 Hey there YouTube Right, I wanna I've had one of these now for over six months And I made a video on this before but I'm a bit of a neophyte to all this and I Decided that I was gonna make another video because I'm more familiar with it now and I can tell you basically How this works? I mean, don't get me wrong. I'm not gonna go into The electron level or anything like that. I mean just as a just as the end user Who wants to have an idea of what this can what this can do for them? Let me tell you a bit back first It's a blue plastic case see-through as you can see and you can see Or the bits and pieces inside a big blobby bit there, which I'm sure probably there's a really good job. I Don't know what the parts are inside. I'm not even gonna bother trying to tell you and I can see this on the passes or resistors I see there, but that's not really what this is about. This is just about the functionality of it and What you get to see and what it is you buy Now this little gizmo is I'm sure this is a E. So it'd be K E W E I S I Care easy Care easy Okay, don't call me to the pronunciation as I don't know but it's a USB Charge display device I would say it gives you the volts amps milliwatt hour Down here and a time there I'll plug this back in and plug into this top this time As you can see, I've pressed the reset button Which is just on top of here and press it in hold it for a second. I'll do let it go and It resets everything back to zero Now of course the amps will be at zero unless there's something going through And the voltage is just indicating what the output of this is here So it's at 4.95 volts. We can say five volts The time part I was always I was first a little bit confused about how this worked and I used to plug my phone in or I still do on occasion plug my phone into this What would happen was once the phone had carried on I'd finish charging this would carry on counting I always used to think well, that's a bit of a pain really because You don't know then how long it took the phone's charge But thinking about it, which I did earlier on today. I thought to myself well because the phone is still powered on There's still gonna be little bits of charging going on. So of course this won't stop Because it hasn't finished it will only stop when you put something in That when it's finished charging it stops accepting more charge. Let's say a battery Battery on a little helicopter system Because the battery in here doesn't want to be overcharged And so when it is finished charging it will stop And that's what I've done Turn that around There we go Now This battery it seems has been charging for 16 minutes It's drawing 1.4 160 140 milliamps And we've got 43 milliamp hour of charge into the battery Since it started from a reset And I've got that connected into my HTC charger Just put it into a power strip like that And that comes across on this yellow wire Into the side My little helicopter there Which I don't know if any of yous have one of these but they're excellent fun Buy buy them for you know less than 15 pounds and they're great fun just to play around with So if I put that there and the camera doesn't go anywhere from me one you can see over here And you can see this continue now on this one when this finishes now when this has taken enough charge There'll be a little LED that will light up in here And I'm hoping that that's not going to be enough of a draw on this to keep that time going I'm hoping that that will shut the timer off. It may not Because of that LED But it indicates to me that the charge is finished and then I can you know Just give it a little bit of time for the battery to cool and then I can fly it But in the meantime We're back to this I mean this there's not a great deal to say about this You've got Input into USB and then you've got your output into USB On some of these not these particular ones. I've got another one Another one here. It's quite easy as I have done on occasion To get the USB to go in the wrong way round Okay, and it goes partway in and it Ships everything down, but it does come back to life. So that's a good thing Okay On this one, it's not that easy to put the USB in the wrong way round and so you don't fall into that little trap And you don't have those problems, but what I have noticed is But it's not just for this is with this entire thing is if you've got like your phone plugged in here and you knock this But it can happen as well if your phone is just plugged directly into here and you knock it And you lose pretty much all of the power going through These things don't like that. This doesn't like that. The only reason I know it happens on here is because if you just Come this way with me and look there That tells me the amperage being drawn for my batteries and so because This is connected to my batteries. I get to see them over there the power draw and Then I can see if I've knocked it. I can see it's gone down to nothing over there Otherwise it normally when my phones plugged in be around about two to three hundred milliamp power draw so You know, I've had these now over six months. It was 15th of December that I bought them and I played around played around I made a little video, but I made a big I made a mistake with how this works Because when it gets to 99 hours and 99 minutes It says full. I don't know why it would say full. I don't know why it wouldn't just start again, but it says full And so I thought you know, it's it's months down the line now It's there's been various things that I've bought from eBay that don't work after a while This still works and that one over there still works Which is great, and it would be lovely just to see if that actually stops the timer on that particular one When this is finished charging when the helicopters finish charging and that's something that I'm not gonna carry on rabbitting So you about now I'm gonna Pause the video and basically come back when that's finished and we'll see if it actually That's nice and easy to see The blinds again just so you can see the display It now says it's only drawing 10 million zero million up now So what I want to see now is that the timer stops so we don't want to see it go from You can't see that Let me see if I can just change that slightly for that to be different. This is one oh six And then what we don't want to do He's have it go to one oh seven That'll be quite disappointing because it's not taking any amps now My fingers are crossed because I really want this to show That this thing actually stops the timer When there's no current passing when there's no charge happening because then it actually makes Reasonable sense to have it there. Otherwise if it's just a Tick-tock timer for no reason. Well, there's the point. There's something else But you could put a power thing there for you know for those who would like to see a Quick calculation of the power rather than you know whip out a calculator or doing your head It's looking promising because this minute seems to be dragging on a little bit longer than I'm actually looking at the clock on my computer now just to Because if that goes past another minute then we can pretty much say that that does do that then but you have to have it where You know like on a like on a helicopter where it will age or as much power as what it needs And then it will shut off because it doesn't want the battery to overcharge except which has damaged the battery Bloody splendid if that is the case Okay, so my clock on my computer is now gone to 18 and we're still on six on there So before most definitely when it goes to 19, let's just have another look at what's going on here Still see that It's not the greatest. I mean if I put the light back on over the head overhead you can see better Because then we're going to see the then they do You still see the LED there. Yeah, I mean we can make out the LED now You know where you're looking is easy to see that the LED is there and we're still on 18 on my computer And even though as you can see I'm drawing off power. We still got 13 volts Going into these He says that and one goes up But you know what see what out now And I'm quite happy to say my computer is now gone to 19 and we are still on 106 so yes the timeout does stop when it stops The flow of power Because the power is no longer required and that gives a good indication of when something Is taking time to charge so now I know that it takes approximately one hour six minutes And my battery to charge in the helicopter And that's good because I know that before For some reason I thought it was like 25 30 minutes Maybe it was when I first got it, but I've thrown it around quite a lot since I first got it. So That's that's good. That's good. I'm happy with that That actually makes that particular device More helpful Then what I've anticipated it to be for the period of time I've had it which is you know over six months Since this 15th December 2015 brilliant Six months brilliant. Okay. Oh, I don't think we need to carry on with this. I think you can see now The device does work The timing system does work and it works quite well You can buy these on eBay UK sellers if you're in the UK for like eight pounds I bought both of mine for £4.48 From China. They didn't take that long to get here either But there is this issue that if you do wobble it around It does upset the electronics and it all or prefer to be Reconnected reset again. It's one of those things you'll have to Take into consideration If you are going to be charging your phone with it in search, don't expect the timer to give you a The indication of when it's finished charging because if your phone's on It won't finish charging of course because you're continuously using the power that I have in the phone on I Expect it will work now if the phone is actually powered off and charging But we can certainly see that when you're charging a device like this It does stop because we're still on 106 over there and I've been jibbering on again for minutes Hmm So yeah, that's a that's a thumbs up from me on these little devices because like I say they still work for starters And that timing device now does come into a practical usage Now even though I've just moved this and probably upset the balance a little time a bit with connections It's now gone to 20 milliamps and time has started again But I will imagine that that's just going to be until the battery goes There's a little checks and it goes hold on a minute. I am charged and shuts it back down again As you can see over there, it's flicking between 2010 I'm pretty sure that's gonna drop down again to zero, but we know that once it does drop down to zero That it does stop the timing Which is great, and of course, you know the next time I go to plug it in to try it again I can press the reset and as long as I don't move the wires around or upset anything while it's happening So the sensors don't try and pick up, you know, whether it's Charge not again. It will It will stop the timer when it's finished Okay, well, I hope that self-help so anybody out there was considering buying one of these whether they're actually a practical or not and I
