Otao 200 Watt USB Power Adapter Review and Test 

Thanks! Yeah, I have a long way to go. The bin of untested things grows faster than I can get videos out. I think I have something like 50 power banks to get done.

Yeah, this does the job of being a power supply quite well. I obviously question why they didn’t go through with approvals and such.

One thing I would love to find is a more usb ports but lower output, since retro consoles don't need that much power. Would be nice to have multiple consoles use one outlet.

@@LinxESP I guess you could go 1 usbc 9v to a female barrel output and then attach a barrel chain to it... and be careful of never turning on more than 1 at a time... maybe that could work

@@ferna182there’s something out there called a usb-C trigger module that you can get with a barrel jack they’re pretty interesting, some have buttons where you select your output voltage

Yeah that is a good idea to use a smart plug to disconnect power to this device when not in use. At 200w in the box it should be able to charge quite a lot at once.

Glad you like them!

@@AllThingsOnePlace you're adding so much value to the internet with all these tests. Much appreciated.

It's a big charger, large surface area, and not operating at it's maximum wattage with those devices helps keep things cool.

@@AllThingsOnePlace I also got today the Duracell M150 and I must say this thing looks and works amazing so far. Really nicely done. Wish I could post pics of it on here. Can you please take a look at those? Would love to know your thoughts on them. They have two models. I got the 150 W one.

Yeah. It is fun.

Thank you for watching and the comment!

@@AllThingsOnePlace your kind serious attention to detail is a pleasure to take part of. Vielen Dank!

Yeah, there's lots to come.

Thanks for the feedback. Yeah, I am trying to put the all back in the things in one place, ha.

I plan to do another round of best USB adapters later on this year.

Thanks! Yeah, RU-vid ebbs and flows. Although, so far, this year it’s been just one way, haha. I should just not look at the stats. The comments are always great. Like many RU-vidrs (can I call myself that?) these things come together at the absolute last minute. There’s mistakes and imperfections. I greatly appreciate that you watch the whole video! That’s awesome. Certainly some topics are popular ones. Everything anker as long as it says anker.

At a guess, for product reviews in this category I would imagine that viewership peaks roughly aligned with major electronics sales holidays - ie the times of year that people are thinking to themselves "hey, maybe I should get a better charger, to go along with the other stuff I bought". So, maybe 3 key natural peaks in viewership per year, each peak smeared across the 3 to 7 weeks. How this mingles with the youtube algorithms adding a whole extra layer of "who the heck knows" to it, because life isn't nearly confusing enough already.

@@AllThingsOnePlace Not surprised about Anker, they do seem to be all the rage these days. Baseus are also very popular here in Poland, and I assume in other Eastern European countries as well. Then there's Apple - reviewing their ecosystem should attract some views I'm sure. Still, I think you have a great mix of brands and types. I've never tried dabbling in the RU-vidr lifestyle, but I assume that in the review business, you either have integrity, standards and a dedicated (if small) following, or you become a hype reviewer that might get a million views, but has the integrity and trust of a highway billboard.

Thanks!

Nice! Yeah, if you look around this charger has a safety listing from some manufacturers and not from others but it's all the same charger from Vina. It's not on the box for this particular brand for some reason. Thanks for sharing the many port use case!

Thanks! Yeah, I have another Car USB adapter video in the works, I did one a while ago. I haven't gone down the inverter rabbit hole yet but I put it on my list of video ideas.

@@AllThingsOnePlace Another category that came to mind was UPS units for computers from companies like APC, Amazon, CyberPower, and Eaton/Tripp Lite.

mmm, yeah, that is an interesting looking product. I expect that to be using a modified sine wave to get the footprint down. They are expensive compared to the conventional UPS. Also, I don't see anyone asking about replacement batteries. But it does look like they have safety approvals so that is good. I want to see a good DC side UPS.

Great points, hopefully more lightweight lithium ion battery backups come to market so I could have options

I am not sure, it could be something as simple as Vina offers two versions, one with a certified part (transformer for example) for $2 more and one with a non-certified part for a little less.

Yeah, this product is kind of a does mostly everything in one box, it doesn't appear bad, but for basic charging this is probably overkill.

Yes power stations....

Yeah, power stations has been on the list for a while. I need to figure out logistics with them, they are bigger, more power, I have an AC load but it isn't a good one, it's a box with switches and resistors, and of course much more expensive.

Yeah, the satechi 200w is that. With its 28v mode too. But that thing was off of the efficiency mark. This thing is so close. I’m wondering if a teardown is worth it. Maybe it is okay inside.

@@AllThingsOnePlace @ChargerLAB has teardowns of the ugreen 200w & many others without safety listings, could you give your opinions on the ugreen's internals? Thanks

@@CanuckTech Yeah, I didn't quite get enough detail to say good or bad, need to pause and take notes I guess, ha. From my own teardown of the 20 watt adapter, it looked mostly good.

mm yeah, that might be a whole other field to get into. Thanks for the suggestion.

Does it have a fan? There seems to be vents on the back side of the charger. Any coil whine?

@@CanuckTech no fan . no coil whine

Yeah, that is a different creation.

I also bought this - in Singapore it comes under the brand URVNS. I noticed immediately as well that the 3.1 port doesn't have PPS due to Samsung's charging indicator (green instead of the teal in 45w charging). The 260W one comes with wireless charging, extremely nifty.

@@CanuckTech Both this one being reviewed and the one I am talking about don't have a fan.

I think I just answered this. Matrix broken?

​@@AllThingsOnePlaceI actually sent the comment on the older upload first and wasn't sure if you'll still see it. I did get your reply on it, thank you so much and I hope they can still send you the X variant as well.

I've done a few so far. I have a lot to get going on though.

@@AllThingsOnePlace Would be awesome if you can review the JNS S20 (240W EPR) and JNS S33 (can go over 300W) powerbanks... they are probably the most advanced powerbanks I've seen with all independent ports and you provide your own 21700 batteries with no welding required. I can't find any powerbanks out there with what they can do. I have both of them on the way in the mail and pretty excited to check them out. There's a Russian channel review of the JNS S33 not in english but with auto generated captions, pls search for youtube video - MlXbr19M

It all comes down to voltages. If you need 5V then you can use a hub. If you need higher voltages then it gets trickier to find products that will work. PD passthrough or something. I've seen laptop hubs with one passthrough port then a bunch of 5V ports. Other than that I am not sure anything exists yet.

@@AllThingsOnePlace no worries, good to know! At this point I've just gotten the satechi 165w as it seems the best based on your testing. I'm hoping a good 200w+ one with more ports comes along at some point, but that seems my best option based on what I've seen of your tests. I'm planning to make a video documenting my setup at some point, and I really appreciate the information you've provided! I haven't found any other channel or website documenting these chargers in nearly as much detail, I really appreciate it!

mmhmm. I need to get some more power banks on the channel, and the portable power stations are probably a next level.

I don't mind the skipping PFC, that keeps power consumption low in idle states. Actually, it's good to turn it off if it's doing nothing, but then when it needs to be on just turn it on. I have an extreme example of that gone wrong though in an upcoming video, a very sick PFC circuit that uses maximum AC line power, then none. This adapter will probably require further investigation eventually. Tear it down maybe, but I know it's going to be difficult to get inside this thing so I will avoid that for as long as possible or never, ha.

Hello Tommy! With these power adapters getting larger, and outputting more power then they ever did before, and the increased heat generation, you'd think that they would install a fan in there. Or at the very least, a copper heat sink, for heat dissipation. There is a reason why computer CPU's, have an heat sink and fan on them to cool them, cause they get freaking hot, much like how these modern power adapters do. I think these companies need to stop protecting the status quoe, and start actually innovating. And one last thing, get their power adapters safety listed and properly certified too.

Well said, and ditto. I could take or leave a fan but it really depends on design. Although this one being physically large and only dissipating 13-16 watts full load, it can do the job without getting too hot.

Yeah, now that’s a prime time review suggestion. That I can hopefully get on the channel soon.

Yeah, I tried ordering GaN5 anything, they won't ship them, orders keep getting cancelled. Anyway, yeah looks like an interesting device if I can get one. The slim adapters are usually not great performance wise.

Which one? There are a lot of 100W videos, ha. But yeah, there are some products that may better work with Samsung devices, it is tricky because some things give up the super fast charging mode, PPS, fairly quickly, or have trouble negotiating, especially with more than one device plugged in.

Yeah, that's been on my to do list for a really long time.

I don't have a video on that. I've explained it briefly in other videos but yeah I should make a dedicated piece for the testing process.

Yeah, I have picked up a few of the smaller capacity power banks to check out.

Yeah, I have a megaohm meter with 1000V DC, they all pass that pretty easy but yeah I don't have a real hipot tester, earth leakage tester, or an insulation resistance tester. I'm sure I could find something on eBay. It would be fun to shake these things on a vibration table for like a day with random noise then see how bad they are.

Yeah, literally, power point defaults on most of the tables. I've noticed other channels using excel charts, also terrible, then yeah, big channels have real graphics, but they also have graphics departments. Competition is certainly real. Also, I talk WAY too fast. I actually slow all the speaking down, still crazy fast, but yeah that and add breaks. The videos will be a bit longer though and from experiments I've run that usually shortens watch time significantly, need to find balance. Thanks for the feedback though identifying the problem is step one. Doesn't help that these videos get mashed out at the absolute last minute in a mad dash to the finish line.

Yeah, I have a couple of chargers in that wattage range to check out.

haha, yeah this video is doing better, bigger number more better right? Thanks, yeah, so many USB cables...

I have ties to the industry but not directly employed by one. I get reports of these things breaking from various people occasionally, I don't think I've heard of the 737 breaking, sounds like an unusual failure mode too. Not the power supply that failed but the negotiation. Contact cleaner in the USB port? Just something to try, long shot.

Yeah, I have gone back and forth on that a few times. I usually do have links to some of the winners in the description but could add more description around them. Thanks for the suggestion.

Thanks. Yeah, it’s something different and in the end I agree with your conclusion.

haha, that name screams buy me doesn't it? It is probably one to check out. I have a few other higher wattage ones to look at as well. No idea how it will do, I always worry about overheating with those high wattage ones. I tested one 200 watt adapter that was a space heater and the one from this video was actually okay from that perspective. Anyway, I added it to the list.

I do a short bit on the display. It’s about 2% off on channel 1, not bad at all really. I should’ve spent more time on it. I have more footage of it. Maybe I will upload that as a short though. I do have a P.O. Box but I have yet to use it, ha. If you send the model I’ll try to get one.

@@AllThingsOnePlace Sounds good, I'm looking forward to the short. Also, the model is AUKEY Omnia 100W 2-Port PD Charger PA-B6. It is an older model from 2021~ and since Aukey was kicked off Amazon, they seem to have liquidated their existing inventory through other websites like Groupon (you'll find it for $10 on this site). I bought one and have been using it but am curious about its power capabilities and overall quality.

Yeah, I think I have that one here too. I also have a 300W one with a display. Should be interesting. I don't think any of these are 'safety listed' but still interesting to check out.

Ouch, that's a lot of devices. That's a big wish list and unfortunately I think a lot of the devices that make claims of being able to do all of that at once, don't. OR not for long at least before they break or overheat... So, it sounds like you need 1 USB C PD in, 1 USB C PD out (45 watts), plus go pro charging (5V-1A), and then another battery charger (assuming 5V-1A also). I'd almost go Anker 737 power bank then a USB A splitter. So, 100W PD in (charging and pass through), 45W PD out, then USB A with a splitter to the two camera battery chargers? Assuming each stays under 1 amp each at 5 volts. I think the Baseus Blade drops to PD 30W during passthrough mode, but does have two USB A ports. Note, if the camera is always powered via USB (no internal battery) it will shut off when you plug and unplug the power into the camera. So, not a hot swap solution.

@@AllThingsOnePlace Thanks for your reply have you come across through iniu 65 watt 25000 has some great reviews and recommendations?

@@chrissimonm1446 I have heard of it, but I haven't tested it. I know I have a few of INUI's power banks to review still. I think I have even increments though, 10k, 20k, and 30k.

Hi just been checking out the Anker as suggested looks good on paper, expensive. However they do not provide a great deal with the PB no cables and to get it to fast charge the unit you need to buy a 140 watt plug how these companies offer specs that you can't achieve without additional cost is beyond me 🙄🤣

Yeah, I am going to putting a video out in a couple weeks on my choices.

Yeah, that's been on the list for a while, I saw the teardown on chargerlab and it looks like it has good power architecture. I need to get the whole lineup in at some point. I just don't want to spend the money. Looking at around $600 after shipping to get the whole line on the bench, then looking at maybe $2 in ad revenue in a year. If the channel ever gets big enough, sometime after time ends, then I can get those on. When companies offer these for free they come with caveats like I basically can't make any part of the video the way I want. No one will pay a channel of 10k subs to make a video. Free thing exchange for video made exactly how the manufacturer wants. I don't know how other youtubers take product then say whatever they want and don't mark paid promotion, any offers I've seen come with a script and a no data allowed clause. Any free item is a paid promotion, that is also a sponsor.

Yes, I have it, it will make it eventually.

@@AllThingsOnePlace I'm so interested in its thermal performance, It's the only 200 Watts charger with active cooling

The power bank I think I reviewed. The screen flickered so bad, I had to turn the shutter speed down to like 2 fps to get stable footage of it. So I tried not to show it as much as possible. I did a usb cable with a display in it as part of one of the usb cables videos. No idea which one. I will have more adapters with displays though. I’ll probably post a short on the display on this one.

@@AllThingsOnePlace Thank you. BTW, nice equipment.

This video is actually the best performer in a long time of course. Goes to show still no idea what I am doing, which is good. Yeah, the power stations have been on the list for a while now. I need to figure out how to get stuff at no cost because power stations are substantially more expensive items and I am out of pocket to get anything on this channel. I have been offered a free one a couple times but with caveats of the company writes the content and reviews it. Seems like a lot of give for a battery in a box, ha.

Yeah, the mains cable is removeable so easy to use the proper cable instead of an adapter.

Yeah, in this case they did that, the first port is essentially isolated from the other four. But to do 3 USB C ports at 100W each totaling 300W is wasteful and probably will overheat in a small package. Most people, and most devices can get by with less than 30 watts. I have seen (and I have one) an adapter with all separate power ports. Mostly lower wattage, not useful though, also that thing is unquestionably cutting corners in the safety department, video coming soon.

@@AllThingsOnePlace What they really want to do is mislead people, then print a whole page of disclaimers and exceptions when you open the box at home.

NY, no where near the city.

haha, there's good ones, there's no such thing as perfect, as perfection is an impossible goal.

I just made a short video on that very phenomenon. ru-vid.comPpk9RtAKgbE?feature=share

I think that is just Qualcomm quick charge, and the USB A port will go up to 22.5 watts in that mode at 12 volts.

Here's a long and ramble, maybe at times coherent, reply! There are numerous camps on this front, some say earthing is bad in products and there's a better way to do everything some say more should be earthed, but in reality it comes down to whatever is written in the various safety standards which are intended to mitigate risk as much as financially viable. It depends on the product construction and how earth is connected. Metal bodied products are often required to be directly connected to earth, also products sensitive to buzzing, guitar amps for example, the input is directly connected to earth, meaning the guitar is directly connected to earth, meaning your body is earth referenced which helps quiet the noise from the instrument. There are other ways to do this of course. Faults before the product, for example, the earth line failing between the device and the earth electrode or bonding point, is a reason for less earthing, a fault in the earth system itself could cause the product to become live at line voltage in the case of a fault condition occurring. This is where a RCD or GFCI would be useful as it would detect the current returning through an alternate path, most likely your body, without a ground wire being present. Also, there are techniques to create low leakage power adapters, often at the cost of efficiency, but for sensitive applications these further separate the device from any mains connection, medical devices. So, that's the reason why not to have earth involved.

@@AllThingsOnePlace I don't think I get it. In the case of a failure between the device and the earth electrode or bonding point...you end up with a non-earthed device. So earthing it didn't make it more dangerous.

I know. I’m still working at it. I will probably drop this super high efficiency unit in as my new light power supply though. If I don’t tear it to bits.

Nice. Good to know. What’s the brand now? It’s made by vina as oem.

I hope that didn't affect performance lol​@@AllThingsOnePlace

@@AllThingsOnePlace I-Tikol

No idea how they'd do, but you know what you are getting and what you paid for it.

I bet they are all the same. The thing I'd look out for is the subtle price difference. Some may have a safety listing and some don't (like this one). Not sure which ones do. There is an Intertek record for the Vina product, yet this doesn't have it. So, I bet there is a component swap to cut price. No idea though. Performance wise I expect them all to be exactly the same.

Hmmm, so always review junk. Yeah, I started with something decent, that was a mistake. I did the same thing with power banks.. I guess others in tech are seeing drops also.

hah, banner specification, it has power factor correction... Someone watches my videos, haha. One thing I don't see, and no power factor correction can save you from the "does it have a safety listing" question. Anyway, yeah, I will check it out. It looks like a Baseus product.

@@AllThingsOnePlace It does look like it's Baseus but Baseus has a LED light on the side and a little bit different housing. Also this one has VI and ETL safety rating. Better something than nothing. I think it's worth checking out.

​@@AllThingsOnePlace I also noticed Baseus has 2 USB-A ports and Nomadiq has just 1. So I think these are not the same chargers.

@@darko1996x Yeah, I saw that too. Good to know it has a safety listing on it. I will pick one up.

@@AllThingsOnePlace Can't wait for your review sir!

It is all risk management. Lacking the listing presents a higher risk of damage to you the user, nothing is perfect but some do better than others. The safety standards may overreach a bit, a lot, but they do provide some pretty crucial tests that help keep the user safer, they don't test for operation or make the device good necessarily, just safer, again risk mitigation, not elimination. Some things that generally are included in safety work: electrical isolation from the mains to your body, weeding out potentially dodgy components that can cause shorts between you and the mains, temperature regulations, requirement of non-flammable plastics, consistent component choice, and many more things. Some that don't have a listing are good, some that don't are bad, real bad, the problem is with no listing you don't know.

Thanks.

Hi, fantastic channel! Keep up the great work!

Just bought the ACEFAST Z4 218w Gan charger , because it has a mode switch with fixed power profiles. I found out that with my ugreen 100w multiport charger because it negotiates power, when I have my steam deck charging and my iPad on 100% battery, just trickle charging, the steam deck keeps flashing white trying to negotiate power and won’t charge. It would be great if you could review this charger.

I'm all in on Gan 10.

Huh, interesting, and I know that happens from time to time, surprised they are even decreasing views for the big players. I noticed youtube pushing a lot more music, movies, and gaming content. I guess the general entertainment stuff sells better?

@@AllThingsOnePlace Must be! Or that audience has more click-thru on ads? The channels I've seen mention it are all technology-related.

I do open them up occasionally. In general the ones I've opened that don't have some kind of safety mark are terrifying, the ones that do are acceptable. This is a middle ground in that this manufacturer (vina) generally does have safety listings for the products but Otao chose not to use it? Interesting is the EU ones, which rarely have safety listings as they allow self declaration, the Hama and Cellular line had safety in mind in design, but the Essager wouldn't meet the requirements. Sometimes I don't show the teardown on camera but do it still. I don't tear all of them down. But anyway, it doesn't matter a whole lot as even the good ones of these are generally not good as they're all built down to a price, now that is a future video or several.

It's because it's a desktop adapter. Kind of expectation of you can plug it and unplug it without holding it down... None meet that criteria though.

I hope he was joking about the stand part, otherwise...I will be very shocked by the lack of common sense LOL

@@AllThingsOnePlace anything I have seen tends to need 2 hands unless it’s 3M’d down.. I’m struggling to connect the element of “desktop” with “one-handed” I agree with everything else you say though, I’ve watched a ton of your videos and I’ll be back for more!
