I searched for “Tomo E4” and did not get any matches.
I have ordered it.

Good list, I will definitely get some of the stuff on it. I have not decided how much yet.
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…

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…)
Tomo K2 powerbank/charger/flashlight (2x18650):
https://www.gearbest.com/chargers/pp_009791773690.html
I like to suggest these USB power supplies:

YZXStudio ZY1280
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.

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.
12 USD ? wawo , too expensive, in china , it is about 1.5-3 usd for this same things ….
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.
I do not like is the $10 shipping charge.
Would love to see you review this one HKJ: https://www.aliexpress.com/item/LVSUN-QC-3-0-quick-All-in-1-phone-tablet-charger-laptop-adapter-with-type-c/32814356965.html
4 Quick charge 3.0 ports, 1type-c PD port with 60W output!
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
Would love to see you review this one HKJ: Page Not Found - Aliexpress.com
4 Quick charge 3.0 ports, 1type-c PD port with 60W output!
I have a problem testing 4 quick charge at a time and also more than 4 independent ports.
Would you be able to review this?
I have ordered one.
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?
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.
That’s the wrong thread for chargers - they have their own thread:

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

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.
