its not a good idea... from 5v 2a charger you can not charge a 12v /7a/9a battery .charging amp would be less then 1 amp .i think max output will be around 12-14v/ 500-600 mili amp .
Yes, it will work - theoretically. This module does not limit the charging current. A discharged 12V battery will initially draw a lot of current. Let's only calculate 1 amp (which is far too low!). 14V / 1A means 5V / 2.8A (we have 100% efficiency 😁 ). So we pull just under 3A from the 2A USB charger. Starting->protective shutdown->starting->protective shutdown... will definitely be funny 😇How long will it take to load? On the other hand, if we use a more powerful USB charger, we will get a thermal problem with the DC-DC module. MT3608 has 4A switching current limit - means 2A at input(!) - and that only with sufficient cooling and not permanently. Take a current-controllable module or a even better, a suitable charger.
Only 20 watt 12 volt lamp serial connection. Ready to limit current
@@malisagbili Please calculate the current limit of a 20W / 12V light bulb yourself or measure it in practice. On 14 volt side it is not enough and on 5 volt side it is too much. 🤔
@@wernerpeter9706 My power supply 14 volt 5 Amper. For battery charge; 600 mA with 20 watt car bulb, 1700 mA with 60 watt car bulb (serial connection).
@@malisagbili That's exactly what I mean - the 20W 12V light bulb between the USB power supply and the DC converter is limited to +- 500 mA - you charge the 12V battery with about 150 mA . The 20W 12V light bulb between the DC converter and 12V battery is limited to 1.5-1.8A - for this the USB charger would have to be able to deliver at least 4.5A. But it can't and the converter wouldn't be able to handle it either.
You have to include the DC-DC converter in the calculation, it has to increase the voltage from 5V to 14V and the power supply can only deliver 2A on the 5V side. More than 10 watts are not available.
@@wernerpeter9706 We think the same things. The 20 watt bulb you will connect between the negative or positive pole of the battery will be charged with 600 mA, that is, 8.5 watts (14*.6). 5volt 2 amp adapter can do this job.
Thanks ❤
Hello, engineer, you used an interesting idea, you created a spark in my mind with this work, you are great
I'm so glad I could give you some ideas.
@@ZAFERYILDIZ52One question, when I finished charging the battery and did not remove the mt3608, would the battery voltage go to the output of the mt3608, what would happen there? Would the module be damaged? My project is to charge an 8.4v battery with its respective 2s bms using a 5 volt usb and raise the voltage with the mt3608 but everything will be soldered and that is my doubt
Thanks bro ❤❤❤
Boa noite!? Qual é o modelo do seu multímetro?? Parabéns 👏👏👏👏 você é fera 😳🤜🤛👏👏👏 amos de mais seus vídeos 😊
Eline saglik ustam 1 milyona az kaldi❤
inaşşah kardeşim teşekkürler
Con un elevador de tensión, carga lenta y tranquila, gracias por tantas ideas asequibles!!
La carga llevará mucho tiempo pero eventualmente se cargará.
ขอบคุณมากครับ
elinize sağlık
çok teşekkür ederim
Merhabalar güzel bir çalışma olmuş Teşekkür ederim. Sormak istediğim bir şey var 7.2v 2280 mAh li-on pil ile çalışan fotoğraf makinemi sürekli ve sağlıklı çalışması için kaç volt ve amperlik bir adaptör bağlamalıyım? Ve direk bağlayabilir miyim yoksa arada nasıl bir devre getekir?
Brother, Mobile charger (adaptor) 5v 2 amp if we increased the voltage from 5 v to 14 volt the current (amp 2amp) will remain same or current will decreased ???
After the conversion, no more power can come out than goes in. 5V * 2A = 10 watts, which is the maximum power at the input of the DC-DC converter. 10 Watt / 14V = 0.7A, these are the max amps at the output, at 100% efficiency. Efficiency should be between 80 and 90% (max). So at 14V about 0.6 amps at the output.
current drops charging current is around 700 ma / 1 A
@@ZAFERYILDIZ52 thank you bro for your reply 👍
Use 500mA-1A phone charger, slow charge is better
Min 2 A Charger
At output you will get 150-200ma
The output current depends on the payload. AFAIK, the step-up module used by author supports loads up to 3A.
Recommended charging current of that battery is 0.2C, so 0.2*7Ah=1,4A. 14V*1,4A makes almost 20W of power. But as it was mentioned, much more safely to use lower current rates, and limit it to 0.7-1A (12w)
Your charger is mostly either 5v/1a (5w) or 5v/2a (10w). So, both are suitable, but 2a charger is more prefered, as it provides more power, which is approaching to recommended values.
Also don't forget, that step-up doesn't have 100% efficiency, so there will be some power losses due to step-up conversion.
Conclusion: 5v/2a is much better.
@@MasterGallery yes right
I tried this joke, maybe a year or so ago with this module and later also with more powerful ones that aliexpress advertises for 4 amps, but it just doesn't work because the module heats up so much that it almost burns out, I tried it with a usb charger that has 0.5 amps and the 5V voltage is so insanely hot that I rather cut it off, but they were bought for exactly the same reasons as you are now promoting this video
Minimum requirements 14v 1.3A
Merhaba size öğrenci olarak kafama takılan soruyu soracağım
Transistor ile anahtarı ters nasıl yapabilirim yani anahtar kapalı durumda led yanmayacak anahtar açıldığında lef yanacak bunu çok merak ediyorum yapamadım bide siz bana söylernisiniz lütfen
NPN bir transistörü Base ile Emiter arasından tetiklersen enerji geçirmez Collector ve base arasından tetiklersen iletim gerçekleşir. kısaca cevap E ve B arasına anahtar koymak 220r direnç ile anahtardan geçen akımı sınırlayın akımı sınırlayın
@@ZAFERYILDIZ52 teşekkürler kanalınızı takip ediyorum inşallah kanalınız büyür
Keren, ada saja idenya 👍👍👍👍
Terima kasih
Зачем нам вольтаж мониторить всю зарядку. Самое интересное на силу тока смотреть. Ерунда!
Среднестатистическому зрителю без технических знаний гораздо понятней будет демонстрация эффекта работы зарядки в виде возросшего напряжения, а не падающего тока 😊
.
MT 3608 DC DC Booster
I max - 2A
U in- 2-24V
Uout max-28V
Всё будет работать.
Однако микросхема не очень надежная и будет при максимальном токе сильно греться.
При низкой стоимости модули обладают рядом достоинств. Конечно же, недостатки тоже есть: отсутствие защиты от КЗ и перегрузки по выходу.
При полностью разряженном аккумуляторе проблем нет, но емкость аккумулятора составляет примерно 60%
Use that metode and you will need 1years to waiting full

adaptör 5 volt 2 amper 5x2= 10 watt. Boostconverter 14 volta yükseltiyor. 10watt bölü 14 volt = 0,71 amper saat eder. batarya 9 amper saat olduğuna göre. 9 / 0,71 = 12.67 saat te bataryayı doldurması gerekiyor. ama videoda 15 saat te doldurduğunu görüyoruz. peki neden 15 saat sürdü. ilk aklıma gelen adaptörün 2 amper vermeyeceğini düşündüm. tekrar videoya baktım huawei marka kaliteli bir adaptör 2 amper veriyordur. boosterın çalışması için gereken enerjinin bu hesabı etkilemeyecek kadar küçük olacağını düşünüyorum. Belkide ben yanlış hesaplamışımdır. ustam sizin düşüncelerinizi nedir?
Вы не учли КПД повышающего преобразователя. Плюс неизбежные потери на нагрев электролита. Именно поэтому в инструкции по зарядке АКБ указано ток зарядки 10 процентов от ёмкости при цикле заряда в 12 часов...
😂
Teşekkür ederim
çekilen akım sabit degildir ayrıca modül ısındığı için akım başlangıçta daha da aşagıya düşebilir ve hedefe yaklaşyıkça daha verim artar aslında bir sogutucu ekleyerek daha verimlikullanım mümkün

Well why not, easy for an engineer with a soldering iron etc. Hardly worth making a video about it!
keep it in the back of your mind
4 കൊല്ലം മുൻപ് ഞാൻ ഇത് ചെയ്തു തുടങ്ങി. യാതൊരു കുഴപ്പവും ഇല്ല.
ചിലർ അവകാശപ്പെടുന്നതുപോലെ ഇത് തീർച്ചയായും വലിയ കാര്യമല്ല.
🤲❤👍🇹🇷👍
what i can hope for better ampere also from this booster????? Is it a joke???

Не смеши....ток зарядки 2.7А... твой...зарядник сдохнет через час....😂😂😂😂
15 часов😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
how?
Однако сам рассмешил... Сначала матчасть выучи.
Ну как минимум ты не обратил внимание, что заряжал он не глубоко разряженный аккум, а, скажем, заряженный на процентов 60. И нет, не сдохнет этот модуль от 2.7А. Впрочем, радиатор бы туда не лишне поставить...
И да, с ростом напряжения на аккумуляторе, снижается разница потенциалов на модуле и аккуме, а значит и потребляемый аккумом ток. Когда потенциалы сравняются, ток упадет практически до нуля. Т.е. чем ближе к цели, тем менее будет греться модуль.
Вообще-то номинал модуля три Ампера. Конечно лучше поставить радиатор Ил модуль на 5 Ампер. Здесь важна сама идея. Зарядить до двенадцати вольт если есть что-то из низковольтного.
Хотя в домашних условиях смысла особого нет.
Заряжается долго, но заряжается. Вы можете заряжать его несколько дней с помощью хорошего зарядного устройства.
