Your Charger May be fake!--How to test the quality of your chargers with UM25C and HD35

UM25:www.aliexpress...
HD25/HD35:www.aliexpress...
if you have USB-C charger, use the TC66/TC64 to test, the test way is same
TC66C: www.aliexpress...
hello, have you ever doubted that if your charger can do like what it says?
for example it shows that it can supports 5V2A but it can only output 5V1A, how do we test it?
we made this video to show you how to test the quality of your chargers with our USB meter and electronic load
there are two ways to test:
1. use the electronic load to adjust the voltage and current to see if the charger can output that value
2. increase the current slowly until the max value, check if the voltage drop more than 0.5V, if so, the quality is not so good.
3.check the temperaure, if it produce a lot heat, the quality is not good as well

Thanks for this video. I just ordered 4 of them. Look forward to doing a video with them for testing power banks that have higher voltage outputs.

thank you, if there is any questions when using them, just contact us

@@rdtech9153 Thank you, I will definitely do that if needed. 👍

If there is no information about a required protocol at the values printed on the charger it should be reachable in the standard USB mode. If it can not offer the promised power, it failed and didn't pass my test.

hello, it is not correct for this, a charger(from normal company not fake charger), usually they will not list the protocol name, they will just said that it supports fast charge mode like 9V2A(for example), normally in this way, it can only be triggered, cannot be adjustable directly in the normal mode

@@rdtech9153 Even it is so as you say, it should get triggert then in QC or PD, which are useable on HD35 for example. And if this doesn't work I don't accept the value on the charger. When I buy such a charger for my phone e.g. Android with QC.2.0, then I expect it has to work also with this phone. It is up to the factory to make the technical specs clear. But, by the way. I search a video which explains the details regarding the trigger functions. You can trigger with the TC66C, but also with HD35. What is the difference? What can be done wrong or which mistakes can be done using the trigger function? Can you recommend such a video or can you make a new one about this issue? It would be very helpful.

@@Pixelpanscher hello, the difference between the meter and load is complex, cannot be explained that in a few words, or you can tell us your purpose, we give you the suitable method

[@Pixelpanscher]

@@rdtech9153 The purpose is just testing of powerbanks and chargers using the trigger functions on both, meter and load. Can you recommend a video where is is explained?

[@rdtech9153]

@@Pixelpanscher hello, you can only choose one device to do the trigger function when testing power bank or charger, you choose TC66 to trigger, then use the normal load mode of HD35, or use the trigger mode of HD35, use tc66 as normal meter to check the voltage and current only, the operation are all in the instruction
