DIY USB Load Tester

[@luise.p.r9248]

good video, I have a query ........ the load resistors are in contact with the wires, this I do not think is advisable, since the resistances are heated and can burn the cables. regards

[@LahisTechLT]

Thank you, i did that to make it looks smaller and compact. if we are able to test the loads & voltages between 1-2 minutes it will be fine.

Why did it show 0.90 amps in the car charge? but when I connected the phone it was 1.57 amps ???

[@LahisTechLT]

No it was same check at 10.18 and 11.10 --- phone charger is 1A output and the car charger is 2A output so more current draw from the car charger.

[@dyatlovpass537]

@@LahisTechLT no I'm talking about car charger...draws 0.90 amps when both resistors are active.. but...1.57 amps when phone is added ...why ??? i'm turkish my english may be bad sorry :'/

[@LahisTechLT]

@@dyatlovpass537 Yeah, that's what i'was talking about. The load tester shows 0.90A (two load resistors ON) without plugging the phone in it. check it once again at 11.08; it's 1.54A when the phone is connected (two load resistors ON). Don't worry about English I can understand you. Check 11.08 Exactly!!!

@@LahisTechLT auhh.... Sorry.. sorry... Why is 0.90 a when both resistances are active? why not 2.0 amps ???

superb job

[@imtaufiqmehedi]

Can i use 20w 100 ohm???

[@LahisTechLT]

Can't

[@imtaufiqmehedi]

4.7 ohm 10w? Because 5 ohm 10w is not available in my place

[@LahisTechLT]

Taufiq check online: otherwise those will get too much hot and will burn.

[@imtaufiqmehedi]

Ok, thank you

[@JakeJoris]

@@imtaufiqmehedi yes you can, 20w resistors heat up less than 10w ones.

[@Stick_manvideomaker7]

You should connect 2 wires from input positive and negative to output positive and negative so then you will be able for get the know well correct current for fast charger mobile phone adaters otherwise always you will mensure incorrect and less current ;) and thanks to sorin for this nice idea. .

[@LahisTechLT]

not the inputs; data pins should be connected together as shown in my video. (two green wires)

good job bro

[@LahisTechLT]

Thank you

[@tinmisho428]

You still from sorin

Nice

You are amazed? The guy builds his own electronics :)

This is a rip-off. The original design kzbin.info/www/bejne/hIHJmKydrduVh8U

[@MikeTechnology]

Well indeed both of them look verry similar. And I was sure sorin was the author
