FNB48P/FNB58 that can trigger those. Some USB load testers also offer this feature. Another suggestion is testing the standards that the manufacturer's put into the model's specs. Some manufacturers like Baseus even gives information about the specific maximum rated cross-loads between ports. A cool feature of Power Delivery (PD) trigger feature is that you can use a powerbank or USB charger as a regular charger for stuff that don't use a USB interface, like external HDDs, portable electronics with barrel jacks, etc. There are even custom cables with built-in PD triggers, so you can use a modern charger with a laptop that uses a barrel jack or non-standard plug.

I take it with me when I leave, I use it, and when I get home, it sits there until tomorrow, charging.... So, 4 hours or 12 hours, is kinda the same thing to me.... As long as it's charged in the morning, I am fine.... I liked the Anker 737.... I like that capacity. If I need it, I need it.... Little teeny chargers that might barely charge my phone 1 time, are not what I'm looking for.... I would be curious to see the solar, but you'd almost need to construct your own light box, to provide a constant known consistent light source, so that the comparisons would really mean something..... I'd be curious to see a test of what $80-$100 bucks gets you.... Maybe like 1 real name brand, and 3 Dura-Kung-Pow Chicken no name types..... What exactly is Dura Kung Pow Chicken?? I'm not even sure, but I pick up a couple orders from a place near my house on the way home from work, and it's pretty good.....

Love your videos! I've been thinking it would be nice if you could do a test on shears. People on forums are always recommending ones with ridiculous price tags ( in my opinion).

Thanks! Thanks for the video idea.

Thank you for all your videos! VERY Helpful! You did a great generator one and now this power bank one, but can you also do a Power Station one? Brands like Jackery, EcoFlow, Anker, Halo, Bluetti are few I've seen as recommended and personal have a smaller Jackery already, but want to purchase another. Curious how noisy others are compared to the Jackery and other things like performance, charge time, etc. But who am I to tell the master how to do it :) Thanks again for all you do!

Thanks and you are welcome! Thanks for the suggestion.

As usual, phenomenal video! I'm a little disappointed there weren't more unexpected tests, but then again it's a power bank and they're pretty simple anyway. I'd love to see you test out Foam Cannons (for auto detailing)

Thanks! Thanks for the suggestion.

It's a powerbank and it does not need to be simple. You have many models with many features.
