dirt cheap on massive discount. One has to wonder …

I’ve purchased one of these and have been very happy with it. Might be worth a full test.

Dirt cheap when you live in the US, but shipping to EU is $18

Hi HKJ,

Will you please consider reviewing this PSU Doctor?

Interesting device, I have ordered one and hope it works with my phone.
The specifications looks a bit dubious, why 11 ADC channels, I would expect 6 (3xVolt, 3xCurrent) or do they just list MCU specification, including all unused ADC channels. The ADC specification is not the only dubious specification, I am very curious what I can use the DC current consumption specification for (These silly specifications do not make it a bad device in any way).

That is a cool usb charger. I hope it also has Wh logging, can’t see that in the phone screenshots.

this charger looks nice, HKJ, does it catch your interest?

At least somebody send my one some time ago: Review of Charger E-SYB E4

Wait, i didnt find it when searching on google
Thanks man

So xiaomi in my country begin asking customers to reture xiaomi powerbank 10000mah(the one has low price and Quick charge), for checking
So, it must be something wrong with it
Many people reported it fried their IC charge manager in their non-quick charge phones

You mean this one?

Can you point to a place where they are announcing the recall?

Yup, that one
The news was posted on a website written in our language, not sure if you guy can read it
And the return is applied(i guess) only on my country(VietNam)

I must admit I do not really like how all this “charging” protocols stuff is going. Again, a crapload of independently developed charging power management intellectual property to continue filing patents and make people believe in whatever respective sort of cooked bunch of lies, selling the same dog with a flashier collar again. Nearly don't give a sh1te.

Where can I buy an Android device with a slot or two for 18650s?

Cheers fellows ^:)

I guess that everyone would use USB IF PD specifications, things would be too much simpler....

Not really, try reading them: USB Charger (USB Power Delivery) | USB-IF

yeah, i just did before posting. Just read a couple of their PDF, everything is well specified IMHO, also cable losses, and parasitic losses, from what i understand

Everything may be well specified, but that do not make it less complicated. Here I am talking about the new PD specification for USB-C where you need a microprocessor in the cable and in both ends of the connection for the high power settings. This specification could also be used for the old cables in one revision of the standard and there it was even worse.
Something like QuickCharge is much simpler.

All this complexity is not a huge problem when used with a smartphone, tablet or other computer, but for chargers, power banks and all the simple toys it can be a problem.

was about to asking you to elaborate, but now i get your point... but i gues at some point we have to agree on a standard, also the more it gets diffused, the more it will be the common...and ...eventually it will become the normality... anyway i got your point
