I was suppose to buy this. Thank you for your review. Really help me avoid a possible disaster.

[tech.]

0:41 + output terminal and heat sink on one side are connected.
The heat sink on the opposite side is connected to the ground side.
When the maximum voltage is generated, high voltage is applied to both heat sinks.
Risk of electric shock and fire.

0:41 +出力端子と片側の放熱板が接続されている。
反対側の放熱板はアース側に接続されている。

感電と火災の危険がある。

Thanks for video. If you replace nce8290 with the 75N75 MOSFET would that fix/improve it? Also why do you get shocked between heatsinks? can that be fixed easily?

mine came broken it doesn t do anythinbg no matter how u turn both potentiometer output voltage is awlays equal to input voltage with and without load!! ... do u know what would be the problem mybe post the circuit diagram ? thanks

[casper]

What ga wire are you using to feed the device? It looks like you're using super tiny 28ga steel wire. Im no expert but what if you used a larger gauge copper wire? Would it still cause these problems? I have one of these I gor for .99cents so I can't really complain unless it doesn't work at all but I am curious

[getbettersoonbroo]

Is it good to charge 48v scooter battery with MPPT from solar input?

[Eksands]

current adjust never works for me. I ordered 3 different already and I get no output difference when I rotate the current limit screw

[ruelbustillos]

Is this can be used in 24v 140watts mini ricecooker?

[FernandoSouzadroid]

Hello, I use a step down for lamps, in total they consume a maximum of 8a, but the charge controller varies the input voltage between 14.4 and 12.5, so it reaches 11v and the lamps become weak, I wanted to add this step up the video before step down, and raise the voltage to 16v, does this work?

[De-twby]

Can you recommend any other unit which I can buy with similar spec and short circuit protection. Thanks

[AkiiLesy]

Thanks for the video, what if i don't need the Constant current, current may depend on the load, thanks

[murraymadness]

I have some bad ones. I have another one that was working fine, but after turning the current adjust all the way it now does not work right. I checked with the other one I have that works,
and the pot on the bad one shows 3.2k ohms between end terminals, whereas my good one shows 300ohms. So I think pot is broken.

Make sure the sorce is not flactuating for stable supply and current and also make sure that the circuit is clean.
Screw wire instead of clup and small solid tin wire.

[deanp]

Came here after it broke my voltage regulator. The aim was to step up my 48v supply to 53.3. Honestly it had a mind of its own, voltage was not stable at all. Ranging for 30 to 70+ spikes.

[kamranbatteryservice]

Same situations, I am facing too !
current boost adjustment is use less and dropping voltage on load .
unfortunately I saw your video after buying this product

[hamasmalik]

I want to ask how many maximum amperes I can get from this at
12v input and 24v output = ?
19v input and 24v output = ?

[emmanuelpeter]

Is only a boost converter or also a buck converter

[moturcu]

Isn't this just for battery charging we can't use it in a motor for example?

[mhdgs]

I want to buy it to charge a 50 volt capacitor bank for a coil gun I'm making, I've made a zvs driver to charge the capacitors and I ended up blowing the mosfets. I'm thinking of buying this converter because it gives me a bit more room to charge them to 60 volts rather than 50, the capacitors can handle 50+15 volt over charge. The converter will. Be ran at 55volts most likely at a current of 2 amps, is it a good idea to buy it,

[aztrader]

I have 12v 5a as input, the output voltage is only 1.16v. How is that possible. The potentiometer is not working at all. I guess I got a bad one. Damn it
