Hi HKJ,
I’d like a slim, small capacity powerbank, around 3-4000 mAh or so. I’m considering building recycling a smartphone lipo, but I’m also having a look to ready options… these two for example could be interesting, in case you are interested in reviewing them:
Hmm, just my opinion, regarding the low-cost small-capacity powerbanks,
I think there are too many such kinds it may not be possible to do that much “stringent” testing on them — low-cost unbranded items tend to not have that much quality control and while one batch may perform better, the next batch may easily change… at least based on my experience of them. Just my 2 cents worth…
Actually, I have something that looks practically the same as your second link (the one here: https://www.gearbest.com/power-banks/pp_436972.html), someone passed it on to me (my relative got it as a “giveaway” souvenir from some club event).
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
They are marked as “discontinued” and “out of stock”
[quote=HKJ]
On eBay and from canadian seller it’s available:

I searched for “Tomo E4” and did not get any matches.
I have ordered it.
I like to suggest following devices for review:

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…)

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. 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:

YZX usb meter is very good, but the price is too higher …
but RD (ruideng meter ) is cheaper and have more function.

and
APP and PC software can export data by excel. it is easy to research the data…
but YZX meter did not have ,
For UM34C, it support USB 3.0 and Quick charge recognition mode:QC2.0、QC3.0、APPLE 2.4A/2.1A/ 1A/0.5A、Android DCP、SAMSUNG, support support OPPO phone VOOC, OnePlus DASH
Though UM34C and UM25C have Type-c port , but there is not trigger, only support type-c charge, not recognition
although for data or some function, it is not better than YZX meter, but for the price , it is already best …
for USB load, there are many choice , LD25/LD35
If someone need more cheaper meter, but colorful display, there is also choice
AT34
Waiting for everyone to discuss …
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 ….
