I've just bought one of these testers it's very useful. Don't forget the power bank quotes 5000mah at 3.7 volts but the meter is measuring milliamp hours at 5 volts. I've found it's more useful to use the watt hour total. I'm not sure if the micro USB dongle is anything special because I find with USB C power delivery systems the power is off until some current is drawn to activate it. If the port is already on the dongle is not needed.

Awesome 😊

That could be why one of my scanners doesn't receive anything.

Have a look on the video description if you are looking for a new handheld amateur radio tranceiver!

😢😢😢

Dongle needs for usb out port..not for type c protocol...just plug dongle for charge phone or tablet without micro usb cable

Good day Sir, I was wondering if I may ask, are you able to fit this unit to, say, a 12V 2A power supply and run the output at 24V 0.63A? I understand it is a buck converter, I thought perhaps it might operate as a buck-boost? Many thanks!

Well, I have not used Nmh batteries for some time now. I started to use lithium batteries and have better luck with them. When I did use those batteries for about a 15 year period, I found that none of them, cheap or expensive lasted more than about 30-50 charges before they lost significant capacity. This was also over several years, so time has a lot to do with it also. I have also found that many items do not like these cells due to the lower voltage. They do have a very high discharge rate, so toys that draw a lot of power actually work much better, such as rc cars over alkaline batteries. Most people hate them in flashlights as they start out kinda dim in the first place. The lithium cells put out full 1.5 volts over full to empty making it more difficult to tell when they are at end of charge because they go from working like new to suddenly shutting off with no way to see remaining charge. I actually switched back to Alkaline cells after nearly 20 years because they are a pain. Almost anything I buy now, I choose for it have internal rechargable lithium built in using USB.

I prefer to wash the filter with petrol to remove debris and accumulated dirt . And flow the solvent material from inside out for better cleaning . Then a final dip in 50 50 mix of oil and diesel before installation . I also tend to have a prefilter made of scrubbing pad like scotch brite at the entrance of air intake rubber and that also helps retain some particulates

Thks for your Exllente video I have a Vespa lx 50 my indicator working normal when the scooter is running when I break start flashing quickly any help please thank you 😮

where did you find these protective rails with footpegs? looking real nice

What's the maximum input current for the XL4015? And what is the ideal input current?

Love the Big Clive nod with your desk top!

it would had been better to say "stated amounts of re-charges " instead as you don´t really know how fast the cells decline over time and actual cycles. cheaper cells typically wear our faster but I seen branded batteries lose a lot of capacity quite fast too. to get real numbers the cells would need to be in heavy service for a year or two to show it´s actual value

Thank you! Trying to work on this printer late at night without waking my wife sleeping in the next room lol.

Thanks so much for your thorough troubleshooting steps. I had the exact same symptoms and it turned out to be the same issue you found in part 2, a bad bulb socket. I will be donating right now!

Thank you for the explanation on the jets I was a little confused that the top of the jets sit in the air rather than fuel but makes sense now. Wellness bath hahaha I will think of that every time I clean jets now!

So, to know the real capacity of any powerbank, multiply the nominal capacity by a factor of 0.85. 20000 * 0.85 = 17000 mAh 10000 * 0.85 = 8500 mAh 5000 * 0.85 = 4250 mAh

wo sitzt das Blinker Relais "PX80" ?? where is the turn signal relay located?

Lieve help, beter eerst de bougie controleren en zodanig de nieuwe bougie nemen. bedankt voor de filmpje.

Very informative

Sehr gut und genau erklärt Dankeschön

Dear Sir, I love some of your videos, but the reason you only have 21 views after 18 hours is because almost NO ONE has almost HALF AN HOUR to watch you yap for 27 minutes about a topic that WOULD be worth watching if i was under 5 mins. But few people have 27 mins. to find out what is, and isn't salvageable from a dead power supply. BREVITY is the key my friend! I know you might love to hear yourself yap, and you DO have a pleasant voice to listen to, but you're a yapper, and most people don't have half an hour to listen to you yap about something that would be very watchable and very interesting if it was less than 5 minutes. #yapper

AFTERMATH: I had to shorten the screw, switch the two nuts to just 1 nut, secured with screw locking agent, because otherwise the connection is too long, and so the rubber cap rubs against the engine!!!

Just bought a couple of these and turning the screws does absolutely nothing. Output voltage is the same as input Would think maybe one was a dud, damaged in post, but both of them?

Nice, I have the same problem on my PX150, so time to try the same steps!

Should be noted that the 5,000mah is the cell at 3.7, not output voltage. So the Wh reading should be used. If you correct for the voltage though it’s 3,416mah which is 68% efficiency, more than half but it’s alright I guess

You could probably put pegs on the stands and a negative hole on the bracket. Would make it easier to assemble.

Get yourself a NGK spark plug cap makes things along quicker.

How do you solve stringing issues?

Your temperature drift test doesn't make much sense, because not only are you cooling to an extreme that won't normally be seen (that low) but also because you were cooling the wrong chip, as the LM358 doesn't pass the current, isn't going to heat up nearly as much as the XL4015, or the diode which also has temperature increase and drift based on current. Even so, I can appreciate cooling it to whatever ambient temp it will actually be used in, in order to most accurately adjust it before use.

I enjoyed this video. Nice ti see maintemance close up.

Te funciono ? No hace falta hacer ningún tipo de modificación ? Yo tengo una vespa 125 PX

Hola ! Crees que se pueden modificar los parametros de los BMS de las baterias de litio ( li-ion , LFP...etc ) ? Todos permiten cargar y descargar demasiado las baterias y resulta que las degrada rapidamente , por ejemplo las li-ion es mejor que corte la carga/descarga a 4-3,5V , las lifepo4 que las cargue hasta 3,5V y descargue hasta 3V , o hacer que sea regulable De serie incluso superan los parametros maximos de las baterias! Seria muu util explicar esso para mucha gente . Gracias !!!

That 100~105 hz ripple could be due to ripple from your power supply. Do you live where your mains frequency is 50 Hz? If so, that's more than likely mains ripple from the bridge rectifier inside your power supply you used for testing the board. It may not have been the buck regulator entirely. Great video btw as well.

what is the scream at 7:47?

What does he use to clean the jets? the sound drops when he mentions it, and you cant hear what he said

Na toll. Mir haben sie gerade ein MTB aus dem eigenen Innenhof eines Mehrfamilienhauses geklaut was genau mit dem Schloss gesichert war.

why do you oil the filter?mess pls

i seem to have a bad vibration when. i apply front break.a shudder.? what could it be please.great video

Very nice Video. Thank you for the tutorial. I actually tried something similar myself and the step to convert a photo to an STL file was more difficult and did not have nice accuracy. I just checked and you could import .svg files in Fusion 360 (free version) and you could extrude the logo very easy too.

I'm just beginner. So should I add 680uf from now on if I need to connect this xl4015 to any device?

Thanks for the informative video. What is the tool you’re using the adjust the fuel/air mix screw? Did you buy it or make it yourself?

Great video
