My respect to you bro I'm civil student still i understand everything.. Nice explanation 😋👍

Really good video, thanks! You saved me a lot of trouble! P.S. Nice equipment!

The voltage differential between the battery and what your trying to to step it down to in QC3 12v mode is too close together or the same. The voltage drop will be due to this most likely. In fact you can damage the module by having the step down voltage differentials too close together. You need at least 1 volt of difference, 1.5v to be safe. You should 100% charge your 12v battery so its at peak voltage or use a 14+ V psu, and do the test again on QC3 12v setting, likely you will have a different result.

Very informative and helpful, thanks

You have very in depth videos. If you work on your channel you can grow a lot. Try getting someone who can help you with videography and editing.

nice video thanks for making it.. you have solved my problem sir.....

Excellent job. Keep it up. Have a question. Is it possible to charge a laptop via this module using a solar panel ??. Thanks.

Please try connecting both the modules together to a 80-90 watt laptop power supply ( as tht is the most cheap and portable supply everyone will have). And then test both the USB on fast charging modes with loads on both of them. It will be very uselful as it will tell us that will a 80 watt laptop power supply work with 4 such modules at the same time. Thanks

Thanks bhai 🥰, i like this video a lot🥳

Very good video, in 1st test why not put voltmeter across battery, 2nd test using solar PV, put voltmeter at input terminal and why not plugin USB meter rather than lying on your table.

@gurribuy

in 1st test, i only had one pair of alligator clips, so i could not attach the voltmeter. In the second test, you are correct i should have shown the voltage of the solar panel and should have used the usb meter to show its output. Actually, that was the plan but, i forgot.

Sir tell me that can i use 1805 battery in parallel and then use booster module to increase volt up to 12v and then i connect this module to make power bank is there any problem or not

Is there any reverse polarity protection? Please inform.

yes, you can but remember that this module is a step down charger so, it will convert 6v into 5v and charge your phone.

Also, if your 6v panel outputs very small current your phone will take much longer to charge.
