Okay, so this is squarely in the weird territory. You know me, I'm always trying to encourage the ambitious, the strange, the weird. This is what this is: bone cooler D DV die. This is a Weili do special, as usual, a phone cooler, an active phone fan cooler for the hardcore smartphone users, likely gamers, I would guess. 5,000 RPM semiconductor refrigeration. If that doesn't get your juices flowing, I don't know what does. The cooling effect is two to three degrees, which not only ensures the cooling effect of the mobile phone but also prevents the phone from freezing. Freezing? Wow. See, this is like a marketplace I don't even know about, and meanwhile, it's probably booming in China. The heat dissipation effect is awesome, definitely a winner among all the mobile phone coolers. That's like a Donald Trump type of sentence right now: a definitely effective and awesome cooler for all the needs necessary. There you go. Now, Will told me to go easy on it. He said it's a prototype. I don't really know how to go easy, so I'm sorry about that. Well, oh, it looks so cool. It reminds me of when you shave your head, you know, the clippers power light. I don't know why it has a light frozen shell. I see the little tiny fan in there, and then there's some sort of conductive pad designed to pull heat away. This is spring-loaded, so it could fit various devices. I'll try it out on a couple. There is a micro USB charge cable to charge that thing up. Will, come, come, you in the show? I'm trying to do a video. You're over there screaming and yelling. This is the biggest release of 2019 so far. Okay, there was a keynote, and they hired Tim Cook for this. You know, with live streaming, it could potentially get hot as well. Your phone, your big live stream, maybe? No, no, not at all. Who knew? What about vlogging? Well, there's one thing we should mention: here, everything has air conditioning. Like, everywhere you go is air conditioning. Yeah, boy, like, I've been places, dude. I've been around your world, pretty fortunate. I was in China, I was in India, and I'm telling you, it's not air conditioning everywhere you go. If you leave your phone on the dash, you know how hot it can get. Oh yeah, it can cook. Yeah, cook an egg on it, definitely. So, as far as eggs go, how do you like to eat them? Uh, I like some over easy sometimes. Scrambled? You ever poached? Poached is great. You poached? Further? The noodles? Wow, look at you, you're a chef. Yeah, what about you? It's mostly a lazy thing. I mostly just scramble it. I'll put a little bit of steak spice. No, no, no, no, not barbecue sauce, steak spice. Like, you know, it's a keg. You've got like the pepper. Oh yeah, it's like a strong spice. Yeah, okay, paprika. And without this, we are typically cooking just right on top of our smartphones. Exactly. With it, now we don't have to do that anymore. You can actually use our stove instead. It is normal for the product to produce a small amount of steam or water drop during operation. Mmm, condensation. All right, so I have a OnePlus 7 Pro over here. Goes like this. That's your look right there. Look at you, you're ready for a gaming session right now. You know, I blew my mind when we were in China. Everybody talking about competitive gaming on phones. Mmm, for rural tournaments, MLG status, but on phones. Do we have any juice going on here? I think we gotta plug it in. No battery? It's a power core, no battery. You would probably have your phone powered because if that thing goes off, you got a million dollars on the line. Well, they don't want dangling the turtle. Let's do the stress test without and then with. Touch, go. Touch? Yeah, it's very, very cool. When you touch the side of your freezer, it's very... How often do you do that? Every day. Whoa, it's icy. So, what we're doing over here, I'm running a stress test on N22, and I'm running a stress test on what? Well, and to, to the stress test is happening without the cooling factor involved. After that's finished, I'm gonna run it with the cooling unit, and we'll see if there's any difference. All right, so the stress test has been completed on here. The one I'm interested in: battery temperature. You see it scaled up over the course of the stress test to around 40 Celsius by the end of it. So that's interesting. That's the area we're gonna be looking at. I would personally be happy just to see a lower battery temperature than 40 Celsius by the end of it. Yeah, I think that gonna make a difference. I think that would be cool. Anyway, let's go ahead. Let's run this test again with the cooler on, and we'll come back in a short moment when these cookies are baked. 96-97. Yeah, there we go. Okay, what do we got? Battery temperature never quite hit 40, but it was right there, like 39. Well, it made a little bit of a difference, a little bit. Also, the disadvantage on the second test being the fact that the device was already sort of heated up, so you gotta keep that in mind. You're a degree cooler, whatever that means to you. But as it says in the box, there are limitations to this type of tech and how cold it can actually be. It works a little bit. Who's it for? I mean, it's pretty heavy-duty. It's for the hardcore, for the big dogs. It's for the oldest types. If your phone has like no water resistance, you actually get some water droplets on there. I don't know. It's a cool-looking thing. It's a funny little contraption. If you think you need this, you, you're a certain person. Like, you already know probably. All right, exactly what I need. It's called the cooler, and it's out of control. [Music]

the mobile phone cooler that's like that's like a Donald Trump type of sentence right now a definitely effective and awesome cooler for all the needs necessary there you go now will told me to go easy on it he said it's a prototype I don't really
01:07
Speaker A
know how to go easy so I'm sorry about that well oh it looks so cool I remind you like when you shave your head you know the Clippers power light I don't know why it has a light frozen shell I
01:23

see the little tiny fan in there and then there's some sort of conductive pad des gonna pull heat away and this is spring-loaded so it could fit various devices I'll try it out on a couple there is a micro USB charge cable to
01:37
Speaker A
charge that thing up will come come you in the show I'm trying to do a video you're over there screaming and yelling this is the biggest release of 2019 so far okay there was a keynote and they hired Tim Cook for this you know with
01:52
Speaker A
live streaming it could potentially get hot as well your phone your big live stream maybe no no not at all who knew what about vlogging well there's one thing we should mention like here everything has air conditioning like
02:07
Speaker A
everywhere you go is air conditioning yeah boy like I've been places dude I've been around your world pretty fortunate I was in China I was in India and I'm telling you it's not air conditioning everywhere you go if you

03:51
Speaker A
on the line well they don't want dangling the turtle let's do the stress test with out and then with touch go touch yeah it's very very cool when you touch the side of your freezer it's very how often you do that every
04:08
Speaker A
day whoa it's icy so what we're doing over here I'm running a stress test on n22 and I'm running a stress test on what well and to to the stress test is happening without the cooling factor involved after that's finished I'm gonna
04:28
Speaker A
run it with the cooling unit and we'll see if there's any difference all right so the stress test has been completed on here list the one I'm interested in battery temperature you see it scaled up over the course of the stress test to
04:42
Speaker A
around 40 Celsius by the end of it so that's interesting that's that's the area we're gonna be looking at I would personally be happy just to see a lower battery temperature than 40 Celsius by the end of it yeah I think that gonna
04:55
Speaker A
make a difference I think that would be cool anyway let's go ahead let's run this test again with the cooler on and we'll come back in a short moment when these cookies are baked 96-97 yeah there we go okay what do we got
05:09
Speaker A
battery temperature never quite hit 40 but it was right there like 39 well it made a little bit of a difference a little bit also the disadvantage on the second test being the fact that the device was already sort of heated up so
05:32
Speaker A
you got to keep that in mind you're a degree cooler whatever that means to you but as it says in the Box there are limitations to this type of tech and how cold it can actually be it works a little bit who's it for I mean
05:45
Speaker A
it's pretty heavy-duty it's for the hard core for the big dogs it's for the oldest types if your phone has like no water resistance you actually get some water droplets on there I don't know it's a cool-looking thing it's a funny
