Soshine E4 with more detailed LCD (temperature, voltage and current):
http://www.tomopowerbank.com/shop/epilot-e4/

The seller do not ship to Denmark (Shipping would probably be way to expensive anyway) and I could not find it on Aliexpress or Abay

The Tomo Epilot E4 is available from Gearbest (black is a few cents cheaper than white); maybe there’s a generic coupon code somewhere to bring down the price…

https://www.gearbest.com/chargers/pp_1319856.html

I saw a cheaper price for the Epilot E4, but I’m not familiar with the following online store, and whether they ship or not…

While searching for the Tomo powerbanks, I came across other models too:

Tomo D2 (2x 26650) powerbank/charger:
https://www.gearbest.com/chargers/pp_1524290.html
(specs list the input current @ 1A ; it will take a long time to fully charge 2x 5000+ mAh 26650 with this powerbank…)

YZXStudio ZY1280

USB power meter/tester thread - YZXStudio, Power-Z, RDTech and more. USB Power Devices

The new ZY1280 appears to be the upgrade from the ZY1276 / ZY1276P(Plus?). The ZY1278 appears to just be the USB-C (only) version of the ZY1276. Check the official YZXStudio store in TaoBao here: https://item.taobao.com/item.htm?id=549902607690 using Google Translate to translate the marketing blurb for the new meters:

Specifically the LeTV QC3.0+MTKPE version (note: this is the YZXstudio store).

Finally there might be a quality MTKPE charger with at least 2A output at 12V.

EDIT:
This one seem even better, it offers the full 2.4A at 12V with MTKPE and you can even change the plug type:

Hi HKJ

I would be really interested in your review of the Armytek Handy C1 pro. It looks like an excellent everyday or travel charger, at least on paper.

Dear HKJ

Would you be able to review this?

China wholesale Sitemap, dropshIP wholesale from China, Professional Chinese wholesaler for general merchandise on wholesale price.

Also, after reading your testing methodology, I still cannot understand how you perform the “USB coding test” to determine if it has AUTO CODING capability or not. Is there some device that can test that?

Also besides using an oscilloscope, any way we can test the noisiness of the power supply?

Many thanks & regs

YZXStudio ZY1280 and ZL1100 are good for that, then scay for many protocols and list what is supported. Earlier I used a home made device that changed the voltage on the data pins, on the response I could see if it was auto coding.

Also besides using an oscilloscope, any way we can test the noisiness of the power supply?

A AC milivoltmeter, but bandwidth is important, something that just works to a few kHz is not good enough.

What kind of specs should have an oscilloscope for this job? I ask because the price for the cheapest is around 20 USD (DSO138) but I don`t know if is good enough.

You either have to use fully shielded setup (Cable from charger to scope is shielded) or you need to run you scope on batteries. I do the last and some of the noise is common mode noise from the charger.
The scope needs bandwidth enough, 10MHz would be fine for most cases and a input sensitivity that can can see the noise. I usual record two traces, the one I publish and another one with better sensitivity to read the actual noise level.
