00:00Hello everyone, I have here DC2DC boost module with a 2 to 24 volts input and 5 to 28 volts
00:12output at 2 amp max.
00:15We are going to see what this little guy can do and since I bought 10 of these I will
00:23try to destroy one of them and see if it has any safety mechanisms inside.
00:31You can either power this module with a USB-C power supply and this will output, let me show you,
00:45right now we have an input of 5.2 volts and we have an output of 15 volts.
01:01Since this is a boost module, it's not a back boost, this can only increase the input voltage, so you
01:10cannot adjust the potentiometer to reduce your input.
01:15Let me show you, see at the voltmeter, by turning this clockwise,
01:25you can see we can go from 5 volts input to 28 output.
01:32Of course we cannot expect from 5 volts to output 28 at 2 amps, that would be impossible, but it
01:44is still impressive that we can go so high.
01:48Ok, I am going to disconnect the USB-C, or no, let's see how much amps it can output with
02:00this power supply.
02:02We are at 20 volts, let's go at 10.
02:09We have twice the boost and we have about 10, or exactly 10.
02:19Let's bring my load and see what it can do.
02:25And here is my little friend.
02:35So we remove the voltmeter and let's see what we can get from this guy.
02:42Ok, we can see at the load that we are at 10 volts and 1 amp.
02:50So we have twice the boost from 5 to 10.
02:54And we are asking 1 amp. Let's see. Let's keep an eye on the voltage.
03:03Quite impressive.
03:07And it is getting quite hot, but we have many of them, so we don't worry about burning any of
03:14these modules.
03:15Let's go to 2 amps straight away.
03:23And we dropped from 10 volts to 4.
03:30And...
03:31Ow.
03:33Ok.
03:38It triggered the lower than 3.1 volts that I've put.
03:46Ok, let's go to...
03:47And this is really hot here.
03:50Let's power this module from a better power supply with higher voltage.
04:02I have the power supply set at 15 volts and we are boosting at 24.
04:10Let's see if we can do 1 amp at first.
04:17Let's see.
04:24And we are at 1 amp and we dropped to 23.3 volts.
04:33Let me get the thermal camera and see what's going on.
04:40And we have the chip and the diode at around 60...
04:48The diode is at around 62 celsius.
04:54So we are at 66 celsius.
05:00At 1 amp.
05:0267 and rising.
05:04So this module definitely needs a cooling method.
05:11Either a small fan or an aluminum heatsink.
05:17Let's see if by dropping the boost it will change anything.
05:25So let's drop to 20 volts.
05:3220 volts.
05:32And we are at 73.
05:3720 volts and 1 amp.
05:42So...
05:42I mean I'm going to raise the current to 2.
05:47And we are at 2 amps, you see.
05:51And the temperature is at 105, 106 celsius.
06:01This is getting really hot.
06:05Over 110, yeah.
06:09So we are...
06:11We are asking a lot from this guy now.
06:15Even though the boost isn't that much.
06:18From 15 to...
06:2120.
06:22But 2 amps.
06:25Without any cooling this will probably fail soon.
06:31So this is it.
06:35Let's see if we can somehow destroy this by raising the current.
06:40Or if we are going to trigger any safety.
06:44Okay, I'm raising the current to 4.
06:50And we are at 183 celsius right now.
06:55And it is starting to smell.
07:01That burning electronic smell.
07:04200 celsius.
07:06It is starting to really smell.
07:10Let me drop the amperage.
07:14We are now at 135 celsius.
07:19And dropping.
07:21But we dropped to 1 amp.
07:24Which the device says...
07:26That it can do up to 2.
07:29Let's go...
07:31And reduce the boost even more.
07:33And see...
07:37Oh...
07:37We are at 17 volts.
07:42And 1 amp.
07:44At 85 celsius.
07:46Let's go to 2 amps.
07:50And we started raising again.
07:54Yeah, I wouldn't use it over 1 amp.
07:59Especially without very good cooling.
08:02Let's drop to 1 again.
08:0310.
08:06Yeah, around 1 amp.
08:08This device works...
08:09Fine.
08:13And with...
08:15Good cooling.
08:17It will be even better.
08:19Let's raise the boost to 25...
08:2224.
08:24We are at...
08:2624 volts...
08:28volts boost.
08:30From 15.
08:34At 1 amp.
08:37At 1 amp.
08:37And we are at 80...
08:39Around 82 celsius.
08:42So this is basically a device...
08:44Where you can boost from...
08:45Low voltage to...
08:473 or 4 times the voltage.
08:49But with...
08:51Quite low amps.
08:54Just to keep it safe.
08:56So that's it guys for today.
09:00Let me know if you...
09:01Liked it and...
09:03See you on the next one.
09:05Bye.
